SAFETY PRECAUTIONS
Intended use Power chain saws This power chain saw may be used only for sawing wood out of doors. It is intended for the followung uses depending on its class: Professional and mid-class: Use on small, medium and large trees: felling, limb removal, cutting to length, thinning. Hobbyklasse: Occasional use on small trees, fruit-tree care, felling, limb removal, cutting to length. Protective gloves (6) made of thick leather are part of the prescribed equipment and must always be worn during operation of the chain saw. During operation of the chain saw safety shoes or safety boots (7) tted with anti skid sole, steel toe caps and protection for the leg must always to be worn. Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing.
Unauthorised users: Persons who are not familiar with the Instruction Manual, children, young people, and persons under the inuence of drugs, alcohol or medication must not use this saw. General precautions To ensure correct operation the user has to read this instruction manual to make himself familiar with the characteristics of the chain saw. Users insufciently informed will endanger themselves as well as others due to improper handling. It is recommended to lend the chain saw only to people who are experienced in working with chain saws. Always hand over the instruction manual. First users should ask the dealer for basic instructions to become familiarized with the characteristics of engine powered sawing or even attend a recognized course of instruction. Children and young persons aged under 18 years must not be allowed to operate the chain saw. Persons over the age of 16 years may, however, use the chain saw for the purpose of being trained as long as they are under the supervision of a qualied trainer. Use chain saws always with the utmost care and attention. Operate the chain saw only if you are in good physical condition. If you are tired, your attention will be reduced. Be especially careful at the end of a working day. Perform all work calmly and carefully. The user has to accept liability for others. Never use the chain saw after having consumed alcohol, drugs or medication. A re extinguisher must be available in the immediate vicinity when working in easily inammable vegetation or when it has not rained for a long time (danger of re).

Protective equipment In order to avoid head, eye, hand or foot injuries as well as to protect your hearing the following protective equipment must be used during operation of the chain saw: The kind of clothing should be appropriate, i. e. it should be tight-tting but not be a hindrance. Do not wear jewellery or clothing which could become entangled with bushes or shrubs. If you have long hair, always wear a hairnet! It is necessary to wear a protective helmet whenever working with the chain saw. The protective helmet (1) is to be checked in regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets. The face shield (2) of the protective helmet (or the goggles) protects against sawdust and wood chips. During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries. Wear adequate noise protection equipment (ear muffs (3), ear plugs, etc.). Octave brand analysis upon request. The safety jacket (4) is provided with special signal-coloured shoulder straps and is comfortable and easy to care for. The protective brace and bib overall (5) is made of a nylon fabric with 22 layers and protects against cuts. We strongly recommend its use.

Fuels / Refuelling

Stop the engine before refuelling the chain saw. Do not smoke or work near open res (5). Let the engine cool down before refuelling. Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products. Always wear protective gloves when refuelling. Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapours can be hazardous to your health. Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them ot once. Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base. Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the oor (explosion hazard). Ensure to rmly tighten the screw caps of the fuel and oil tanks. Change the place before starting the engine (at least 3 m from the place of refuelling) (6). Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future. Use only approved and marked containers for the transport and storage of fuel and chain oil. Ensure children have no access to fuel or chain oil. Do not work on your own. There must be someone around in case of an emergency (within shouting distance). Ensure that there are no children or other people within the working area. Pay attention to any animals in the working area, as well (7). Before starting work the chain saw must be checked for perfect function and operating safety according to the prescriptions. Check especially the function of the chain brake, the correct mounting of the guide bar, the correct sharpening and tightening of the chain, the rm mounting of the sprocket guard, the easy motion of the throttle lever and the function of the throttle lever lock, the cleanliness and dryness of the handles, and the function of the ON/OFF switch. Start the chain saw only after complete assembly and inspection. Operation of the device is only permitted after all the appropriate accessories are attached! Before starting the chain saw ensure that you have a safe footing. Put the chain saw into operation only as described in this instruction manual (8). Other starting methods are not allowed. When starting the chain saw it must be well supported and securely held. The guide bar and chain must not be in contact with any object. When working with the chain saw always hold it with both hands. Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your ngers. CAUTION: When releasing the throttle lever the chain will keep on running for a short period of time (free-wheeling). Continuously ensure that you have a safe footing. Hold the chain saw such that you will not breathe in the exhaust gas. Do not work in closed rooms (danger of poisoning). Switch off the chain saw immediately if you observe any changes in its operating behavior. The engine must be switched off before checking the chain tension, tightening the chain, replacing it or clearing malfunctions (9). When the sawing device is hit by stones, nails or other hard objects, switch off the engine immediately and check the sawing device. When stopping work or leaving the working place switch off the chain saw (9) and put it down such that nobody is endangered. Do not put the overheated power chain saw in dry grass or on any inammable objects. The mufer is very hot (danger of re). CAUTION: Oil dropping from the chain or guide bar after having stopped the saw chain will pollute the soil. Always use an appropriate base.

Kickback

- When working with the chain saw dangerous kickbacks may occur. - Kickback occurs when the upper part of the end of the guide bar inadvertently touches wood or other hard objects (10). - This causes the saw to be thrown back toward the user with great force and out of control. Risk of injury! In order to prevent kickback, follow these rules: - Only specially-trained persons should perform plunge cuts, i.e., piercing timber or wood with the tip of the saw! - Always observe the end of the guide bar. Be careful when continuing an already started cut. - When starting to cut the chain must be running. - Ensure that the chain is always sharpened correctly. Pay special attention to the height of the depth limiter. - Never cut several branches at the same time. When cutting a branch ensure that no other branch is touched. - When crosscutting a trunk be aware of the trunks next to it.
Working behavior/Method of working
Only use the chain saw during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping). The risk of slipping is extremely high when working on recently peeled wood (bark). Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing. Never saw above your shoulder height (11). Never saw while standing on a ladder (11). Never climb up into trees to perform sawing with the chain saw. Do not work leaning too far over. Guide the chain saw in such a way that no part of your body is within the elongated swivelling range of the saw (12). Use the chain saw for sawing wood only. Avoid touching the ground with the chain saw while it is still running. Never use the chain saw for lifting up or removing pieces of wood or other objects. Remove foreign objects such as sand, stones and nails found within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback. When sawing precut timber use a safe support (sawing jack, 13). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it. Secure round pieces against rotation. For cutting down trees or performing crosscuts the spike bar (13, Z) must be applied to the wood to be cut. Before performing a crosscut rmly apply the spike bar to the timber, only then can the timber be cut with the chain running. For this the chain saw is lifted at the back handle and guided with the tubular handle. The spike bar serves as a centre of rotation. Continue by slightly pressing down the tubular handle and simultaneously pulling back the chain saw. Apply the spike bar a little bit deeper and once again lift the back handle. When the timber must be pierced for cutting or longitudinal cuts are to be performed it is urgently recommended to have this carried out by specially trained persons only (high risk of kickback). Do longitudinal - lengthwise - cuts at the lowest possible angle (14). Be very careful when doing this type of cut, as the spike bar cannot grip. The saw must be running whenever you remove the chain saw from the wood. When performing several cuts the throttle lever must be released in between.

Transport and storage

When changing your location during work switch off the chain saw and actuate the chain brake in order to prevent an inadvertent start of the chain. Never carry or transport the chain saw with the chain running. When transporting the chain saw over long distances the guide bar protection cover (delivered with the chain saw) must be applied. Carry the chain saw with the tubular handle. The guide bar points backwards (20). Avoid coming in contact with the mufer (danger of burns). Ensure safe positioning of the chain saw during car transportation to avoid fuel or chain oil leakage. Store the chain saw safely in a dry place. It must not be stored outdoors. Keep the chain saw out of reach of children. Before storing the chain saw over a long period of time or shipping it the fuel and oil tanks must be completely emptied. 20

Maintenance

Before performing maintenance work switch off the chain saw (21) and pull out the plug cap. Before starting work always check the operating safety of the chain saw, in particular the function of the chain brake. Make sure that the chain is always sharpened and tightened correctly (22). Operate the chain saw only at a low noise and emission level. For this ensure the carburetor is adjusted correctly. Regularly clean the chain saw. Regularly check the tank cap for tightness. Observe the accident prevention instructions issued by trade associations and insurance companies. Do not perform any modications on the chain saw. You will put your safety at risk. Perform only the maintenance and repair works described in the instruction manual. All other work must be carried out by DOLMAR Service. Use only original DOLMAR spare parts and accessories. Using spare parts other than original DOLMAR parts or accesories and guide bar/chain combinations or lengths which are not approved bring a high risk of accidents. We cannot accept any responsibility for accidents and damage resulting from using sawing devices or accesories which have not been approved. 22 21

PUTTING INTO OPERATION

CAUTION:

Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves!
Start the chain saw only after having assembled it completely and inspected!
Mounting the guide bar and saw chain
Use the universal wrench delivered with the chain saw for the following work.
Put the chain saw on a stable surface and carry out the following steps for mounting the guide bar and chain: Release the chain brake by pulling the hand guard (1) in direction of arrow. Unscrew retaining nuts (2). Pull off the sprocket guard (3).
Turn the chain adjusting screw (4) to the left (counterclockwise) until the pin (5) is at the left stop.
Position the guide bar (6). Make sure that the pin (7) of the chain tightener is in the hole on the guide bar.
Lift the chain (8) over the sprocket (9). Using your right hand, guide the chain into the top guide groove on the guide bar (10). Note that the cutting edges along the top of the chain must point in the direction of the arrow (11)!
Pull the chain (8) around the sprocket nose (12) of the guide bar in the direction of the arrow.
Replace the sprocket guard (3), putting the chain (8) over the chain catcher (13). Manually tighten the retaining nuts (2).

Tightening the saw chain

Turn the chain tightener (C/4) to the right (clockwise) until the chain engages the guide groove of the bottom side of the bar (see circle). Slightly lift the end of the guide bar and turn the chain adjusting screw (C/4) to the right (clockwise) until the chain rests against the bottom side of the guide bar. While still holding up the guide bar, tighten the retaining nut s(2) with the universal wrench.
Checking the chain tension
The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand. While doing so the chain brake must be released. Check the chain tension frequently - new chains tend to get longer during use! When checking the chain tension the engine must be switched off. NOTE: It is recommended to use 2-3 chains alternatively. In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain.
Turn the retaining nuts (2) approximately one turn with the universal wrench. Slightly lift the end of the guide bar and turn the chain adjusting screw to the right (clockwise) until the chain rests against the bottom side of the guide bar. While still holding up the guide bar, tighten the retaining nuts (2) with the universal wrench.
The PS-34, PS-45 comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 6), the chain brake will stop the chain through inertia if the kickback is sufciently strong. The chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency. IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see Checking the chain brake)! Doing so can very quickly cause extensive engine damage! ALWAYS release the chain brake before starting the work!

Checking the chain brake

Do not work with the chain saw without rst checking the chain brake! Start the engine as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact). Grasp the tubular handle rmly with one hand and hold the grip with the other. With the engine running at moderate speed, press the hand guard (7) in the direction of the arrow with the back of your hand until the chain brake engages. The chain should stop immediately. Immediately release the throttle and release the chain brake. IMPORTANT: If the chain does not stop immediately when you test the chain brake, do NOT use the chain saw. Take the chain saw to a DOLMAR service center.

Adjusting the carburetor

IMPORTANT: Carburetor adjustment may be done only by a DOLMAR service centre! Setting the idle speed Turn out the idle adjusting screw (9) (counterclockwise): Idle speed drops. Turn in the idle adjusting screw (9) (clockwise): Idle speed goes up. Caution: If after this adjustment the cutting tool still rotates during idle, do NOT work with the unit! Take it to a DOLMAR service centre!
Do not undertake adjustments to the adjusting screws (H) and (L) without a tachometer! Improper adjustment can lead to engine damage! The adjusting screws (H) and (L) are factory set almost all the way out (turned counterclockwise). A tachometer is necessary to adjust the adjusting screws (H) and (L), because exceeding the permissible maximum speed leads to overheating and under-lubrication. This can damage the engine! The only user-adjustable setting is the idle adjusting screw (9). If the blade rotates in idle (without the throttle pressed), it is absolutely necessary to correct the idle speed before using the tool! Do not adjust the idle speed until the machine has been completely assembled and checked! Adjust the idle speed only with the engine warm, a clean air lter, and properly installed cutting tool. Use a screwdriver (blade width 4 mm, part No. 001) to adjust the screw. Note: Carburetor adjustment is necessary for optimum engine performance, for safer and more economical operation. In order to comply with new emissions legislation, limits have been placed on the carburetor adjusting screws (H) and (L). This limitation (to about 180 degrees) prevents an excessively rich mixture. On some models the (H) screw is also sealed. This ensures compliance with emissions rules as well as optimum engine performance and economical fuel consumption.

MAINTENANCE

Sharpening the saw chain
CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves! The chain needs sharpening when: The sawdust produced when sawing damp wood looks like wood our. The chain penetrates the wood only under great pressure. The cutting edge is visibly damaged. The saw is pulled to the left or right when sawing. This is caused by uneven sharpening of the chain. Important: Sharpen frequently, but without removing too much metal! Generally, 2 or 3 strokes of the le will be enough. Have the chain resharpened at a service centre when you have already sharpened it yourself several times.

Cleaning the brake band and sprocket interior
CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves! CAUTION: Start the chain saw only after having assembled it completely and inspected!
Remove the sprocket guard (4) (See PUTTING INTO OPERATION gs. A and B) and clean the sprocket interior with a brush. Turn the chain tightener screw (5) to the left (counterclockwise) until you feel resistance. Remove the chain (3) and guide bar (2). NOTE: Make sure that no residue or contaminants remain in the oil guide groove (1) and the chain tightener (6). For replacing the guide bar, chain, and sprocket see PUTTING INTO OPERATION.
NOTE: The chain brake is a very important safety device and like any other component subject to normal wear and tear.
Regular inspection and maintenance are important for your own safety and must be done by a DOLMAR service center.
Cleaning the guide bar, lubricating the sprocket nose
CAUTION: Protective gloves must be worn. Regularly inspect the bearing surfaces of the guide bar for damage, and clean them with a suitable tool. If the saw is used intensively it will be necessary to lubricate the return sprocket bearings regularly (once a week). To do this, rst thoroughly clean the 2 mm hole at the tip of the guide bar, and then press in a small amount of multi-purpose grease. Multi-purpose grease and grease guns are available as accessories. Multi-purpose grease Grease gun (order no. 000) (order no. 000)

Replacing the saw chain

CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! Check the sprocket (7) before mounting a new chain. Remove the sprocket guard (See PUTTING INTO OPERATION gs. A - H). CAUTION: Worn out sprockets (8) may damage the new chain and must therefore be replaced.
Replacing the suction head
The felt lter (9) of the suction head can become clogged. It is recommended to replace the suction head once every three months in order to ensure unimpeded fuel ow to the carburetor. To remove the suction head for replacement, pull it out through the tank ller neck using a piece of wire bent at one end to form a hook.

Cleaning the air lter

Remove the lter cover (11) (3 screws (10)). Remove the air lter (12).
CAUTION: Cover the intake opening with a cloth to prevent dirt particles from getting into the carburetor. CAUTION: To prevent injury to the eyes, do NOT blow out dirt particles! Do not use fuel to clean the air lter. If the lter is very dirty, clean it in lukewarm water with dishwashing detergent. Let the air lter dry completely. If the lter is very dirty, clean it frequently (several times a day), because only a clean air lter provides full engine power. CAUTION: Replace damaged air lters immediately. Pieces of cloth or large dirt particles can destroy the engine!

Replacing the spark plug

CAUTION: Do not touch the spark plug or plug cap if the engine is running (high voltage). Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves!

0,5 mm

The spark plug must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily. Remove the cover (see Cleaning the air lter). Pull the plug cap (1) off the spark plug. Use only the combination wrench supplied with the saw to remove the spark plug. Electrode gap The electrode gap must be 0.5 mm.
Checking the ignition spark
Press the loosened spark plug (2) with the ignition cable rmly connected against the cylinder using insulated pliers (not near the spark plug opening). Press the combination switch (3) in the I position. Pull the starter cable hard. If the function is correct, an ignition spark must be visible near the electrodes. CAUTION: Use only the following spark plugs: NGK BPMR 7A
Instructions for periodic maintenance
To ensure long life, prevent damage and ensure the full functioning of the safety features the following maintenance must be performed regularly. Guarantee claims can be recognized only if this work is performed regularly and properly. Failure to perform the prescribed maintenance work can lead to accidents!
