Arrangement of the manual
This workshop manual can be used in two different ways. To repair a specic sub-assembly on a chainsaw. To dismantle and reassemble a complete chainsaw. Repairing a specic sub-assembly If a specic sub-assembly on the chainsaw needs to be repaired: 1. Look up the page referring to the relevant subassembly. 2. Follow the instructions under the headings: Removal/Dismantling Cleaning and inspection Retting/Reassembly Dismantling and reassembling the entire chainsaw If the entire chainsaw is to be dismantled, follow the instructions under the heading Removal/Dismantling. Work through the manual and follow the instructions given in each section under the heading Removal/Dismantling. Then follow all the Cleaning and inspection instructions in each section. Working from the back of the manual, follow all the instructions under the headings Retting/Reassembly in reverse order. Each of the sections covering removal/dismantling and retting/reassembly include the relevant lubrication instructions and bolt torques for each stage of repair.
These pages describe the most common faults that affect a chainsaw. They are divided into four different groups with the most likely faults described rst.
The section that describes how to repair the chainsaw consists of detailed, step-by-step instructions. It explains in detail the special tools, lubricants and bolt torques that are needed when working on each component.
This workshop manual covers the following chainsaw models: 346XP 353
Construction and function
This chapter gives a simple description of the chainsaw carburettor and its various parts.
This workshop manual gives detailed instructions on how to troubleshoot, repair and test a chainsaw. This section also describes the various safety precautions that should be taken when carrying out repairs. The workshop manual has been written for personnel who are assumed to have general experience of repairing and servicing chainsaws. Workshops where chainsaws are repaired must be equipped with safety equipment that meets local regulations. No-one should carry out repairs on a chainsaw until they have read and understood the contents of this workshop manual. Chainsaws are type-approved to meet the relevant safety legislation, but this only applies when the saw is tted with the cutting equipment specied in the users manual. The tting of any other equipment, or of accessories or parts that are not approved by Jonsered, could mean that the saw no longer meets these safety requirements and the person who carried out the work may be held responsible for its non-conformance. In this workshop manual the following boxes indicate where caution should be taken.
The fuel that is used in a chainsaw poses the following hazards: The fuel and its fumes are toxic. May cause irritation to skin or eyes. May cause breathing difculties. Highly ammable. When using compressed air the air jet should never be pointed at the body. Air can be forced into the bloodstream and cause fatal injury. Wear ear protection when testing saws. After testing a saw do not touch the silencer until it has cooled down. The silencer gets very hot and you may burn yourself. Wear protective gloves when working on the silencer. The guide bar, chain and clutch cover (chain brake) must be tted before the saw is started. If not, the clutch may come loose and cause injury. Poor chain lubrication can result in failure of the chain, which could cause serious or fatal injury. Take care to ensure that the spring inside the starter assembly does not y out and cause injury. Wear eye protection. If the spring is under compression when the pulley is removed it could y out and cause injury. Before removing the tensioning spring from the chain brake, ensure that the brake is in the on position, otherwise the spring may y out and cause injury. After completing the repair the chain brake must be tested, see Chain brake reassembly \ Operating test. Always consider the re risk. A chainsaw can produce sparks that could start a re. Inspect the chain catcher and replace it if it is damaged.
In idling mode the throttle valve (F) is closed. Air is sucked through an aperture in the throttle valve and a small amount of fuel is supplied through the diffuser jet (E).
In part throttle mode the throttle valve (F) is partially open. Fuel is supplied through the diffuser jets (E).
In full throttle mode both valves are open and fuel is supplied through all the diffuser jets (E).
The various faults that can affect a chainsaw are divided into four groups. In each group the likely symptoms are given on the left and possible causes are listed on the right. The most likely faults are given rst, and so on.

Chain catcher replacement
If the chain catcher is worn it must be replaced with a new one. Remove the cylinder cover, silencer support, silencer, gasket and cooling plate. 2 If the saw is tted with a spark arrestor mesh this must also be removed. 1 Release the brake by pushing the kickback guard backwards. Undo the guide bar bolts and remove the clutch cover, chain and guide bar. 2
Clean and inspect all parts carefully. If there are any cracks or other defects replace the damaged parts with new ones. The spark arrestor mesh is best cleaned with a wire brush. If the mesh is damaged it must be replaced. If the mesh is blocked the saw will overheat and this will cause damage to cylinder and piston. Never use the saw with a silencer that is in poor condition. Always use original parts.
Remove the chain catcher and replace it with a new one. Check that the vibration damping spring locates correctly against the crankcase when you bolt the new chain catcher in position. A worn (damaged) chain catcher on 340, 345 or 350 can be replaced with the same chain catcher as 346XP, 351 and 353 (see gure above). 3 Turn the chain tensioner anticlockwise as far as it will go. Ret: guide bar chain clutch cover
Stop switch removal
1 Remove the cylinder cover and air lter. 2
Clean and inspect all parts carefully. If there are any cracks or other defects replace the damaged parts with new ones. Always use original parts.
Stop switch resistance measurement
Clean the mating surfaces and check the resistance as follows:
Disconnect both leads from the stop plate and stop switch. Remove the stop plate by carefully sliding it over the lug on the front mounting. 3
Measure the resistance by connecting a multimeter to the ignition coil. NOTE! The switch must be in the on position to give the correct reading. The resistance must not be higher than 0.2 ohm when the switch is in the on position.
Carefully prise the carburettor assembly off the lefthand rubber mounting using a small screwdriver. 4
Carefully prise the stop switchs upper mounting off the air lter holder while lifting the switch to release it from the lower mounting.
Stop switch retting
Choke control removal
1 Remove the cylinder cover, air lter and stop switch. Disconnect the fuel hose from the carburettor. NOTE! Do not use knurled pliers to disconnect or reconnect the fuel hose. This could damage the hose and lead to leakage or fracture. 2

Then ret: cable guide and press the leads into position HT lead starter assembly, tighten to a torque of 2.53.5 Nm cylinder cover
To ret the ignition module proceed as follows: Turn the ywheel so that the magnets are in line with the ignition module. Fit the ignition module with the plastic feeler gauge (34-01) held in position at the same time, without tightening the bolts. Connect the black earth lead to the front screw on the ignition module. Adjust the gap between the ignition module and magnet to 0.3 +/- 0.1 mm. The gap must be measured at either of the two lowest pegs on the ignition module. Tighten the bolts to 4.56 Nm. Connect the blue lead to the ignition module.
Centrifugal clutch removal
1 Remove the cylinder cover. Disengage the chain brake by pushing the kickback guard backwards. Undo the guide bar bolts and remove the clutch cover, chain and guide bar. 2
Inspection and cleaning
Clean and inspect all parts carefully. If there are any cracks or other defects replace the damaged parts with new ones. Always use original parts.
Check the thickness of the clutch shoes by using vernier callipers to measure the diameter of the clutch. If the diameter is less than 65 mm the clutch assembly must be replaced. Disconnect the HT lead. Remove the spark plug and t piston stop 15-01 in its place. 3
Centrifugal clutch retting
1 NOTE! Handle the clutch springs carefully. If they are opened up too much they could damage the saw.
Unbolt the clutch using tool 16-01 and a suitable socket or combination spanner. Turn the nut clockwise to remove it. 4 NOTE! Handle the clutch springs carefully. If they are opened up too much they could damage the saw.

If necessary, the lever arm can be bent slightly. 7 Fit the metering diaphragm with its gasket and ret the cover to the metering unit. 8 Carry out pressure testing.
The item numbers in the diagram refer to the steps below (18).
Carburettor pressure testing
Pressure testing should be carried out with the carburettor fully assembled. Testing should always be carried out after the carburettor has been repaired, but can also be performed for troubleshooting before dismantling. Carry out the test as follows: Screw in the high and low speed jet screws and back them off one turn. Connect pressure tester 38-01 to the carburettor fuel inlet.
NOTE! Cleanliness is very important when reassembling the carburettor. Tiny particles of dirt can cause operating problems. 1
Fit stop plate 17-01 between the carburettor ange and the insulating plate. Lower the carburettor into a beaker of water. Pump up the pressure to 50 kPa (0.5 bar) and clamp the pump tube. There should be no leakage. If leakage occurs, refer to the table below.

The L and H jets adjust the fuel ow to match the airow that the throttle valve opening allows. Turning them clockwise makes the fuel/air mixture weaker (less fuel in relation to the amount of air) and turning them anti-clockwise makes the fuel/air mixture richer. A weak mixture increases the engine speed and a rich mixture decreases the engine speed. The T screw controls the throttle position when idling. Turning the T screw clockwise gives faster idling; turning it anti-clockwise lowers idling speed. WARNING! The guide bar, chain and clutch cover must be tted before the saw is started, otherwise the clutch may y off and cause injury. Basic settings and running in During testing at the factory the carburettor is adjusted to the basic factory settings. The factory settings are H = 1 turn and L = 1 turn. To ensure that engine components receive adequate lubrication (running in) the carburettor should be set to a somewhat richer fuel mixture for the chainsaws rst 3-4 running hours. This is done by adjusting the maximum speed to 6-700 rpm less than the recommended maximum speed.
Basic requirements Before making any adjustments the air lter should be clean and the cylinder cover should be in place. If the carburettor is adjusted with a dirty air lter, the mixture will be too weak next time the air lter is cleaned. This can cause serious engine damage. Carefully screw in the L and H jets fully, then back them off 1 turn. The carburettor now has the settings H = 1 and L = 1. Start the chainsaw and allow it to warm up for 10 minutes. Place the saw on a at surface so that the guide bar is pointing away from you and the guide bar and chain are not touching the surface. Low speed jet L Find the highest idling speed by slowly screwing the L screw in and then out again. When the highest speed has been found, screw out the L screw 1/8 - 1/4 turn.
Repair instructions Fine adjustment of idling speed T The idling speed is adjusted using the screw marked T. If adjustment is necessary, screw in the idling screw T until the chain starts to turn. Then screw it out until the chain stops moving. The idling speed is correctly set when the engine runs smoothly in all positions and there is a clear margin to the speed at which the chain starts to move. High speed jet H The high speed jet H inuences the saw power output and engine speed. If the H jet is set too weak the saw will over-rev, which could cause engine damage. Run the saw at full throttle for about 10 seconds. H=1. Then screw out the H screw 1/4 turn. H=1 1/4. Run the saw again at full throttle for about 10 seconds and listen to the difference in the engine note. Repeat this procedure again with the H screw screwed out another 1/4 turn. H=1 1/2. You have now run the saw at settings H 0, H = +1/4 and H = +1/2 from the factory setting. At full throttle the engine will sound different at each setting. The H screw is correctly adjusted when the saw burbles a little at full throttle without any load. If there is a lot of smoke from the silencer and the saw does not run smoothly then the setting is too rich. Screw in the H screw to the setting that sounds right. NOTE! For optimum adjustment, a tachometer should be used. The recommended maximum speed should not be exceeded. Carburettor correct adjustment When the carburettor is correctly adjusted the saw should accelerate without hesitation and the engine will burble a little at full throttle without any load. The chain must not turn when idling. If the L screw is set too weak this can make the saw difcult to start and cause poor acceleration. If the H screw is set too weak the saw will produce less power, poor acceleration and there is a risk of engine damage. If either the L or H screws are set too rich it will cause acceleration problems or too low working speed.
Fuel tank removal
WARNING! The fuel used in chainsaws is harmful if inhaled, may cause skin irritation and is highly ammable. 1 Empty the fuel tank. 2 Remove the following: cylinder cover air lter clutch cover chain and guide bar starter assembly cable guide 3 Disconnect the fuel hose from the carburettor. 4
Disconnect the pushrod from the carburettor by rst carefully prising up the spring over the end of the rod, where it connects to the throttle lever (A). Then press the throttle lever forwards (B) while pressing the throttle pushrod backwards (C) and lifting it off the lever. Withdraw the throttle pushrod from the tank and lift it upwards without pulling it through the rubber inlet manifold.
Carefully check that: there are no leaks from the fuel tank there are no leaks from the tank ller cap the fuel hose is undamaged and free from wear the fuel lter is not clogged the tank vent is not blocked or leaking the vibration damping springs and stops are not damaged
Replacing the fuel lter
NOTE! Do not use knurled pliers to disconnect or reconnect the fuel hose. This could damage the hose and lead to leakage or fracture. 1 First remove the old fuel lter from the tank unit using special tool 83-01. 2 Pull the fuel hose out of the tank and pull off the lter. Unscrew both stops and the three vibration damping springs from the ywheel side and clutch side of the engine. Fit the new fuel lter and feed the fuel hose back into position.
Replacing the fuel hose
NOTE! Do not use knurled pliers to disconnect or reconnect the fuel hose. This could damage the hose. 1 Before replacing the fuel hose, measure the length of hose between the crankcase and carburettor and between the tank and crankcase. The correct hose length between the tank and crankcase is 43 mm (1.69 inches). The correct hose length between the crankcase and carburettor is 53 mm (2.09 inches). 2 Remove the fuel hose from the fuel tank using tool 83-01. Trim off 5 mm (0.20 inches) from the mitred end of the hose. Fit the fuel lter and reinsert the hose in the tank.
Disconnect and remove the fuel hose from the crankcase.
Tank vent testing
Connect pressure gauge 38-01 to the fuel hose. Pump the pressure up to 50 kPa (0.5 bar). The pressure should drop to 20 kPa (0.2 bar) within 60 seconds. 2
Fit the throttle pushrod in the tank and connect it to the carburettor. Ret the spring. 4
Use gauge 37-01 to measure vacuum. Readings should be as follows: the vacuum should increase from 30 to 15 within 30 seconds. If readings are outside this range the vyon plugs must be replaced.
Connect the fuel hose to the carburettor. Check that the hose is not kinked or too long to be clamped between the crankcase and tank. The correct hose length between the tank and crankcase is 43 mm (1.69 inches). The correct hose length between the crankcase and carburettor is 53 mm (2.09 inches) excluding the mitred section. 5
Fuel tank retting
1 Insert the fuel hose into the carburettor chamber. Ret the fuel tank. 2
Connect the fuel hose to the carburettor. 6 Then ret: cable guide starter assembly (2.53 Nm) chain and guide bar clutch cover air lter cylinder cover

Decompression valve pressure testing
NOTE! If a new crankshaft has been tted the saw must be run in for 3-4 hours with the carburettor adjusted to the factory settings.
Repairing damaged threads
A repair kit, 33-01, is available for repairing damaged threads. First drill out the hole using: 6.1 mm drill bit for magnesium crankcase Then screw in the thread insert using a suitable bolt and spanner.
Guide bar bolts replacement
1 Drain the oil tank. 2 Knock through the old guide bar bolt so that it falls into the oil tank. 3 Remove the bolt from the oil tank. 4
A damaged thread can be repaired using a thread insert. The slotted part of the thread insert is screwed in rst, as this is the cutting part. To repair a thread that was originally designed for a PL5 screw: rst drill out with a 6.1 mm diameter drill bit, then screw in the thread insert using a suitable screw and spanner. To repair a thread that was originally designed for a MT6 screw: rst drill out with a 7.1 mm diameter drill bit, then screw in the thread insert using a suitable screw and spanner. This type of thread insert is best suited for use in plastic and magnesium, but not for repairing threads in aluminium. In that case use a helicoil insert with metric screw. New part no. 39-27 40-01 Description PL5 MT6
Fasten a steel wire to the thread of the new bolt, feed the steel wire into the oil tank and out through the bolt hole in the crankcase. 5 Pull the steel wire until the bolt comes out through its hole. 6 Pull through the bolt with its nut. Place a spacer between the nut and crankcase. 7 Check that the square shoulder of the bolt is correctly seated in the recess in the crankcase. 8 Rell with chain oil.
Basic adjustment for EPA II carburetors
After replacing the carburetor or high speed and/or low speed needle on an EPA (The US Environmental Protection Agency) certied product a basic adjustment must be carried out as described below in order to meet the EPA-requirements. This to achieve as low emissions as possible. This instruction is made for USA & Canada only. On EPA carburetors both the H- and L-needles are tted with caps to prevent the chain saw operator from changing the adjustment above EPA standard. The caps can be removed to achieve richer or leaner adjustments. To set the needles correctly an adjustment sleeve is tted from the factory over the caps to lock them in maximum allowed settings. When correctly set the caps must be xed on the needles. The adjustment sleeve then can be removed. Over the caps on complete sparepart carburetor, there is a plastic sleeve which is intended to lock the caps at the richest position (anticlockwise towards stop) during the time that the needles are adjusted. When the adjustment is complete and the caps have been xed on the needles, the sleeve is no longer of any function and can be removed. NOTE! On the complete spare part carburetor, the Lneedle is adjusted from the factory. NOTE! Before making any adjustments the following must be done! Mount, for this model, approved bar & chain combination (See Technical data in the Operators manual). Model 340/345/350 346XP/16 5. Let the engine run at B rpm ~ 1 minute, until warm. 6. Adjust the H-needle to a top speed of C rpm. Model 340/345/350/351 346XP C = C = 14 300

How to Mow
Your product can be used to cut grass using the following methods:1. Grassbox Fitted:- grass is collected effectively and compacted into the grassbox. (K) 2. Rear Discharge:- Effectively cuts long grass with no need to empty the grassbox (L) 3. Mulch Plug Fitted:- grass cuttings are finely chopped to return nutrients to your lawn (M). See Mulching Plug on page 7. How to Mow 1. Start mowing the edge of the lawn nearest to the power point so the cable is laid out on the lawn you have already cut. 2. Mow twice a week during the growing season, your lawn will suffer if more than a third of its length is cut at one time and this may also result in poor collection. Do Not Overload Your Mower Mowing long thick grass may cause the motor speed to drop, you will hear a change in the motor sound. If the motor speed drops you may overload your lawnmower which may cause damage. When mowing in long thick grass a first cut with the cutting height set higher will help reduce the load. See Cutting Height Adjustment.
Grassbox Full Window
As the grassbox fills up, grass will be visible through the window (N). When the window/grassbox is full it is time to empty the grassbox.

Lift safety flap and insert the mulching plug into rear discharge chute. (P2) ensuring it is securely fitted. (P3) 4. The mulching plug prevents grass from being collected by blocking the collection chute on the underside of the deck. (P4)
Cutting Height Adjustment
Cutting Height Adjustment Height of cut is adjusted by raising or lowering the wheels using the height adjustment lever (Q) There are five heights of cut on this product. NOTE A medium height of cut is recommended for most lawns. The quality of your lawn will suffer and collection will be poor if you cut too low.
