IMPORTANT SAFETY INSTRUCTIONS
(For All Tools) WARNING: WHEN USING ELECTRIC TOOLS, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL INJURY, INCLUDING THE FOLLOWING: READ ALL INSTRUCTIONS.
1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries. 2. CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp
or wet locations. Keep work area well lit. Don't expose power tools t o rain. Don't use tool in presence of flammable liquids or gases.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
4 STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high.
or locked-up place - out of reach of children. 5. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment t o do the job of a
heavy-duty tool. Don't use tool for purpose not intended.
7. DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering t o contain long hair.
8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is

dusty.

9. DON'T ABUSE CORD. Never carry tool by cord or yank it t o disconnect from
receptacle. Keep cord from heat, oil, and sharp edges.

IO. SECURE

WORK. Use clamps or a vise t o hold work. It's safer than using your hand and it frees both hands t o operate tool.
1 1. DON'T OVERREACH. Keep proper footing and balance at all times. 12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
13. DISCONNECT TOOLS. When not in use, before servicing, and when changing accessories, such as blades, bits, cutters.
14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking t o
see that keys and adjusting wrenches are removed from tool before turning it on. 15. AVOID UNINTENTIONAL STARTING. Don't carry plugged-in tool w i t h finger on switch. Be sure switch is OFF when plugging in.
16. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors and so marked. 17. STAY ALERT. Watch what you are doing, use common sense. Don't operate tool when you are tired. 18. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked t o determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Don't use tool if switch does not turn it on and off. 19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact w i t h grounded surfaces. For example; pipes, radiators, ranges, refrigerator enclosures. 20. REPLACEMENT PARTS. When servicing, use only identical replacement parts. 21. POLARIZED PLUGS. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
VOLTAGE WARNING: Before connecting the tool t o a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source w i t h voltage greater than that specified for the tool can result in SERIOUS INJURY t o the user - as well as damage t o the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source w i t h voltage less than the nameplate rating is harmful t o the motor.

ADDITIONAL SAFETY RULES

1. Handle the bits very carefully. 2. Check the bit carefully for cracks or damage before operation. Replace cracked or damaged bit immediately. 3. Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation. 4. Hold the tool firmly w i t h both hands. 5. Keep hands away from rotating parts. 6. Make sure the bit is not contacting the workpiece before the switch is turned on. 7. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate improperly installed bit. 8. Be careful of the bit rotating direction and the feed direction. (cf. P 7 ). 9. Do not leave the tool running. Operate the tool only when hand-held. IO. Always switch off and wait for the bit t o come t o a complete stop before removing the tool from workpiece. 11. Do not touch the bit immediately after operation; it may be extremely hot and could burn your skin. 12. Keep the bit retracted so as not t o protrude from the tool base except during actual operation.

SAVE THESE INSTRUCTIONS.

Installing or removing router bit CAUTION : Always be sure that the tool i s switched off and unplugged before installing or removing the bit. Insert the bit all the way into the collet cone and tighten the collet nut securely with the two wrenches.
To remove the bit, follow the installation

procedure in reverse.

Tighten
CAUTION : Do not tighten the collet nut without inserting a bit, or the collet cone will break. Adjusting depth of cut Place the tool on a flat surface. Loosen the screw securing the stopper pole.
Loosen the lock lever and lower the tool body until the bit just touches the flat surface. Tighten the lock lever to lock the tool body.
Next, lower the stopper pole until it makes contact with the adjusting hex bolt. Align the depth pointer with the "0" graduation.
Raise the stopper pole until the desired depth of cut i s obtained. The depth of cut is indicated on the scale (1 mm or 1/16" per graduation) by the depth pointer. Then tighten the screw to secure the stopper pole.
Now, your predetermined depth of cut can be obtained by loosening the lock lever and then lowering the tool body until the stopper pole makes contact with the adjusting hex bolt. CAUTION : Since excessive cutting may cause overload of the motor' or difficulty in controlling the a tool, the depth of cut should not be more than (5/8") t a pass when cutting grooves with a (1/4") diameter bit. [Note: When cutting grooves with an (3/4") diameter bit, the depth of cut should not be more than (1/4") a t a pass.] When you wish to cut grooves more than (5/8") deep with a (1/4") diameter bit or more than (1/4") deep with an (3/4") diameter bit, make several passes with progressively deeper bit settings.

Stopper block The stopper block has three adjusting hex bolts which raise or lower 0.8 mm (about 1/32") per turn. You can easily obtain three different depths of cut using these adjusting hex bolts without readjusting the stopper pole. Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of "Adjusting depth of cut". Adjust the two remaining hex bolts to obtain shallower depths f of cut. The differences in height o these hex bolts are equal to the differences in depths of cut. To adjust the hex bolts, first loosen the hex nuts on the hex bolts with the wrench and then turn the hex bolts. After obtaining the desired position, tighten the hex nuts while holding the hex bolts in the desired position. The stopper block is also convenient for making three passes with progressively deeper bit settings when cutting deep grooves.
Adjusting lock lever The locked position of the lock lever is adjustable. To adjust it, loosen the lock lever 3/4 turn and press the center of the lock lever. The hex nut will come out. Set the hex nut to the desired position and tighen the lock lever.
Switch action To start the tool, simply pull the trigger. Release the trigger to stop.

CAUTION:

Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Operation *Set the tool base on the workpiece to be cut without the bit making any contact. Then turn the tool on and wait until the bit attains full speed. Lower the tool body and move the tool forward over the workpiece surface, keeping the tool base flush and advancing smoothly until the cutting is complete. When doing edge cutting, the workpiece surface should be on the left side of the bit in the feed direction. (See the figure below)

Feed direction

///,'/!3it

revolving direction

(View from the top of the tool)
Correct bit feed direction
NOTE : Moving the tool forward too fast may cause a poor quality of cut, or damage to the bit or motor. Moving the tool forward too slowly may burn and mar the cut. The proper feed rate will depend on the bit size, the kind of workpiece and depth of cut. Before beginning the cut on the actual workpiece, it is advisable to make a sample cut on a piece of scrap lumber. This will show exactly how the cut will look as well as enable you to check dimensions.
*When using the straight guide, be sure to install it on the right side in the feed direction. This will help to keep it flush with the side of the workpiece.

Straight guide (optional accessory) The straight guide i s effectively used for straight cuts when chamfering or grooving.
To install the straight guide, insert the guide bars into the holes in the tool base. Adjust the distance between the bit and the straight guide. At the desired distance, tighten the wing bolts to secure the straight guide in place.
When cutting, move the tool with the straight guide flush with the side of the workpiece. If the distance (A) between the side of the workpiece and the cutting position is too wide for the straight guide, or if the side of the workpiece i s not straight, the straight guide cannot be used. In this case, firmly clamp a straight board to the workpiece and use it as a guide against the router base. Feed the tool in the direction of the arrow.
Templet guide (optional accessory) The templet guide provides a sleeve through which the bit passes, allowing use of the router with templet patterns.
To install the templet guide, loosen the screws on the tool base, insert the templet guide and then tighten the screws.

Base plate

Secure the templet to the workpiece. Place the tool on the templet and move the tool with the templet guide sliding along the side of the templet.
