General Power Tool Safety Warnings

WARNING

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may

result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery operated (cordless) power tool.

1. Work area safety

a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2. Electrical safety

a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f. If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

3. Personal safety

a. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes,

General Power Tool Safety Warnings

jewelry or long hair can be caught in moving parts.

g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4. Power tool use and care

a. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
h. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Service

a. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety Warnings for Routers

Hold the power tool by insulated gripping surfaces only, because the cutter may contact its own cord. Cutting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by your hand or against the body leaves it unstable and may lead to loss of control.

SAVE THESE INSTRUCTIONS

Additional Safety Warnings

To reduce the risk of injury, always wear safety goggles or glasses with side shields. The operator and other people in the work area must wear eye protection in accordance with ANSI Z87.1. Eye protection does not fit all operators in the same way. Make sure the eye protection chosen has side shields or provides protection from flying debris both from the front and sides. The employer is responsible for enforcing the use of eye protection by the operator and other people in the work area. When required, wear head protection in accordance with ANSI Z89.1.

WARNING

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Entering the Workpiece

Always allow the router to reach the set speed before bringing the Router Bit 26 in contact with the Workpiece 38.

Feeding the Router

(Fig. 2, Fig. 19)

This section explains concepts of how to properly feed the plunge router while in operation.

As seen from the top of the plunge router, the Router Bit 26 turns clockwise and the cutting

edges of the Router Bit 26 are positioned to best cut into the Workpiece 38. Therefore, the most efficient cut is made by feeding the plunge router so that the Router Bit 26 turns into the Workpiece 38, not away. The following figure shows proper feed for various cuts. How fast you feed depends on the hardness of the material and the size of the cut. For some materials, it is best to make several cuts of increasing depth.

If the plunge router is hard to control, heats up, runs very slowly, or leaves an imperfect cut, consider these causes:

Operation

• Wrong direction of feed – hard to control.
• Feeding too fast – overloads motor.
• Dull bit – overloads motor.
• Cut is too large for one pass — overloads motor.
• Feeding too slow — leaves friction burns on workpiece.

Feed smoothly and steadily (do not force).

Practice and experience will help with familiarizing how the plunge router sounds and feels when it is working best.

Always hold the plunge router off the workpiece when turning the Trigger Switch 1 ON or OFF.

Contact the Workpiece 38 with the router after the plunge router has reached full speed, and remove it from the Workpiece 38 before turning the Trigger Switch 1 off. Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work.

Rate of Feed

(Fig. 19)

When routing or doing related work in wood and plastics, the best finishes will result if the depth of cut and feed rate are regulated to keep the motor operating at high speed. Feed the plunge router at a moderate rate. Soft materials require a faster feed rate than hard materials. The router may stall if improperly used or overloaded. Reduce the feed rate to prevent possible damage to the tool. Always be sure the Collet Nut 29 is tightened securely before use. Always use Router Bits 26 with the shortest cutting length necessary to produce the desired

Fig. 19 26 38

cut. This will minimize Router Bit 26 run-out and chatter. It may be necessary to make the cut in more than one pass with progressively deeper settings to avoid overloading the motor. If the Router Bit 26 cuts freely and the motor does not slow down, the cutting depth is generally correct.

Routing Tips

Always use Router Bits 26 with the shortest cutting length necessary to produce the desired cut. This will minimize Router Bit 26 chatter.

Always be sure the Collet Nut 29 is tightened securely before use.

Soft materials require a faster feed rate than hard materials.

The router may stall if improperly used or overloaded.

Reduce the feed rate to prevent possible damage to the tool.

To be certain that your depth and speed settings provide the desired results, test the settings by routing some scrap material before routing the actual workpiece.

If the router is hard to control, heats up, runs very slowly, or leaves an imperfect cut, consider these causes:

• Wrong direction of feed – hard to control.
• Feeding too fast – overloads motor.
• Dull bit – overloads motor.
• Cut is too large for one pass – overloads motor.
• Feeding too slow – leaves friction burns on work.

When routing deep cuts, it is best to make multiple progressively deeper cuts rather than trying to rout the full depth in one pass. The appropriate depth of cut will depend on the type of material and the type of cutter being used. The GOF13-25 and its multiple-step Depth Stop Turret 16 are ideally suited for multiple pass routing situations. (See “Setting Depth of Cut” on page 14.)

Operation

Exiting the Workpiece

For best control and results, always move the router so that the Router Bit 26 cutter exits from the workpiece before switching off the router.

Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work.

Guiding the Router

(Fig. 1)

The router can be guided through the workpiece in any of several ways. The method you use depends, of course, on the demands of the particular job and on convenience. For routing operations such as grooving or dadoing, it is often necessary to guide the tool in a line parallel to a straight edge. One method of obtaining a straight cut is to securely clamp a board or other straightedge to the work surface and guide the edge of the router Subbase 10 along this path.

For edge and profile routing without a parallel guide, the Router Bit 26 must be fitted with a pilot pin or a ball bearing. The lower portion of a pilot-tipped Router Bit 26 is a shaft with no cutting edges. Bearing guide Router Bits 26 have a ball bearing to pilot the Router Bit 26.

This pilot slides along the edge of the work as the rotating blades make the cut, forming molding or decorative edges. The edge on which the pilot slides should be perfectly smooth since any irregularities are transferred to the shaped surface. When routing a workpiece that requires edge forming on the endgrain, always rout the endgrain edge before routing the edges that follow the grain. This minimizes the possibility of damage from any blowout at the end of endgrain.

While it is switched ON, guide the router towards the workpiece from the side until the pilot pin or the ball bearing of the Router Bit 26 is touching the side of the workpiece edge that you want to machine.

Guide the router along the workpiece edge. Make sure that the router Base 8 is fully in contact with the workpiece surface, and the Router Bit 26 is perpendicular to the workpiece surface. Excess pressure can damage the edge of the workpiece.

Self-Piloted Bits

(Fig. 21)

Self-piloted Router Bits 26 have an integral round tip or ball bearing which rides against the work surface above or below the cutter to control horizontal cutting depth. When using these Router Bits 26, neither the roller guide nor the straight edge guide is required. When guiding against a laminated surface, use wax or other lubricant, and do not apply excess pressure or the piloted end may mar the work. Bearing pilots must be kept clean and free of

Operation

adhesive or other residue. Router Bits 26 bearings are sealed and permanently lubricated, and should be replaced when they no longer turn freely to avoid damaging the work surface.

Routing with the Edge Guide

(Fig. 22, Fig. 23)

To attach the Edge Guide 20 to the router Base 8:

1. Assemble the Edge Guide 20 according to the instructions in "Edge Guide Assembly" on page 13.

Fig. 22 21 21 8 13 20

Mechanical assembly diagram showing a motor mounted on a metal bracket with a downward arrow indicating motion (no text or symbols)

1. Slide the Edge Guide Rods 21 into the router Base 8. For maximum stability, make sure each Edge Guide Rod 21 goes through both holes and protrudes out the other side of the Base 8. (At a minimum, the Edge Guide Rods 21 must be inserted far enough into the router Base 8 that they are both supported from below at a point beyond the fastener on the router.)

2. Securely fasten the router Base 8 to the Edge Guide Rods 21 by tightening the Wing Bolt 13.

With the Edge Guide 20 installed and adjusted, the router should be fed normally, keeping the Edge Guide 20 in contact with the edge of the workpiece at all times.

Routing Curves

(Fig. 24, Fig. 25, Fig. 26)

1. Assemble the Centering Pin 25 onto the Edge Guide 20 according to the instructions in "Convert Edge Guide into Circle Guide" on page13.

2. Slide the Edge Guide Rods 21 into the Base 8. For maximum stability, make sure each rod goes through both holes and protrudes out the other side of the router base. (At a minimum, the rods must be inserted far enough into the router base that they are both supported from below at a point beyond the fastener on the router.)

3. Securely fasten the router Base 8 to the Edge Guide Rods 20 by tightening the Wing Bolts 13.

4. Push the Centering Pin 25 into the marked center point of the curve and carry out the routing process with a uniform feed.

Before using the Edge Guide 20 as a circle guide, always ensure the conical tip of the Centering Pin 25 is fully in the workpiece and securely anchors the Centering Pin 25 on the work surface. Confirm the Base 8 of the router is resting fully on the work surface before beginning routing operations.

Using Template Guides (optional accessory)

Follow the normal procedure for using the router.

• When a clean round opening in the workpiece is desired, the smoothest surface for the opening will be achieved by moving the router in a clockwise direction.
• When making a round workpiece such as a small tabletop, the smoothest surface for the round workpiece will be achieved by moving the router in a counter-clockwise direction.

Routing with a Template Guide

(Fig. 27)

Using the Template Guide 33, you can transfer contours from templates or patterns to the workpiece.

Select the Template Guide 33 that is suitable for the thickness of the template or pattern. Due to the protruding height of the Template Guide 33, the template must have a minimum thickness of 0.315" (8 mm).

Fig. 27 33 10

Maximum Bit/Cutter Size for Template Guides

When using a Template Guide 33, use only Router Bit 26 with cutters that are 1/16" less than the internal diameter of the template guide.

To rout with the Template Guide 33, proceed as follows:

Operation

1. Insert the Template Guide 33 according to the instructions in "Installing the Template Guide (optional accessory)" on page 12.
2. Switch the power tool on and move it with the Template Guide 33 towards the template.
3. Push the Plunge Lock Lever 6 down and slowly move the router down until it reaches the set routing depth. Release

the Plunge Lock Lever 6 again to lock this depth. If necessary, push the Plunge Lock Lever 6 up to fully lock it.

1. Move the power tool with the protruding Template Guide 33 along the template, applying pressure to the sides.
