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 hati 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, jewelry or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection

General Power Tool Safety Warnings

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. Battery tool use and care

a. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

b. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

c. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

d. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

e. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

f. Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F (130°C) may cause explosion.

g. Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

General Power Tool Safety Warnings

6. 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.

b. Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Instructions for Cordless Routers

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.

Additional Safety Warnings

If cutting into existing walls or other blind areas where electrical wiring may exist is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Always make sure the work surface is free from nails and other foreign objects. Cutting into a nail can cause the bit and the tool to jump and damage the bit.

Never hold the workpiece in one hand and the tool in the other hand when in use.

Never place hands near or below cutting surface. Clamping the material and guiding the tool with both hands is safer.

Never lay workpiece on top of hard surfaces, like concrete, stone, etc. Protruding cutting bit may cause tool to jump.

Always wear safety goggles and dust mask. Use only in well ventilated area. Using personal safety devices and working in safe environment reduces risk of injury.

After changing the bits or making any adjustments, make sure the collet nut and any other adjustment devices are securely tightened. Loose adjustment device can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.

Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the material causing loss of control of the cutter.

The direction of feeding the bit into the material is very important and it relates to the direction of bit rotation. When viewing the tool from the top, the bit rotates clockwise. Feed direction of cutting must be counter-clockwise.

NOTE: Inside and outside cuts will require different feed direction, refer to section on feeding the router. Feeding the tool in the wrong direction, causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed.

Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can snap during use. Dull bits require more force to push the tool, possibly causing the bit to break.

Never touch the bit during or immediately after the use. After use the bit is too hot to be touched by bare hands.

Never lay the tool down until the motor has come to a complete standstill. The spinning bit can grab the surface and pull the tool out of your control.

Do not use Cutter diameter larger than 1-1/2". Using cutter larger than 1-1/2" may result in personal injury.

Use only router bits that have shank diameters that match the installed collet. Using a router bit that has a smaller shank could

Additional Safety Warnings

cause the bit to come loose during operation and become a projectile.

Never operate router bits at speeds that are higher than their maximum rated speed. Router bits running faster than their rated speed can break and fly apart.

GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.

Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

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.

Feeding the Palm Router

(Fig. 33)

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

Make sure to read the corresponding sections for detailed operational steps for each base type.

As seen from the top of the palm router, the bit turns clockwise and the bit's cutting edges are positioned to best cut into the workpiece. Therefore, the most efficient cut is made by feeding the palm router so that the bit turns into the workpiece, 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 palm 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 workpiece.

Feed smoothly and steadily (do not force).

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

Always hold the palm router off the workpiece when turning the switch on or off.

Fig. 33 workpiece direction of router feed

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

The Constant Electronic Control feature allows motor speed to be matched to cutter size and material hardness for improved finish, extended bit life, and higher performance.

Rate of Feed

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 palm 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 is tightened securely before use. Always use router bits with the shortest cutting length necessary to produce the desired cut. This will minimize router bit 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 bit cuts freely and the motor does not slow down, the cutting depth is generally correct.

Operation

Guiding the Palm Router

(Fig. 34)

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 sub-base along this path.

Straight Edge Guide (PR102) (optional accessory)

(Fig. 36)

The Straight Edge Guide 27 is an optional accessory that will guide the palm router parallel to a straight edge.

The guide features a scale for accurately positioning the edge guide relative to the bit. With the guide installed and adjusted, the router should be fed normally, keeping the guide in contact with the edge of the workpiece at all times.

The router guide can also be positioned directly under the router base for operations where a cut is needed close to or at the edge of the work, such as when rounding off deck planks. For complete instructions on installation and operation, please refer to the instructions included with this accessory.

Fig. 36 27

Self-Piloted Bits

(Fig. 37)

Self-piloted bits 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 bits, neither the roller guide or 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 adhesive or other residue. Router bit bearings are sealed and permanently lubricated, and should be replaced when they no longer turn freely to avoid damaging the work surface.

Fixed Base Roller/Bushing Guide (PR003) (optional accessory)

(Fig. 38)

The optional Fixed Base Roller/Bushing Guide 28 is used when edge-forming or trimming with unpiloted/non-bearing bits.

With the fixed Base roller/bushing guide installed and adjusted, the router should be fed normally, keeping the guide in contact with the edge of the workpiece at all times.

To maintain a consistent width of cut, a consistent angle must be maintained between the router and the workpiece.

Using the Palm Router with Offset Base (PR004)

(Fig. 39, Fig. 40)

WARNING To reduce the risk of injury, do not use the off-

set base for more than 10 minutes continuously. Prolonged continuous use will result in the tool becoming hot to the touch.

The offset base is designed for routing in confined areas, especially for trimming laminates in areas that are inaccessible with the standard fixed base, such as locations that are close to adjacent vertical surfaces like as the tops of already-installed counter backsplash backsplashes.

The offset base allows routing extremely close to vertical surface in front of the

Fig. 39 2 29

Fig. 40 2 29

Operation

tool, as close as 1/2" when 3/4" bit is used (Removal of the black offset spindle cover further reduces distance from 3/4" bit and vertical surface to 3/8".) The 1-1/16" base opening makes it possible to use bits that have cutters as wide 13/16".

The offset base can also be used to scribe the back of a new counter backsplash so that it will mate precisely with the wall against which it will rest.

The nature of a belt drive mechanism, like the one in the offset base, is different than a typical palm router base. To help minimize heat build-up, the offset base has been designed with large bearings, specially-designed heat sinks, carefully-directed airflow and plastic heat shields. Depending on the application, the offset base can be used for up to about 10 minutes continuously before it will need to be left idle so that it can cool off.

The principles of using the offset base are basically the same as for the fixed base router setup (palm router in fixed base assembly, see “Using the Palm Router with Fixed Base” on page 31, with the following differences:

• Grip the Offset Base 29 with one hand using Palm Router Grip Area 2 and the other hand gripping the back of the base housing or the top of the offset spindle.
• For routing backsplashes and other elevated workpieces, some installers mount the offset base to a wood block that matches the height of the laminated backsplash. This helps to maintain a consistent angle between the bit's cutter and the workpiece; this also provides addition stability.

Note: Cutting with an offset base does not require changes in depth.

Offset Base Roller/Bushing Guide (optional accessory)

(Fig. 41)

The offset base roller/bushing guide is required when edge-forming or trimming with unpiloted non-bearing bits.

1. Install the Offset Base Roller/Bushing Guide 54 to the Offset Base 29 and adjust it as needed, see section "Attaching the Offset Base Roller/Bushing Guide" on page 17 and "Adjusting the Offset Base Roller/Bushing Guide" on page 18.
2. The router should be fed normally, keeping the guide in contact with the edge of the workpiece at all times. See “Feeding the Palm Router” on page 30.
3. To maintain a consistent width of cut, a consistent angle must be maintained between the router and the workpiece.

Fig. 41 29 54

Using the Palm Router with Tilt Base (PR005)

(Fig. 42, Fig. 43)

WARNING

To reduce the risk of in- jury, never grip the base directly above or next to the exposed bit.

The principles of using the tilt base are basically the same as for the fixed base router set-up. See "Using the Palm Router with Fixed Base" on page 31 with the following differences:

• A palm router in a Tilt Base 31 should always be used with a self-piloted or bearing bit.
• The cutting angle must be adjusted. See "Adjusting the Angle of the Tilt Base" on page 19.
  • Always grip the Palm Router 1 firmly using the Palm Router Grip Area 2. The proper grip position will depend on the angle of the cut.
• Feed the Palm Router 1 into the workpiece. See "Feeding the Palm Router" on page 30. When trimming edges while the bit is tilted toward the direction of feed, it is extremely important to keep the base square with the surface to be routed. If the tilt router is shifted in the direction of the surface it is riding on, the upper part of the cutter can dig far into the workpiece.
