General Power Tool Safety Warnings

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 counterclockwise.

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 1-1/8". Using cutter larger than 1-1/8" 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 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.

Additional Safety Warnings

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.

Operation

Feeding the Trim Router

(Fig. 13)

This section explains concepts of how to properly feed the trim 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 trim 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 trim 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 trim router is hard to control, heats up, runs very slowly or leaves an imperfect cut, consider these causes:

Fig. 13 workpiece direction of router feed

• 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 trim router sounds and feels when it is working best.

Guiding the Trim Router

(Fig. 14)

The trimmer 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 grooves or dados, 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.

Always hold the trim router off the workpiece when turning the switch ON or OFF. Contact the workpiece with the router after the trim 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.

Operation

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 trim 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

Straight Edge Guide

(Fig. 16)

The Straight Edge Guide 20 can be used to guide the trim 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.

ATTACHING THE EDGE GUIDE

Attach the Straight Edge Guide 20 to the Fixed Base 13 using the Rear Accessory Thumb Screw 17 and washer (Fig. 16).

OPERATING INSTRUCTIONS

- With the guide installed and adjusted, the trimmer should be fed normally, keeping the guide in contact with the edge of the workpiece at all times.

Self-Piloted Bits (sold separately)

(Fig. 17)

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.

The optional Fixed Base Roller/Bushing Guide 21 is used when edge-forming or trimming with unpiloted/non-bearing bits.

Attachment of Roller/Bushing Guide

Attach the Roller/Bushing Guide 21 using the Rear Accessory Thumb Screw 17 and washer.

Adjustment of Roller/Bushing Guide

Vertical Adjustment:

1. Loosen the Rear Accessory Thumb Screw 17 and adjust up or down as necessary to allow roller/bushing 24 to ride on the intended guiding surface.
2. Tighten wing screw.

Horizontal Adjustment:

Whether making straight or bevel cuts, the width of material removed is determined by the distance between the front of the router bit's cutter and the front of the roller/bushing.

Adjust the front of the roller/bushing as follows:

1. Loosen Wing Nut 25 at the bottom.
2. Rotate the Wing Nut 26 on the back of the guide to move the roller/bushing in or out to create the amount of cutter exposure needed to trim the laminate flush with the guiding surface or to create the desired bevel.
3. Be sure the bit clears the top of the roller/bushing guide by at least 1/8" (3 mm) to avoid damage.
4. Tighten Wing Nut 25 on the bottom of the guide assembly.
5. Make a trial cut to check the setting and re-adjust as necessary.

Use of the Roller/Bushing Guide

1. 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.
2. To maintain a consistent width of cut, a consistent angle must be maintained between the router and the workpiece.

Maintenance

WARNING

To avoid accidents, always disconnect the battery pack from the tool before cleaning or performing any maintenance.

WARNING

Never immerse your tool, battery pack, or charger in liquid, or allow liquid to flow inside them.

General maintenance

Keep your trim router, accessories, battery pack and charger in good working order by adopting a regular maintenance program. Inspect your trim router for issues such as undue noise, binding of moving parts, breakage of parts, or any other condition that may affect trim router operation.

If the trim router does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the trim router still does not work properly, return the trim router, charger and battery pack to a BOSCH service facility for repairs.

Service

WARNING

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.

Cleaning

Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Periodically remove dust from the tool by wiping with a clean rag or using compressed air on the inside of the base and motor unit as well as the fine depth adjustment system.

Remove dust and debris from all vents. Keep the trim router clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean the trim router, since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around tools.

Storage and Maintenance

Store trim router and accessories in a cool dry place and avoid freezing. Before use, check router bits for cracks and fractures, do not use if damage is suspected.
