GENERAL SAFETY RULES GEA001-3
WARNING:
Read all instructions. Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
Work area safety
1. Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
2. Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while oper-
ating a power tool. Distractions can cause you to
lose control.
Electrical safety
4. 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.
5. 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.
6. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
7. 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.
8. 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.
Personal safety
9. 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.
10. Use safety equipment. Always wear eye protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju-
ries.
11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or plug-
ging in power tools that have the switch on invites
accidents.
12. 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.
13. Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
15. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
Power tool use and care
16. 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.
17. 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.
18. Disconnect the plug from the power source and/
or the battery pack 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.

4
19. Store idle power tools out of the reach of chil-
dren 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.
20. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused
by poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working con-
ditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
23. 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.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
GEB019-1
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to trimmer safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal injury.
1. Hold power tools by insulated gripping sur-
faces when performing an operation where the
cutting tool may contact hidden wiring or its
own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the
operator.
2. Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
3. Wear hearing protection during extended
period of operation.
4. Handle the bits very carefully.
5. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged
bit immediately.
6. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
7. Hold the tool firmly.
8. Keep hands away from rotating parts.
9. Make sure the bit is not contacting the work-
piece before the switch is turned on.
10. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or wob-
bling that could indicate improperly installed
bit.
11. Be careful of the bit rotating direction and the
feed direction.
12. Do not leave the tool running. Operate the tool
only when hand-held.
13. Always switch off and wait for the bit to come
to a complete stop before removing the tool
from workpiece.
14. Do not touch the bit immediately after opera-
tion; it may be extremely hot and could burn
your skin.
15. Do not smear the tool base carelessly with thin-
ner, gasoline, oil or the like. They may cause
cracks in the tool base.
16. Draw attention to the need to use cutters of the
correct shank diameter and which are suitable
for the speed of the tool.
17. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
18. Always use the correct dust mask/respirator for
the material and application you are working
with.
SAVE THESE INSTRUCTIONS.

ASSEMBLY CAUTION:
•Always be sure that the tool is switched off and unplugged before
carrying out any work on the tool.
Installing or removing trimmer bit
CAUTION:
•Do not tighten the collet nut without inserting a bit, or the collet cone will
break.
•Use only the wrenches provided with the tool.
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.
OPERATION Set the tool base on the workpiece to be cut without the bit making any con-
tact. Then turn the tool on and wait until the bit attains full speed. Move the tool
forward over the workpiece surface, keeping the tool base flush and advanc-
ing 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.
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 trimmer shoe, the straight guide or the trimmer guide, be
sure to keep it on the right side in the feed direction. This will help to
keep it flush with the side of the workpiece.
CAUTION:
•Since excessive cutting may cause overload of the motor or difficulty in
controlling the tool, the depth of cut should not be more than 3 mm at a
pass when cutting grooves. When you wish to cut grooves more than
3 mm deep, make several passes with progressively deeper bit settings.

Templet guide
The templet guide provides a sleeve through which the bit passes, allowing
use of the trimmer with templet patterns.
Loosen the screws and remove the base protector. Place the templet guide on
the base and replace the base protector. Then secure the base protector by
tightening the screws.
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.
NOTE:
•The workpiece will be cut a slightly different size from the templet. Allow
for the distance (X) between the router bit and the outside of the templet
guide. The distance (X) can be calculated by using the following
equation:
Distance (X) = (outside diameter of the templet guide - router bit diameter) / 2
Straight guide (Accessory)
The straight guide is effectively used for straight cuts when chamfering or
grooving.
