GENERAL SAFETY RULES GEA001-2
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
atmospheres, 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
operating 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 elec-
tric shock.
5. Avoid body contact with earthed or
grounded surfaces such as pipes, radia-
tors, 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
conditions. 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 out-
door 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
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate con-
ditions will reduce personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plug-
ging in. Carrying power tools with your finger
on the switch or plugging in power tools that
have the switch on invites accidents.

4
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 balance at all times. This enables bet-
ter control of the power tool in unexpected sit-
uations.
14. Dress properly. Do not wear loose cloth-
ing 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 cor-
rect 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 adjust-
ments, changing accessories, or storing
power tools. Such preventive safety mea-
sures reduce the risk of starting the power
tool accidentally.
19. Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these instruc-
tions to operate the power tool. Power
tools are dangerous in the hands of untrained
users.
20. Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age 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. Prop-
erly maintained cutting tools with sharp cut-
ting 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 instruc-
tions and in the manner intended for the
particular type of power tool, 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.
Service
23. Have your power tool serviced by a quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
ADDITIONAL SAFETY RULES ENB054-1
1. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live”wire will make exposed metal parts
of the tool “live”and shock the operator.
2. Wear hearing protection during extended period
of operation.
3. Handle the bits very carefully.
4. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged
bit immediately.
5. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
6. Hold the tool firmly.
7. Keep hands away from rotating parts.

5
8. Make sure the bit is not contacting the work-
piece before the switch is turned on.
9. 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.
10. Be careful of the bit rotating direction and the
feed direction.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Always switch off and wait for the bit to come to
a complete stop before removing the tool from
workpiece.
13. Do not touch the bit immediately after operation;
it may be extremely hot and could burn your
skin.
14. Always lead the power supply cord away from
the tool towards the rear.
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.

OPERATION
Turn the tool on without the bit making any contact with the workpiece and wait
until the bit attains full speed. Then move the tool over the workpiece surface,
keeping the tool base and trimmer shoe flush with the sides of the workpiece.
NOTE:
•This tool can be used as a conventional trimmer when you remove the
trimmer shoe.
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.

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
