General Power Tool Safety
Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions 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.
Work area safety
1. Keep work area clean and well lit. Cluttered or
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 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
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 outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

3
9. If operating a power tool in a damp location is
unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
recommended.
Personal safety
11. 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.
12. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
13. 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 energising power tools
that have the switch on invites accidents.
14. 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.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. 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.
17. 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.
Power tool use and care
18. 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.
19. 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.
20. 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.
21. 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.
22. Maintain power tools. 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.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. 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.
Service
25. 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.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and
grease.
GEB018-3
ROUTER SAFETY WARNINGS
1. Hold power tool by insulated gripping
surfaces, because the cutter may contact its
own cord. Cutting a "live" wire may make
exposed metal parts of the power 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 your hand or against the 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 with both hands.
8. Keep hands away from rotating parts.

4
9. Make sure the bit is not contacting the
workpiece 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
wobbling 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
operation; it may be extremely hot and could
burn your skin.
15. Do not smear the tool base carelessly with
thinner, 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
inhalation 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.

005052
Place the tool on a flat surface. Loosen the lock lever and
lower the tool body until the bit just touches the flat
surface. Press the lock lever down to lock the tool body.
Now lower the stopper pole until it makes contact with the
stopper block. The stopper pole can be moved rapidly by
depressing the fast-feed button. Raise the stopper pole
until the desired depth of cut is obtained. The depth of cut
is equal to the distance between the stopper pole and the
stopper block. Stopper pole travel can be checked with
the scale (1 mm per graduation) on the tool body. Minute
depth adjustments can be obtained by turning the
stopper pole (1.5 mm per turn).
The stopper block has the adjusting hex bolts which
move 1 mm per turn. They are convenient for making
stepped cuts. To adjust the hex bolts, first loosen the hex
nuts on the hex bolts with the wrench and then turn the
hex bolts. After obtaining the desired position, tighten the
hex nuts.
Nylon nut

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 15 mm at a pass when
cutting grooves. When you wish to cut grooves
more than 15 mm deep, make several passes with
progressively deeper bit settings.
• Do not lower the nylon nut too low, or the bit will
protrude dangerously.
• Before operating the tool, check to be sure that the
tool automatically rises to the upper limit.
Switch action
1
005054
CAUTION:
• Make sure that the shaft lock is released before the
switch is turned on.
To start the tool, move the switch lever to the I (ON)
position. To stop the tool, move the switch lever to the O
(OFF) position.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the bit
12
005055
CAUTION:
• Install the bit securely. Always use only the wrench
provided with the tool. A loose or overtightened bit
can be dangerous.
• Do not tighten the collet nut without inserting a bit or
install smaller shank bits without using a collet
sleeve. Either can lead to breakage of the collet
cone.
Insert the bit all the way into the collet cone and withdraw
it very slightly (approx. 2 mm). Press the shaft lock to
keep the shaft stationary and use the wrench to tighten
the collet nut securely. When using router bits with
smaller shank diameter, first insert the appropriate collet
sleeve into the collet cone, then install the bit as
described above.
To remove the bit, follow the installation procedure in
reverse.
OPERATION
CAUTION:
• Before operation, always make sure that the tool
body automatically rises to the upper limit and the
bit does not protrude from the tool base when the
lock lever is loosened.
• Before operation, always make sure that the chip
deflector is installed properly.
Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Lower the tool body and
move the tool forward over the workpiece surface,
keeping the tool base flush and advancing 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 straight guide or the trimmer guide,
be sure to install it on the right side in the feed
direction. This will help to keep it flush with the side
of the workpiece.
