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.
ADDITIONAL SAFETY RULES ENB050-2
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 eye protection and dust mask.
3. Ventilate your work area adequately.
4. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged
bit immediately.
5. Check for the proper clearance beneath the
workpiece before cutting so that the bit will not
strike a hard surface such as the floor, work-
bench, etc.
6. Do not cut metal objects such as nails and
screws. Inspect for and remove all nails, screws
and other foreign material from the workpiece
before operation.
7. Check that the bit is not contacting the work-
piece before the switch is turned on. Always
hold the tool with two hands while switching the
tool on. The motor torque can cause the tool to
turn.
8. 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.
9. Make sure that the shaft lock is released before
the switch is turned on.
10. Always use with the shoe securely attached to
the tool and positioned flat and firmly against
the workpiece.
11. Hold the tool firmly.
12. Do not perform any operation using your hands
to support or guide the workpiece.
13. Keep hands away from moving parts.
14. Do not use this tool for drilling.
15. Do not leave the tool running. Operate the tool
only when hand-held.
16. Always switch off and wait for the bit to come to
a complete stop before removing the bit from
workpiece.
17. Do not touch the bit or the workpiece immedi-
ately after operation; it may be extremely hot
and could burn your skin.
18. Always lead the power supply cord away from
the tool towards the rear.
19. Draw attention to the need to use cutters of the
correct shank diameter and which are suitable
for the speed of the tool.

NOTE:
1. When using this tool, the rotating action causes the tool to pull. The less
pressure applied to the tool causes less pull and provides a more accu-
rate cut. Excessive pressure or fast cutting can cause the bit to dull or
break premature.
2. When cutting drywall around outlet boxes, cut in a counterclockwise
direction for ease of cut.
3. The standard bit included with this tool is for cutting drywall only. When
cutting materials other than drywall, do not use the standard drywall
guide bit.
