General Safety Rules
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 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.
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 conditions will
reduce personal injuries.
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
plugging 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
balance 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

4
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.
19. 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.
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
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 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.
GEB016-1
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to jig saw safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.
1. Hold power tools by insulated gripping
surfaces 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. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT safety
glasses.
4. Avoid cutting nails. Inspect workpiece for any
nails and remove them before operation.
5. Do not cut oversize workpiece.
6. Check for the proper clearance beyond the
workpiece before cutting so that the blade will
not strike the floor, workbench, etc.
7. Hold the tool firmly.
8. Make sure the blade is not contacting the
workpiece before the switch is turned on.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Always switch off and wait for the blade to
come to a complete stop before removing the
blade from the workpiece.
12. Do not touch the blade or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
13. Do not operate the tool at no-load
unnecessarily.
14. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.
15. Always use the correct dust mask/respirator
for the material and application you are
working with.
