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

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.

2

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.

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.

SPECIFIC SAFETY RULES

GEB009-2

DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to recipro 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. Wear ear protectors.

3. Check the socket carefully for wear, cracks or
damage before installation.

4. Hold the tool firmly.

5. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.

6. The proper fastening torque may differ
depending upon the kind or size of the bolt.
Check the torque with a torque wrench.

NOTE:

• Hold the tool pointed straight at the bolt or nut.

• Excessive fastening torque may damage the bolt/

nut or socket. Before starting your job, always
perform a test operation to determine the proper
fastening time for your bolt or nut.

The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.

1. Vol ta ge

Voltage drop will cause a reduction in the fastening
torque.

2. Socket

• Failure to use the correct size socket will cause

a reduction in the fastening torque.

• A worn socket (wear on the hex end or square

end) will cause a reduction in the fastening
torque.

3. Bolt

• Even though the torque coefficient and the

class of bolt are the same, the proper fastening
torque will differ according to the diameter of
bolt.

• Even though the diameters of bolts are the

same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.

4. The use of the universal joint or the extension bar

somewhat reduces the fastening force of the impact
wrench. Compensate by fastening for a longer
period of time.

5

5. The manner of holding the tool or the material of

driving position to be fastened will affect the torque.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection
or maintenance.
