GENERAL SAFETY RULES GEA001-1
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.
- WARNING- To reduce the risk of injury, user must read instruction manual.
ADDITIONAL SAFETY RULES FOR TOOL GEB008-1
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 tool 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 work-
piece 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 immedi-
ately after operation; they may be extremely hot
and could burn your skin.
13. Do not operate the tool at no-load unnecessar-
ily.
14. Always use the correct dust mask/respirator for
the material and application you are working
with.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

To install the saw blade, always make sure that the blade clamp lever is in
released position on the insulation cover before inserting the saw blade. If
the blade clamp lever is in fixed position, rotate the blade clamp lever in the
direction of the arrow so that it can be locked at the released positon .
Insert the saw blade into the blade clamp as far as it will go. The blade clamp
lever rotates and the saw blade is fixed. Make sure that the saw blade cannot
be extracted even though you try to pull it out.
NOTE:
•If you do not insert the saw blade deep enough, the saw blade may be
ejected unexpectedly during operation. This can be extremely
dangerous.
To remove the saw blade, rotate the blade clamp lever in the direction of the
arrow fully. The saw blade is removed and the blade clamp lever is fixed at the
released position .
NOTE:
•If you remove the saw blade without rotating the blade clamp lever fully,
the lever may not be locked in the released positon . In this case,
rotate the blade clamp lever fully again, then make sure that the blade
clamp lever locked at the released position .
OPERATION CAUTION:
•Always press the shoe firmly against the workpiece during operation. If
the shoe is held away from the workpiece during operation, strong
vibration and/or twisting will be produced, causing the blade to snap
dangerously.
•Always wear gloves to protect your hands from hot flying chips when
cutting metal.
•Be sure to always wear suitable eye protection which conforms with
current national standards.
•Always use a suitable coolant (cutting oil) when cutting metal. Failure to
do so will cause premature blade wear.
