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
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 elec-
tric shock.

5. Avoid body contact with earthed or
grounded surfaces such as pipes, radia-
tors, 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 out-
door 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 con-
ditions will reduce personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plug-
ging 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 bet-
ter control of the power tool in unexpected sit-
uations.
14. Dress properly. Do not wear loose cloth-
ing 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 cor-
rect 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 adjust-
ments, changing accessories, or storing
power tools. Such preventive safety mea-
sures 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 unfa-
miliar with the power tool or these instruc-
tions to operate the power tool. Power
tools are dangerous in the hands of untrained
users.
20. Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age 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. Prop-
erly maintained cutting tools with sharp cut-

4
ting 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 instruc-
tions 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 quali-
fied 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 sur-
faces 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 opera-
tion.
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 unnec-
essarily.
14. Always use the correct dust mask/respira-
tor 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 mate-
rial supplier safety data.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the shoe
When the blade loses its cutting efficiency in one place along
its cutting edge, reposition the shoe to utilize a sharp, unused
portion of its cutting edge. This will help to lengthen the life of
the blade. To reposition the shoe, push the shoe button in the
“A”direction with a click and reposition as shown in the figure
which allows you to make five-way adjustment. To secure the
shoe, push the shoe button in the “B”direction with a click.
Switch action
CAUTION:
•Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
•Switch can be locked in “ON”position for ease of
operator comfort during extended use. Apply caution
when locking tool in “ON”position and maintain firm
grasp on tool.
To start the tool, simply pull the switch trigger. Tool speed is
increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch trig-
ger fully, then release it.

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 saw blade
CAUTION:
•Always clean out all chips or foreign matter adhering to
the blade, blade clamp and/or slider. Failure to do so
may cause insufficient tightening of the blade, resulting
in a serious injury.
To install the saw blade, always make sure that the blade
clamp sleeve is in released position before inserting the saw
blade. If the blade clamp sleeve is in fixed position, rotate the
blade clamp sleeve 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 sleeve 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 sleeve in
the direction of the arrow fully. The saw blade is removed and
the blade clamp sleeve is fixed at the released position.
NOTE:
•If you remove the saw blade without rotating the blade
clamp sleeve fully, the sleeve may not be locked of the
released positon. In this case, rotate the blade clamp
sleeve fully again, then make sure that the blade clamp
sleeve 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.
Press the shoe firmly against the workpiece. Do not allow the
tool to bounce. Bring the blade into light contact with the
workpiece. First, make a pilot groove using a slower speed.
Then use a faster speed to continue cutting.
MAINTENANCE CAUTION:
•Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only iden-
tical carbon brushes.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
•lead from lead-based paints,
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
