SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, re and/or serious injury.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your mains-oper-
ated (corded) power tool or battery-operated (cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
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
1.
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. Unmodied plugs and
matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5.
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.
6. If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.
7. Use of power supply via an RCD with a rated resid-
ual current of 30 mA or less is always recommended.
8. Power tools can produce electromagnetic elds
(EMF) that are not harmful to the user. However,
users of pacemakers and other similar medical
devices should contact the maker of their device and/
or doctor for advice before operating this power tool.
9. Do not touch the power plug with wet hands.
10.
If the cord is damaged, have it replaced by the manu-
facturer or his agent in order to avoid a safety hazard.
Personal safety
1. 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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
3. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
4.
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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away
from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
8.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.

4ENGLISH
Power tool use and care
1. 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.
2. 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.
3. Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. 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.
5. Maintain power tools and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition that
may affect the power tool’s operation. If dam-
aged, have the power tool repaired before use.
Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing 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.
8. Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unexpected
situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Follow instruction for lubricating and chang-
ing accessories.
Recipro saw safety warnings
1. Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting accessory may contact hidden wir-
ing or its own cord. Cutting accessory contacting
a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
2. Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. Holding the workpiece 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 oor, workbench, etc.
7. Hold the tool rmly.
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 imme-
diately after operation; they may be extremely
hot and could burn your skin.
13. Do not operate the tool at no-load
unnecessarily.
14. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
16. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the workpiece. Otherwise, the
recipro saw blade may touch them, resulting an
electric shock, electrical leakage or gas leak.
SAVE THESE INSTRUCTIONS.
WARNING: DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
rules stated in this instruction manual may cause
serious personal injury.

OPERATION
CAUTION: Always hold the tool rmly with
one hand on insulation cover and the other on the
switch handle.
CAUTION: Always press the shoe rmly
against the workpiece during operation. If the
shoe is removed or held away from the workpiece
during operation, strong vibration and/or twisting will
be produced, causing the blade to snap dangerously.
CAUTION: Always wear gloves to protect
your hands from hot ying chips when cutting
metal.
CAUTION: Be sure to always wear suitable
eye protection which conforms with current
national standards.
CAUTION: Always use a suitable coolant
(cutting oil) when cutting metal. Failure to do so will
cause premature blade wear.
CAUTION: Do not quirk the blade during
cutting.
Press the shoe rmly against the workpiece. Do not allow
the tool to bounce. Bring the recipro saw blade into light
contact with the workpiece. First, make a pilot groove using
a slower speed. Then use a faster speed to continue cutting.
NOTICE: Do not cut the workpiece with the shoe
away from the workpiece or without the shoe.
Doing so increases the reaction force which may
break the recipro saw blade.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
