Read all safety
warnings and instructions.Failure to
follow the warnings and instructions
may result in electric shock, fire and / or
serious injury.
Save all warnings and instructions for
future reference.
The term power tool in the warnings
refers to your mains-operated (corded)
power tool or battery-operated
(cordless) power tool.
WARNING: Risk of fire and
electric shock. Dry location use only.
Do not expose to rain. Risk of injury.
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 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
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.
Unmodified 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 electric shock
if your body is earthed or grounded.
3. Do not expose power tools to rain or
wet conditions. 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 the 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 unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric
Personal safety
1. Stay alert, watch what you are doing
and use common sense when operating a
power tool. Do not use the tool while tired
or under the influence of drugs, alcohol, or
medication. 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
that 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 finger on the
switch or energizing power tools that have
the switch on invites accidents.
Page 4
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 jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure that these are
connected and properly used. Use of these
devices can reduce dust-related hazards.
5. Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, 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,
tool bits etc., in accordance with these
instructions, 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.
power tools
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 more safely 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 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. 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.
1. Recharge only with the charger
specified by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of fire when used with
another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury
and fire.
3. When the battery pack is not in use,
keep it away from other metal objects,
such as paper clips, coins, keys, nails,
screws or other small metal objects that
can make a connection from one terminal
to another. Shorting the battery terminals
together may cause burns or a fire.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, also seek
medical help. Liquid ejected from the battery
Page 5
may cause irritation or burns.
1. 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.
1. Use battery only with charger listed.
Battery pack
Keep hands away
from cutting area and blade. Keep your
second hand on the auxiliary handle or
motor housing. If both hands are holding
the saw, the blade cannot cut them.
1. Hold tool by insulated gripping surfaces
(handles) when performing an operation
where the cutting tool may contact hidden
wiring or its own cord. Contact with a “live”
wire will make the exposed metal parts of
the tool “live” and shock the operator.
2. Cutting workpieces covered with
oil can cause the blade to come off
unexpectedly. Wipe off all excess oil from
workpieces before cutting.
3. Keep your body positioned to either
side of the saw blade, but not in line with
the saw blade.
4. Do not touch the blade or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
5. Do not cut an oversized workpiece.
6. Check for the proper clearance under
the workpiece before cutting so that the
blade will not strike the workbench or
material under the workpiece.
7. Make sure the blade is not contacting
the workpiece before reaching full speed.
8. Secure material before cutting. Never
hold a workpiece in your hand or legs. Small
or thin material may flex or vibrate with the
blade, causing loss of control.
9. Never reach into the cutting path of the
Blades coast after saw
is switched off.

It has been found that electric tools are
subject to accelerated wear and possible
premature failure when they are used
to work on fiber glass boats and sports
cars, wallboard, spackling compounds or
plaster. The chips and grindings from
these materials are highly abrasive to
electrical tool parts, such as bearings,
brushes, commutators, etc. Consequently,
it is not recommended that this tool be
used for extended work on any fiberglass
material, wallboard, spackling compound
or plaster. During any use on these
materials, it is extremely important that the
tool is cleaned frequently by blowing with an
air jet.
WARNING: Do not at any time
let brake fluid, gasoline, petroleum-based
products, penetrating oils, etc. come in
contact with plastic parts. Chemicals can
damage, weaken or destroy plastic, which
may result in serious personal injury.
Periodic maintenance allows for long life
and trouble-free operation. A cleaning and
maintenance schedule should be maintained.
As a common preventive maintenance
practice, follow these recommended steps:
1. W
hen work has been completed, clean the
tool to allow smooth functioning of the tool
over time.
2. U
se clean damp cloths to wipe the tool.
3. C
heck the state of all electrical cables.
4. Keep the motor air openings free from
oil, grease and sawdust or woodchips,
and store tool in a dry place.
5. Be certain that all moving parts are
lengthy exposure to damp and/or
dirty conditions.
