GENERAL POWER TOOL SAFETY WARNINGS
WORK AREA SAFETY
ELECTRICAL SAFETY
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• 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.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
• 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.
• 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.
• Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
• 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.
• 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.
• If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
• 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.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• 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.
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, re 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.
POWER TOOL USE AND CARE
• 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.
• 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.
• 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.
• 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.
• 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.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the power tool, accessories and 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.
• 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 medi-
cation. A moment of inattention while operating
power tools may result in serious personal injury.
• Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
• 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.
SPECIFIC SAFETY RULES
BATTERY TOOL USE AND CARE
• Use power tools only with speci cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.
• Under abusive conditions, liquid may be eject-
ed from the battery, avoid contact. If contact
accidentally occurs, ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
SERVICE
• 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.
If the blade becomes twisted or misaligned in
the cut, the teeth at the back edge of the blade
can dig into the top surface of the wood causing
the blade to climb out of the kerf and jump back
toward operator.
KICKBACK is the result of saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
• Maintain a firm grip with both hands on
the saw and position your arms to resist
KICKBACK forces. Position your body to
either side of the blade, but not in line with
the blade. KICKBACK could cause the saw to
jump backwards, but kickback forces can be
controlled by the operator, if proper precautions
are taken.
• When blade is binding, or when interrupting
a cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the saw from the work or
pull the saw backward while the blade is in
motion or KICKBACK may occur. Investigate
and take corrective actions to eliminate the
cause of blade binding.
• When restarting a saw in the workpiece,
center the saw blade in the kerf and check
that saw teeth are not engaged into the mate-
rial. If saw blade is binding, it may walk up or
KICKBACK from the workpiece as the saw is
restarted.
• Support large panels to minimize the risk of
blade pinching and KICKBACK. Large panels
tend to sag under their own weight. Supports
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.
• Do not use dull or damaged blade. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding
and KICKBACK.
• Blade depth and bevel adjusting locking
levers must be tight and secure before mak-
ing cut. If blade adjustment shifts while cutting,
it may cause binding and KICKBACK.
• Use extra caution when making a "Plunge
Cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause KICKBACK.
• Check lower guard for proper closing before
each use. Do not operate the saw if lower
guard does not move freely and close in-
stantly. Never clamp or tie the lower guard into
the open position. If saw is accidentally dropped,
lower guard may be bent. Raise the lower guard
with the retracting handle and make sure it moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
• Check the operation and condition of the lower
guard spring. If the guard and the spring are
not operating properly, they must be serviced
before use. Lower guard may operate sluggishly
due to damaged parts, gummy deposits, or a
buildup of debris.
DANGER:
• Keep hands away from cutting area and blade.
Keep your second hand on auxiliary handle
or motor housing. If both hands are holding the
saw, they cannot be cut by the blade.
• Do not reach underneath the workpiece. The
guard cannot protect you from the blade below
the workpiece.
• Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
• NEVER hold piece being cut in your hands
or across your leg. Secure the workpiece to
a stable platform. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
• 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 also
make exposed metal parts of the power tool live
and shock the operator.
• When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut
and reduces the chance of blade binding.
• Always use blades with correct size and shape
(diamond vs. round) arbor holes. Blades that
do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
• Never use damaged or incorrect blade wash-
ers or bolts. The blade washers and bolts were
specially designed for your saw, for optimum
performance and safety of operation.
Causes and Operator Prevention of KICK-
BACK:
KICKBACK is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an un-
controlled saw to lift up and out of the workpiece
toward the operator.
When the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator.
• Recharge only with the charger speci ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
