WARNING! Read all safety warnings and all instructions Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INST RUCTIONS
FOR FUTURE REFERENCE
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2) ELECTRICAL SAFETY
a) 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.

b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) 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.
e) 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.
f) 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.
3) PERSONAL SAFETY
a) 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.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) 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 finger on the switch or energising power tools that have the switch on invites
accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key
left attached to a rotatingpart of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control
of the power tool in unexpected situations.
f) 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.
g) 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.
4) POWER TOOL USE AND CARE
a) 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.
b) 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.
c) Disconnect the plug from the power source and/or the battery pack from 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) 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.
h) Caution! The dust collect cover is very hot when cutting or after cutting.
Don’t touch it by hand!!
5) SERVICE
a) 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.
Safety Instructions for Saw
DANGER:
a) Keep hands away from cutting area and the blade. Keep your second hand on auxiliary
handle .If both hands are holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade below
the workpiece.
c) 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.
d) 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.
e) 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 also
make exposed metal parts of the power tool "live" and shock the operator.
f) When ripping always use a rip fence or straight edge guide. This improves the accuracy of
cut and reduces the chance of blade binding.
g) Always use blades with correct size and shape (diamond versus round) of arbour holes.
Blades that do not match the mounting hardware of the saw will run eccentrically,causing loss
of control.
h) Never use damaged or incorrect blade washers or bolt.The blade washers and bolt were
specially designed for your saw, for optimum performance and safety of operation.

Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an
uncontrolled 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.
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 metal causing the blade to climb out of the kerf and jump back
toward the 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:
a) 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.
b) 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.
c) When restarting a saw in the workpiece, centre the saw blade in the kerf and check that
saw teeth are not engaged into the material. If saw blade is binding, it may walk up or
kickback from the workpiece as the saw is restarted.
d) 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.
e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure before making
cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
g) Use extra caution when making a “plunge cuts” into existing walls or other blind
areas.The protruding blade may cut objects that can cause kickback
Lower Guard Safety Instructions
a) Check lower guard for proper closing before each use. Do not operate the saw if lower
guard does not move freely and close instantly. 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.
b) Check the operation 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 build-up of debris.
