GENERAL SAFETY RULES

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

1) Work area
a) Keep work area clean and well lit.

Cluttered and 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 of 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

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 safety equipment. Always wear eye protection.

Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in

the off position before plugging in.

Carrying power tools with your finger on the
switch or plugging in 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 rotating part
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 these devices 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 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
tools 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 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
intended could result in a hazardous situation.

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.

PRECAUTION

Keep children and infirm persons away.
When not in use, tools should be stored out of
reach of children and infirm persons.

SAFETY INSTRUCTIONS FOR ALL SAWS

DANGER:

a) Keep hands away from cutting area and the 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.

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.

䡬 Never use any abrasive wheels

Burst of abrasive wheel cause serious injury of
operator or persons around the working area.

FURTHER SAFETY INSTRUCTIONS FOR ALL
SAWS

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 wood 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.

5

Position your body 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 cut”

into existing walls or other blind areas.

The protruding blade may cut objects that can
cause kickback.

SAFETY INSTRUCTIONS FOR SAWS WITH
INNER PENDULUM GUARD

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 depth 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 build-up of
debris.

c) Lower guard should be retracted manually only

for special cuts such as “plunge cuts” and
“compound cuts”. Raise lower guard by retracting
handle and as soon as blade enters the material,
the lower guard must be released.

For all other sawing, the lower guard should
operate automatically.

d) Always observe that the lower guard is covering

the blade before placing saw down on bench or floor.

An unprotected, coasting blade will cause the saw
to walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to
stop after switch is released.
