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.

⅜ 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.

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.
