a stable platform. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
e) Hold the power tool by insulated gripping
surfaces only, 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 could
give the operator an electric shock.
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.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
SAWS
Kickback causes and related warnings
- 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 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,
center 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 sawing 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
Lower Guard Function
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.
c) Lower guard may 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.
