g) Always use blades with correct size and shape (diamond
versus round) of arbor 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 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 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 cut" 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.
