Always use blades with correct size
and shape (diamond vs. round) arbor
holes. Blades that do not match the
mounting hardware of the saw will run
eccentrically, causing loss of control.
CAUSES AND OPERATOR PREVENTION OF KICKBACK
12
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
13
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
14
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 operator.
Kickback is the result of tool misuse
15
and/or incorrect operating procedures
or conditions and can be avoided by
taking proper precautions as given
below:
• Maintain a firm grip with both hands on
the saw and position your body and arm
to allow you to resist KICKBACK forces.
Kickback forces can be controlled by the
operator, if proper precautions are taken.
• 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.
11
Never use damaged or incorrect
blade washers or bolts. The blade
washers and bolt were specially
designed for your saw, for optimum
performance and safety of operation.
Investigate and take corrective actions
to eliminate the cause of blade binding.
16
When restarting a saw in the work-
piece, center the saw blade in the kerf
and check that the 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 re-
started.
17
Support large panels to minimize the
risk of blade pinching and KICKBACK.
Large panels tend to sag under their own
weight. Support must be placed under the
panel on both sides, near the line of cut
and near the edge of the panel.
18
Do not use dull or damaged blade.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding, and KICKBACK.
Blade depth and bevel adjusting
19
locking levers must be tight and secure
before making cut. If blade adjustment
shifts while cutting, it may cause bind-
ing and KICKBACK.
20
Use extra caution when making a
"Pocket Cut" into existing walls or other
blind areas. The protruding blade may
cut objects that can cause KICKBACK.
