3 Hold 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 tool
live and shock the operator.
4 When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and reduces
the chance for blade binding.
5 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.
6 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.
7 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 operator.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
8 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.
9 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.
10 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.
11 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.
12 Do not use dull or damaged blade. Unsharpened or
improperly set blades produce narrow kerf causing excessive
friction, blade binding and KICKBACK.
13 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.
14 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.
15 Never disable the blade guard. The blade guard
provides protection from serious bodily injury - it cannot be
fully effective if tampered with.
