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.
5.2.2 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 incor-
rect 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 minimise 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.
5.2.3 Lower guard function
a) Check guard for proper closing before each use.
Do not operate the saw if guard does not move
freely and enclose the blade instantly. Never
clamp or tie the guard so that the blade is
exposed. If saw is accidentally dropped, guard
may be bent. Check to make sure that guard
moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
b) Check the operation and condition of the guard
return spring. If the guard and the spring are
not operating properly, they must be serviced
before use. Guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
c) Assure that the base plate of the saw will not
shift while performing the “plunge cut” when
the blade bevel setting is not at 90°. Blade
shifting sideways will cause binding and likely
kick back.
d) Always observe that the 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.
