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
shock the operator.
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 saw blade
plain 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 work-
piece 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 kick-
back 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 correc-
tive 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
the saw blade is binding, it may walk up or kick-
back 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. Unsharp-
ened 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.
---------------------------------------------------
a) Do not operate the saw if lower safety guard
does not move freely and close instantly. Never
clamp or tie the bottom safety guard in an
opened position. If the saw is accidentally
dropped, lower safety guard may be bent. Raise
the lower safety guard with the retracting handle
(10) (fitted depending on the model) 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 safety
guard spring. If the safety guard and the spring
are not operating properly, they must be serv-
iced before use. Lower safety guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
c) Open the lower safety guard by hand only
when making special cuts, such as plunge cuts
and angle cuts. Raise lower safety guard by
retracting handle (10) (fitted depending on the
model) and as soon as blade enters the mate-
rial, the lower guard must be released. For all
other sawing, the lower safety guard must be
released.
d) Always observe that the lower safety 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.
Additional safety instructions for all saws with
riving knife:
a) Use the appropriate riving knife for the blade
being used. For the riving knife to work, it must be
thicker than the body of the blade but thinner than
the tooth set of the blade.
b) Adjust the riving knife as described in this
instruction manual. Incorrect spacing, posi-
tioning and alignment can make the riving knife
ineffective in preventing kickback.
c) Always use the riving knife except when
plunge cutting. Riving knife must be replaced
