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 off-centre, 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.
(3.2) [Kickback causes and
related warnings]
Kickback is a sudden reaction to a pinched, jammed
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 jammed 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.
(3.3)
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 so that the saw teeth are
not engaged into the material. If a saw blade binds,
it may walk up or kickback from the workpiece as the
saw is restarted.
d) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
e) Blade depth and bevel adjusting locking levers
must be tight and secure before making a cut. If
the blade adjustment shifts while cutting it may cause
binding and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making the 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.
LOWER GUARD FUNCTION
a) Check the lower guard for proper closing
before each use. Do not operate the saw if the
lower guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally
dropped, the 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.
c) The lower guard may be retracted manually
only for special cuts such as “plunge cutsand
”and “compound cuts”. Raise the lower guard by
the retracting handle and as soon as the blade
enters the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
d) Always observe that the lower guard is
covering the blade before placing the 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 CIRCULAR SAWS
a) Do not use High Speed Steel (HSS)
saw blades.
b) Inspect the machine and the blade before
each use. Do not use deformed, cracked, worn or
otherwise damaged blades.
c) Never use the saw without the original
guard protection system. Do not lock the moving
guard in the open position. Ensure that the guard
operates freely without jamming.
d) Only use blades that comply with the
characteristics specified in this manual. Before
using accessories, always compare the maximum
allowed RPM of the accessory with the RPM of the
machine.
e) Do not use any abrasive wheels.
f) Use only blade diameter(s) in accordance
with the markings.
