Safety instructions
Never use damaged or incorrect saw blade
washers or bolts. The saw blade washers and
bolts were designed especially for your saw to
ensure optimum performance and operational
safety.
Causes and prevention of kickback:
Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to jerk up and out of the
workpiece towards the operator.
If the blade is pinched or bound by the closing
kerf, it stalls, and the action of the motor
drives the tool back towards the operator.
If the saw blade is twisted or misaligned in the
cut, the teeth at the back edge of the blade
can catch in the surface of the workpiece,
causing the blade to spring out of the kerf and
back towards the operator.
Kickback is the result of misuse of the saw or
incorrect operating procedures and conditions.
It can be avoided by taking appropriate precau-
tions as described below.
Grip the saw tightly with both hands and
position your arms to resist kickback
forces. Always position your body to one
side of the blade, never in line with the
blade. If kickback occurs, the saw may jump
backwards, but kickback forces can be con-
trolled by the operator if the appropriate pre-
cautions are taken.
If the saw blade sticks or you interrupt
work, switch the saw off and hold it
motionless in the workpiece until the saw
blade has come to a standstill. Never try to
remove the saw from the workpiece or pull
it back while the blade is in motion, as this
may trigger kickback. Investigate and take
corrective action to eliminate the cause of the
saw blade sticking.
To restart a saw which is in the workpiece,
centre the saw blade in the kerf and check
that the saw teeth are not engaged in the
material. If the saw blade is sticking, it may
move out of the workpiece or cause kickback
when the saw is restarted.
Support large panels to reduce the risk of
kickback due to a stuck saw blade. Large
panels may sag under their own weight. Sup-
ports must be placed under the panel on both
sides, near the kerf and near the edge of the
panel.
Never use blunt or damaged saw blades.
Saw blades with blunt or misaligned teeth
produce a narrow kerf which causes excess
friction, sticking of the blade and kickback.
Tighten the blade depth and bevel locking
levers before making a cut. If the settings
change during operation, the saw blade may
stick and cause kickback.
Be particularly careful when performing
"plunge cuts" into existing walls or other
blind areas. The protruding blade may become
stuck in hidden objects and cause kickback.
Before using the saw, always check that
the lower protective cover closes properly.
Do not use the saw if the lower protective
cover does not move freely and close
instantly. Never clamp or tie the lower pro-
tective cover open. If the saw is accidentally
dropped, the lower protective cover may be
bent. Open the protective cover with the
retracting handle and make sure that it moves
freely and does not touch the saw blade or
other parts in any angles or depths of cut.
Check the operation of the spring for the
lower protective cover. If the lower protec-
tive cover and the spring do not work
properly, have the saw serviced before
using it. Damaged parts, sticky residue or an
accumulation of debris may cause the lower
protective cover to work sluggishly.
Only open the lower protective cover by
hand for special cuts such as "plunge cuts
and angled cuts." Open the lower protec-
tive cover using the retracting handle and
release the handle as soon as the saw
blade enters the workpiece. For all other
cuts, the lower protective cover must function
automatically.
Make sure that the lower protective cover
is covering the saw blade before putting
the saw down on the workbench or the
floor. An unprotected, coasting saw blade
will cause the saw to walk backwards, sawing
whatever is in its path. Be aware of the time it
takes for the blade to stop after the switch is
released.
