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.
Safety instructions for plunge saws
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 with the blade ex-
posed. 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 guide plate of the saw will not
shift while performing the "plunge cut" when
the blade bevel setting is not at 90°. Blade shift-
ing 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.
Additional safety instructions for all saws with riv-
ing 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 in-
struction manual. Incorrect spacing, positioning
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
after plunge cutting. Riving knife causes interfer-
ence during plunge cutting and can create kick-
back.
d) For the riving knife to work, it must be engaged
in the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
e) Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
Additional safety instructions
• Never use abrasive wheels in the machine.
• Make sure that the riving knife is adjusted so that the
distance to the sprocket ring of the saw blade is not
more than 5 mm and that the sprocket ring does not
stick out more than 3 mm above the lower edge of
the riving knife.
• Make sure that the dust catching mechanism is cor-
rectly installed, as is described in this manual.
• Wear breathing protection. Always wear ear protec-
tion.
• Only those saw blades recommended in the manual
should be used.
• Replace the saw blades as described in this manual.
• If the electrical cable of this tool is damaged it must
be replaced by the manufacturer or the customer
service department or a similarly qualified specialist
in order to avoid dangers.
• Only use the recommended saw blades which cor-
respond to EN 847-1.
• Only use the manufacturer's original saw blades
with the number Ø 160 mm, 160 x 20 x 2.4.
• Do not use any saw blades which do not correspond
to the characteristics described in these operating
instructions. Saw blades may not be brought to a
stop by pressure on the machine from the side.
• Make sure that the saw blade is tightly assembled
and turns in the correct direction.
• Hold the equipment on the insulated handles, when
you undertake work in which the tool being used
could come into contact with hidden electrical wires,
or its own cable. Contact with a live power source
can electrify the metal parts of the tool and lead to
an electrical shock.
