When restarting a saw in the workpiece,
centre the saw blade in the kerf and check
that the saw teeth are not engaged into the
material. If the saw blade is binding, it may
travel up from the workpiece or kickback as the
saw is restarted.
Support large panels to reduce the risk of
blade pinching and kickback. Large panels
tend to sag under their own weight. Sup-
ports must be placed under the panel on both
sides, near the line of cut and near the edge of
the panel.
Do not use dull or damaged saw blades.
Unsharpened or improperly set blades pro-
duce narrow kerf causing excessive friction,
blade binding and kickback.
Before sawing, tighten the blade depth and
cutting angle adjustments. If the adjust-
ments change during cutting, the saw blade
can jam and kickback can occur.
Use extra caution when making "plunge
cuts" into existing walls or other blind ar-
eas. The protruding saw blade, when running
into hidden objects, can be jammed and cause
kickback.
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 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.
Check the operation of the lower guard
spring. If the guard and the spring are not
operating properly, they must be serviced
before use. The lower guard may operate
sluggishly due to damaged parts, gummy de-
posits or a build-up of debris.
The lower guard should be retracted manu-
ally only for special cuts such as "plunge
cuts" and "compound cuts". Raise the
lower guard with the retracting handle and
as soon as blade enters the material, the
lower guard must be released. For all other
sawing, the lower guard must operate auto-
matically.
Always observe that the lower guard is
covering the saw blade before placing
down the saw on a workbench or the floor.
An unprotected, coasting blade will cause the
saw to travel backwards, cutting whatever is in
its path. Be aware of the run-on period of the
saw.

Do not reach into the saw dust ejector with
your hands. They could be injured by rotating
parts.
Do not work overhead with the saw. In this
manner you do not have sufficient control over
the power tool.
Use suitable detectors to determine if util-
ity lines are hidden in the work area or call
the local utility company for assistance.
Contact with electric lines can lead to fire and
electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric
shock.
Do not operate the power tool stationary. It
is not designed for stationary operation.
Do not use high speed steel (HSS) saw
blades. Such saw blades can easily break.

Intended Use

The machine is intended for cutting wood length-
ways and crossways in straight lines and at mi-
tred angles of up to 45° on a firm surface.

Adjusting the Cutting Depth

(see figure
Before any work on the machine itself, pull the
mains plug.
To achieve an optimum cut, the saw blade
must not protrude the material by more
than 3 mm (maximum).
For adjusting the cutting depth loosen the clamp-
ing lever 23 and raise the saw from the base
plate 14, or lower it to the base plate, respec-
tively.
Raise for smaller cutting depths
Lower for greater cutting depths
Set the desired depth on the cutting depth
scale 24.
Tighten the clamping lever 23 again.
Clamping Lever
The clamping force of the clamping lever 23 can
be readjusted.
For this, unscrew the clamping lever and set it at
least 30° offset in anticlockwise direction, then
screw on again.
