– Slowly guide the retracting blade guard 4
down until the cutting disc is covered off.
– Make sure that the retracting blade guard 4
operates properly.
After mounting the cutting disc and before
switching on, check whether the cutting disc is
properly mounted and if it can rotate freely.
– Make sure that the cutting disc does not
graze against the retracting blade guard 4,
the blade guard 19 or against other parts.
– Run the machine for approx. 30 seconds.
Should significant vibrations occur, switch
off the machine immediately; remove and in-
stall the cutting disc again.
Operation
Before any work on the machine itself, pull
the mains plug.
Transport Safety (see figure C)
The transport safety-lock 15 enables easier han-
dling of the machine when transporting to vari-
ous working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 3 down a lit-
tle in order to relieve the transport safety-
lock 15.
– Pull the transport safety-lock 15 completely
outward.
– Guide the tool arm slowly upward.
Note: When working, pay attention that the
transport safety-lock is not pushed inwards.
Otherwise, the tool arm cannot be lowered to
the requested depth.
Securing the Machine (Transport Position)
– Guide the tool arm downward until the trans-
port safety-lock 15 can be pushed complete-
ly inward.
For additional information on transport, see

Adjusting the Cutting Angle
(see figure D)
The miter angle can be set in a range from 0° to
45°.
Frequently used mitre angles are identified on
the angle stop 7 with appropriate markings. The
0° and 45° position are set at the respective
end stop.
– Loosen the locking screws 13 for the angle
stop with the supplied ring spanner 14
(15 mm).
– Adjust the desired angle and firmly tighten
both locking screws 13 again.
Displacing the Angle Stop (see figure D and E)
When cutting workpieces wider than 140 mm,
the angle stop 7 can be displaced to the rear.
– Completely unscrew locking screws 13 with
the supplied ring spanner 14 (15 mm).
– Move the angle stop 7 toward the rear by one
or two holes to the desired clearance.
– Adjust the desired angle and firmly tighten
both locking screws 13 again.
Clamping the Workpiece (see figure E)
To ensure optimum working safety, the work-
piece must always be firmly clamped.
Do not saw workpieces that are too small to
clamp.
Long workpieces must be underlaid or support-
ed at their free end.
– Place the workpiece against the angle stop 7.
– Slide the clamping spindle 8 against the
workpiece and firmly clamp the workpiece
with the spindle handle 10.
Loosening the Workpiece
– Loosen the spindle handle 10.
– Tilt up the quick release 9 and pull the clamp-
ing spindle 8 away from the workpiece.
