Preparing For Operation - Bosch GCM 10 MX Professional Originalbetriebsanleitung

26 | English
When fitting the saw blade, make sure that the cutting
u
direction of the teeth (arrow direction on the saw
blade) matches the direction of the arrow on the pro-
tective guard.
– Place on the clamping flange (40) and the screw (39).
Press the spindle lock (29) until it engages and tighten
the screw by turning it anticlockwise.
– Push the retracting blade guard (5) forwards and down
until the screw (38) engages in the corresponding recess.
To do so, you may need to hold the tool arm against the
handle in order to generate sufficient pre-tension on the
retracting blade guard.
– Fasten the retracting blade guard (5) again (tighten
screw (38)).
– Push the lever (2) and guide the retracting blade guard
down again.
When attaching the clamping flange, ensure that the
u
wide side faces the saw blade. The saw blade cannot be
tightened if it is installed the other way round.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Transport safety lock (see figure F)
The transport safety lock (27) makes it easier to handle the
power tool when transporting it to various working locations.
Unlocking the power tool (work position)
– Press the tool arm down slightly by the handle (3) to re-
lease the transport safety lock (27).
– Pull the transport safety lock (27) all the way out.
– Slowly guide the tool arm upwards.
Note: Make sure that the transport safety lock is not pushed
in when working, otherwise the tool arm will not be able to
be swivelled to the required depth.
Locking the power tool (transport position)
– Swivel the depth stop inwards so that the tool arm can be
swivelled all the way downwards by the handle (3).
– Push the lever (2) while swivelling the tool arm down-
wards by the handle (3) until you can press the transport
safety lock (27) all the way in.
The tool arm is now securely locked and ready for transport-
ation.

Preparing for operation

Moving the fence (see figure G)
You have to move the adjustable fence (17) to saw bevel
angles.
– Loosen the wing bolt (21).
– Pull the adjustable fence (17) all the way out.
– Retighten the wing bolt (21).

After sawing the bevel angles, slide the adjustable fence
(17) back again (loosen the wing bolt (21); slide the fence
(17) all the way in; retighten the wing bolt).
Clamping the workpiece (see figure H)
To ensure maximum safety while working, the workpiece
must always be firmly clamped.
Do not saw workpieces that are too small to clamp firmly.
– Press the workpiece firmly against the fences (6) and
(17).
– Insert the supplied screw clamp (18) into one of the cor-
responding holes (8).
– Loosen the wing bolt (43) and adjust the screw clamp to
the workpiece. Tighten the wing bolt again.
– Tighten the threaded rod (44) to fix the workpiece in
place.
Releasing the workpiece
– To loosen the screw clamp, turn the threaded rod (44)
anticlockwise.
Setting mitre and bevel angles
Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Always tighten the locking knob (10) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.
Setting mitre angles (see figure I)
The mitre angle can be set between 47° (left side) and 52°
(right side).
– Loosen the locking knob (10) if it is tightened.
– Push the lever (11), turn the saw table (7) left or right by
the locking knob and set the required mitre angle using
the angle indicator (12).
– Retighten the locking knob (10).
For quick and precise setting of commonly used mitre
angles, detents (45) are provided on the saw table:
Left
0°
45°; 30°; 22.5°; 15°
– Loosen the locking knob (10) if it is tightened.
– Push the lever (11) and turn the saw table (7) left or right
to the required detent.
– Release the lever again. The lever must be felt to engage
in the detent.
– Retighten the locking knob (10).
Setting bevel angles (see figure J)
The bevel angle can be set between 0° and 45°.
– Loosen the clamping handle (26).
Right
15°; 22.5°; 30°; 45°
