Setting Mitre And Bevel Angles - Bosch GCM 12 GDL Professional Manual Original

38 | English
When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence (5) outwards depending
on the cutting direction, or remove it completely.

Adjusting the damping of the glide arm (see figure F)
The glide mechanism of the glide arm (28) is preset at the
factory and is not damped when the power tool is delivered.
The damping of the glide mechanism can be adjusted using
the damper (53):
Hard – for more controlled work movements;
Soft – for fast saw cuts.
– For softer damping, loosen the two set screws (54) using
the hex key (4 mm) (17)
– or
– tighten the two set screws (54) for harder damping.
Clamping the workpiece (see figure G)
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 (5).
– Insert the supplied screw clamp (19) into one of the cor-
responding holes (55).
– Loosen the wing bolt and adjust the screw clamp to the
workpiece. Tighten the wing bolt again.
– Tighten the threaded rod (57) to fix the workpiece in
place.
Releasing the workpiece
– To loosen the screw clamp, turn the threaded rod (57)
anticlockwise.

Setting mitre and bevel angles

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 (11) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.

– Loosen the locking screw (52).
– Pull the left-hand adjustable fence (5) all the way out.
– Loosen the locking screw (52).
– Pull the left-hand adjustable fence (5) all the way out.

– Remove the locking screw (52).
– Loosen the locking screw (52).
– Pull the right-hand adjustable fence (5) all the way out.

Adjusting the horizontal mitre angle
Setting Standard Mitre Angles (see figure H)
For quick and precise setting of commonly used mitre
angles, detents (15) are provided on the saw table:
45°; 31.6°; 22.5°; 15°
– Loosen the locking knob (11) if it is tightened.
– Pull the lever (12) and rotate the saw table (38) 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 (11).
Setting Any Mitre Angle (see figure I)
The mitre angle can be set between 52° (left side) and 60°
(right side).
– Loosen the locking knob (11) if it is tightened.
– Pull the lever (12) and at the same time press the locking
clamp (10) until this clicks into the slot provided for it.
This means the saw table can now move freely.
– Turn the saw table (38) left or right by the locking knob
until the angle indicator (58) shows the required mitre
angle.
– Retighten the locking knob (11).
– To loosen the lever (12) again (for setting standard mitre
angles), pull the lever upwards.
The locking clamp (10) springs back into its original posi-
tion and the lever (12) can click back into the detents
(15).
Adjusting vertical mitre angles
The bevel angle can be set between 47° (left side) and 47°
(right side).
For quick and precise setting of frequently used bevel
angles, stops have been provided for the angles 0°, 22.5°,
45° and 47°.
Setting the left-hand bevel angle range (45° to 0°)
– Pull the left-hand adjustable fence (5) all the way out.
