Working On Mouldings; Checking And Adjusting The Basic Settings - Bosch GCM 12 GDL Professional Manual Original

Working on mouldings

Mouldings can be sawn in two different ways:
Positioning of Base moulding
workpiece
– Placed against
the fence
– Lying flat on the
saw table
Furthermore, you can cut with or without the slide move-
ment depending on the width of the moulding.
Always check the set mitre and/or bevel angle first by mak-
ing trial cuts in scrap wood.

Checking and Adjusting the Basic Settings

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.
Adjusting the laser
Note: To test the laser function, the power tool must be con-
nected to the power supply.
While adjusting the laser (e.g. when moving the tool
u
arm), never activate the on/off switch. Starting the
power tool accidentally can lead to injuries.
– Bring the power tool into the work position.
– Turn the saw table (38) to the 0° detent (15). The lever
(12) must be felt to engage in the detent.
Checking (see figure T1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the glide arm (28) downwards using the
handle (1).
– Position the workpiece so that the teeth of the saw blade
line up with the cutting line.
– Hold the workpiece in this position and slowly guide the
glide arm upwards.
– Clamp the workpiece.
– Switch on the laser beams with the switch (60).
The laser beams must be the same distance away (left and
right) from the cutting line marked on the workpiece along
their entire length, even when lowering the glide arm.
Removing the laser protection cap (see figure T2)
– Loosen the two screws (63) on the laser protection cap
(27) using the hex key (4 mm) (17).
Note: To access the front screw on the laser protection
cap, the glide arm must be swivelled down slightly until
the hex key can be inserted through one of the slots on
the retracting blade guard.
Bosch Power Tools
Adjusting the flush alignment (see figure T3)
– Remove the laser protection cap (27).
1. Adjusting the right-hand laser beam:
Crown moulding
– Turn the rear set screw (64) using the hex key (18) until
the entire length of the right-hand laser beam is flush with
the cutting line marked on the workpiece.
This also moves the left-hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
2. Adjusting the left-hand laser beam:
– Turn the front set screw (64) using the hex key (18) until
the left-hand laser beam is the same distance away from
the cutting line marked on the workpiece as the right-
hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
– Reattach the laser protection cap (27).
Adjusting the parallelism (see figure T4)
– Remove the laser protection cap (27).
– Loosen the fastening screw (65) (by approx. 1–2 turns)
using the hex key (18). Do not unscrew the screw com-
pletely.
– Move the laser mounting plate to the right or left until the
laser beams are parallel with the marked cutting line on
the workpiece along their entire length.
– Hold the laser mounting plate in this position and
retighten the fastening screw (65).
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If required, use the set screws (64) to
align the laser beams again.
– Reattach the laser protection cap (27).
Adjusting the side deviation when moving the glide arm
(see figure T5)
– Remove the laser protection cap (27).
– Loosen the two fastening screws (66) (by approx. 1–2
turns) using the hex key (18).
Do not completely unscrew the screws.
– Move the laser housing to the right or left until the laser
beams no longer deviate at the sides when moving the
glide arm down.
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If required, use the set screws (64) to
align the laser beams again.
– Hold the laser housing in this position and retighten the
fastening screws (66).
– Reattach the laser protection cap (27).
Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table (38) to the 0° detent (15). The lever
(12) must be felt to engage in the detent.
Checking (see figure U1)
– Set an angle gauge to 90° and place it on the saw table
(38).
