Checking And Adjusting The Basic Settings - Bosch GCM 8 SDE Professional Manual Original

The length stop can be mounted on either side of the saw
table extension (13).
– Loosen the locking screw (53) and move the length
stop (36) over the clamping screw (54).
– Re-tighten the locking screw (53).
– Set the saw table extension (13) to the required length.
Special workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, there
should be no gap between the workpiece, fence and saw
table.
If necessary, you will need to manufacture special fixtures.
Replacing the Insert Plates (see figure R)
The red insert plates (19) can become worn after prolonged
use of the power tool.
Replace defective insert plates.
– Bring the power tool into the work position.
– Loosen the screws (55) using the hex key (4 mm) (34)
and remove the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate as far as possible to the right with
the screws (55) so that the saw blade does not come into
contact with the insert plate over the entire length of the
possible slide motion.
– Repeat the work steps in the same manner for the left-
hand insert plate.

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 (16) to the 0° detent (25). The lever
(22) must be felt to engage in the detent.
Checking (see figure S1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the tool arm downwards using the
handle (9).
– 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
tool arm back up.
– Clamp the workpiece.
– Turn on the laser beam using the switch (40).
Bosch Power Tools
The laser beam must be flush with the cutting line on the
workpiece along its entire length, even if the tool arm is
guided downwards.
Setting (see figure S2)
– Turn the set screw (56) with a suitable screwdriver until
the laser beam is parallel to the entire length of the cut-
ting line on the workpiece.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table (16) to the 0° detent (25). The lever
(22) must be felt to engage in the detent.
Checking (see figure T1)
– Set an angle gauge to 90° and place it on the saw table
(16).
The leg of the angle gauge must be flush with the saw blade
(12) along its entire length.
Setting (see figure T2)
– Loosen the clamping lever (41).
– Slide the stop (44) all the way back.
– Loosen the lock nut of the stop screw (58) using a com-
mercially available box-ended or open-ended spanner
(size 10 mm).
– Turn the stop screw as far in or out as needed until the leg
of the angle gauge is flush with the saw blade along its en-
tire length.
– Re-tighten the clamping lever (41).
– Then re-tighten the lock nut of the stop screw (58).
If the angle indicator is not aligned with the 0° mark on the
scale (30) following adjustment, loosen the screw (57) us-
ing a commercially available cross-headed screwdriver and
align the angle indicator along the 0° mark.
Setting the Standard 45° Mitre Angle (left)
– Bring the power tool into the work position.
– Turn the saw table (16) to the 0° detent (25). The
lever (22) must be felt to engage in the detent.
– Remove the left-hand adjustable fence (15)
– Turn the left-hand stop (29) until the standard 45° mitre
angle engages at the arrow mark.
– Loosen the clamping lever (41).
– Swivel the tool arm by the handle (9) to the left until the
stop screw (59) rests on the stop (29).
Checking (see figure U1)
– Set an angle gauge to 45° and place it on the saw table
(16).
The leg of the angle gauge must be flush with the saw blade
(12) along its entire length.
Setting (see figure U2)
– Loosen the lock nut of the stop screw (59) using a com-
mercially available box-ended or open-ended spanner
(size 10 mm).
