Preparing For Operation - Bosch GCM 8 SDE Originalbetriebsanleitung

Mounting with SDS Bolt (see figure C)
Removing the Saw Blade:
– Bring the power tool into the working position.
– Hold the spindle lock 47 pressed and unscrew the SDS
bolt 51 in clockwise direction (left-hand thread!).
– Remove the clamping flange 49.
– Press locking switch 9 and swing back the retracting blade
guard 11 to the stop.
– Hold the retracting blade guard in this position and remove
the saw blade 12.
– Slowly guide the retracting blade guard downward again.
Mounting the Saw Blade:
If required, clean all parts to be mounted prior to assembly.
– Press locking switch 9, swing back the retracting blade
guard 11 to the stop and hold it in this position.
– Place the new saw blade onto the interior clamping flange
50.
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Slowly guide the retracting blade guard downward again.
– Attach the clamping flange 49 and the SDS bolt 51. Press
the spindle lock 47 until it engages and tighten the SDS
bolt in anticlockwise direction.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure D)
The transport safety-lock 39 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 8 down a little in order to
relieve the transport safety-lock 39.
– Pull the transport safety-lock 39 completely outward.
– Guide the tool arm slowly upward.
Securing the Machine (Transport Position)
– Loosen the locking screw 35 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Screw adjusting screw 4 completely upward.
– To lock the saw table 16, tighten the locking knob 21.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– Guide the tool arm downward until the transport safety-
lock 39 can be pushed completely inward.

Preparing for Operation

Extending the Saw Table (see figure E)
Long workpieces must be underlaid or supported at their free
end.
The saw table can be extended left and right with the saw-ta-
ble extensions 13.
Bosch Power Tools
– Push clamping lever 17 upward.
– Pull out the saw-table extension 13 to the desired length.
– To lock the saw-table extension, push clamping lever 17
down again.
Moving the Fence (see figure F)
When sawing mitre/bevel angles, you have to pull the left-
hand or right-hand adjustable fence 15 outward depending
on the cutting direction, or remove it completely.
Mitre/Bevel Angle
Vertical Horizontal
0°– 47° ≤ 44°
(leftward) (rightward/
leftward)
0°– 47° ≥ 45°
(leftward) (rightward/
leftward)
0°– 47° ≤ 44°
(right- (rightward/
ward) leftward)
0°– 47° ≥ 45°
(right- (rightward/
ward) leftward)
Clamping the Workpiece (see figure G)
– Press the workpiece firmly against the fence 14.
– Insert the material clamp 29 provided into one of the holes
37 intended for it.
– Adapt the threaded rod 52 of the screw clamp to the work-
piece height.
– Firmly tighten the threaded rod 52, thus fastening the
workpiece.
Adjusting Mitre Angles
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use (see "Checking and Adjusting the Basic Adjustment",
page 34).
Adjusting Standard Mitre Angles (see figure H)
For quick and precise adjustment of commonly used mitre an-
gles, detents 25 have been provided for on the saw table:
Left
15°; 22.5°; 31.6°; 45°
– Loosen the locking knob 21 in case it is tightened.
– Pull lever 22 and rotate the saw table 16 left or right to the
requested detent.
– Release the lever again. The lever must be felt to engage in
the detent.
– Tighten the locking knob 21 again.
