Ceiling Strips/Mouldings (According to US Standard)

Checking and Adjusting the Basic Adjustment

To ensure precise cuts, the basic adjustment of the machine 
must be checked and adjusted as necessary after intensive 
use.
A certain level of experience and appropriate specialty tools 
are required for this.

A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.

Adjusting the Laser

– Bring the power tool into the table saw working position. 

(see “Working Position”, page  47)

– Turn the saw table 

22

 to the 0 ° detent 

27

. The lever 

26

must be felt to engage in the detent.

Checking:

 (see figure

M1)

– Draw a straight cutting line on the workpiece.
– Push button 

17

 and slowly guide the tool arm downward 

with the handle 

18

.

– Align the workpiece in such a manner that the teeth of the 

saw blade are in alignment with the cutting line.

– Hold the workpiece in this position and slowly guide the 

tool arm upward again.

– Clamp the workpiece.
– Switch the laser beam on with switch 

36

.

The laser beam must be in alignment with the cutting line on 
the workpiece over the complete length, also when the tool 
arm is lowered.

Adjusting the Parallelism:

 (see figure

M2)

– Undo the rubber cap 

50

.

– Screw the adjustment screw 

51

 in or out using a suitable 

screwdriver until the laser beam is parallel with the cutting 
line on the workpiece over the complete length.

Adjusting the Flush Levelling:

 (see figure

M3)

An adjustment screw 

52

, which is located below the opening 

marked with “R/L”, is used for adjustment of the flush leve-
ling.
– Screw the adjustment screw 

52

 in or out with the slotted 

screwdriver provided until the parallel laser beam is flush 
with the cutting line on the workpiece over the complete 
length.

One rotation in anticlockwise direction moves the laser beam 
from left to right; one rotation in clockwise direction moves 
the laser beam from right to left.

Adjusting the Lateral Deviation while Moving the Tool 
Arm:

 (see figure

M4)

– Open the side rubber cap 

53

.

– If the laser beam 

moves towards the left

 when lowering 

the tool arm, turn adjustment screw 

54

 clockwise using a 

suitable screwdriver.
If the laser beam 

moves towards the right

, turn adjust-

ment screw 

54

 anticlockwise.

– After adjusting, check the flushness with the cutting line 

again. If required, align the laser beam with the adjustment 
screw 

52

 again.

When the ceiling strips/mouldings are to be sawn lying flat on the saw table, the standard mitre angles 
of 31.6 ° (horizontal) and 33.9 ° (vertical) must be set.
The following table contains instructions for sawing ceiling strips/mouldings.
