Adjusting the Laser
Note: To test the laser function, the machine must be con-
nected to power.
 While adjusting the laser (e. g. when moving the tool
arm), never actuate the On/Off switch. Accidental start-
ing of the power tool can lead to injuries.
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
– Switch the laser beam on with switch 40.
Checking: (see figure S1)
– Draw a straight cutting line on the workpiece.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– 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.
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: (see figure S2)
– Screw the adjustment screw 53 in or out using a suitable
screwdriver until the laser beam is parallel 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.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
Checking: (see figure T1)
– Adjust an angle gauge to 90° and position it on the saw
table 15.
The leg of the angle gauge must be flush with the saw blade 12
over the complete length.
Adjusting: (see figure T2)
– Loosen clamping lever 41.
– Push the stop 44 completely to the rear.
– Loosen the lock nut of the stop screw 54 using a commer-
cial box-end or open-end spanner (size 10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Tighten clamping lever 41 again.
– Afterwards, retighten the lock nut of the stop screw 54
again.
In case the angle indicator 43 is not in a line with the 0° mark
of the scale 42 after the adjustment, loosen the screw 55
using a commercial cross-head screwdriver and align the
angle indicator along the 0° mark.
1 609 92A 2NV | (8.12.16)
Setting the Standard Bevel Angle 45° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
– Turn the stop 30 completely to the front.
– Loosen clamping lever 41 and tilt the tool arm by handle 8
leftward to the stop (45°).
Checking: (see figure U1)
– Adjust an angle gauge to 45° and position it on the saw
_table 15.
The leg of the angle gauge must be flush with the saw blade 12
over the complete length.
Adjusting: (see figure U2)
– Loosen the lock nut of the stop screw 56 using a commer-
cial box-end or open-end spanner (size 10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Tighten clamping lever 41 again.
– Afterwards, retighten the lock nut of the stop screw 56
again.
In case the angle indicator 43 is not in a line with the 45° mark
of the scale 42, firstly check the 0° setting for the bevel angle
and the angle indicator again. Then repeat the adjustment of
the 45° bevel angle.
Aligning the Scale for Mitre Angles
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
Checking: (see figure V1)
– Adjust an angle gauge to 90° and position it between the
fence 14 and the saw blade 12 on the saw table 15.
The leg of the angle gauge must be flush with the saw blade 12
over the complete length.
Adjusting: (see figure V2)
– Loosen all four set screws 57 with a cross-head screw-
driver and turn the saw table 15 together with the scale 17
until the leg of the angle gauge is flush with the saw blade
over the complete length.
– Retighten the screws again.
When the angle indicator 23 is not in line with the 0° mark of
scale 17 after adjusting, loosen screw 58 with a cross-head
screwdriver and align the angle indicator alongside the
0° mark.
Transport (see figure W)
Before transporting the power tool, the following steps must
be carried out:
– Loosen the locking screw 33 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Make sure that the depth stop 32 is pushed completely
inward and that adjusting screw 4 fits through the recess
without touching the depth stop when moving the tool
arm.
– Bring the machine into the transport position.
