Page: 20 / 285

DANGER
Don’t operate the machine without the protective
devices that belong to it.
In order to facilitate cutting as closely as possible to
edges and walls etc., the forward section of the saw
arm can be turned and fitted in the reversed position
so that the cutting disc, when seen from behind, is
positioned to the right of the saw arm.
1.
Remove the spray jets from the guard.
2. Slacken the three clamping nuts on the forward
section of the saw arm approx. one complete
turn.
3. Release the tension on the drive belt by turning
the belt tensioning cam counterclockwise care-
fully as far as it will go (until resistance is felt,
i.e. approx. ¼ of a turn).
4. Remove the three clamping nuts and the two
securing screws from the forward section of the
saw arm, then remove the drive belt cover and
the forward section of the saw arm.
5. Release the four securing screws on the rear
drive belt cover and remove the cover.
6. Remove the stop screw that limits rotation of the
forward section of the saw arm.
7. Place the drive belt carefully over the drive pulley.
8. Fit the forward section of the saw arm onto the
rear section of the saw arm. Fit only the middle
clamping nut. Tighten the nut only finger-tight.
9. Rotate the disc guard until the opening is at the
rear.
10. Tension the drive belt by turning the belt tension-
ing cam clockwise carefully as far as it will go
(until resistance is felt, i.e. approx. ¼ of a turn).
11. Secure the forward drive belt cover with the two
clamping nuts and two securing screws.
12. Tighten the three clamping nuts securely (18
Nm).
13. Fit the rear drive belt cover and secure it with the
four screws.
14. Rotate the disc guard until the opening is at the
front.

the blade guard.
6.5 Locking rotary movement of the guide
wheels
5
WARNING
When working on roofs, scaffolds and/or slight
slopes, always lock the guide wheels to prevent the
saw rolling away inadvertently and possibly falling.
Use the built-in safety feature which allows you
to lock the wheels by fitting them in the reversed
position (turned through 180°).
1. Release the guide wheel mounting screws and
remove the guide wheels.
2. Reverse the guide wheels (turn through 180°)
and refit the mounting screws.
3. Check that the guide wheels are mounted se-
curely.
6.6 Saw carriage
6
NOTE
We recommend use of the saw carriage when the
machine is used extensively for floor sawing.
NOTE
Especially when using the machine in this config-
uration for the first time, check to ensure that the
throttle cable is correctly adjusted. When the throttle
control is pressed fully, the machine must run up to
maximum speed. If this is not the case, the throttle
cable can be readjusted by way of the cable tensioner.
CAUTION
Switch off the saw at the stop switch immediately if
the throttle cable on the saw carriage gets stuck.
DANGER
Before starting the engine, check that the saw is
correctly secured to the saw carriage.
1. Move the cutting depth adjustment lever into the
upper position.
2. Open the hold-down device by releasing the
screw knob.
3. Fit the saw into the forward mount with the
wheels as shown and swing the grip of the saw
under the hold-down device.
4. Secure the saw by tightening the screw knob.
5. Fit the water tank after filling it.
6. Adjust the grip to a convenient working height.
7. Adjust the guard to the correct position.
