4.5.2 Change of guide wheel
Proceed as follows to replace the deflection wheel:

Remove the saw wire from the deflection wheel
(see chapter 4.4 Change of saw wire, page 24).

Unfasten the countersunk screw 19 (Fig. 4) and
remove the cover 20 with the lower scraper.

Release the hexagon nut 21 (Fig. 4) counter
clockwise. To do so, keep a hold on the axle at
the fitted hexagon with an open-end wrench AF
10. Now remove the hexagon nut from the axle.
You can now pull the deflection wheel from the
axle.

Put a new deflection wheel onto the axle.

Afterwards, mount the hexagon nut and tighten
it by
clockwise turning.

Place the saw guard 20 with the lower scraper
onto the ram and tighten it with the countersunk
screw 19.

Open the fillister head screw 22 (Fig. 4) and
align the lower scraper with the deflection wheel
so that the scraper tongue just touches the
groove base of the deflection wheel. Tighten the
fillister head screw.

Now put the saw wire onto the deflection wheel
(see chapter 4.4 Change of saw wire, page 24).
4.6 Change of scraper
Danger
Pull the power plug during all
service work.
The scrapers keep the groove base of the drive and
deflection wheel clean. They must be replaced if they
are worn or defective.
4.6.1 Change of top scraper
Proceed as follows to replace the scraper:

Remove the saw wire from the drive wheel (see
chapter 4.4 Change of saw wire, page 24).

Unfasten the fillister head screw 14 (Fig. 3) and
remove the scraper 31 (Fig. 3) from the bracket.

Put a new scraper onto the bracket and fasten it
with the fillister head screw.

Align the scraper with the drive wheel so that
the scraper tongue just touches the groove base
of the drive wheel. Tighten the fillister head
screw.

Now put the saw wire onto the drive wheel (see
chapter 4.4 Change of saw wire, page 24).
4.6.2 Change of bottom scraper
Proceed as follows to replace the lower scraper:

Remove the saw wire from the deflection wheel
(see chapter 4.4 Change of saw wire, page 24).

Unfasten the fillister head screw 22 (Fig. 4) and
remove the scraper 32 (Fig. 4) from the cover.

Install a new scraper in the cover and fasten it
with the fillister head screw.

Align the scraper with the deflection wheel so
that the scraper tongue just touches the groove
base of the deflection wheel. Tighten the fillister
head screw.

Now put the saw wire onto the deflection wheel
(see chapter 4.4 Change of saw wire, page 24).
4.7 Setting for bevel cuts
For bevel cuts, the machine can be set to any angle
between 0 °and 60°.

In order to incline it, bring the machine into
home position and support it such that it is
possible to tilt the saw unit.

Release the two wing screws 23 (Fig. 1).

Adjust the angle according to the scale on the
gear case.

Afterwards, tighten the wing screws 23.
4.8 Tilting back the wire set
Caution: Risk of injury at the
blades. Sawing with the wire set
tilted to the rear requires you to
work with increased attentiveness!
The wire set can be tilted backwards to any angle
between 0 °and 45°.

Release the clamping lever 24 (Fig. 1).

Adjust the angle according to the scale on the
riving knife/splitter.

Then re-tighten the clamping lever.
