forward gear (higest figure).
Having release the coupling lever(2),
push the machine forwards.
While you are pushing the machine,
set shift lever (6) to the fastest
reverse gear and then set it to the
fastest forward gear.
If some resistance is felt while you
are pushing the machine or change
gear, you need to slacken the
coupling cable (see “making
adjustements to the coupling cable”)
While you push the machine,
press the coupling lever (2). The
wheel/caterpillar tracks must become
blocked. If not, tighten the coupling
cable a little (see “making
adjustments to the coupling cable”).
If you have not been able to perfect
adjustment or if in doubt about the
result, see “Checking the drive
system”.
Press the left coupling lever (1)
forwards (direction), at the same
time press down rubber (3).
Coupling cable (5) must be a little
slacker. Slacken it if necessary
(see “making adjustments to the
coupling cable”).
Release coupling lever (1). There
must be no slackness on the
coupling cable (5) but it must not
be tight either. Adjust if necessary
(See “making adjustments to the
coupling cable”).
The coupling lever (1) must allow
itself to be pressed down
completely. If it does not, the
coupling cable is tightened too
firmly and must be slackened (see
“making adjustments to the
coupling cable”).

Set setting lever (figure 4, item 1)
to position III (transport).
Set shift lever (6) to the fastest
For coupling cables with adjusting
sleeves (6)
-- Tighten: loosen nut (7) and screw
adjusting sleeves (6) against it.
-- Slacking: loosen nut (7) and screw
adjusting sleeves (6) against it.
For coupling cables with adjusting
sleeves (6)
For coupling cables with load-removal
spring (8): before making an
adjustment, the spring must be
unhooked and afterwards hooked on
again. The coupling cable is
correctly adjusted when the spring
expends 2 to 3 cm when coupling
takes place.
-- Tighten: Screw Lock-nut (9) upwards
-- Slacken: Screw Lock-nut (9)
downwards
Loosen screw to frame cover; if
necessary tip the machine forward.
With the coupling lever for the
drive system released (figure 1,
item 2) change into all gears; in
doing so the friction wheel (2)
should not come into contact with
the drive wheel (3). If it does,
slacken the coupling cable (see
“making adjustments to the
coupling cable”).
As required clean the drive wheel
and the rubber on the friction
wheel; they must be free of
grease.
If necessary, remove ice on parts
which is iced over.
Take care when tipping the machine
to see that
-- The machine stays balanced and
-- No fuel or oil runs into the air
filter or out of the machine.
If the worm is running irregularly at the
constant engine speed, the tension of the
V-belt (5) must be adjusted.
If there is an additional hole (3b) on
the coupling lever (1), hook the
coupling cable (2) into the higher
hole (3b).
If there is no additional (higher) hole
or it is already in use, then
-- remove the V-belt cover (4).
-- Hook spring (6) at the end of the
coupling cable into the next highest
hole (from 7a to 7b, from 7b to 7c).
-- Replace V-belt cover.
