Risk of injury
Keep other people, in
particular children and
domestic animals away from the
danger area.
Operating the machine only when it is
in the faultless and safe-to operate
condition.
Inspect the ground over which the ma-
chine is to operate and remove all
objects which could be picked up by
the machine and hurled out.
Working only when there is sufcient
illumination. Always be sure of your
footing, and keep a rm hold on the
handle, walk, never run.
If the machine should start to vibrate
abnormally, stop the engine and check

immediately for the cause. Vibration is
generally a warning of trouble.
Work slowly and carefully, especially on
uneven or non-hard-surfaced paths, or
when you are moving backwards.
Never operate the machine without
proper safety guards.
Do not overload the machine capacity by
attempting to clear snow at too fast a
rate.
Set the distance between worm housing
and ground in such a way that no
extraneous material (e.g. stones) is
taken up by the machine.
If the machine strikes extraneous
material (e.g. stones) or exhibits
unusual vibrations, switch off the
machine and inspect it for damage. Get
any damage you discover repaired
before you work the machine again.
Befor you put the machine to work, let
the engine run to warm up.
When you have nished work, leave the
engine running for a few mintues to
eliminate the moisture.

Risk of injury from machine
tipping over
Work slowly and carefully,
especially if you change direction.
Guide the machine up or down the slope
not crosswise to it.
Watch out for obstacles, do not work
near inclines.
Do not use the machine on slopes with a
radient greater than 20%
Let engine and machine adjust to
outdoor temperatures before starting
to clear snow.
Clear snow immediately after it has
stopped snowing, later on the
underneath layer will ice up and will
make clearing the snow more
difcult.
If at all possible, clear snow in the
direction of wind.
Clear the snow in such a way that
tracks you have cleared, overlap
slightly.
Starting the engine (see “Starting
the engine”)
Starting the engine (see “Starting
the engine”)
Press the coupling lever (1) and
hold it down; the worm in use.
As a result of the worm
establishing contact with ground,
the machine moves forward.
If you want to increase the travel
speed, raise the side handle (8)
slightly; the worm has greater
contact with the ground and then
drives the machine forward faster.
This leads (if repeated frequently)
to the rubber lip on the worm
wearing down faster.
To reduce the travel speed, press
down on the side handle.

Risk of injury
Before doing any work on this
machine
Select a gear with shift lever (6)
-- Forward: “1” (slow) up to “5”
-- Reverse: “R” (slow) and “R”
(fast)
-- Remove the ignition key and the
spark-plug connector.
-- Wait until the engine has cooled down.

vehicle in a horizontal position.
Secure the machine against rolling or
slipping.
gear or change gear.
The caterpillar track (1) is correctly
adjusted if it can be forced down by
hand by 10-12 mm. If it can be forced
down by a greater or lesser amount, it
must be adjusted.
Remove the shear-off bolt and nut,
clean place of attachment and
lubricate it.
Use a new shear bolt and lock-nut to
replace the broken one.

forward gear (higest gure).
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
rmly and must be slackened (see
“making adjustments to the
coupling cable”).

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 (gure 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
lter 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.
