the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
Clutch bow
(only STH 953 W)
When the user releases this lever, the au-
ger drive will turn off and the machine will
stop moving.
Clutch lever for snail drive
(Not STH 953 W)

releases this clutch lever.
This lever can be stopped in a depressed
state (not STH 5.56 W) if the user presses
the clutch lever for travel drive and keeps it
depressed. Both the levers jump back as
soon as the user releases the clutch lever
for the travelling drive. The auger and travel
drive are switched off simultaneously.

Start up

Danger
Risk of injury!
Before doing any work on the machine:
Switch off engine.
Pull out the ignition key and the ignition
plug.
Allow engine to cool down.
Check the machine
Perform a visual inspection before each
use.
Check and ensure that all safety equip-
ment, operator control elements and the
corresponding clutch tensions/cables
and screw fittings are not damaged and
are tight.
Replace damaged parts before opera-
tions.
Not STH 953 W:
Check clutches for snail and travel drive
(see "Maintenance tasks").
STH 8.66 W, STH 10.66 W Crt, STH
10.71 W, STH 13.84 W:
Check switching lever (see "Mainte-
nance tasks").
Check oil level
Check oil level; refill engine oil if re-
quired (see "Engine Instruction Book-
let").
Refuelling
Danger
Risk of explosion and fire!
– Only use the fuels specified in the Oper-
ations Manual of the engine manufac-
turer.
– Do not refuel the machine in enclosed
spaces.
– Smoking and naked flames are strictly
prohibited.
– Ensure that no fuel reaches the hot
open surfaces.
– Fuel up only when the engine is
switched off and is cold.
– Never tank up the fuel tank fully. Wipe
off spilled fuel.
– Store fuel only in suitable containers.
Fuel up (for type of fuel see "Engine In-
struction Booklet"); close the lid of the
tank and wipe off fuel residues.
Check the tyre pressure
(Not STH 953 W)
For transportation, the tyres may show a
higher level of air pressure.
Check air pressure in the tyres; adjust it
if required (approx. 1 bar).
Adjust the machine to suit the snow
and ground conditions
Setting the working position
(machines with track drive)
Figure 4
Choose a suitable position using the ad-
justment lever (1).
– Position I: For heavy and icy snow. au-
ger is pressed to the ground.
– Position II: For normal snow conditions.
– Position III: To clear uneven paths or to
transport the machine. The auger has a
greater distance to the ground.
Adjusting the clearing plate
(only STH 953 W)
Figure 10
If the machine is sitting on even ground, the
auger (1), clearing plate (2) and wheels (3)
must touch the ground simultaneously.
– A clearing plate that is adjusted too high
will cause the snow to be thrown to the
rear.
– A clearing plate that is positioned too
low will wear faster.
Tilt the appliance rearward.
Loosen nuts (5).
Adjust the clearing plate higher or lower
(as required) and reattach.
Tilt the machine backwards, check ad-
justment and repeat if necessary.
Adjusting the skids
(Not STH 953 W)
Figure 7
The landing skids (1) can be used to adjust
the distance between the ground and the
clearing plate (5) in such a way that no parts
of the ground (such as soil or stones) are
picked up.
Machines with track drive: Set the gear
lever to position II.
Loosen the nuts (2) on both the sides of
the appliance.
Adjust the landing skids according to
the underground surface: Set it lower for
uneven or loose parths; higher for even
roads and paths.
Fasten the landing skids with nuts (2) in
such a way that they uniformly touch the
ground from the bottom.
