Figure 4
The landing skids (1) can be used to adjust
the distance between the ground and the
clearing plate (4) in such a way that no
parts of the ground (such as soil or stones)
are picked up.

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.
ƽ Danger
Risk of injury!
– Keeps persons, especially children,
and pets away from the hazardous
zones.
– Operate the machine only in a safe and
perfect working condition.
– Always observe the safety distance to
the circling tool prescribed by the guide
bar.
– Check the area where the machine is to
be used and remove all objects that can
get picked up and thrown out by the ma-
chine.
– Work only with adequate lighting.
– Only use the machine in walking speed.
– Work slowly and safely especially on
uneven or loose paths and while revers-
ing.
– Adjust the distance between the snail
casing and the underground floor in
such a way that the appliance does not
pick up any foreign bodies (such as
stones).
ƽ
Danger
Risk of suffocation on account of carbon
monoxide! Only operate the combustion
engine while out in the open.
ƽ
Danger
Risk of fire! Keep the motor and exhaust
free of dirt and escaping oil.
Note: Follow the national/ local regulations
for the usage times (ask the local authori-
ties, if required).
ƽ Danger
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
– Clear up immediately after the snowfall;
otherwise, the lower layer becomes ice
and makes clearing difficult.
– If possible, clear the snow in the direc-
tion of the wind.
– Clear the snow in such a way that the
clearing tracks overlap a little.
ƽ
Danger
Risk of injury!
Danger of tipping if gradient is too high.
– Do not use the appliance on slopes with
an inclination greater than 20%.
– Work slowly and cautiously, especially
while changing the direction of travel.
– Drive up and down the slope - never di-
agonally to the slope.
– Pay attention to hurdles - do not work
close to the inclination.

ƽ
Danger
Risk of injury! Do not direct the flap (2) of
the discharge shaft (3) towards persons,
animals, windows, cars and doors.
 Bring the discharge shaft (3) to the de-
sired direction by turning the crank (fig-
ure 1, item 5).
Deeper the flap (2), so much higher and far-
ther will be the snow discharge.

Loosen the wing nut (1) and adjust the
flap (2) higher/ lower as required.


Read the operating instructions of the
engine manufacturer before start-up
and follow the safety instructions care-
fully.
 Release the clutch lever for the auger
drive and travel drive before starting.
 Check tank contents and oil level; refill
oil and fuel (see "Engine Instructions
Booklet").
 Insert the ignition plug into the spark
plug.
 Set the gas lever to "fast".
 Set the choke for cold start to "ON/
CHOKE".
 Insert the ignition key into the ignition
lock, do not turn it.
 Press cold start help (Tupfer) once;
press it twice to seven times during cold
weather (depending on the engine
type).
 Pull the rope starter slowly till you feel
the resistance and then give it a quick
and hard tug. Do not allow the rope
starter to recoil immediately - just let it
go back slowly.
 Reset the choke back to "RUN/OFF" in
a step-by-step manner, if the engine is
running.
