English Operating Manual – Snowthrower

With the coupling levers (1 and 2)
released, choose a forwards gear
with shift lever (6).
Press coupling lever for worm
drive (1) and hold it down; worm
and throw turbine are driven.
Press coupling lever for the drive
system (2) and hold it down; the
machine moves forwards and
clears the snow. As long as this
lever is pressed, the coupling lever
for the worm drive (1) is locked in
position and you can let go of it.
If you want to change gear, first
release the coupling lever for the
drive system (2) and then change
gear with the shift lever (6).
Working on slopes
Risk of injury from machine
tipping over
Work slowly and carefully, especially
when 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 gradient greater than 20 %.
Tips on clearing snow
Clear snow immediately after it has
stopped snowing; later on, the
underneath layer will ice up and
will make clearing the snow more
difficult.
If at all possible, clear snow in the
direction of the wind.
Clear the snow in such a way that
the tracks you have cleared
overlap slightly.
Set the direction and
distance of throw
Figure 8
Risk of injury
Do not set the flap (2) of the throw-
out chute (3) in the direction of
people, animals, windows, cars and
doors.
Set the direction of throw
Put the throw-out chute (3) in the
desired direction by rotating the
handle (Figure 1, item 7)
Set the throw distance
The steeper the angle of the flap (2)
is set, the higher and further the
snow will be ejected.
For machines with lever (Figure 1,
item 5): press lever forwards to set
the flap (2) higher and back for
lower.
For machines without lever: loosen
knob (1) and set flap (2) higher or
lower as required.
Start the engine
Figure 2
Danger
If you start the engine in an enclosed
space, move the machine
immediately afterwards into the open
air. Never leave the engine running
in an enclosed space.
Before starting the engine, release
coupling levers (Figure 1, items 1
and 2)/coupling bar (Figure 1,
item 1).
Check contents of fuel tank and oil
level, as required fill up with oil and
fuel (see “Engine instructions”).
Start with pull starter
Set shut-off valve (10), if this is
present, to “ON”.
Put spark-plug connector (8) onto
the spark plug.
Set throttle lever (7) to “ ”.
For a cold start, set choke (2) to
”/“ON”.
Insert ignition key (1) in the ignition
lock.
Press primer knob (3) once. In cold
weather press it twice or three
times.
Pull the pull starter (4) slowly until
some resistance is felt, then
quickly and vigorously. Do not let
the pull starter recoil quickly but
lead it back slowly.
Set choke (2) back progressively
to “OFF”.
Start with electric starter
(optional)
To start the engine, the electric
starter must be connected to the
mains power supply.
Risk of electric shock
Make sure that the mains supply
network is protected with a fault
current circuit-breaker. If required,
have an appropriate circuit-breaker
fitted, but only by a trained
electrician.
For connecting the electric starter to
the mains, use only extension cables
(not supplied with the machine)
which are approved for use in the
open air and which are protected by
an earth wire, e.g. up to a maximum
length of 50 m:
– H07RN-F 3x1.5 mm² up to –25 °C
H07BQ-F 3x1.5 mm² up to –40 °C.
Caution
If the electric starter is not connected
properly, damage could occur to the
machine or in its vicinity.
Make sure that the mains supply
network
– is operating in conformity with the
specifications on the starter
identification plate (Figure 2,
item 9) at 220–230 V and 50 Hz
is protected by an appropriate fuse
system.
Put spark-plug connector (8) onto
the spark plug.
Set throttle lever (7) to “ ”.
Insert ignition key (1) in the ignition
lock, but do not turn it.
Connect extension cable first with
the plug (5) and then with a mains
socket.
Set choke (2) to “OFF”.
Press starter button (6) long
enough (max. 5 sec.) for the
engine to start. For a cold start, set
choke (2) while the starter button is
being pressed to “ ”. Wait at least
10 sec. before attempting to start
the engine again.
As required, set the choke (2)
progressively back to “OFF”.
Separate the extension cable first
from the mains and then from the
electric starter.
