NOTE Do not make more than 3/4 attempts,
otherwise you risk flooding the engine.
Check the possible causes for a non-start
in the "Problems identification table".
6.3.4 Electric start-up
Make sure that the electricity
supply is duly earthed and fitted with
an automatic circuit breaker.
1. Insert the plug (fig. 15.G) into a
230 V power supply socket.
2. Press the start button to start the engine.
3. Once the engine is running, remove
the plug from the socket.
6.3.5 Operation
To operate with the machine
proceed as described below:
• Using the specific control, position the
chute and the deflector (fig. 1.G).
• To increase the length of the snow jet,
position the deflector upwards.
• To decrease the length of the snow jet,
position the deflector downwards.
• Set the gear depending on the
route and the depth of snow.
• Press the auger control (fig. 14.C)
to activate auger rotation.
• Press the forward control (fig. 14.D)
to activate traction.
NOTE Always use full throttle
when using the machine.
6.3.6 Steering
Steering is done differently depending
on the snow thrower model.
ST 526 S
Steering the machine in
the desired direction.
Steering is facilitated on models
with the "diff-lock release"
(see technical data table).
ST 627 S
Push the steering lever to the
right or left (fig. 14.C, fig 14.D)
in order to steer to the right or
left. (see paragraph 7.2).
6.3.7 Gear change
The gears are changed differently
depending on the snow thrower model.
ST 526 S
Gears are changed with
the machine stopped.
To change gear, proceed as follows:
• Stop the machine by releasing
• Move the gear stick to the
• Start operating as normal again.
IMPORTANT Changing gears
with the machine moving causes
damage to the gearbox.
ST 627 S
Gears are changed while moving.
To change gear, proceed as follows:
• During normal work, move
IMPORTANT It may be more
difficult to change gears when
the machine is at a stop.
6.4 STOP
To stop the machine, release the auger control
(fig. 14.C) and the forward control (fig. 14.D).
To turn off the machine, proceed in
one of the ways described:
• Remove and turn the safety key (fig. 15.A).
• Move the throttle (fig. 15.C)
to the stop position.
The fuel cock must always be closed
when the machine is not in use.
The engine may be very warm
immediately after it is shut off. Do not
touch the exhaust or adjacent parts.
This can cause burn injuries.
IMPORTANT If you need to leave
the machine unattended, always
remove the safety key (fig. 15.A).
6.5 ADVICE FOR OPERATION
• Snow is removed more easily when it is
still fresh. Pass back over the already
cleared zones to remove snow residue.
• If possible, clear the snow in the direction
of the wind. Check the distance and the
direction of the removed snow jet.
• In strong winds, lower the deflector to
direct the discharged snow towards the

the gear stick to the desired
position (fig. 12.A).
