• Top up if the level is lower than
the "MAX" mark (fig.17)
• For the correct replacement
procedure, see par. 7.3.2
Do not overfill as this could cause the
engine to overheat. If the oil level exceeds
the "MAX" mark, the oil must be drained
until the correct level is achieved.
NOTE For the type of oil to use,
see the "Technical Data Table".
7.3.2 Replacement
The oil may be very hot if removed
just after the engine has been switched
off. Consequently allow the engine to
cool down for a few minutes before
proceeding to drain off the oil.
Replace the engine oil based on the frequency
indicated in the "Maintenance Table". Change
the oil more frequently if the engine has
to operate in demanding conditions.
Proceed as follows:
1. Place the machine on a flat surface.
2. Place a suitable container
under the drain plug.
3. Remove the top-up cap (fig. 15.K)
4. Remove the drain cap (fig. 15.J)
5. Collect the oil in a suitable vessel.
6. Screw the oil drain plug back in.
7. Clean up any spills.
8. Fill with fresh oil. For the quantity of oil to
use, see the "Technical data table".
9. After filling up the oil, start the engine
and leave it to idle for 30 seconds.
10. Check there are no oil leaks.
11. Stop the engine. Wait 30 seconds and
check the oil level again. If necessary,
also see "check/top-up" (par. 7.3.1).
IMPORTANT Hand the spent
oil over to a disposal facility in
accordance with local provisions.

7.4 CLEANING

Carry out cleaning operations with the
machine switched off Do not try to remove
snow from the discharge without firstly:
• Releasing the auger control.
• Turning off the engine.
• Removing the ignition key.
Always clean the machine after use.
To clean the machine adhere to the
instructions provided below:
• Use the shovel (fig. 1.I) to clean the
discharge chute and for cleaning
accumulated snow off the machine.
• Clean the engine with a brush
and/or compressed air.
• Do not spray water directly onto the engine.
• After cleaning using water, start the
machine and auger to remove any
water which may otherwise end up in
the bearings and cause damage.
IMPORTANT Never use high-pressure water
jets. It could damage the electrical components.

7.5 SPARK PLUG

For spark plug operations, contact the
Dealer or Authorised Assistance Centre.
Consult the Maintenance Table and
the Problems Identification Table for
any intervention on the spark plug.

7.6 CARBURETTOR

The carburettor is pre-tuned by the
manufacturer. Consult the Problems
Identification Table to check when intervention
is required on the carburettor (chap. 12).

7.7 NUTS AND BOLTS

• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• At frequent intervals check all fasteners
on the discharge chute to ensure
they are securely tightened.

7.8 AUGER SHAFT

To facilitate the rotation of the auger, it is
recommended to grease the nipples (fig. 18.A)
of the auger shaft using a greasing gun.
To grease:
– Remove the cotter pins and
safety pins(fig. 18.B).
– Grease the nipples (fig. 18.A) and rotate
the auger on the shaft a few times to
allow the grease to flow inside the shaft.
– Replace the safety pins and
cotter pins. (fig. 18.B)
