7.3 CHECK/TOP-UP ENGINE OIL
Always check the oil level before use.
NOTE The machine is delivered
to the user without engine oil.
7.3.1 Check/top-up
Procedure:
• Make sure that the machine is level
before performing the check.
• Clean around the plug (fig. 15.F).
Unscrew and remove it. Clean the rod.
• Insert the rod completely, without
screwing it in position.
• Remove the rod again. Check the oil level.
• Unscrew the oil filler plug (fig. 15.K).
• If the level is low, top up to
the "L" 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 "H" mark, drain
until the correct level is achieved.
NOTE For the oil type to be used,
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 at the intervals
indicated in the "Maintenance table".
Replace the oil more often if the engine
must operate in difficult conditions.
Proceed as follows:
1. Place the machine on a flat surface.
2. Place a collection container
next to the discharge pipe.
3. Remove the filler plug (fig. 15.K).
4. Remove the discharge plug (fig. 15.J).
5. Collect the oil in a suitable vessel.
6. Screw the oil discharge plug.
7. Clean up any spills.
8. Fill with new oil. For the required oil
quantity, see the "Technical data table".
9. Upon each refuelling, start the engine
and let it run for at least 30 seconds.
10. Check that there are no oil leakages.
11. Stop the engine. Wait for 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
Perform the cleaning operations with
the machine switched off. Do not attempt
to remove the snow from the discharge
before having first performed the following:
• Release the auger control.
• Switch off the engine.
• Remove the ignition key.
Always clean the machine after use. Observe
the following instructions for cleaning:
• Use the paddle (fig. 1.I) to clean the discharge
chute and the machine from snow residues.
• Clean the engine with a brush
and/or compressed air.
• Do no spray water directly on the engine.
• After cleaning with water, start the
machine and the auger to remove the
water that may otherwise infiltrate in
the bearings and cause damages.
IMPORTANT Never use pressurised water.
It may damage the electrical components.
7.5 SPARK PLUG
For operations to be performed on the spark
plug, refer to a Dealer or an Authorised
Service Centre. Refer to the maintenance
table and problem identification table for
interventions concerning the spark plug.
7.6 CARBURETTOR
The carburettor is pre-adjusted by the
manufacturer. Refer to the problem identification
table to check when interventions are
required on the carburettor (cap. 12).
