OPERATING SUGGESTIONS

Snow removal is more efficient when it is still fresh. Go again through the cleared areas to remove snow residues
If possible, eject the snow in the wind direction. Check the distance and the direction of the jet of ejected snow.
In case of strong winds, lower the deflector so as to guide the discharged snow on the ground, reducing thus the possibility of the snow being carried away in improper areas.
Upon finishing the work, leave the machine running for a few minutes, to avoid the formation of ice in the ejection outlet.
Always maintain a speed adequate to the snow conditions and adjust it so that the snow is ejected at a constant flow.
Reduce the engine rotations before stopping it.

AFTER USE

Clean (par. 7.4).
Move all controls forward and backward several times.

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”.

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:

Place the machine on a flat surface.
Place a collection container next to the discharge pipe.
Remove the filler plug (fig. 15.K).
Remove the discharge plug (fig. 15.J).
Collect the oil in a suitable vessel.
Screw the oil discharge plug.
Clean up any spills.
Fill with new oil. For the required oil quantity, see the “Technical data table”.
pon each refuelling, start the engine and let it run for at least 30 seconds.
Check that there are no oil leakages.
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

CLEANING
