Maintenance and Storage

Stop the engine and unplug the spark plug before any repairing or maintenance work is carried out.
Make sure that all nuts, bolts and screws are kept well tightened to keep
the Lawn Mower in a safe operating condition.
NEVER store the Lawn Mower with petrol in the tank or in an enclosed
area where petrol fumes could reach a strong heat source or a flame.
Allow the engine to cool down before you store your lawn mower in a
storage place.
In order to reduce any risk of fire, clean the lawn mower in particularly
the engine, the muffler, and the fuel tank. Suppress all grass traces,
leaves or excess of grease.
Check frequently the condition of the deflector and the grass catcher,
replace them if there is any damage.
If you have to drain oil from the tank before winter, do this operation outside.
Wear thick gloves before mounting or sharpening the blade. Be sure that the blade is always well balanced.
Check regularly the oil level, add oil or replace it if necessary.
Frequently check the lawn mower and make sure that all grass deposits are removed from beneath the deck.
Lubricate regularly the wheel axle and the bearing with grease.
Check blades often, in order to obtain clean work the blade should always be sharp and well balanced.
At regular intervals check and tighten all bolts and screws. Wear off or badly tightened nuts and bolts can
cause damages to the engine or to the frame.
If the blade hits violently an obstacle, stop the lawn mower and take your mower to an authorized service
centre.

Blade

The blade is made of pressed steel, in order to obtain a clean work, sharpen the blade frequently, about
every 25 hours of work. Be sure that the blade is always well balanced.
Introduce a small iron axle (2 or 3 mm of diameter) in the central hole of the blade:
It should stay horizontal. If the blade does not stay horizontal, balance it by taking off some of the metal on
the side which is down.
To remove the blade, unscrew the screw, check the blade support and change all spare parts if they are worn
out or damaged.
To sharpen the blade, place it in a vice and file the cutting edge evenly, checking its balance.
When reassembling the blade, make sure that the cutting edges face in the direction of the engine's rotation.
The blade screw must be torque to
3.7Kg*m/s2(37Nm) with a dynamometric tool.
Use only original spare parts. Spare parts of bad quality can cause damages to your lawn mower and
compromise your safety.
