MAINTENANCE
Maintenance and Storage
Regular maintenance is essential for keeping the safety level and original performance of the machine.
IMPORTANT
• 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.
• To reduce any risk of fire, keep the engine, exhaust
silencer, battery compartment and fuel storage
area free of grass, leaves, or excessive grease.
• Check frequently the condition of the deflector
and the grass catcher, replace them if there is any
damage.
• If the fuel tank has to be drained, this should be
done outdoors and when the engine is cool.
• Wear thick gloves before mounting or sharpening
the blade.
• Check blades often, in order to obtain clean
work the blade should always be sharp and 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.
• If the blade hits violently an obstacle, stop the
Lawn Mower and take your Lawn Mower to an
authorized service centre.
Blade
• Tilt the Lawn Mower to the left, so the air cleaner
side is up. This will help to prevent fuel leakage
and hard starting.
• Inspect the blade for damage, cracks and excessive
rust or corrosion.
• A dull blade can be sharpened, but a blade that
is excessively worn, bent, cracked, or otherwise
damaged must be replaced.
• A torque wrench must always be used when
installing the blade.
• Check that the blade bolts are tight.
Removal and Installation
• If you remove the blade for sharpening or
replacement, you will need a torque wrench for
installation. Wear heavy gloves to protect your
hands.
• Remove the bolt with a socket wrench. Use a
wooden block to prevent the blade from turning
when removing the bolt. Then remove the blade.
• Install the blade using the blade bolt and special
washers. Be sure to install the special washers with
the concave side toward the blade and the convex
side toward the bolt.
• Tighten the blade bolt with a torque wrench. Use
a wooden block to prevent the blade from turning
when tightening the bolt.
