7. ROUTINE MAINTENANCE
7.1 GENERAL INFORMATION
The safety regulations to follow are described in
chap. 2. Strictly comply with these indications to avoid
serious risks or dangers.
Before conducting any inspections, cleaning or
maintenance/adjustment interventions on the machine:
• Stop the machine.
• Make sure that all moving parts have
come to a complete stop.
• Wait until the engine is sufficiently cold.
• Remove the spark plug cap (Fig.21.0).
• Read the relevant instructions.
• Use suitable clothing, protective
gloves and goggles.
• The frequency and types of maintenance are
summarised in the "Maintenance Table". The
table will help you maintain your machine's
safety and performance. It summarises the main
interventions to be made and the frequency
applicable to each of them. Carry out the relevant
intervention according to the first deadline.
• The use of non-genuine and/or incorrectly
assembled spare parts and attachments could
adversely affect machine operation and safety. The
manufacturer shall decline all liability in the event
of injuries or damages caused by such parts.
• Genuine spare parts are supplied by authorised
assistance workshops and dealers.
IMPORTANT Any maintenance and adjustment
operations not described in this manual must be carried
out by your dealer or Authorised Service Centre.
7.2 REFUELLING
Place the machine in a stable horizontal
position on the ground.
Refuelling shall take place with the machine
switched off and the spark plug cable disconnected.
Continue to refuel following the instructions and
precautions provided in the engine manual.
IMPORTANT Do not drip petrol onto the plastic parts of
the engine or the machine to prevent damaging them and
remove all traces of spilt petrol immediately. The warranty
does not cover damage to plastic parts caused by petrol.
NOTE Fuel is perishable and should not remain
in the tank for more than 30 days. Before storing for
a long period, fill the tank with a sufficient amount
of fuel to reach final destination (chap. 9).
7.3 CHECK/TOP-UP ENGINE OIL
Continue to check/top-up the engine oil
following the instructions and precautions
provided in the engine manual.
To ensure that the machine will function properly
over time, it is highly recommended to change
the engine oil regularly, following the timing
indicated in the engine's Instruction Manual.
Remember to top-up with oil before
using the machine again.
7.4 CLEANING
Clean thoroughly following the instructions
below every time it is used.
7.4.1 Cleaning the machine
• Always make sure the air intakes are free of debris.
• Do not use aggressive liquids to clean the chassis.
• To reduce fire hazards, keep the lawnmower
and, in particular, the engine free of
grass, leaves, or excessive grease.
• Wash the machine thoroughly with water
after each cutting operation.
7.4.2 Cleaning the cutting-means assembly
• Remove grass debris and mud accumulated in
the chassis to prevent it from drying and causing
problems the next time the lawnmower is used.
• If accessing the lower part is necessary, only tilt
the machine on the side indicated in the engine
manual, following the relevant instructions,
making sure that the machine is perfectly stable
before performing any interventions.
For side and rear discharge: if fitted,
remove the discharge chute.
To wash the inside of the cutting-means
assembly, proceed as follows:
1. Remove the grass catcher.
2. Connect the water hose to the specific
attachment (Fig.20.A).
3. Lower the cutting height as far as possible.
4. Always stand behind the lawnmower handle.
5. Start the engine.
Paint on internal chassis parts may come off over
time due to the abrasive action of cut grass; if this
happens, promptly touch-up paint with rust-proof paint
to prevent rusting that could corrode the metal.
7.4.3 Cleaning the grass catcher
1. Empty the grass catcher;
2. Shake it to remove grass cuttings and soil residue;
Wash and rinse it, then place it
3.
where it can dry quickly.
7.5 NUTS AND BOLTS
Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
