14 – MAINTENANCE and LUBRICATION
To optimise the efficiency of the machine it is necessary to maintain the machine correctly and to ensure
the engine is fully lubricated. The machine is normally supplied packed without oil in the engine, as clearly
indicated on the label attached to the engine.
ENGINE.
For suggestions, utilisation and maintenance of the engine strictly follow the instructions
indicated in the proper book “
ENGINE UTILIZATION AND MAINTENANCE
”. It is necessary to check
the oil level every 5 working hours and replace it every 50 hours. Use SAE 40 oil in summer and SAE 20 oil
in winter. The first oil change must be done after 10 working hours.
Check the air filter is clean, especially if the machine is to work in barren or dusty conditions.
GEAR REDUCTION.
Check the oil level every 50 working hours by taking off the plug on the gear box
case and keeping the machine in a horizontal position. If necessary, add oil SAE 80-90. It’s advisable to
change the oil at least once a year.
CUTTER BAR
. Before starting work, check all the screws are well tightened .
Every 4 working hours grease the internal blade support.
Every 10 working hours grease the bush of the eccentric gear.
Every 20 working hours grease the connection between the cutter bar and the machine.
ROTARY TILLER
Check all the screws of the blades are well tightened, change the oil in the rotary tiller
body minimum once a year. Capacity oil cl 250.
Before leaving the machine idle for a long time, it is necessary:
- to wash it outside, to replace the oil in the engine and gear box,
- to empty and to clean the fuel tank and to clean or replace the air filter,
- to oil and to grease all the joints and mechanisms,
- to replace or to repair the damaged parts,
- to lubricate the cylinder with engine oil through the spark plug hole by letting the piston run several times,
by pulling the rope of the starter,
- place the machine in a sheltered place and with the wheels on wooden tables or, even better, keeping them
away from the floor.
15 – TROUBLES and SOLUTIONS
Few problems can occur that cannot be solved directly by the operator.
ENGINE
- The engine does not start; check that:
- the petrol tap is open
- if the engine is cold the starter is pulled
- the petrol is reaching the carburettor
- that the breather hole on the fuel tank is not obstructed
- the carburettor jets are open, if not clean them with an air jet
- there is a spark at the spark plug, to check this, unscrew the spark plug; connect it again to the wire, lean
the metal part of the spark plug against the engine cylinder and make the pulley turn as for starting. If
between the electrodes you do not see any sparks, check the cable joints, if there is not a problem there then
replace the spark plug with another one of the same type. If this still does not solve the problem then there is
probably a fault in the electrical installation ( sparking plug points, condenser, coil, etc.)
In this case it is advisable to contact your nearest service assistant.
