Translation of the Original Instructions
MAINTENANCE AND LUBRICATION
CAUTION!
- Disconnect the plug before performing any cleaning, maintenance or repair operation.
Always wear suitable clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always
remember to use suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without
safety locks or supports, never leave it unguarded in places where inexperienced people
and children could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant
product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
RUNNING-IN: change the engine oil after the first twenty working hours.
ENGINE – Follow the instructions outlined in the engine's manual. In general users are advised to
check the oil level every 8 working hours and to change it every 100 hours. Always use 15W40.
Check the air filter oil level every 8 working hours or more often in very dusty conditions. Top up
with the same oil as for the engine (see engine handbook). On versions with dry filter, replace the
cartridge if clogged (do not clean with compressed air jets).
GEARBOX – Check the oil level every 50 working hours by removing the cap and checking with
the machine horizontal the oil reaches between the two notches. If necessary add MP 80 W/90
(API GL5 US-MIL-L-2105D) oil. Change the oil once a year.
ROTARY TILLER – Check the oil level every 50 hours by removing the plug; the oil must almost fill
the rotary tiller box. If necessary add the same oil as for the gearbox (fig. 4D, n. 3).
TIPS FOR EFFICIENT USE
1) Always release the red clutch lever (fig. 3A, n. 1) before shifting form the forward gear to the
reverse gear and vice-versa.
2) Always release the red clutch lever (fig. 3A, n. 1) before engaging the PTO.
3) Never leave the machine exposed to bad weather condition.
4) Keep cables and lever always clean from dust and residues.
5) Never force the reverse gear: If the gear does not engage immediately, do not force the lever
but press and release it repeatedly until the gear engages (fig. 3A, n. 13).
6) Never strain the engine: if smoke comes out of the exhaust, slow down.
7) Even impossible ground can be tilled, but the machine must be well run-in first.
8) Frequently check the tyre pressure.
9) When fitting the implements (e.g. rotary tiller) take care not to damage the centring device of the
walking tractor gearbox (fig. 4F).
END OF SEASON MAINTENANCE
Carefully wash the walking tractor, replace the oil in engine and the gearbox oil, clean the air filter.
Sharpen the hoes and grease them. Replace them if worn.
IMPORTANT: The hoes of Grillo
walking tractors are made of a special steel subjected to heat treatments. Never weld the
hoes if broken or cracked, because they could break and be flung away becoming therefore
highly dangerous for people and objects around.
