MAINTENANCE
Read the safety instructions
Should the number of working hours that the
machine is in use during the indicated period
exceed the number quoted in brackets, then use
the recommended ‘working hour’ guide as the
maintenance schedule.
DAILY (EVERY 8 WORKING HOURS)
COOLING FINS AND AIR INTAKE
Check to ensure that the air intake (B Fig. 26) and
cooling fins (A Fig. 27) are kept free of all grass
clippings and debris. This is essential to allow the
free passage of air so that the cooling system
functions correctly. A blocked cooling system will
result in overheating and possible engine damage.
Clean more frequently under adverse conditions.
WEEKLY (EVERY 50 WORKING
HOURS)
AIR CLEANER (FIG. 28)
Clean air cleaner element
