MAINTENANCE
Oil (daily)
Remove the dipstick N and check that the oil level
reaches the full mark. If necessary, top off with fresh oil.
To obtain the correct oil level, the machine must be
level. See engine manufacturer’s manual for proper oil
viscosity and grade. DO NOT OVER FILL!
AFTER THE FIRST 5 WORKING HOURS
While the engine is warm, remove the drain plug T and
drain the crankcase. Replace oil filter U. Clean and
replace the plug. Fill the crankcase through the filler
hole with fresh oil to the full mark. See engine
manufacturers manuals for oil and filter change
intervals.
Cooling Fins and Air Intake screen (daily)
Ensure that the cooling fins and air intake screen W
are cleaned daily. Continued operation with a
clogged cooling system will cause severe
overheating and result in engine damage.
Air Cleaner
Dual element air cleaners have a paper air cleaner
element with an oiled, foam precleaner element on
the dirty side of the paper element. Both should be
inspected regularly and maintained.
Clean and re-oil precleaner element every 25 hours
(more often under dusty conditions).
1. Disassemble air cleaner cover.
2. Remove precleaner by sliding it off the paper
cartridge.
3. Wash precleaner in kerosene or liquid detergent
and water.
4. Wrap precleaner in cloth and squeeze to remove
cleaner.
5. Saturate precleaner in engine oil. Squeeze to
remove excess oil.
6. Re-install precleaner over paper cartridge.
Reassemble air cleaner components and screw
assembly down tight.
Every 100 hours (more often under very dusty or
dirty conditions), check the paper cartridge.
– Clean by tapping gently.
– Do not wash the cartridge or use compressed air
– Replace when cartridge is dirty, bent or
damaged.
