CLEANING OR CHANGING ENGINE AIR FILTER
If engine is operating in very dusty and dry grass conditions.
A clogged air filter will result in high fuel consumption, loss
of power and excessive carbon buildup in the combustion
chamber. Clean air filter daily. Remember if operating in dusty
conditions, check the rubber bellows on the air blockage
indicator several times a day.
CAUTION :
TESTING ENGINEAAIR FILTER BLOCKAGE INDICATOR
To test the air cleaner blockage indicator (Figure 28) run the
engine at full speed for a short time. If the rubber bellows is
pulled inwards (down), and the green rubber band cannot be
seen, this implies that maintenance work is required on the
air cleaner. Clean or replace air cleaner.
Figure 28. Air Filter Blockage Indicator
To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 29), remove the cover and take out air
filter cartridge. If only cleaning of the air filter is desired blow
through the air filter cartridge from the inside, moving a jet
of dry compressed air up and down until all dust is removed.
DO NOT blow high pressure, high velocity
compressed air thru the air filter cartridge. The
high velocity air will damage the filter, which
will then allow contaminates to pass into the
engine.

CHECKING THE CHAINS
1. Take off the checking cover on roller and coat grease on the
chain if necessary (Figure 30). The chain should be lightly
lubricated with motor oil.
2. Check the chain tension and if loose, adjust the chain tension
with the tightener (Figure 31). Chain tension should be
adjusted every 50 hours of operation.
