MDR-9DYE — MAINTENANCE
ENGINE OIL REPLACEMENT
1. Replace engine oil in the first 25 hours of operation and
every 50 to 100 hours afterwards.
2. Oil may be drained more easily when it is warm after
operation (For more details, see separate engine Owner's
Manual).
AIR FILTER
1. The air filter element should be cleaned because a clogged
air cleaner can cause poor engine starting, lack of power
and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 25) 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.

CHECKING THE CHAINS

chain if necessary (Figure 26. 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 27). Chain tension should be
adjusted every 50 hours of operation.

VIBRATION CLUTCH ADJUSTMENT
1. Remove the protective cover from the clutch by removing
the 4 allen screws.
2. Pull out the stop key and turn to the release position (Figure
29).
3. Viewing the clutch from the shifter-pulley side: if the clutch
nut is turned to the right, the clearance between the adjusting
and pressure plate decreases as the amount of torque
increases. Normal adjustment is from 1 to 2 notches.
4. Make sure that the shifting lever is not too stiff. Lever should
engage with moderate pressure.
5. After adjustment, return the stop key to the locked position.
