If a cover is leaking, checkfor loose
screws. If the screws are tight, a new
gasket or oi! seal may be required.
If the leak is from around a shaft and oil
seal, the oil seal probably needsto be
replaced. Seeyour authorized dealer or
contact the factory for service or advice.
IMPORTANT:Neveroperate the tiller if
the transmission is low on oil. Check
the oil level after every 30 hours of
operation and whenever there is any oil
leakage.
CHECK HARDWARE
Checkfor loose or missing hardwareaf-
ter every 10 operatinghours and tighten

CHECK TIRE PRESSURE
(Models with pneumatic tires)
Checkthe air pressure in both tires. The
air pressure should be between 15 PSI
and 20 PSI(pounds per square inch).
Keep both tires equally inflated to help
prevent machine from pulling to one
side.

CHECKFOROILLEAKS
Beforeeachuse, checkthe tiller for signs of
an oil leak-- usually a dirty, oily accumu-
lation either on the unit or on the floor.
A little seepagearound a cover or an oil
seal is usually not a cause for alarm. How-
ever, if the oil drips overnight, then imme-
diate attention is needed.Ignoring an oil
Checkthe transmission gear oil level
after every 30 hours of operation or
whenever you notice any oil leak. Oper-
ating the tiller when the transmission is
low on oil can result in severe damage.
A. To Checkthe Transmission
Gear Oil Level:
1. Checkthe gear oil level when the
transmission is cool. Gear oil will
expand in warm operating temperatures
and this expansion will provide an incor-
rect oil level reading.
2. With the tiller on levelground, pull the
Depth Regulator Lever all the way up.
