TILLERLUBRICATION
After every 10 Operatinghours, oil or
grease the lubrication points shown in
Figure5-1 and described belOW,
Useclean lubricating oil (#30weight motor
oil is suitable) and clean generalpurpose
grease(greasecontaining a metallubricant
is preferred, if available).
• Removethewheels,cleanthe wheel shaft
(A, Fig.5-1) and apply a thin coating of
greaseto the wheel shaft,
• Greasethe back, front and sides of the
depth regulator lever (B, Fig. 5-1).
• Removethe tines andcleanthetine shaft
(C, Fig.5-1). Use a file or sandpaperto
gently remove any rust, burrs or rough
spots (especiallyaround holes in shaft).
Apply greaseto ends of shaft before install-
If a cover is leaking,check for loose
screws. If the screws aretight, 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 authorizeddealeror
contact the factory for service or advice.
IMPORTANT:Neveroperate the tiller if
the transmission is low on oil. Check
the oil level after every30 hours of
operation and wheneverthere is any oil
leakage.

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 causefor alarm. How-
ever,if the oil drips overnight, then imme-
diate attention is needed. Ignoring an oil
leak can result in severe transmission
Checkthe transmission gear oil level
after every 30 hours of operation or
wheneveryou noticeany oil leak. Oper-
ating the tiller when the transmission is
low on oil can result in severedamage.
A. ToChecktheTransmission
GearOil Level:
1. Checkthe gear oil levelwhen the
transmission is cool. Gearoil will
expand in warm operating temperatures
andthis expansionwill provide an incor-
rect oil level reading.
2. With the tiller onlevelground, pullthe
Depth RegulatorLever all the way up.
3. Removethe oil fill plug (A, Fig.5-2)
from the transmission housing and look
