is preferred, if available).
•Removethewheels,clean thewheelshaft
(A,Fig. 5-1) and apply a thin coating of
greaseto the wheel shaft,
• Greasethe back,front and sides of the

Beforeeachuse,checkthe tiller for signsof
anoil leak-- usuallya dirty, oilyaccumu-
lationeither on the unit or on the floor.
A little seepagearound a cover oran oil
sealis usually not acausefor alarm. How-
ever,if the oildrips overnight, then imme-
diateattention is needed. Ignoring an oil
leakcan result insevere transmission
Checkthetransmission gearoil level
after every 30 hours of operationor
wheneveryou notice any oil leak. Oper-
atingthe tiller whenthe transmission is
lowon oil can result in severe damage.
A. ToChecktheTransmission
GearOil Level:
1. Checkthe gear oil levelwhen the
transmission is cool. Gearoil will
expandin warm operating temperatures
andthis expansion will provide an incor-
rectoil levelreading.
2.With the tiller onlevelground, pull the
DepthRegulator Leverall the way up.
