TILLER LUBRICATION
After every 10 operating hours, oil or
grease the lubrication points shown in
Figure5-1 and described below.
Useclean lubricating oil (#30weight motor
oil is suitable) and cleangeneralpurpose
grease (greasecontaining a metallubricant
is preferred, if available).
• Removethe wheels,cleanthe wheel shaft
(A, Fig. 5-1) and applya thin coating of
grease to the wheel shaft.
• Greasethe back, front and sides of the
depth regulator lever (B, Fig.5-1).
• Removethe tines andclean thetine shaft
(C,Fig.5-1). Usea file or sandpaperto gen-
tly removeany rust, burrs or rough spots
(especiallyaround holes in shaft). Apply
grease to ends of shaft before installing
tines.
• Oil the threads on the handlebar height
adjustment screws and the handlebar
attaching screws (D, Fig.5-1).

CHECKFOROIL LEAKS
Beforeeach use,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 off
leak can result in severetransmission
damage!
17
If acover is leaking,check for loose
screws. If the screws are tight, a new
gasket or oil seal may be required.
If the leak is from around a shaft andoil
seal, the oil seal probably needsto be
replaced.Seeyour authorized dealeror
contact the factory for service or advice.
IMPORTANT:Neveroperatethe tiller if
the transmission is low on oil. Checkthe
oil level after every 30 hours of
operation and wheneverthere is anyoil
leakage.
CHECKHARDWARE
Checkfor loose or missing hardwareaf-
ter every 10 operatinghours andtighten
or replace(as needed)beforereusing
tiller
Besure to checkthe screws underneath
the tiller hoodthat securethe transmis-
sion coverandthe DepthRegulatorLever
to the transmission.
CHECKTIRE PRESSURE
(Modelswith pneumatictires)
Checkthe air pressurein both tires. The
air pressure should bebetween 15 PSi
and 20 PSi (pounds per squareinch).
Keepboth tires equally inflated to help
prevent machinefrom pulling to one
side.
TRANSMISSION
GEAROIL SERVICE
Checkthe transmission gear oil level
after every 30 hours of operation or
wheneveryou notice any oil leak.Oper-
ating the tiller when the transmission is
low on oil can result in severedamage.
A. To Check theTransmission
GearOil Level:
1. Checkthe gear oil level when the
transmission is cool. Gearoil will
expand in warm operatingtemperatures
and this expansionwill provide an incor-
rect oil level reading.
2. With the tiller onlevelground, pull the
Depth Regulator Leverall the way up.
3. Removethe oil fill plug (A, Fig. 5-2)
from the transmission housing andlook
inside the oil fill hole to locatethe main
drive shaft situated below the hole.
