TILLER LUBRICATION
After every 10 operating hours, oil or
greasethe lubrication points shown in
Figure5-1 and described below.
Usecleanlubricating oil (#30weight motor
oil is suitable) and cleangeneralpurpose
grease(greasecontaining a metallubricant
is preferred, if available).
• Removethe wheels,cleanthe wheelshaft
(A,Fig. 5-1) and apply a thin coating of
greaseto the wheelshaft.
• Greasethe back,front and sides of the
depthregulator 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
greaseto ends of shaft beforeinstalling
tines.
• Oil thethreads on the handlebar height
adjustment screws and the handlebar

CHECKFOR OIL LEAKS
Beforeeachuse,checkthe tiller for signs of
an oil leak-- usually a dirty, oily accumu-
lation eitheron the unit or on the floor.
A little seepagearound a cover or an oil
sealis usually not a causefor alarm. How-
ever,if the oil drips overnight, then imme-
diateattention is needed.Ignoring an oil
leakcanresult in severetransmission
damage!
17
If acover is leaking,check for loose
screws. If the screws aretight, a new
gasket or oil seal may be required.
If the leakisfrom around a shaftand oil
seal, the oil sealprobably needsto be
replaced.Seeyour authorized dealeror
contact the factory for serviceor advice.
IMPORTANT:Neveroperatethe tiller if
thetransmission islow on oil.Checkthe
oil levelafter every 30 hours of
operationand wheneverthere is anyoil
leakage.
CHECKHARDWARE
Checkfor loose or missing hardwareaf-
ter every 10 operatinghours andtighten
or replace(asneeded)before reusing
tiller
Besure to checkthe screws underneath
thetiller hoodthat securethe transmis-
sioncoverandtheDepthRegulatorLever
to thetransmission.
CHECKTIRE PRESSURE
(Models with pneumatictires)
Checkthe air pressurein both tires. The
air pressure should be between 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 operationor
wheneveryou notice anyoil leak.Oper-
ating thetiller when thetransmission is
low on oil can result in severedamage.
A. To Checkthe Transmission
GearOil Level:
1. Checkthe gear oil levelwhenthe
transmission is cool. Gearoil will
expandin warm operatingtemperatures
and this expansionwill providean incor-
rect oil level reading.
2. With thetiller onlevelground, pullthe
Depth Regulator Leverall the way up.
3. Removethe oil fill plug (A, Fig. 5-2)
from thetransmission housingandlook
insidethe oil fill hole to locatethe main
driveshaft situated belowthe hole.
