Section5: Maintenance
_ efore inspecting, cleaning or servicingthe machine, shutoff engine, wait for all movingpartsto come
to a completestop, disconnectsparkplug wire and move wire away from spark plug. Remove ignition
key, if soequipped.
Failureto follow these instructionscanresult in seriouspersonalinjuryor propertydamage.
Tine Shaft Maintenance
After every 10 operating hours, remove
the left- and right-side Bolo Tine holders
and clear away dirt and debris that have
accumulated on the Oneshaft or inside
the Oneholders. Pleasefollow this main-
tenancerecommendation, as debris can
cause prematurewear to the Oneshaft
and its oil seals. Referto the previous
tine holder removal instructions. After
cleaning away any debris and removing
old greasefrom the tine shaft, apply fresh
grease to the tine shaft.
Tire and Wheel Maintenance
Checktire air pressure every 30 operating
hours. The recommended pressurefor
tilling is 104o-20 psi (pounds per square
inch). Both tires should be inflated
equally. (Unequal pressurecan causethe
tiller to pull to one side.)
Removing the Wheels
Eachwheel is secured by a roll (spirol)
pin thatpassesthrough the wheel hub
and the wheel shaft. Drive the roll pin out
to removea wheel.
1. Prop the transmission up with a sturdy
block to raise the wheel you want to
remove off the ground.
2. Move the Wheel SpeedLever to either
SLOWor FASTposition to prevent the
wheels from turning.
3. Use a5/16" drift pin (or a blunt point
16-penny nail) to drive the roll pin free.
Wear safety goggleswhen driving the
roll pin into or from the wheel hub to
protectyour eyesfrom the possibilityof
flying metal particles.
Engine Oil Maintenance
Checkthe engine oil level before starting
the engineeach day and after each 5
hours of continuous operation. Running
the enginewhen it is low on oil will
quickly ruin the engine.
It is recommended that you changethe oil
everyten (I0) operating hours and even
sooner when operating in extremelydirty
or dusty conditions. Referto the separate
EngineOwner's Manualfor detailed
service instructions.
Air Cleaner Maintenance
The engine is equipped with a dual
element air cleanerthat filters the air
twice before it enters the carburetor to
mix with the fuel.
The engineair cleaner filters dirt and dust
out of the air before it entersthe carbure-
tor. Operating the enginewith a dirty,
clogged air filter can cause poor perfor-
manceand damage to the engine. Never
operate the engine without the air cleaner
installed. Inspectand servicethe air
cleaner more often if operating in very
dusty or dirty conditions.
It is critical that the filters be kept clean
and properly installed at all times. See
the location of the air cleanerassembly on
your engine by referring to Figure5-39 or
Figure 5-40.
Referto the engine manufacturer's litera-
ture supplied with your tiller for complete
air cleaner service and maintenance infor-
mation.
Throttle Cable Maintenance
The throttle lever settings arefactory-
adjusted, so unnecessaryadjustments
should not bemade. However,if the
enginedoes not start or stop, or respond
immediately to various throttle lever
settings, then adjustments may be
necessary. Pleaserefer to the engine
manufacturer literature supplied with your
tiller for specific adjustment instructions.
Ignition System Maintenance
Your engine is equippedwith electronic
ignition. It does not havea condenser or
points, so there is no need to perform any
regular tune-up maintenance on this
system other than adjusting or replacing
the spark plug.
Spark Plug Maintenance
The spark plug must be in good condition
for proper engineoperation. Remove and
inspect the plug every 50 operating hours
or annually, whichever occurs first.
The correct electrodegap is .030". Check
the gap with a feeler gauge. Do not use a
spark plug if the porcelain is cracked, the
electrodesare pitted or burned, or if other
visible damage is present.
NOTE: Do not wire brush or sandblast the
spark plug to clean it - loose particles
can enter the engine, causing damage!
To replacethe plug, first tighten it
securely by hand, then use a spark plug
wrench to tighten the plug an extra 114
turn.
Battery Care and Maintenance
Battery Care in Service
I. Everymonth or every ten (10)
operating hours, whichever comes first,
checkthe level of electrolyte solution in
the battery cells:
a. If battery casehas UPPERand
LOWERlevel lines on it, solution
should be maintained at the UPPER
level line.
b. If the battery does not havelevel
lines on case, maintain solution
levelat lowest part of the filler well
within eachcell.
NOTE: Use only distilled or demineralized
water to refill eachbattery cell.
c. After filling, replace battery caps
securely,then wash off any spilled
solution with baking soda and water
mixture.
d. Run engineoutdoors for about 20
minutes (at 3/4 throttle) to help
recharge. For safety, do not leave
the tiller unattendedwhile the
engine is running.
