MAINTENANCE
A
WARNING: Disconnect the spark piug
wire and ground it against the engine
before performing any repairs o' mainte­
nance.
IMPORTANT: If for any reason the tines are removed
from the tiller, be certain the tines are reassrsmbled so
that the sharp edge of the tines enter the soil first.
Refer to item number one under “Operation. ’
TROUBLE SHOOTING
Refer to page 15 of this manual for troubk shooting
information.
ENGINE
Refer to the separate engine manual for all engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cieaner every 25 hours under n Drmal con­
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaners should be ser­
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom­
mended at the start of each tilling season; check
engine manual for correct plug type and gap specifi­
cations.
CLEANING THE TINE AREA
Clean the underside of the tine shield after each use.
The dirt washes off the tines easier if washed immedi­
ately instead of after if dries.
TIRES
Recommended operating tire pressure is approxi­
mately 12 p.s.i. (check sidewall of tire for tire manu­
facturer’s recommended pressure). Maximum tire
pressure under any circumstances is 30 p.s.i. Equal
tire pressure should be maintained on both tires.
When installing a tire to the rim, be certain rim is
clean and free of rust. Lubricate both the tire and rim
generously. Never inflate to over 30 p.s.i. to seat
beads.
A
WARNING: Excessive pressure (over 30
p.s.i.) when seating beads may cause
tire/rim assembiy to burst with force suf­
ficient to cause serious injury.
BELT REPLACEMENT
Your tiller has been engineered with belts made of
special material (Kevlar Tensile) for longer life and
better performance. They should not be replaced with
an off-the-shelf belt.
If belt replacement is required, order belt or belts by
part number from your nearest authorized dealer.
1. Remove belt cover by removing the four self-tap­
ping screws. See figure 24.
