tine holders. Please follow this
maintenance recommendation, as
debris can cause premature wear to
the tine shaft and its oil seals.

TIRE AND WHEEL MAINTENANCE
Check tire air pressure every 30
operating hours. The recom­
mended pressure for tilling is 10-
to-20 psi (pounds per square inch).
Both tires should be inflated
equally. (Unequal pressure can
cause the tiller to pull to one side.)
A
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before removing
or replacing the wheels.
Removing the Wheels
Each wheel is secured by a roll
(spirol) pin that passes through the
wheel hub and the wheel shaft.
Drive the roll pin out to remove a
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 Speed Lever to
either SLOW or FAST position to
prevent the wheels from turning.
3. Use a 5/16" drift pin (or a blunt
point 16-penny nail) to drive the
roll pin free.
A WARNING
Wear safety goggles when
driving the roll pin into or
from the wheel hub to protect
your eyes from the possibility
of flying metal particles.
removal instructions (see previous
page). After cleaning away any
debris and removing old grease
from the tine shaft, apply fresh
grease to the tine shaft.
ENGINE OIL MAINTENANCE
Change engine oil after first five
(5) hours of new operation. There­
after, change the oil every ten (10)
operating hours. This may be more
often than your engine manufac­
turer literature recommends, how­
ever your tiller may be operating in
dirty or very dusty conditions.
Follow the engine manufac­
turer’s literature for specific oil
changing procedures, quantity of
oil, and particular grade and vis­
cosity of oil to use in your engine.
Locations to check the oil level and
to drain the oil are shown at right.
Note that there are two oil fill
plugs (one on each side) on the
Briggs & Stratton engines.
