Maintenance & Adjustments
WARNING!

maintenance or repairs.
Maintenance
Engine
Refer to the separate Engine Operator's Manual for engine
maintenance instructions.
Tires
Recommended operating tire pressure is approximately 20 p.s.i.
on 16" tires. (Check the sidewall of the tire for the manufacturer's
recommended pressure). Maximum tire pressure under any
circumstances is 30 p.s.i. Equal tire pressure should be maintained
on both tires.
WARNING!
seating beads may cause the tire/rim assembly to
burst with force sufficient to cause serious injury.
Tines
Use the Smart Jet™ to rinse dirt from the tines and the tine shield
and prevent the buildup of corrosive chemicals. Complete the
following steps right after tilling to prevent dirt from hardening
and becoming more difficult to remove:
1.
Move the tiller to a level, clear spot on your lawn, near
enough for your garden hose to reach.
1.
Disengage the tines and stop the engine.
2.
Thread the hose coupler onto the end of your garden hose.
3.
Attach the hose coupler to the water port on the top of
your tine shield. See Figure 6-1.

While standing in the operator's position behind the tiller,
start the engine and place the throttle in the FAST
position.
8.
Engage the tines.
9.
Remain in the operator's position with the tines engaged
for a minimum of two minutes, allowing the underside of
the tine shield to thoroughly rinse.
10.
Disengage the tines.
11.
Place the throttle in the STOP
tractor's engine off.
12.
Turn the water off and detach the hose coupler from the
water port on your tine shield.
13.
After cleaning your tines and tine shield with the Smart Jet™
system, return to the operator's position and engage the
tines. Keep the tines engaged for a minimum of two minutes,
allowing the tines to thoroughly dry.
Transmission Gear Oil
Check the transmission gear oil after every 30 hours of operation
or whenever you notice any oil leak. Operating the tiller when
the transmission is low on oil can result in severe damage.
To Check the Transmission Gear Oil Level:
1.
Check the gear oil level when the transmission is cool. Gear
oil will expand in warm operating temperatures and this
expansion will provide an incorrect oil level reading.
2.
With the tiller on level ground, pull the depth adjustment
lever all the way up.
3.
Remove the oil fill plug from the transmission housing and
look inside the oil fill hole to locate the main drive shaft
situated below the hole. See Figure 6-2.
