4. Position the loose end of the hose forward and down
in front of the right side transmission so that it can
drain into a suitable oil drain container.
5. With the hose in position, use a 10 mm wrench or
socket and open the valve approximately 4 turns in the
counterclockwise direction. Allow 10 minutes for
engine oil to adequately drain.
6. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
7. Once the valve is closed, carefully remove the oil drain
hose and clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the exhaust system before operating the machine.
8. Clean the oil drain hose and store it appropriately.

Engine Air Filter

Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.

General Engine Maintenance

Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine Owner's
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
manufacturer. Special attention should be paid to applicable
data which will not be duplicated here.

Belts

Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:

• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
Slight raveling of belt covering does not indicate failure,
trim ravelings with a sharp knife.
If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose
steering control while operating the machine, place
the steering control levers in the park brake position
immediately. Inspect the machine and involve your
Hustler Dealer to resolve the problem before con-
®
tinuing to operate.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the
case, otherwise the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or dam-
age the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.
