Drive System
Maintenance

Checking the Tire Pressure

Service Interval: Before each use or daily
Maintain the air pressure in the tires as specified.
Check the tires when they are cold to get the most
accurate reading.
Pressure: 103 to 138 kPa (15 to 20 psi)
Note:
Use a lower tire pressure, 103 kPa (15 psi),
when operating in sandy soil conditions to provide
better traction in the loose soil.

Checking the
Engine-Coolant Level
Service Interval: Before each use or daily
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the level of coolant at the beginning of each
day, before starting the engine.
DANGER
If the engine is running, the pressurized, hot
coolant can escape and cause severe burns.
• Do not remove the radiator cap when the
engine is hot. Always allow the engine to
cool at least 15 minutes or until the radiator
cap is cool enough to touch without
burning your hand before removing the
radiator cap.
• Do not touch the radiator and surrounding
g003793
parts that are hot.
• Use a rag when opening the radiator cap
and open the cap slowly to allow steam to
escape.
DANGER
The rotating shaft and fan can cause personal
injury.
• Do not operate the machine without the
covers in place.
• Keep your fingers, hands, and clothing
clear of the rotating fan and drive shaft.
• Park the machine on a level surface, lower
the loader arms, engage the parking brake,
shut off the engine, and remove the key
from the key switch before performing
maintenance.
