Drive System
Maintenance
Checking the Tire Pressure
Service Interval: Every 50 hours
Maintain the air pressure in the tires at 35 psi (241 kPa)
(Figure 42). Uneven tire pressure can cause the tracks to
slip. If the tracks slip, evenly increase the tire pressure
in each tire by 10 psi (69 kPa) until the tracks no longer
slip when driving. Do not exceed 50 psi (345 kPa) in
each tire.

Note: Check the tires when they are cold to get the
most accurate pressure reading.
Cooling System
Maintenance
Discharge of hot pressurized coolant or
touching hot radiator and surrounding parts
can 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 radiator and surrounding parts
that are hot.
The rotating fan and drive belt can cause
personal injury.
• Do not operate the machine without the
covers in place.
• Keep fingers, hands and clothing clear of
rotating fan and drive belt.
• Shut off the engine and remove the ignition
key before performing maintenance.
Swallowing engine coolant can cause poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.
Checking the Cooling System
Service Interval: Before each use or daily—Check the
engine coolant level.
The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti freeze. Check
the level of the coolant in the expansion tank at the
beginning of each day before starting the engine. The
capacity of the cooling system is 6 quarts (7.5 l).
