Checking the Tire Pressure

Service Interval: Every 50 hours
Maintain the air pressure in the front and rear tires. The
correct air pressure is 172 kPa (25 psi) in the rear tires and
103 kPa (15 psi) in the front tires. If a cab is installed on the
machine, the front and rear tires should be inflated to 172
kPa (25 psi). Uneven tire pressure can cause an uneven cut.
Check the tires when they are cold to get the most accurate
pressure reading.

Cooling System Safety

CAUTION
Discharge of hot, pressurized coolant or touching a
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 the radiator and surrounding parts
that are hot.
DANGER
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
DANGER
The rotating fan and drive belt can cause personal
injury.
• Do not operate the machine without the covers
in place.
• Keep your fingers, hands and clothing clear of
rotating fan and drive belt.
• Shut off the engine and remove the ignition key
before performing maintenance.
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 7.5 L (6 US qt).
1. Check the level of the coolant in the expansion tank
(Figure 34). The coolant level should be between the
marks on the side of the tank.
2. If coolant level is low, remove the expansion tank cap
and replenish the system. Do not overfill.
