Checking the
Front-Differential-Oil Level
4-Wheel-Drive Models Only
Service Interval: Every 100 hours/Monthly (whichever
comes first)
Differential-oil type: Mobil 424 hydraulic oil
1. Position the machine on a level surface.
2. Clean the area around the fill/check plug on side of
the differential

1. Fill/check plug
3. Remove the fill/check plug and check the level of the
oil.
Note: The oil should be up to hole.
4. If the oil is low, add specified oil.
5. Install the fill/check plug.
Checking the Torque of the
Wheel Nuts
Service Interval: After the first 2 hours
After the first 10 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel nuts
could result in failure or loss of a wheel and may
result in personal injury.
Torque the front and rear wheel nuts to 109 to 122
N·m (80 to 90 ft-lb) after 1 to 4 hours of operation
and again after 10 hours of operation. Torque every
200 hours thereafter.

Checking the Tire Pressure
Service Interval: Before each use or daily
The air pressure in the front tires should be 220 kPa (32 psi)
and the rear tires should be 124 kPa (18 psi).
Important: Check the tire pressure frequently to ensure
proper inflation. If the tires are not inflated to the correct
pressure, the tires will wear prematurely and may cause
4-wheel drive to bind.
Figure 22
is an example of tire wear caused by under inflation.

Checking the Brake-Fluid
Level
Service Interval: Before each use or daily—Check the
brake-fluid level. (Check the level before
the engine is first started and every 8
hours or daily, thereafter.)
Every 1,000 hours/Every 2 years (whichever comes
first)—Change the brake fluid.
Brake fluid type: DOT 3 brake fluid
The brake-fluid reservoir is located under the dash.
