Tires

Front tire: 16 x 7.5 x 8 - maximum recommended inflation is 24 PSI.
Rear tire: 15 x 4.0 x 8 - maximum recommended inflation is 40 PSI. Minimum inflation is 20
PSI.
Grease Locations
1. Grease both rear wheels, the two drive wheel bearings, and the steering pivot. (1 pump
each) Refer to page D-2. Do not over grease.
Parking Brake Adjustment

connecting rod.
3. Remove the lock nut that connects the lower

Turn the yoke end and connecting rod until the
desired new length is acquired. (Note: Maintain
