Failure to maintain proper torque of the wheel nuts
could result in failure or loss of wheel and may
result in personal injury.
Torque the front and rear wheel nuts to 85-100 ft.-lb.
(115-136 N·m) after 1-4 hours of operation and again
after 8 hours of operation. Torque every 200 hours

Service Interval: Every 400 hours
Check the oil level after every 400 hours of operation. Use
high quality SAE 85W-140 wt. gear lube as a replacement.
1. With machine on level surface, position the wheel so
one check plug (Figure 61) is at the 12 o'clock position
and the other is at 3 o'clock position.
1. Check/drain plug (3 o'clock position)
2. Remove the plug at the 3 o'clock position (Figure 61).
Oil level should be within 6 mm (1/4 inch) of the
check plug hole.
