CAUTION: Avoid the possibility of personal injury. Never operate tractor with loose wheel bolts. Failure to follow procedure may result in personal injury. Wheel bolts are critical to operation and require repeated torquing to assure secure tightness.

IMPORTANT: Some bolts may loosen as sleeve is tightened. Repeat torquing sequence until ALL bolts maintain proper torque. Failure to follow procedure could result in damage to equipment.

Tighten wheel to hub bolts (1-10) to initial torque specifications - in numerical sequence shown - until torque is maintained.

Tighten bolts to final torque specifications - in numerical sequence - until torque is maintained.
