WARNING
Improper tightening of boom lift trailer wheel nuts can cause wheel lugs to shear,
causing serious injury or damage to equipment. Check and maintain the proper
wheel nut torque according to the maintenance instructions in this manual.
Periodically check the wheel nut torque according to the instructions in Section 4 of this
manual. More frequent torque checks are required when a wheel is recently installed.
Prior to towing, while the trailer wheels are elevated for boom lift operation, check for
loose wheels and for wheel lug wear indications. If a loose wheel mounting is indicated,
remove and inspect the wheel lugs for damage. Do not tow the boom lift with worn or
damaged wheel lugs.
