6.7 TIRES AND WHEELS

Inspect tires periodically for wear or damage. Tires with worn

edges or distorted profiles require replacement. Tires with sig-

nificant damage in the tread area or side wall, require immediate

evaluation before replacing the machine into service.

Replacement wheels must have the same diameter and profile

as the original. Replacement tires must be the same size and

rating as the tire being replaced.

It is extremely important to apply and maintain proper wheel

mounting torque.

WHEEL LUG NUTS MUST BE INSTALLED AND MAINTAINED AT THE

PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN LUG NUTS,

AND POSSIBLE SEPARATION OF WHEEL FROM THE AXLE. BE SURE

TO USE ONLY THE LUG NUTS MATCHED TO THE CONE ANGLE OF THE

WHEEL.

SECTION 6 - GENERAL SPECIFICATIONS AND OPERATOR MAINTENANCE

– JLG Lift –

Tighten the lug nuts to the proper torque to prevent wheels from

coming loose. Use a torque wrench to tighten the fasteners. If

you do not have a torque wrench, tighten the fasteners with a

lug wrench, then immediately have a service garage or dealer

tighten the lug nuts to the proper torque. Over-tightening will

result in breaking the lug nuts or permanently deforming the

mounting holes in the wheels. The proper procedure for attach-

ing wheels is as follows:

1. Start all lug nuts by hand to prevent cross threading. DO

NOT use a lubricant on threads or nuts.

2. Tighten lug nuts in the following sequence.
