GENERAL SAFETY INSTRUCTIONS
Never remove tire locknuts before deflating tire.
Never use tubes in wheel assembly.
Always use tire cage when inflating tire.
Mount only tires recommended for vehicle
Never use tubes in wheel assemblies. The wheel is designed
for tubeless application. Use of a tube defeats built-in safety
features and could allow the wheel to come apart under
pressure, resulting in serious injury to personnel.
Rim surfaces and safety pressure relief grooves in the inner
rim must be kept clean and free of dirt. Rust and dirt could clog
safety relief grooves, causing the assembly to separate under
pressure if improperly disassembled, causing injury to personnel.
Never use wheel assemblies with studs or flanged locknuts
which are cracked, broken, rusted, pitted, bent, or which have
loose studs or damaged, mutilated, or deformed threads.
Damaged or rusted fasteners can cause improper assembly,
which could cause the assembly to separate under pressure or
could cause individual fasteners to fail. Any of these conditions
could result in serious injury to personnel.
In all disassembly operations, ensure tire is totally deflated
before removing wheel nuts. Remove valve core and exhaust
all air from tire. Check the valve stem for obstacles by running
a piece of wire through it. Failure to follow proper safety
precautions could cause serious injury or death.
1.
Place tire (1) in tire inflation cage.
NOTE
Run a piece of wire through valve stem to ensure it is not plugged.
