Maintenance Instructions
The mechanical items of the lift axle system require periodic
maintenance to maintain reliable operation. Drain cocks, in the
bottom of each air tank, are installed to provide a convenient
means of periodically draining condensation from the tank.
Refer to the Lift Axle System maintenance chart SECTION 7

General Information
WARNING
To prevent personal injury or death, prevent
breathing brake lining fiber dust. Always use a
respirator while performing brake maintenance.
Follow precautions listed below.
WARNING
Always check and maintain brakes in proper
condition and adjustment. Out of adjustment
brakes could cause reduced braking ability and
result in property damage, personal injury, or
death.
All new International® vehicles use nonasbestos brake linings.
However, exposure to excessive amounts of brake material dust
may be a potentially serious health hazard.
Follow these precautions:
• Always wear a respirator approved by National Institute of
Occupational Studies of Health (NIOSH) or Mine Safety and
Appliance (MSA) during all brake service procedures. Wear
the respirator from removal of the wheels through assembly.
• Never use compressed air or dry brushing to clean brake
parts or assemblies.
• Clean brake parts and assemblies in the open air. During
disassembly, carefully place all parts on the floor to avoid
getting dust into the air. Use an industrial vacuum cleaner
with a HEPA filter system to clean dust from the brake
drums, backing plates, and other brake parts. After using
the vacuum, remove any remaining dust with a rag soaked
in water and wrung until nearly dry.
• Never use compressed air or dry sweeping to clean the work
area. Use an industrial vacuum cleaner with a HEPA filter
system and rags soaked in water and wrung until nearly dry.

the air. Use an approved respirator when emptying vacuum
cleaners and handling used rags.
• Worker cleanup. Wash your hands before eating, drinking,
or smoking. Vacuum your work clothes after use and then
launder them separately, without shaking them, to prevent
fiber dust from getting into the air.
