! WARNING
When working on air system components the following precautions
should be observed.
1. Stop engine when working under a vehicle. Always block the vehicle
wheels to prevent a fore or aft roll. Bleeding off system pressure may
cause the vehicle to roll. Keep hands away from brake chamber push
rods and brake adjusters; they may apply as system pressure drops.
2. Never connect or disconnect a hose or line containing air pressure.
It may whip as air escapes. Never remove a component or a pipe
plug unless you are certain all system air pressure has been
exhausted.
3. Never exceed recommended working air pressure and always wear
safety glasses when working with air pressure. Never look directly into
component ports or direct a pressurized air flow at anyone.
4. Never attempt to disassemble a component until you have read and
understood all recommended procedures. Some components contain
powerful springs and injury can result if not properly disassembled.
Use only proper tools and observe all precautions pertaining to the
use of those tools.
DISASSEMBLY
1. Exhaust air from the reservoirs. Do not proceed with disassembly
until the Dryer has completed the purge cycle and the compressor is
fully unloaded.
2. Loosen the Desiccant Canister with a strap wrench (OTC #7206,
Snap-On #A91C, or Equivalent) at the base of the canister and
spin-off by hand. Discard the Desiccant Canister.
3. Remove the Coalescing Filter and discard. The Filter could possibly
be contaminated with oil; therefore, it should be disposed of in
accordance with environmental standards.
4. Remove and discard the large O-Ring on the threaded canister
mounting nipple.
