6. Turn the tank valve clockwise (CW) and close the
valve.
7. Disconnect the air chuck from the valve stem.
8. Turn the regulator valve counterclockwise (CCW) to
the off position.
9. Use a tire pressure gauge to check the tire pressure. If
necessary, put more air into the tire. Do this as many
times as necessary to reach the correct tire pressure.
CAUTION
!
Use a long-handled gauge so that your hand
does not go inside the cage, or in front of any
component of a multi-piece wheel.
Checking and Adjusting Tire Pressure
WARNING
!
Before you add air pressure to the tire, make
sure the lock ring is correctly positioned in
the rim and wheel wedge. The lock ring can
separate from the rim with enough force to
cause injury or death.
1. Attach a clip-on air chuck to valve stem. Stand by the
side of the wheel and put the correct air pressure in
the tire.
2. If your air supply does not have enough pressure to
fill the tire, you can use a nitrogen cylinder to get the
correct pressure.
3. Put a clip-on type air chuck on the nitrogen cylinder
hose and attach it to the valve stem. Follow the pro-
cedures described previously for adjustment of the
nitrogen cylinder valves.
WARNING
!
Use nitrogne only. Do not use oxygen or any
other gas to fill tires.
