Connecting The Tyre Inflator; Troubleshooting - GMC MOC6L Instruction Manual

Connecting the tyre inflator

1. To connect the tyre inflator,
select one of the supplied 1/4"
male Nitto style plugs/adaptors
(21). Apply the supplied Teflon
tape to the male thread on
the 1/4" male Nitto style plug/
adaptor (21). Screw the 1/4"
male Nitto style plug/adaptor
(21) into the 1/4" female thread
of the tyre inflator (18). Tighten this fitting with a wrench for
an air tight seal (Fig. N).
2. Connect the completed assembled tyre inflator to the air
line by pulling back the outer sleeve of the quick coupler
at the end of the air hose and insert the tyre inflator
assembly. Once inserted, release the outer sleeve of
the coupling and make sure the accessory and hose are
securely connected.
3. To operate the tyre inflator insert the tyre valve inlet
connection into the tyre inflator.
Problem
Motor will not run, running too
slow or becoming excessively hot
Main compressor sticking/tight
4. Firmly press the tyre inflator down; doing so opens
both the valve on the tyre and the valve on in the tyre
inflator allowing air to flow through. Use a tyre gauge to
N
check air pressure in the tyres. Check the ratings printed
on the side walls of the tyre that you are inflating for
reference as to the recommended maximum air pressure
requirement. DO NOT EXCEED the maximum pressure
ratings on the tyre you are inflating.
IMPORTANT.
• The tyre inflator should only be used for its intended
purpose to inflate tyres.
• Do not discharge air through the inflator without it being
fitted to a tyre.
• Never apply the outlet of the tyre inflator against a
person's body.
• Never look down the air outlet hole of the inflator.
• Never point the tyre inflator at anyone.
• Do not over inflate the tyres beyond the recommended air
pressure from the tyre manufacturer.
