decrease.
The air pressure gauge will dis-

is turned on.
Inject to recommended pressure.
• Turn the compressor switch off and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat the
inflation procedure until the spec-
ified tire inflation pressure is
reached.
