WARNING
Air system components are subject to high pressure. Always relieve pressure before
loosening or removing air system components. Failure to comply may result in injury or
death to personnel.
CAUTION
Ensure that external air source is as clean and dry as air supplied by vehicle. If in doubt,
use the vehicle's air supply. Contamination may cause damage to CTIS.
NOTE
Varying or intermittent air flow identifies a tire as having collected sufficient water to
cause icing of the air passage, even at temperatures above freezing.
