CAUTION
Ensure that semitrailer tank is empty before
operating emergency valve and vapor vent control
levers.
NOTE
Emergency valve and vapor vent control levers
should offer resistance when pulled. This is normal.
e. Operate emergency valve and vapor vent control levers in
cabinet (see paragraph 2-2). Operation should be smooth and free
of binding. If operation is not smooth, trace cable and tubing
assembly and check for proper lubrication at union of tubing grease
fittings. Lubricate as required (see Chapter 3, Section I).
f. Check for breaks, kinks, or frays in emergency valve cable and
tubing assembly, or looseness of mounting hardware. Tighten
loose mounting hardware and/or replace damaged components as
required. Adjust length of cable at BOTH ends as required (see
paragraphs 4-74 and 4-76).
g. Inspect pressure gage and precheck valve in cabinet for
looseness or damage to mounting hardware or fittings. Turn handle
of precheck valve and check for smooth, free operation. If handle
turns with difficulty, precheck valve may have internal damage.
Check condition of all precheck tubing. Be alert for signs of leaks.
Tighten loose mounting hardware or fittings. Replace any damaged
component (see paragraph 4-72).
h. Check wheel bearing lubricant level at hubcaps. If level is below
fill mark, remove hubcap plug and add proper lubricant until even
