Tank fills slowly
Cannot get air out of
tank
Water in tank
Possible Cause(s)
Air leaks
1.
Universal adapter dirty
and not sealing
2a. Hose damaged
2b. Hose connection to
manifold loose
3a. Gauge damaged

loose
4a. Manifold damaged or
defective relief valve
4b. Manifold connection
loose
5.
Pin hole from internal
rusting
1. Gauge not reading correctly
2. Compressed air source
below 85 psi
1. Fill valve obstructed or
damaged
2. Low volume air output
source
1. Low tank pressure
2. Hose shutoff valve closed
3. Universal adapter damaged
Contaminated compressed air
source
Corrective Action
Use mild soapy water to locate leak
1.
Clean dirt from universal adapter. Close hose shutoff valve
and replace hose assembly
2a. Replace hose assembly
2b. Remove hose, apply thread sealant and tighten fitting into
place
3a. Replace gauge
3b. Remove gauge, apply thread sealant and tighten
4a. Replace manifold
4b. Remove manifold, apply thread sealant and tighten
5.
Replace tank
1. Check air pressure at fill stem with tire pressure gauge.
Replace gauge if gauge reads differently
2. Locate compressed air source of 85 to 125 psi
1. Inspect opening for foreign material, clean or replace
2. Locate compressed air source of 85 to 125 psi
1. Tank pressure must exceed tire pressure. Increase tank
pressure
2. Turn red knob on manifold counterclockwise to fully open,
1-1/2 turns
3. Replace hose assembly
Drain water from tank. Refer to maintenance section for
