pressure.
Wrong gauge wire or length of

CORRECTION
If there is an excessive amount of
pressure drop when the accessory
is used, adjust the regulator
following the instructions on page
7.
NOTE: Adjust the regulated
pressure under flow conditions
(while accessory is being used).
Let motor cool off and overload
switch will automatically reset.
Motor will start automatically when
tank pressure drops below "cut-in"
pressure of pressure switch.
Check for proper gauge wire and
cord length.
Remove and clean, or replace.
Check wiring connection inside
pressure switch and terminal box
area.
Contact an Authorized Warranty
Service Center for inspection or
replacement, if necessary.
Have checked by an Authorized
Warranty Service Center. Do not
operate the compressor in the paint
spray area. See flammable vapor
warning.
1. Check fuse box for blown fuse
and replace, if necessary. Reset
circuit breaker. Do not use a
fuse or circuit breaker with
higher rating than that specified
for your particular branch circuit.
2. Check for proper fuse; only time
delay fuses are acceptable.
3. Check for low voltage
conditions and/or proper
extension cord.
4. Disconnect the other electrical
appliances from circuit or
operate the compressor on its
own branch circuit.
Bleed the line by pushing the lever
on the pressure switch to the "off"
position; if the valve does not open,
replace it.
