Motor
I:he motor has a thermal ovedoad prOtector.If the motor
_verheats for any reason, the overload protector will ;hut off the motor. The motor must be allowed to cool
_efore restarting. Turn the
)FF position. Depress the reset button Iocaled on the _nd of the motor. To restart, turn the
_itch to the ON position. Refer to Figure 1.
Note
If the overload protector shuts the motor off fre- quently, check for a possible voltage problem.
Low voltage can also be suspected when"
1.The motor does not get up to full power or speed;
2.Fuses blOw out when starting the motor.
3.Lights dim and remain dim when motor is started.
'i
....Note
=
Avoid using long extension cords. They can
cause a power loss to the motor, Add extra air hose instead of extension cords.
If an extension cord must be used:
-use only a
-make sure the cord is in good condition.
-the cord should bend longer than 50 feet.
-the minimum wire size is 12 gauge (AWG). (Wire size increases as gauge number decreases. 10 AWG and 8 AWG mayatso be used, 0o not use 14 AWG or 16
AWG,)
Pressure Release Valve
The pressure release valve located on the side of the pressure switch is designed to unload air from the com- pressor head automaUcally al unit shut off. This protects the motor from starting against air pressure remaining in the compressor head and tubing. When the motor stops running, air will be heard escaping from the valve for a few seconds. When the motor is running, no air should
be leaking from the pressure release valve.
MAINTENANCE
Replacing Air intake Filter
A dirty air intake filter will not allow the compressor to operate at full capacity. When the intake filter becomes dirty, oily, or covered with paint overspray, replace it. Do not Operate the compressor with the air intake filter removed. To replace the filter, use needle nosed pliers and pull or pry the old filter out. Replace with new. Refer to Figure 1.
Checking Safety Valve
WARNING l_
RUPTURE OR EXPLOSION MAY OCCUR 1= THE SAFETY' VALVE DO=S NOT WORK
PROPERLy. OCCASIONALLY PULL THE RING ON THE SAF__TY VALVE TO MAKE SURE THAT THE VALVE OPERATES
FRE£LY. IF THE VALVE IS STUCK OR DO_S NOT OPERATE SMOOTHLY, IT MUST BE
REPLACED.
