Overload Relay Protection
(if so equipped)
An overload relay will stop the unit if the motor
becomes overheated. (Causes for overheating of the
motor can be found in TROUBLESHOOTING.) Once
the overload relay has been tripped, the motor must
cool and the red overload button on the motor must
be reset be fore the unit will start.

Overload relays are designed to protect the motor
from damage due to motor overload. If the overload
relay trips persistently, DO NOT CONTINUE TO PUSH
THE RESET BUTTON! Contact your local Quincy
distributor for assistance.

of additional air hose is recommended rather than
an exten sion cord. If an extension cord is to be used,
it must be a 3 wire cord with a 3 prong plug. Refer
to the following chart to determine the wire gauge
required in relation to the cord length:
