INTRODUCTION
The Auto-Pump Air Compressor system is a compact electric motor operated single cylinder
air compressor designed specifically for installation on vehicles with air brakes . During long
idle periods of the vehicle when even the slightest seepage can cause an air brake system
pressuretodropbelowthebrakelockuppressure,theAutoPumpautomaticallystartstomaintain
the pressure.
The Auto Pump motor is directly coupled to the compressor section eliminating all belts and
pulleys assuring long life and reliable operation . A heavy duty pressure switch is adjusted
to start the compressor when the system pressure drops below 75 psi and stops the compressor
when 95 psi is attained . The start up pressure is field adjustable - the pressure differential
between start up and stopping is fixed. Please read and follow the installation instructions
carefully . The Auto Pump requires no routine maintenance . A careful installation will assure
years of trouble free operation.

8. An optional Mounting Plate 091-9H is available to reduce any vibration and noise from Auto
Pump and to simplify pump mounting.
NOTE: Compressor must be mounted above air
tank to assure that moisture will flow away from
compressor.

COMPRESSOR OUTPUT IS 100 PSI MAXIMUM. DO
NOT EXCEED 100 PSI OR YOU WILL VOID WARRANTY.
1. Remove cover of the Pressure Switch on the Auto Pump.
2. Wire the pressure switch to the battery and a good chassis ground, use #14 AWG WIRE
MINIMUM .
3. Reinstall cover of Pressure Switch .
4. The compressor is calibrated to cut-in at 75 PSI and cut-out at 95 PSI . For higher cut-in and
cut-out, turn the range nut clockwise . To lower cut-in turn range nut counterclockwise . Do
not exceed 100 PSI .
5. 091-9 AUTO PUMP can be wired to a positive or negative system vehicle .
