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 pres-
sure to drop below the brake lockup pressure, the Auto Pump automatically starts to maintain
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 care-
fully. The Auto Pump requires no routine maintenance. A careful installation will assure years
of trouble free operation.
