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

pressure 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

carefully . The Auto Pump requires no routine maintenance . A careful installation will assure

years of trouble free operation.
