    3. OPERATION 3.1 HOW THE COMPRESSOR WORKS 3.1.1 COMPONENTS The basic components of the air compressor are the gasoline engine, pump, tank and unloader. The gasoline engine (item A) powers the pump. The engine drives a pulley and belt, which transfers power from the engine to the pump pistons via a flywheel and a crankshaft.
  • Page 4 3.1.2 CONTROLS 1. Unloader/Check Valve The unloader (see Figure 2 below) maintains pressure between the “cut-in” and “cut-out” pressure levels. At low-pressure levels, all the compressor discharge air passes through the unloader into the tank. When the tank air pressure reaches the desired cut-out pressure, the vent port in the unloader opens allowing all compressor discharge air to be vented to atmosphere.

    3.1.3 INLET AIR SYSTEM A clean, cool and dry air supply is essential to the satisfactory operation of your compressor. The standard air filter that the compressor is equipped with when leaving the factory is of sufficient size and is designed to meet normal conditions, when properly serviced in accordance with the maintenance section of this manual.

Seized pump Contact authorized service center. Low engine idle speed or improper Refer to Engine Operator’s Manual. carburetor setting Low discharge pressure Air leaks Tighten or replace leaking fittings or connections.

Discharged battery Recharge Compressor too cold Move compressor to a warmer location. Using wrong grade oil Use ISO 1001 30W compressor oil in temperatures above 30°F (-1°C) and 10W oil below 30°F (-1°C).
