PRESSURE REGULATOR ADJUSTMENT

After setting idle speed and compressor is in run position, the pressure regulator adjustment can be checked and adjusted if required.

The air cylinder receives an air signal from the pressure regulator. This air cylinder controls engine speed with air demand. To adjust pressure regulator, with compressor in the run position, open service valve slightly to allow air to bleed out. By watching air pressure gauge note when air cylinder starts to retract, this should be approximately 105 psig. If cylinder does not start to retract until at a lower pressure, the regulator is set to low. The regulator has a locknut and adjustment screw. Loosen the locknut and turn adjustment screw clockwise to increase the pressure. Turning screw counter clockwise decreases pressure. After adjustment is complete, tighten locknut.

Note: If you unit is rated a higher pressure add 5 PSI to the working pressure; ex: 150 PSI working = 155 retract pressure.

RATED SPEED ADJUSTMENT

With the compressor in a run position open service valve slowly until pressure gauge is reading 100 PSI (working pressure). Check that air cylinder is fully retracted, moving throttle arm to full speed and check the engine speed. Adjust the speed to within the specifications in the front of this manual. To adjust there are two adjusting screws on throttle arm, the adjusting screw towards rear of engine is the high-speed adjustment. Loosen locknut on adjustment screw by turning screw counter clockwise, speed increases, after setting speed to specifications, tighten locknut, close service valve and allow compressor to unload and return to idle.

4.13 INSTRUMENTS

The standard control panel has gauges for air pressure, oil pressure, coolant temperature, ammeter and hourmeter. Also included is an ignition switch, start/run valve and safety bypass switch. The safety bypass switch cuts out the low oil pressure switch to permit starting. The low oil pressure switch is normally opens and closes upon activation. Safety shutdowns are also provided for high compressor oil temperature and high engine coolant temperature. These switches are normally closed and upon activation. If the compressor will not start or shuts down while in operation without an obvious malfunction, each switch can be checked individually by connecting a jumper wire across the terminal posts one switch at a time. The defective switch must be replaced.

NOTE: the existing wiring harness must be connected to the safety switches while making the above check.

4.14 BATTERY

Batteries supplied with Boss compressors are selected to have ample cold cranking amperes for quick starts in inclement weather. Keep them fully charged and if replacement is necessary the replacement must be of equal capacity.

WARNING

BATTERY GAS CAN EXPLODE CAUSING ACID BURN TO SKIN AND BLINDNESS. DO NOT OVERCHARGE OR JUMP THE BATTERY INCORRECTLY.
