AIR PANEL

1. The upper air pressure gauge indicates the air system operating pressure of 120 PSI (689 Kpa).

CAUTION: IF THE SYSTEM PRESSURE IS BELOW 100 PSI, OR ABOVE 120PSI, SHUT THE MACHINE DOWN AND CORRECT THE PROBLEM. Failure to heed this caution could result in machine damage.

2. Crowd Clutch Regulator - The crowd machinery is fitted with a clutch which will slip and protect the machinery from impact loads that may occur when digging.

3. Adjust the air regulator to obtain an air pressure of 80 PSI in the lower gauge. Further adjustment may be required due to digging conditions and friction material. Once set, no additional adjustment is required.

NOTE: The air supply line at the crowd clutch is equipped with a check valve that permits air flow into the clutch but not out. This check valve is there to prevent inadvertent loss of clutch action by accidentally exhausting air and possibly letting the dipper handle move in the boom yoke blocks without motor or brake control. This check valve is located inside the guard over the clutch. To exhaust air from the crowd clutch, the air supply line must be closed, the clutch guard removed and the air line to the clutch loosened to reduce the air pressure.

DANGER! RELEASE THE AIR LINE PRESSURE BEFORE REDUCING AIR PRESSURE TO THE CLUTCH. DO NOT ATTEMPT TO REMOVE ANY FITTINGS UNTIL THE AIR PRESSURE HAS COMPLETELY BLED OFF. FAILURE TO USE CAUTION COULD RESULT IN PERSONAL INJURY.
