WARNINGS WARNING! Federal law (49 cfr part 571) requires that the Final Stage Manufacturer of a vehicle certify that the vehicle complies with all applicable federal regulations. Any modifications performed on the vehicle prior to the final state are also considered intermediate stage manufacturing and must be certified as to compliance. The installer of this crane and body is considered on of the manufacturers of the vehicle.

AC30A INSTALLATION INSTRUCTIONS 1 Locate air pump in a well ventilated area on truck body. 2 Secure to truck body through bottom side rails using four (4) 3/8- 24 NF x 2¾ Grade 5 bolts. Four (4) new 7/16 diameter holes may be made in the side frame rail to allow for obstruction problems. 3 Remove plastic cap from “T” port in the hydraulic valve block and install return line to cooler or reservoir.
OPERATION — AC30A BASIC OPERATION CAUTION: When the hydraulic system shuts down a shock wave is delivered to the return line. Locate the hydraulic coolers and filters a minimum of 10’ away. Air is drawn through the intake filter, intake manifold and suction discs into the cylinders. The air is compressed, then discharged through the delivery discs to the temperature reducer, where the heat of the compressed air is partly removed.
AC30A INITIAL START-UP PROCEDURE 1 Read the AC30A Owner’s Manual. Check all wiring for loose connections. 2 3 Check oil level in sight gauge. It should be filled to the middle of the sight glass. If not, fill to the proper level. Fill with PAO synthetic lubricant equivalent to Chevron-Gulf GSL 838A or Summit SH-46. If petroleum based crankcase oil is required by operator, use an SAE 10W oil, API classification CD of SF, Mil Spec MIL-L-2104C or MIL-L-46152.

½ X X 2 X YEARS NOTES EVERY 6000 RUN HOURS HIGH TEMPERATURES AND EXTENDED SERVICE MAY SHORTEN THE TIME BETWEEN HYDRAULIC OIL CHANGES. CHANGE HYDRAULIC SYSTEM FILTER FOR PAO (SYNTHETIC) OIL EVERY 3000 RUN HOURS FOR MINERAL BASED OIL EVERY 1000 RUN HOURS REPLACE AIR FILTER AFTER EVERY 600 RUN HOURS REMOVE AND CLEAN WITH COMPRESSED AIR ON-OFF PRESSURES SHOULD BE VERIFIED FOR CONSISTENCY. FURNAS SWITCH ADJUSTMENT. SUDDEN CHANGE IN PERFORMANCE INDICATES A PROBLEM MAY BE DEVELOPING.
AC30A TROUBLESHOOTING CAUSE/SOLUTION PROBLEM COMPRESSOR DOES NOT START. CAUSE: No electrical power. Receiver pressure between starting and stopping pressures. SOLUTION: Check or have electrical system checked. Wait until pressure drops. COMPRESSOR DOES NOT PUMP. CAUSE: Furnas Switch open. Solenoid valve not energized. SOLUTION: Have electrician check wiring. INSUFFICIENT AIR RECEIVER PRESSURE. CAUSE: Air leak(s). Air intake filter clogged. Air consumption exceeds unit capability.
AC30A TROUBLESHOOTING PROBLEM CAUSE/SOLUTION PRESSURE IN RECEIVER RISES ABOVE MAXIMUMAND CAUSES SAFETY VALVE TO BLOW. CAUSE: Furnas switch incorrectly set or out or order. Solenoid valve defective. SOLUTION: Set switch to stop compressor at rated maximum pressure. Replace switch it does not respond. Remove and test valve on outside mains supply line. Replace, if out of order. RECEIVER DOES NOT HOLD PRESSURE. CAUSE: Discharge check valve leaks. SOLUTION: Replace.
AC30A TROUBLESHOOTING PROBLEM CAUSE/SOLUTION LOADING PERIODS TOO LONG CAUSE: Excessive air consumption. Compressor not in optimum condition. Sticking or damaged valves. SOLUTION: Decrease consumption. Have compressor inspected. 4-2.2.
AC30A TROUBLESHOOTING SET UP SYSTEM TEST 1 Install flow meter in Port “A” high pressure line to the hydraulic motor. 1 Engage PTO and raise the truck engine RPM to the proper setting without starting the air compressor. Record the main hydraulic flow through Port “A” and the system pressure. Record hydraulic motor/compressor RPM with a phototach. 2 Install a 3000 psig pressure gauge in Port “A” before the flow meter. This will read system pressure.
AC30A TROUBLESHOOTING 7 If the air compressor fails to start and the hydraulic pressure is low: A. Check the red power wire for + 12 volts DC. 8 If the compressor fails to start and the hydraulic pressure is high: A. Check power to hydraulic solenoid coil at Furnas switch B. Check to see if the air tank 9 If the motor flow is 12 GPM and the compressor is turning less than 1700 pressure is higher than the system RPM the motor has degraded enough reset pressure (usually 110 psig).
