T ROUBLESHOOTING 4.1 General Procedures 4.1-1 Truck System Requirements Truck hydraulic pressure should be within the range shown in Specifications, Section 6.1. PRESSURE TO THE FORWARD BIN DUMPER MUST NOT EXCEED 2300 psi (160 bar). Truck hydraulic flow should be within the volume range shown in Specifications, Section 6.1. Hydraulic fluid supplied to the Bin Dumper must meet the requirements shown in Specifications, Section 6.1. WARNING: Before servicing any hydraulic component, relieve pressure in the Attachment system. Turn the truck off and move the truck auxiliary control handle several times in both directions. After completing any service procedure, always test the Attachment through several cycles. First test the Attachment empty to bleed any air trapped in the system to the truck tank. Then test the Attachment with a load to be sure it operates correctly before returning to the job. Stay clear of the load while testing. Do not raise the load more than 4 in. (10 cm) off the floor while testing. 4.1-2 Tools Required In addition to a normal selection of hand tools, the following are required: 20 GPM (80 L/min) inline flow meter. (Cascade Flow Meter Kit, part no. 671477). 3000 psi (200 bar) pressure gauge. (Cascade Pressure Gauge Kit, part no. 671212). Quick-disconnect adapters and fittings.

The first step is to talk to the equipment operator. Ask for a complete description of the malfunction. Guidelines below can then be used as a starting point to begin troubleshooting. Dump Circuit Bin retainers do not close or hold bin properly. Attachment dumps or retracts slowly or not at all. To correct these problems, see Section 4.3. Sideshift Circuit Attachment will not sideshift. Attachment sideshifts slowly.

T ROUBLESHOOTING 4.3 Dump Function There are six potential problems that could affect the dumping function: Incorrect bin size or load handling. Refer to Operator s Guide for suggested procedures. Damaged front bin retainer or pushrod. Incorrect hydraulic pressure or flow from lift truck. External leaks. Defective solenoid coil or valve (if equipped). Defective counterbalance valve or cylinder seals. 4.3-1 Supply Circuit Test 1 Check the pressure supplied by the truck at the carriage hose terminal. Pressure must be within the range shown in Specifications, Section 6.1. PRESSURE TO THE BIN DUMPER MUST NOT EXCEED 2300 PSI (160 BAR). 2 Check the flow volume at the carriage hose terminal. Flow must be within the range shown in Specifications, Section 6.1. 3 Tilt the dumper fully forward, holding the lever in the FORWARD position for a few seconds. Release the lever and check for external leaks at fittings, hoses, valve and cylinders. 4.3-2 Dump Circuit Test 1 Press the solenoid button (if equipped) and listen for a click at the solenoid valve. If no sound is heard, first check the fuse, wiring and coil. Assure that the valve is not jammed (see Sections 4.5 and 5.5). IMPORTANT: Solenoid-operated valves must be plumbed so that the solenoid is energized during the dumping function. 2 Tilt the dumper FORWARD. Turn the truck off and relieve Attachment system pressure. 3 Using a No. 4 tee fitting, connect a 3000 psi (200 bar) pressure gauge to either cylinder rod-end port, routing the gauge and hose out the bottom of the lower frame. 4 Start the truck and retract the dumper, holding the lever in the BACK position for a few seconds. 5 Release the lever and watch the pressure gauge: If the pressure drop is less than 150 psi (10 bar) initially, and additional drop does not exceed 25 psi (2 bar) per minute, the problem is not hydraulic (see Section 4.3 above). If the pressure drop is more than 150 psi (10 bar), the counterbalance valve or the cylinders are at fault and must be serviced (see Sections 5.3-2 and 5.4). NOTE: The Attachment must be removed from the truck in order to service the valve and the cylinders. Flow Meter 2 WARNING: Before removing hydraulic lines or components, relieve pressure in the Attachment hydraulic system.

T ROUBLESHOOTING 4.4 Sideshift Function There are six potential problems that could affect the sideshifting function: Inadequate upper bearing lubrication or worn bearings (see Section 3). Incorrect hydraulic pressure or flow from lift truck (see Section 6). External leaks. Lower mounting hooks installed incorrectly (see Section 2, Step 6). Worn or defective cylinder seals (see Section 4.4-2). Cylinder fittings or flow restrictors plugged, incorrect type, or not installed correctly (see Section 5.5). 4.4-1 Supply Circuit Test 1 Check the pressure supplied by the truck at the carriage hose terminal. Pressure must be within the range shown in Specifications, Section 6.1. PRES- SURE TO THE SIDESHIFTER MUST NOT EXCEED 2300 PSI (160 BAR). 2 Check the flow volume at the carriage hose terminal. Flow must be within the range shown in Specifications, Section 6.1. 3 Sideshift left fully, holding the lever in the SIDESHIFT LEFT position for a few seconds. Release the lever and check for external leaks at fittings, hoses and cylinder. 4.4-2 Sideshift Circuit Test 1 Press the solenoid button (if equipped) and listen for a click at the solenoid valve. If no sound is heard, check the fuse, wiring and coil (see Section 4.5). Assure that the valve is not jammed (see Section 5.6). IMPORTANT: Solenoid-operated valves must be plumbed so that the solenoid is not energized during the sideshifting function. 2 Sideshift fully to the left. Turn the truck off and relieve Attachment system pressure. Disconnect the SIDE- SHIFT RIGHT supply hose from the hose terminal and route the hose to a drain bucket. Cap the hose terminal supply. 3 Start the truck and actuate the SIDESHIFT LEFT lever for 5 seconds. If there is substantial hydraulic flow out of the drain hose, the sideshift cylinder is faulty and requires service. If there is no hydraulic flow out of the hose, check for plugged or incorrectly-installed flow restrictor 3 washers and fittings. If there is still no hydraulic flow, the problem is not hydraulic (see Section 4.4). Sideshift Right Hose 2 Hose end in drain bucket WARNING: Before removing hydraulic lines or components, relieve pressure in the Attachment hydraulic system.

T ROUBLESHOOTING 4.5 Electrical Circuit (solenoid-equipped units) Use the electrical schematic and diagram shown and follow the steps below: 1 Check the control knob circuit fuse. Replace if necessary. 2 Check for loose electrical connections at the truck ignition switch, control knob button, solenoid coil terminals and diode. 3 Remove the diode from the solenoid coil terminals. Test with an ohmmeter for high resistance in one direction and no resistance in the other direction. If there is no resistance in both directions, replace the diode. NOTE: When replacing the diode, the banded (+) end must be connected to the coil and wiring as shown. 4 Disconnect the electrical leads from the solenoid coil terminals. Use a voltmeter to determine if voltage is present at the electrical leads when the button is depressed. If there is no current to the solenoid, troubleshoot the electrical circuit for shorts. If there is current to the solenoid, test for coil continuity. 5 Test for coil continuity by placing an ohmmeter test lead on each solenoid coil terminal (ohmmeter on Rx1 scale). If there is an ohmmeter reading, the coil is good. If the coil is good, but the solenoid does not 'click' when the control knob button is depressed, the solenoid cartridge may be jammed. Refer to Section 5.6-2. If there is no ohmmeter reading, the coil is defective and should be replaced. Refer to Section 5.6-1.

Lubricate new seals and O-rings with petroleum jelly. 3 Install new seals, O-rings and back-up rings on the piston and retainer. Hook one side of the seal in the groove and carefully work it over the piston or retainer. 4 Note the direction of the U-cup seals (see illustration below). Pressure seals are installed with the lip toward the high pressure side of the cylinder. The cylinder will not work properly if the seals are turned around. 5 Apply petroleum jelly to the retainer I.D. and install the retainer, then the piston on the cylinder rod. Use a new piston retaining nut and tighten to 125 ft.-lbs. (170 Nm). 6 Apply petroleum jelly to the piston and install the piston/ rod assembly into the cylinder shell. Use a rubber or plastic mallet as needed. 7 Screw the retainer into the shell and tighten to 250 ft.-lbs. (340 Nm).
