User manual FLECO ATTACHMENTS HYDRAULIC COUPLER

[. . . ] NEVER USE FRONT JAW/REAR HOOK FOR LIFTING PURPOSE (LIFTING EYE ONLY). NEVER EXCEED THE SAFE WORKING LOAD ON LIFTING EYE. TRY TO NEVER TRY TO RELEASE THE COUPLER WHILE THE SAFETY PIN IS IN POSITION. [. . . ] Locate a pipe between the hydraulic oil tank and solenoid valve (Port T) for the return of hydraulic oil. Ports A & B on the solenoid valve must be attached to the hydraulic pipes that have been cable tied to the boom. (pipe A to close coupler, pipe B to open coupler) Locate maximum pump pressure via test port or tap into main pressure pipe between pump and valve bank on the crown cylinder circuit. A restrictor is supplied that must be fitted between the pump and port P on solenoid valve. (DO NOT USE SERVO PRESSURE TO OPERATE) INSTALLA ALLATION STEP 4. ELECTRICAL INSTALLATION Find a safe position in the cab to install switch and buzzer. (This must be located where it can not be accidentally activated. ) Always fuse live supply with 10-amp fuse. TESTING COUPLER Remove safety pin from coupler. Accelerate the excavator to no more than 50% rpm. Crowd coupler fully (extend crowd cylinder). Activate switch & put hydraulic system under pressure by continuing to extend crowd cylinder. Only when the switch is in the on position should the buzzer sound and power allowed to energize the solenoid valve which will put the coupler in the open position. When the switch is in the off position the solenoid should have no electric current running to it and the coupler will return to the closed position. Open and close the coupler several times to assist air bleed from the system. Check all hydraulic fittings on the coupler system and rectify any hydraulic oil leaks.

BUCKET OR ATTACHMENT PICKUP Remove safety pin from coupler. Fully crowd coupler and pressurize hydraulic system (this will open the hydraulic coupler). [. . . ] Activate switch to on position (buzzer sounding) and pressurize hydraulic system. 2. ) Slowly, crowd out the coupler with the bucket close to the ground. The hitch is then ready to pick up a new attachment or bucket. RECOMMENDED MAINTENANCE 1. ) Check the coupler, coupler cylinder, & hydraulic pipes for damage & replace or repair as necessary. [. . . ]
