  If the coupler cylinder on your paladin Construction Equipment isn't extending, it could be due to several reasons. The hoses or valve might be blocked by dirt, in which case you should remove and clean them, then blow air through the valve to check its operation. Another possibility is incorrect pressure; check the pressure in the coupler cylinder extend “EXT” line (High Pressure System - full system pressure, Low Pressure System - 3250 PSI), inspect the coupler cylinder check valve o-rings for damage, and ensure the hoses aren't pinched or the fittings/coupler cylinder tubes are not damaged. Lastly, the locking mechanism may be binding; remove any debris from the coupler and lubricate the coupler grease points.

  If the coupler cylinder on your paladin Construction Equipment doesn't retract, several factors could be at play. First, the bucket cylinder might not be relieving pressure. Second, dirt may be plugging the hoses or valve; in this case, remove and clean the hoses and valve, then blow air through the valve to verify its operation. Third, there may be incorrect pressure; check the pressure in the coupler cylinder retract “RET” line (High Pressure System - full system pressure, Low Pressure System - 3250 PSI). Finally, check electrical connections and primary ground, and ensure the correct voltage is supplied to the coils (12 volts to 12-volt coils and 24 volts to 24-volt coils). Also, remove debris from the coupler and lubricate the grease points. Ensure the coupler is rotated to the full cu...
