Why paladin Construction Equipment coupler cylinder does not extend?
- JJason GriffithAug 15, 2025
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.
