Connecting LIKUFIX

In addition, note the following: Before installation, remove the protective covers on the quick change adapter 1 and the working tool 2. Always keep hydraulic couplings 3 and 4 clean. Perform a visual check for cleanliness before installation. If necessary, clean all coupling parts and the sealing surfaces with a clean, oil-soaked cloth. When changing a work tool, connect or disconnect the hydraulic coupling slowly. When attaching the quick change adapter, tilt it until the coupling plates are connected due to the curb weight of the working tool. Extend the locking pins. If the plates do not connect as a result of curb weight, foreign objects (such as stones) may be the cause. In this case, clean all coupling parts to prevent damage when connecting. The oil flow and pressure must be matched to the corresponding work tool. When the work is completed, and particularly before transport, reattach the protective covers 1 and 2.
