T Re 3 Troubleshooting and grease information Grease your chuck at regular intervals Grease will dissipate based on cycles It is recommended to grease the chuck daily Indications of low grease or lack of greasing are run out and or loss of grip force possible part slippage e Recommended grease for the UBL chuck is Chevron Coupling grease factory supplied e Without a part in place apply grease to each arm fitting 3 5 shots along the outside diameter until grease is released from the pipe plug The lower fitting should get more grease as this is the one that will pop the pressure valve e Actuate the chuck at full stroke approx 5 to 10 times This will further distribute grease throughout the chuck e Re apply grease to the chuck until the grease is released e Another source of part slippage is cylinder pressure Ensure that cylinder pressure is at the recommended level e If part roundness is deteriorating the jaw homing may not be functioning proper ly To check this use a wrench to twist the arm without a part loaded If the jaw does not snap back into position Loosen the screws that hold the top bearing in place Clamp the part and re tighten the screws Run a test part to ensure that the issue has been resolved e If you hear a noise similar to a clunk during actuation this could be an indica tion your drawbar has become loose and is not secure BA Nr UBL ABL E SET UP AND
