11. PRIMARY KEY FUNCTIONS Maintenance Measurement Table Kits will operate in a dry environment with non conductive debris such as sawdust plastic dust etc with no adverse effects The system should be cleaned of excess debris when necessary This will prevent premature damage to the Scale or ReadHead Should the Sliding assembly become difficult to move check to see if debris has built up under the ReadHead and remove if necessary Find and remove any burrs which may have developed on the aluminum Scale Do not use any liquid lubricants on the assembly as this may impede the sliding assembly s ability to operate properly and could attract other contaminants to the system as well as swell the black bearings on the moving assembly thus making it tighter and harder to move along the scale The Display should be cleaned periodically with compressed air to remove any dust on the lens and keys All mounting fasteners should be checked occasionally for tightness Occasionally check parallelism of the jaws by measuring a thick piece of paper between the upper side of the jaw then between the lower side of the jaw A variation of 0 05mm 0 002 inches is acceptable Adjust the black Measurement Table Kit Page 9 of 28 bearings if necessary Should the assembly become difficult to move check to see if the scale is clean Find and remove any burrs which may have developed on the aluminum scale Changing the Batteries A low battery indi
