Maintenance： Pay attention to the dustproof work in the working environment. The #20 machinery oil should be applied to the shaft to keep a certain film of oil on the working surface. The running part of the reversal springs should be lubricated for protection. Reversal Failure： In case the reversal is too show or not available, push and check the reversal arm for swivelling blockage so as to eliminate the fault. If the elasticity is insufficient, change the reversal spring and lubricate the bearing point of spring. Inadequate Thrust： Adequately screw clockwise the screw plugs in the center of the top and/or in the side edge of the bottom of the drive housing until the traverse thrust required is available. Too tight adjustment of screw plugs often causes improper reversal and may lower the operating life of the drive unit. Uneven Traversing： The eccentric sleeve on the back side wall of the housing is required. It is usually fastened by set screws. Loosen the screws first to make a slight adjustment, and screw them tight again after the left-handed and right-handed travel pitches are identical.
