Page 13: Maintenance
MAINTENANCE GREASE DRIVE GEARS The recommended lubricant is Castrol Molub-Alloy 777-1 or equivalent. Apply grease to all drive gears after every 40 hours of operation. If the machine is to be used in a damp environment, apply a film of oil or grease to all unpainted metal surfaces to prevent rust. CLEANING THE ROLLS Keeping the forming rolls clean is an important step toward efficient operation of your machine. -
Page 14: Trouble Checks
IMPROPERLY FORMED/DEFORMED EDGES -It may be necessary to add a slight lubricant to the surface of the sheet being formed to aid the flow of material through the forming rolls. Lockformer’s GALV-OFF available from FORMTEK is recomended. -The operator may have to experiment with hold down settings for desired results. Run test pieces to check different settings on the hold down nuts or bolts. - Page 15 require exit gauge pressure along the materials edge such as long heavy pieces where an awkward weight and size make it difficult for the operator to hold the piece straight during the forming process. This technique must be used carefully. Other conditions may be causing the runnout, such as loose settings on the hold downs or improperly adjusted entrance gauges (those settings should always be checked first).
