  • Page 40: Lubrication & Maintenance

    HIGHWAY EQUIPMENT COMPANY LUBRICATION & MAINTENANCE PREVENTATIVE MAINTENANCE PAYS! The handling and spreading of commercial fertilizers is a most severe operation with respect to metal corrosion. Unless a frequent, periodic preventative maintenance program is established, rapid damage to spreading equipment can occur. Proper cleaning, lubrication and maintenance will give you longer life, more satisfactory service and more economical use of your equipment.

  • Page 41: Hydraulic Hose

    HIGHWAY EQUIPMENT COMPANY LUBRICATION & MAINTENANCE CONTINUED HYDRAULIC HOSE Hose assemblies in operation should be inspected frequently for leakage, kinking, abrasion, corrosion or any other signs of wear or damage. Worn or damaged hose assemblies should be replaced immediately. Clean Clean assembly by blowing out with clean compressed air.

  • Page 42: Conveyor Chain

    HIGHWAY EQUIPMENT COMPANY LUBRICATION & MAINTENANCE CONTINUED CONVEYOR CHAIN Hose down unit and remove any material build-up on sprockets and under chain.

  • Page 45 HIGHWAY EQUIPMENT COMPANY LUBRICATION & MAINTENANCE CONTINUED PROBLEM 2: (Figure 12) Belt contacts one side at front and contacts other side at rear. SOLUTION: If adjusting as in Problem 1 does not remedy the situation, adjustment of the drive pulley is necessary. Mark the position of the adjustment screw (RH side) on the side of the unit.
  • Page 46 HIGHWAY EQUIPMENT COMPANY LUBRICATION & MAINTENANCE CONTINUED If, after continued adjustment, the belt does not track properly, check the following: 1. Check for twisted spreader body. Shims must be placed between spreader cross tubes and the mounting surface to eliminate any twist in the body structure. 2.
