Maintenance Schedule

To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

The operating conditions of your particular system determine how often maintenance is required.  Establish a preventative maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.

  • Flush the system.
  • Clean hopper with a scrub pad.
    • It is recommended that you clean the outside of the sprayer using a cloth and water.
  • Check hoses, tubes and couplings for wear, damage and leaks.
  • Tighten all fluid connections before each use.
  • Check and replace cam-lock gaskets as needed.
  • Check the cam lock connections for damage (dings, nicks, cracks) replace if necessary.
  • Check fluid drain/purge valve for proper operation.
    • Clean/flush the valve if necessary.
  • Check level of Throat Seal Liquid (TSL) in displacement pump packing nut/wet cup.
    • Fill nut 1/2 full with TSL.
    • Maintain TSL level to help prevent material buildup on piston rod and premature wear of packings and pump corrosion.
  • Break down the pump lower and thoroughly clean and inspect check balls.
    • This can either be done daily or when changing material.
  • Grease swivel fittings on the applicator.
  • Break down the pump lower and thoroughly clean and inspect all wear components.
    • Check balls.
    • Piston.
    • O-rings.
    • Seats.
  • Always flush pump before the fluid dries on the displacement rod.
    • First, flush with water, then with oil. 
    • Relieve the pressure, but leave the oil in the pump to protect the parts from corrosion.
  • To prevent rust, never leave water or water-based fluid in the pump overnight.
  • Material left on the throat seal can dry out and damage the seal.
  • Always stop the pump at the bottom of the stroke to avoid damage to the throat seal.
  • Always flush the pump before the fluid dries on the displacement rod.
    • First, flush with water, then with oil. 
    • Relieve the pressure, but leave the oil in the pump to protect the parts from corrosion.
  • Exposing the motor and/or control to water can cause damage and possible motor failure.
  • Do not store the pump outside.
  • Do not spray water directly into the motor fan.
