Maintenance Schedule

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.
