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 or leaks.
  • Tighten all fluid connections before each use.
  • Check and replace cam-lock gaskets as needed.
  • Check the hose for wear and damage, and inspect fluid lines for leaks.
  • Check fluid drain/purge valve for proper operation.
  • 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.
  • Remove and clean the inlet tube assemblies to prevent material buildup. 
    • Failure to do so can reduce pump performance and cause it to lose prime while pumping.
  • To prevent rust, never leave water or water-based fluid in the pump overnight.
  • 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.
  • If the pressure relief valve on the F800e system is ever activated due to over-pressure, it must be removed, disassembled and thoroughly cleaned of fireproofing material.  Failure to do so could result in the relief valve not functioning if an over-pressure situation were to again occur.  Although it is a rare event for the valve to be activated due to over-pressure, it is important it be cleaned if it does occur.
