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 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.
