- 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.
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.
- 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.
- 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.
