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.
  • Relieve pressure.
  • 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 hydraulic oil level and fill as necessary.
  • Check compressor oil level and fill as necessary. 
    • Compressor oil should be replaced after 50 hours (break-in) and every 200 hours after initial oil change. 
    • If the compressor oil is dark black and shows sediment before the 200 hour time period is complete, replace the oil.
    • If the red dot on the compressor sight glass is visible, add oil.
  • Inspect hydraulic and fluid lines for leaks.
  • 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. 
    • Fill nut, if necessary. 
    • Keep TSL in nut to help prevent material buildup on piston rod and premature wear of packings and pump corrosion.
  • If operating in an unusually dusty environment, check the filter daily and replace if necessary.
  • Remove compressor air filter cover and clean element. 
    • Replace the element if necessary.
  • Check the hydraulic fluid level weekly using a dipstick. 
    • The fluid level must be between the marks on the dipstick. 
    • Refill as required with approved hydraulic fluid (see Technical Specifications, in manual). 
    • If the fluid is dark in color, change the fluid and filter. 
  • Replace break-in oil in a new unit after the first 250 hours of use or within 3 months, whichever comes first. 
  • See the table below for recommended frequency of oil change.

  • Clean the pre-filter and muffler on the air compressor air relief valve. 
  • Replace the air relief valve (part 17H606) and muffler (part 120206) if necessary.
  • Check belt wear. 
  • Replace if necessary.
  • 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.
