  1. Always verify the GPM output of the supply hose is adequate for machine.  Check supply filter.
  2. Always check engine and pump for proper level and color of oil before every use.
  3. Always shut unit down when letting go of the gun jet more than 30 – 45 seconds.
  4. Always change oils regularly every 250-300 hours of use (pump and engine).
  5. Always shut down burner first, run for 1-2 minutes or until cold, and then shut the engine down. (Applicable only to hot water units).  Always run at full throttle while burner is on.
  6. Always make sure supply valve (house or jobsite) is open all the way.
  7. Always get valves adjusted every 300 hours or warranty is void.
  8. Always run antifreeze through unit during the winter months, and if more than two months will elapse between uses.  If using during freezing temperatures, run antifreeze immediately after each use.


  1. Never walk away from a unit while running in by-pass for more than 45 seconds.
  2. Never kink supply or high pressure hose, or run over with a car or forklift.
  3. Never run a unit with water leaks anywhere on the machine (gun jet, hose, fittings, etc.).
  4. Never continue to run a unit with milky or metallic oil.  Running a unit until it quits just to finish a job is costly.
  5. Never throttle down an engine while the burner is running, or shut down a unit while the burner is on.
  6. Never tip a machine over or run it at an angle: the oil will not properly lubricate the internal parts.
  7. Never allow the unit to freeze.  Just blowing out water will still leave enough water in the unit to cause major damage when the unit freezes.
