6. MAINTENANCE
6.1 MAINTENANCE SAFETY
1. Stop engine, remove spark plug wire, relieve internal pressure and wait for all moving parts to stop
before servicing, adjusting or repairing.
2. Relieve the internal pressure before any maintenance to the spraying system.
DANGER!
1. Do not refuel while smoking or when near an open flame or sparks.
2. Allow engine to cool for 2 minutes before refueling.
3. Stop engine before refueling. Clean up spilled fuel before restarting engine.
6.2 PREVENTATIVE MAINTENANCE
This section includes instructions for preventative maintenance on your pressure washer. Follow the anti-
freezing instructions if your equipment might be subjected to freezing temperatures. Other preventative
maintenance instructions apply to all machines.
6.2.1 ANTI-FREEZING THE PRESSURE WASHER (WINTERIZING)
Frozen water inside the pump will ruin components such as the plunger seals. Follow these winterizing steps
whenever the pressure washer must be stored in freezing temperatures.
1. Be sure machine is OFF, water supply is disconnected and pressure has been relieved.
2. Obtain a one-gallon container of anti-freeze. Using 100% anti-freeze in the pump is OK.
3. Use compressed air and blow through the inlet of the gun to remove residual water. NOTE: the trigger
on the spray wand must be held open while applying pressure.
4. Remove the nozzle from the wand and lay the hose and wand flat on the floor.
5. Place a suction hose from the pump inlet into the anti-freeze. Hold the spray gun trigger open. Turn
the pump ON to draw anti-freeze into the system. When anti-freeze appears at the end of the spray
wand, turn the pump OFF.
6. When preparing to operate the equipment next time, remove the anti-freeze as follows:
a. Reconnect the water supply.
b. Turn the pump on.
c. Spray water to flush the system. Continue until the water stream is clear of any anti-freeze.
