4.Spray detergent onto the surface and allow it to soak. Chemicals need time (dwell time) to work properly.

Follow the chemical manufacturer’s recommendations for dwell time.

5.Change back to high pressure by rotating the grip until water comes out the right lance only.

6.Hold the lance with two hands, have a sturdy stance.

7.Point lance at dirty surface and squeeze trigger.

8.Wash from the bottom to the top, using side to side motions. This washes away heavy dirt and allows the detergent to soak as you work toward the top.

9.Use the width of the spray pattern to wash in a wide path. Overlap spray paths for complete coverage.

10.The nozzle should be 12” to 24” from the work, closer for tough areas.

Caution: Be careful on painted or delicate surfaces, the pressure may damage the surface if the nozzle is too close.

11.Small parts should be washed in a basket so the pressure does not push them away. Larger, light weight parts should be clamped down.

12.The pressure washer is set to the maximum rated pressure when it leaves the factory. There are two easy ways to change your pressure.

a. Rotate the grip slightly to allow some flow to pass through the left lance. See step 3.

WARNING: Do not alter the unloader valve’s maximum pressure. Excess pressures could cause serious injury and/or pump damage. Any alteration other than turning the adjustment knob will void your warranty.

For Steam (Optional)

1.Set the thermostat to 250°F.

2.Turn the Heat switch ON.

3.Insert the steam nozzle into the nozzle holder.

To Stop

1.If detergents were used, draw clear water through the detergent inlet line to purge detergent. Failure to do so may clog the chemical injector.

2.If the burner was used, turn off the “Heat” switch and pump cold water through the coil for 3 minutes. Insufficient cool down period of high pressure hose will cause excessive wear and eventual rupturing of hose.

3.Turn the pump switch OFF.

4.Turn OFF the water supply.

5.Squeeze the trigger to relieve the system pressure.
