Operating Instructions and Parts Manual
Operation (Continued)
4. Turn the water supply ON.
Never run the unit dry. Be sure the water supply is completely turned on before operating the unit.
5.Trigger the gun until water sprays from the tip indicating that all air is purged from the system. Set the trigger safety latch.
6.Plug the power cord into a grounded 120V outlet, that is on a dedicated circuit. Press the reset button on the GFCI plug adapter. This must be done each time the unit is plugged into an outlet.
System Connection
1.Insert lance into the gun and turn clockwise to positive stop as shown in Figure 19.
2.Attach the high pressure hose onto the gun by turning clockwise and tighten with a wrench.
3.Be sure that the power switch is in the “OFF” position.
4.Attach the high pressure hose onto the pump water outlet by turning clockwise and hand tightening.
5.Connect garden hose as explained under Garden Hose Connection Instructions.
6.Plug the power cord into a grounded 120V outlet.
7.Turn water on.
8.Unlock trigger lock by moving lock right to left.
9.Depress and hold the trigger on the gun for one minute to release pressure and remove any air trapped in the system.
10.Turn the “ON/OFF” switch to the “ON” position.
Initial High Pressure Rinse
Spray the cleaning surface with water to clear off any dirt or grime that may have collected on the surface. Doing so allows the detergent to attack the deep down dirt that has worked its way into the cleaning surface.
Trigger the gun 3 to 5 times to get any trapped air out of the system.
Adjusting the Spray Fan Angle
1.The lance is affected by pressure during operation; therefore hold it firmly with both hands and point the nozzle toward the ground.
2.Activate by pulling the trigger of the gun/spray handle.
3.Adjust the distance to the cleaning surface, which will also adjust your pressure of the nozzle.
4.Spray pattern shape and intensity can be changed by twisting the spray adjuster at the end of the lance (see Figure 21). Keep hands clear of the front of the lance to prevent injury.
Pressure can also be adjusted by moving closer or further away from the cleaning surface and by adjusting the spray fan angle as shown.
Angle to the Cleaning Surface
When spraying water against a surface, you can generate maximum impact by striking the surface head on. However, this type of impact can cause dirt particles to embed in the surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning surface is 45 degrees.
Spray water against a surface at a 45 degree angle to achieve the most beneficial impact force and to efficiently remove debris.
