OPERATION
1. Make sure the Power Switch is in the “OFF” position. Attach the heavy duty
hose to the Pressure Washer, using the Heavy Duty Hose Adapter (G).
3. Attach the Spray Lance (K) or Detergent Bottle (H) into the Spray Wand Extension
(I), and press and twist the Wand into the Extension until the Wand locks in place.
(See Figure C, page 10.)
NOTE: The Pressure Washer will not pressurize if the Nozzle is not completely
assembled. It will not work properly with only part of the Wand installed.
4. Connect the High Pressure Hose (26A) to the Pressure Washer. (See Figure D.)
Make sure all connections are tight. Then, open the water supply valve fully. If
leaks occur, shut off water and retighten connections.
5. IMPORTANT! Prior to turning on the Pressure Washer, connect the unit to the
water supply. Turn on the water, disengage the safety, and squeeze the Trigger
(23A) until water flows out of the Gun Assembly (E) without sputtering. This
removes air from the system and allows the unit to properly perform. Failure to
follow this step can damage the Pump.
6. Test the cleaning capabilities and the run before starting your cleaning project, as
explained on page 16, #1. Turn the Power Switch to the “ON” position. The motor
will briefly run when the switch is first turned on to build up pressure and then
go to standby until the trigger is squeezed. DO NOT ALLOW THE UNIT TO REMAIN
IDLE FOR MORE THAN A MINUTE OR TWO; the unit will build up heat when it
is on standby mode.
7. Point the Nozzle in a safe direction. Then, disengage the Safety and squeeze the
Trigger (23A). Switch the unit’s switch to the OFF position whenever the gun is not
in use. Clean the area, following the tips contained in the Operating Tips section.
8. When finished spraying, fully engage the Trigger Safety Lock (25A), turn the Power
Switch to its “OFF” position, and turn off the water supply.
WARNING: Do not disconnect the high-pressure hose or water inlet hose
until all pressure is discharged safely.
9. IMPORTANT! When turning off the unit after use, high pressure will remain inside
the unit its High Pressure Hose (26A), and the water inlet hose. Point the Gun
Assembly (E) in a safe direction and hold the trigger down for several seconds.
Then, release the Trigger (23A) and remove the Spray Wand Extension (J). Hold the
Trigger until water stops flowing from the gun. The high-pressure hose and water
inlet hose can be disconnected after the pressure is released.
10. Store the pressure washer and all accessories in accord with the directions under
Storage on page 17.
