OPERATING INSTRUCTIONS
The power washer will pull a ratio of water to detergent of
10:1 or 10 parts water to 1 part detergent. The detergent
concentration can be adjusted by turning the detergent
knob on the front of the machine. Turn it right for more
concentration or turn it left for less concentration.
Operation Tips
•
If you hear the motor run intermittently when the trigger is not being squeezed, that is normal.
The pump is priming itself so it is ready to operate when the trigger is squeezed. Turn off the power
washer if not being used after five minutes.
• The o-rings on the bayonet end of the nozzle should be cleaned regularly and lubricated with non-
water soluble grease such as petroleum jelly.
• Keep the nozzle cleaning wire for use in unclogging the nozzle. If you lose the cleaning wire, a
straightened paper clip also works.
How to Avoid Damaging Surfaces
• Damage to surfaces being cleaned occurs because the impact force of the water pressure exceeds
the durability of the surface. Bare wood can be penetrated; paint can be peeled off, etc. You can
vary the force of your power washer by controlling:
1. The angle of the surface being cleaned
2. The distance of the nozzle from the surface being cleaned
•
NEVER
use a narrow high pressure stream of water on soft surfaces susceptible to damage.
• Use the 25˚ angle quick connect nozzle when cleaning windows. Be sure to place the nozzle
approximately four to five feet away from the window with the nozzle at forty five degree angle.
Squeeze the trigger and vary the spray pattern and angle until optimum cleaning efficiency is
achieved.
