If power is interrupted in the line, the GFCI will automatically reclose the circuit to the load after power is restored. Depending on the GFCI model, it may be necessary to manually operate the reset button to restore power to the GFCI load circuit. If replacement of the plug or cord is needed use identical replacement parts.
WATER SUPPLY (Cold Water Only)
CAUTION
Dirt in the feed water will damage the unit. To avoid this risk, we recommend fitting a water filter.
!
Water hose must be at least 5/8 inch in diameter.

Flow rate of water supply must not fall below 2 GPM (gallons per minute).
!
!
!
!
Flow rate can be determined by running the water for one minute into an empty 5-gallon container.
The water supply temperature must not exceed 104°F/40°C.
Never use the pressure washer to draw in water contaminated with solvents, e.g. paint thinners, gasoline, oil, etc.
