WATER SUPPLY 
(Cold Water Only)

CAUTION

When connecting the water inlet to the water 
supply mains, local regulations of your water 
company must be observed. In some areas 
the unit must not be connected directly to the 
public drinking water supply. This is to ensure 
that there is no feedback of chemicals into the 
water supply. Direct connection via a receiver 
tank or backflow preventer, for example, is 
permitted.

Dirt in the feed water will damage the unit. To 
avoid this risk, we recommend fitting a water 
filter.

„

Garden hose must be at least 1 inch in 
diameter.

„

Flow rate of water supply must not fall 
below 2.6 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 140°F/60°C.

„

Never use the pressure washer to draw in 
water contaminated with solvents, e.g. 
paint thinners, gasoline, oil, etc.

„

Always prevent debris from being drawn 
into the unit by using a clean water source.

CANADA:

Injection hazard: equipment can cause 
serious injury if the spray penetrates the skin. 
do not point the gun at anyone or any part of 
the body. In case of penetration seek medical 
aid immediately.

 

This system is capable of producing 
13700 kPa /2000 PSI to avoid rupture and 
injury, do not operate this pump with 

components rated less 13700 kPa /2000 PSI 
working pressure (including but not limited to 
spray guns, hose and hose connections).

Before servicing, cleaning or removing any 
parts, shut off power and relieve pressure

.

identified by the marking “Acceptable for 
use with outdoor appliances; store indoors 
while not in use.”

„

Use only extension cords having an 
electrical rating not less than the rating of 
the product.

„

Do not use damaged extension cords.
