ble support. Keep good footing and  
balance at all times.  
Do not touch plug with wet hands.  
Do not use extension cord with this  
product.  
Follow the maintenance instructions  
specified in the manual.  
Connect to individual branch circuit

This product is provided with a  
Ground Fault Circuit Interrupter built  
into the power cord plug. If replace-  
ment of the plug or cord is needed,  
use only identical replacement parts.  
ƽ CAUTION  
This unit has been designed for use with  
cleaning detergents recommended by  
the manufacturer. The use of other  
cleaning detergents may affect the op-  
eration of the machine and void the war-  
ranty.  
ƽ WARNING  
Risk of Injection or Injury – Do Not  
Direct Discharge Stream At Per-  
sons.

Do not spray electrical apparatus and  
wiring.  
Do not use with flammable liquids and  
toxic chemicals.

shock. Should replacement of the plug  
or cord become necessary, use only  
identical replacement parts that include  
GFCI protection.  
WATER SUPPLY  
(Cold Water Only)  
Before servicing, cleaning or removing  
any parts, shut off power and relieve  
pressure.  
ƽ CAUTION  
When connecting the water inlet to the wa-  
ter supply mains, local regulations of your  
water company must be observed. In some  
areas the unit must not be connected di-  
rectly 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 1/2  
inch or 5/8 inch in diameter.  
Flow rate of water supply must not  
fall below 2 GPM (gallons per  
minute).  
GROUNDING INSTRUCTIONS  
This product must be grounded. If it  
should malfunction or breakdown,  
grounding provides a path of least resis-  
tance for electric current to reduce the  
risk of electric shock. This product is  
equipped with a cord having an equip-  
ment-grounding conductor and a  
grounding plug. The plug must be  
plugged into an appropriate outlet that is  
properly installed and grounded in ac-  
cordance with all local codes and ordi-  
nances.  
ƽ DANGER  
Improper connection of the equipment-  
grounding conductor can result in a risk  
of electrocution. Check with a qualified  
electrician or service personnel if you  
are in doubt as to whether the outlet is  
properly grounded. Do not modify the  
plug provided with the product - if it will  
not fit the outlet, have a proper outlet in-  
stalled by a qualified electrician. Do not  
use any type of adapter with this prod-  
uct.  
Flow rate can be determined by run-  
ning 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 sol-  
vents, e.g. paint thinners, gasoline,  
oil, etc.  
Always prevent debris from being  
drawn into the unit by using a clean  
water source.
