TEM SHALL BE PROTECTED  
AGAINST BACKFLOW.  
ƽ 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 con-  
nected directly to the public drinking wa-  
ter 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.  
SERVICING OF A DOUBLE-  
INSULATED PRODUCT  
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.  
In a double-insulated product, two sys-  
tems of insulation are provided instead  
of grounding. No grounding means is  
provided on a double-insulated product,  
nor should a means for grounding be  
added to the product. Servicing a dou-  
ble-insulated product requires extreme

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.  
GROUND FAULT CIRCUIT INTER-  
RUPTER PROTECTION  
This pressure washer is provided with a  
ground-fault circuit-interrupter (GFCI)  
built into the plug of the power-supply  
cord. This device provides additional  
protection from the risk of electric shock.
