Safety Warnings  
receptacle before disconnecting the  
product from the extension cord. If you are  
using an extension cord, it should always  
be completely unwound from the cable  
drum.  
When using this product, basic precau-  
tions should always be followed:  
• Read all the instructions before using  
the product.  
• High pressure jets can be dangerous  
if subject to misuse. The jet must not  
be directed at persons, animals,  
electrical devices, or the machine itself.  
To reduce the risk of injury, do not  
operate the machine near children.  
Ground Fault Circuit Interrupter  
(GFCI) Protection  
This unit is supplied with a portable  
Ground Fault Circuit Interrupter (GFCI).  
UL indicates that the power cord has been  
investigated for compliance with the  
applicable provisions of UL 943, Third  
Edition (Standard for Ground Fault Circuit  
Interrupters) and other applicable  
standards. 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.  
• Learn how to stop the machine and  
release pressure quickly. Be thoroughly  
familiar with the controls.  
• Stay alert — watch what you are doing.  
• Wear safety goggles.  
• Do not use acids,  
solvents, or any  
flammable material in this product.  
These products can cause physical  
injuries to the operator and irreversible  
damage to the machine.  
• Do not operate the product when  
fatigued or under the influence of  
alcohol or drugs.
