IMPORTANT PRECAUTIONS – Read First!  
Safety Warnings  
GROUNDING INSTRUCTIONS  
When using this product basic precautions  
should always be followed:  
This product must be grounded. If it should  
malfunction or breakdown, grounding provides  
a path of least resistance for electric current to  
reduce the risk of electric shock. This product  
is equipped with a cord having an equipment-  
grounding conductor and a grounding plug. The  
plug must be plugged into an appropriate outlet  
that is properly installed and grounded in  
accordance with all local codes and ordinances.  
• 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.  
• 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 other  
flammable material in this product. These  
products can cause physical injuries to the  
operator and irreversible damage to the  
machine.  
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 installed by a qualified electrician.  
Do not use any type of adaptor with this product.  
• Do not operate the product when fatigued or  
under the influence of alcohol or drugs.  
• Do not stand on unstable surfaces. Stand with  
both feet balanced at all times.  
Extension Cords  
Use a sufficient gauge:  
Up to 25 ft = 12/3 AWG  
To reduce the risk of electrocution, keep all  
connections dry and off the ground. Do not  
touch plug with wet hands.  
• The Trigger Gun Safety Lock PREVENTS the  
trigger from accidentally being engaged. This  
safety feature DOES NOT lock trigger in the  
on position.  
25 to 50 ft = 10/3 AWG  
Use only 3-wire extension cords that have 3-  
prong grounding-type plugs and 3-pole cord  
connectors that accept the plug from the  
product. Use only extension cords that are  
intended for outdoor use. These extension  
cords are identified by a 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. Examine extension cord before  
using and replace if damaged. Do not abuse  
extension cord and do not yank on any cord to  
disconnect. Keep cord away from heat and  
sharp edges. Always disconnect the extension  
cord from the receptacle before disconnecting  
the product from the extension cord.

IMPORTANT PRECAUTIONS – continued  
Water Supply (Cold Water Only)  
• Never use the pressure washer to draw in  
water contaminated with solvents, e.g.  
paint thinners, gasoline, oil, etc.  
NOTE: 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 a 1/2 inch or  
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.  
• Always prevent debris from being drawn into  
the unit by using a clean water source and an  
accessory water filter if required.
