This product must be grounded. If it should malfunction

or break down, grounding provides a path of least

resistance for electric current to reduce the risk of electric

shock. This equipment 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.

Improper connection of the 

equipment–

grounding conductor can result in the risk of

electrocution. Check with a qualified electrician or

service person if you are in doubt as to  whether

the outlet is properly grounded.

To comply with the National Electrical Code (NFP A 70)

and to provide additional protection from the risk of

electric shock, connect this pressure washer to a  circuit

that is protected by a ground–fault circuit–interrupter

(GFCI).

Any misuse of the pressure washer or accessories, such

as overpressurizing, modifying parts, using incompatible

chemicals and fluids, or using worn or damaged parts,

can cause them to rupture and result in fluid injection,

splashing in the eyes or on the skin, or other serious

bodily injury, fire, explosion or property damage.
NEVER alter or modify any part of this equipment; doing

so could cause it to malfunction.
CHECK all spray equipment regularly and repair or

replace worn or damaged parts immediately.

clothing.  If using a chemical injector, read and follow the

chemical manufacturer’s literature for recommendations

on additional protective equipment, such as a respirator.
