When using this product, basic precautions
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.
• 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.
• Keep operating area clear of all persons.
• Do not stand on unstable surfaces.
Stand with both feet balanced at all times.
• 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.
Extension Cords
Use a sufficient gauge: Up to 25 ft. = 12/3 AWG;
25 to 50 ft. = 10/3 AWG. Use only
extension cords that are intended for outdoor
use. These extension cords are identified by the
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. If you are using an extension cord, it should always be completely unwound from the cable drum.
Ground Fault Circuit Interrupter
(GFCI) Protection
This product is supplied with a Ground Fault Circuit Interrupter (GFCI) built into the power cord
plug. This device provides additional protection
from the risk of electric shock. If power is interrupted in the line, the GFCI will automatically
re-close 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. If
replacement of the plug or cord is needed use
identical replacement parts.
Grounding Instructions
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 equipmentgrounding 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.
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 adapter with this product
