GENERAL
• Read all instructions. Read and understand this Owner’s Manual and the engine Owner’s
Manual completely before attempting to set-up and use the pressure washer. Serious injury or
death can result if safety and other instructions are not followed.
• Instruct all operators. The pressure washer’s owner must instruct all operators and potential
renters in safe pressure washer set-up and operation. Do not allow anyone to operate the pressure
washer who has not read the Owner’s Manual and been instructed on its safe use. Owner’s
Manuals are available from NorthStar at 1-800-270-0810.
• Adult control only. Only trained adults should set up and operate the pressure washer. Do not let
children operate. Pressure washers can generate forces greater than children can control and
require judgment beyond what can be expected of children.
• Under the influence. Never operate, or let anyone else operate, the pressure washer while
fatigued or under the influence of alcohol, drugs, or medication.
• Understand intended use. Carefully read about and understand the intended use of this pressure
washer. Do not use for other purposes, as unforeseen hazards or equipment damage may result.
PROHIBITION AGAINST MODIFICATIONS
Never modify or alter the pressure washer in any way or deactivate any safety device. Modifications
can create serious safety hazards and will also void the warranty.
• Fuel/exhaust system. Never add to or modify the exhaust system, fuel tank, or fuel lines. Carbon
monoxide poisoning, fuel leaks, fire or explosion could result.
• Unloader valve. Do not attempt to alter the unloader valve’s maximum pressure. Excess pressure
could cause serious injury from escaping high-pressure fluids and/or pump damage. Any alteration
other than turning the adjustment knob will void your warranty.
• Guards. Do not operate pressure washer unless all guards and cover shields are in place.
SAFETY – INSTALLATION & SET-UP
Installation / Initial Set-up
• Level, heat-resistant surface. Situate pressure washer on a firm, level, and heat-resistant surface
with good drainage. Ensure it sits level and will not slide or shift during operation. Block wheels to
prevent movement.
• Prevent carbon monoxide poisoning – Use outside only! Exhaust fumes from both the engine and
the burner contain carbon monoxide (CO), a poisonous gas you cannot see, smell, or taste. The CO
generated by the pressure washer can rapidly accumulate, even in areas that appear to be well
ventilated, resulting in dangerous and fatal concentrations within minutes. To prevent dangerous
CO build-up:
