STARTING THE ENGINE
Attempting to start the engine incorrectly or using the pressure washer incorrectly can
result in engine and/or pressure washer damage, and may cause serious injury or death.
To avoid these hazards, be sure to read, understand, and follow the steps outlined in the
OPERATING CHECKLIST section of the owner’s manual before starting the engine, and
follow all the guidelines for proper use of the pressure washer.
OPERATING CHECKLIST
Running the pressure washer for more than two minutes without the spray gun trigger
pulled will overheat the pump and possibly cause damage. The thermal relief valve will
open and spray water to help cool the pump as it overheats. To avoid overheating the
pump, shut o the machine if not being used for longer than two minutes.
