IMPORTANT: The trigger gun provided with this pres-
sure washer is equipped with a manual trigger lock to
prevent accidental operation of the trigger gun, refer
to figure above. The safety trigger lock should be used
whenever the trigger gun is not in use.
IMPORTANT: On initial start-up or if maintenance
has been performed on the burner assembly, it will
be necessary to bleed the air from the gas line before
the pilot will light.
7. If you are running the machine for the first time, or

there will be air in the gas line. To bleed the air from
the gas line run the pressure washer with pump and
burner switches on and thermostat on highest setting.

spill out on the floor in the 2 to 3 minutes required for
the safety pilot valve to close off gas supply. There-
fore, always provide adequate space and ventilation
around these units.
