ring. When the trigger of the trigger gun is released or
when the thermostat temperature setting is reached,
the burner will automatically turn off.
IMPORTANT: If ignition or flame failure is experienced,
discontinue use of pressure washer at once. Turn off
burner and shut off fuel supply. Have cause of failure
corrected by an authorized service technician before
use of pressure washer is continued.
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 7. The 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
have performed maintenance on the burner assembly,
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.
