Page: 18 / 55

START FOGGING
1. Start the engine as specified in the section STARTING THE ENGINE.
2. Verify that the formulation Tank Cap is tight.
3. When the engine is running smooth:
Model 2620 – (1) Pull open the automatic shutoff - valve stem.
(2) Rotate the 3-way selector valve lever to the fog position.
Model 2630 – Rotate the 3-way selector valve lever to the fog position.
4. Once these conditions have been met, the fog can be started and stopped by rotating
the 3-way selector valve lever to the fog and purge positions.
As a safety feature, the model 2620 Blackhawk is equipped with an automatic formulation shut-off
valve. If the machine stops running for any reason, including running out of fuel, the shut-off valve
will instantly close, preventing formulation from being forced into the engine tube by the air pressure
in the formulation tank.
After fogging, always adjust the 3-way valve to the flush position. This will help prevent the
formulation line from clogging, and help prevent any formulation that may remain in the lines from
igniting and causing a fire.
