3. With hose still attached to the formulation tank, unscrew the hose and draw tube assembly
from the formulation tank and place into a graduated cylinder. Reconnect the tube from the
nozzle to the top of the orifice fitting.
4. Add chemical to the graduated cylinder until well above the bottom of draw tube and note
volume in the cylinder.
5. Turn engine ignition on and pull start engine. Let engine warm for at least 30 seconds to one
minute. If engine at idle, increase engine throttle manually until pressure gauge reads
approximately 80 PSI.
6. Ensure the top of the draw tube is close to the same height as it would be if attached to the
formulation tank. Note: if the draw tube is higher or lower than it would be normally, this can
skew the results and cause inaccurate flow calibration.
7. Open the spray valve on the rear side of the nozzle either manually or electrically if that option
is installed. Let spray for exactly 1 minute using a stop watch then turn spray valve off.
8. Read remaining volume in graduated cylinder (note: do not remove the draw tube) and subtract
that number from that which was noted in step 4. This is your flow per minute based on the
orifice size selected.
9. Increase or decrease orifice size and repeat these steps until reaching the desired flow results.
10. When Flow calibration is complete, reinstall the draw tube back into the formulation tank and
ensure all connections are secure.
