This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection and
splashing, keep fingers and other body parts away
from the spray tip.
To avoid injury from toxic fluids or fumes, such as
splashing in the eyes or on skin, wear appropriate
personal protective equipment.
1. Prepare several cups.
2. Weigh one cup and record the weight.
3. Dispense into a waste container to prime the PSM
machine.
4. Place the cup under Dispense Valve (AB, page 8)
and cycle the machine one time.
5. Repeat by using a cup each time.
6. Re-weigh all cups and record weights.
7. Subtract weight of empty cups from weight of filled
cups to get material weights.
