Pneumatic Operation
Volume Adjuster
The volume adjuster can be used in different modes:
Low pressure
With the selector valve set to vent (open), turn the volume adjuster
fully anti-clockwise (out).
Turn the selector valve to the fully clockwise (in) position to select
pressure.
Turn the volume adjuster clockwise to generate pressure.
High pressure
Turn the volume adjuster to the mid-position. In this position fine
adjustments of the generated pressure can be made. Using the
scissor-action handles, generate the approximate pressure; then
turn the volume adjuster clockwise (in) to increase the pressure or
turn the volume adjuster anti-clockwise (out) to decrease the
pressure.
Vacuum
Turn the selector valve fully anti-clockwise (out) position.
Turn the volume adjuster to the mid-position. In this position fine
adjustments of the generated vacuum can be made.
Using the scissor-action handles, generate the approximate
vacuum; then turn the volume adjuster clockwise (in) to decrease
the vacuum or turn the volume adjuster anti-clockwise (out) to
increase the vacuum.
For low vacuum use the volume adjuster only.
