tension and other factors will ultimately determine the
proper material pressure that will be required.
• GlasCraft recommends an initial start-up pressure of
20-25 psi.
3. Dial up material pump pressure to initial start-up
pressure.
4. Prime the slave pump to proper psi. depending on
which gun is being used.
5. Rotate Pivot Knob, P/N SSP-159 to Re-engage
catalyst drive arm.

• Because of material viscosity, size of nozzle, hose length
and other factors, the catalyst pressure may not exactly
exactly match material pressure.
• Catalyst pressure should be +/- 50 psi of material
pressure.
