adapter of the extruder. A standard (0.005”) shim is factory-installed on your extruder.
Two additional cut shims are included, along with three blank shims.

2. Turn the ASU’s pump/ motor OFF.
3. Switch the unit voltage-free and pressureless.
4. Guard the unit against unauthorized restarting.

CAUTION
Take care not to scratch or nick the mating surfaces of the parts of die lip set
during this procedure.

plate adapter without damage to the assembly.

solvent. Pay special attention to the surfaces that clamp the shim.
