DIAPHRAGM INSPECTION and REPLACEMENT

WARNING:

NEVER ATTEMPT TO REMOVE

DIAPHRAGM WITH METAL OBJECTS

PROBE DIAPHRAGMS

The probe mechanism is protected from coolant

and debris by two diaphragms, these provide

adequate protection under normal working

conditions.

The user should periodically check the outer

diaphragm, for signs of damage and coolant

leakage. If this is evident replace the outer

diaphragm.

The outer diaphragm is resistant to coolant

and oils. However if the outer diaphragm is

damaged, the inner diaphragm could become

weakened with prolonged immersion in certain

coolants and oils.

The user must not remove the inner

diaphragm. If damaged, return the probe

to your supplier for repair.

OUTER DIAPHRAGM INSPECTION

  1. Remove the stylus

  2. Unscrew the front cover.

  3. Inspect outer diaphragm for damage.

  4. To remove outer diaphragm, grip near the

middle and pull upwards.

INNER DIAPHRAGM INSPECTION

  5. Inspect inner diaphragm for damage.

If damaged return the probe to your

supplier for repair.

DO NOT REMOVE INNER DIAPHRAGM

OUTER DIAPHRAGM REPLACEMENT

  6. Screw tool fully into stylus holder.

  7. Fit new diaphragm.

  8. The diaphragm must locate centrally in

the stylus holder groove.

  9. Press diaphragm to expel trapped air.

10. Remove tool.

11. Lightly smear medium grease on front

cover lower surface. Then refit cover

and tighten.

12. Refit stylus
