Break stem
1. Remove the stylus and holder (see page 17).
2. Remove the break stem using the 5 mm A/F
spanner.
3. Use a C spanner to remove the probe’s front
cover. This will expose the metal eyelid seal
and the inner diaphragm seal. Remove the
metal eyelid and spring.
CAUTION: These may fall out.
4. Wash inside the probe, using clean coolant.
CAUTION: Do not use sharp metal objects to
clean out debris.
5. Inspect the diaphragm seal for signs of
piercing or damage. In the event of damage,
return the probe to your supplier for repair, as
coolant entering the probe mechanism could
cause the probe to fail.
6. Refit the spring and metal eyelid (the spring’s
widest diameter is against the metal eyelid).
7. Refit the remaining components (see
pages 16 and 17).
