7.2.3 Lubricating the bearing points and
the nut of the micrometer spindle
Under normal operating conditions it is sufficient
to lubricate the bearing points and the nut of the
micrometer spindle after approx. every 250 hours
of service:
• Switch the instrument on (MAN mode - see
chapter 5.4.3).
• Remove specimen holder and base plate from
the sledge.
• Remove cover (3):
the first lubrication point (1) becomes visible.
• Fill the grease gun (standard delivery) and ex-
tract the air from the gun (press several times
on a cleaning cloth or piece of paper until
grease comes out).
• Place the grease gun onto the first lubrication
point and press once or twice.
• Via the manual sledge movement (area 5.2,
chapter 5.4.14) move the sledge backwards
until the second lubrication point (2) becomes
visible through the round opening in the cover
ribbon.
• Place the grease gun onto the second lubri-
cation point and press once or twice.
• If required, move the sledge back forward as
far as needed (manual sledge movement, area
5.2, chapter 5.4.14).
• Put cover (3) back in place.
• Re-insert the base plate and specimen holder
(see chapter 5.5.1).
