8.4.4 Lubricating the Turntable's Telescopic Tube
This task is restricted to the maintenance personnel .
The crank-driven telescopic tube for DUT height adjustment in the chamber's azimuth
turntable system requires regular lubrication.
●
If you notice that the crank drive does not operate smoothly, apply lubricant imme-
diately instead of weekly.
●
If you use the height adjustment infrequently, lubrication on a monthly basis can be
sufficient.
We recommend using a synthetic PTFE (polytetrafluoroethylene, Teflon) ceramic oil
spray or a bonding dry film lubricant. You can use, for example,
Lube TF from Interflon
or similar. The PTFE ceramic oil spray Teflux from Normfest is also ideally suited. How-
ever, it is not included in the delivery due to restrictions regarding air transport.
To apply ceramic oil spray to the telescopic tube
1. Open the door; see Chapter 7.3.3, "Opening the Door" , on page 46.
2. Deactivate the chamber as described in Chapter 7.2, "Deactivating the Chamber" ,
on page 43.
3. Release the clamping screw; see "To move the DUT to a higher or lower position"
on page 47.
4. Insert the turntable's crank ( Figure 7-3 ) into the hexagonal socket (labeled 3 in Fig-
ure 7-2 ).
5. Move the telescopic tube to its highest position.
To do so, turn the crank.
6. Hold a sheet of paper behind the telescopic tube.
The paper can catch oil spray that misses the tube.
7. Hold the spray bottle as recommended in its instructions for use.
8. Direct its nozzle toward the middle part of the telescopic tube.
9. Apply one short squirt of oil spray from one side.
10. Repeat this procedure from the opposite side of the telescopic tube.
11. Optionally, activate the chamber as described in Chapter 7.1, "Activating the
Chamber" , on page 43.
