SECTION V
PERIODIC INSPECTION, MAINTENANCE, AND LUBRICATION
5-1.
GENERAL -
No periodic inspection, maintenance, or lubrication is required for cable Tensiometers.
As a matter of general practice, the instrument should be kept clean at all times. Particular attention
should be paid to the two sectors and the riser block to see that they are always free from foreign
matter. The instrument as shipped by the manufacturer has been lubricated. In the event that repairs
are made as outlined in Section VI, lubrication should be accomplished as listed in table 3. Method of
application is a light wipe.
*Explanation: D. C. #33: Dow Corning Grease #33 fluid type or equivalent to NATO G-395 fluid type per MIL-
PRF-81322.

SECTION VI
TROUBLE SHOOTING
6-1.
GENERAL
-
The instrument will be free from trouble such as would be caused by nominal use. The
instrument, however, can be damaged by mistreatment and improper usage. If a detail part of the
instrument becomes damaged or broken, disassemble the instrument in the order of the index
numbers indicated on the exploded view, Figure 6. All detail parts of the instrument are so integrated
that in order to perform a disassembly operation it is necessary that disassembly be started with index
number 1 and continued in numerical sequence. The only exception to this is the latch mechanism (37
through 40, Figure 6). Reassembly is the opposite of disassembly. Whenever the instrument has been
disassembled, it must be recalibrated. (See Section VII.)
