20. Maintenance Responsibility

Organizational maintenance, or routine preventive care and adjustment, of the electronic organ will be performed by the organist or the using organization. Other maintenance should be referred through proper channels.


b. IN OVERSEA AREAS. Maintenance of the electronic organ in oversea installations will be accomplished as directed by appropriate commanders.

21. General Operative Care

It is the responsibility of every organist to keep the instrument he uses in the best possible condition. This entails frequent inspection, followed when necessary by reports of defective or unserviceable items. Reports should be made through channels, as indicated in paragraph 20. Equipment also must be protected against avoidable damage by keeping it clean and well lubricated.

22. Cleaning

a. GENERAL. Clean all wooden parts and playing keys with clean lint-free cloth (cheesecloth).

b. KEY CONTACTS. If a key has become silent as a result of dust accumulation on the key contacts: strike it 15 or 20 times in a rapid staccato manner. If this does not dislodge dust particles and clear the contacts, report the difficulty through the proper channels.

c. PEDAL CLAVIER. To clean the pedal clavier, remove it from its position in front of the console. Proceed in the following manner:

23. Lubricating

a. APPROVED LUBRICANTS. Lubricating materials required for servicing the electronic organ, AN/TNP-1 (see SB 38-5-3), consist of the following:

Lubricant symbol Standard nomenclature
RL* Oil, recoil, light.
PL Oil, lubricating preservative, special.

*Lubricant RL will ignite at 175° F. For this reason observe proper precautions to avoid overheating when handling or storing.

b. CONSOLE. By flowing along numerous fabric wicks, oil is supplied to the motors as well as other moving organ parts from centralized troughs. Oil troughs are supplied from four oil cups. The location of these oil cups is given on the oiling instruction plate (see fig. 3). Lubricate the console every 90 days in the following manner:

c. REVERBERATION ATTACHMENT. The reverberation attachment (see par. 5) consists of a spring assembly with springs enclosed within oil tubes (see fig. 6). Oil tubes must be inspected periodically and, when necessary, lubricated as follows:

(1) Use screw driver to remove right-hand screws from the reverberation attachment protective cover. Swing the cover outward on its hinges.

(2) Use lubricant RL to fill the three long brass oil tubes to a point 1 inch from the top.

(3) Use lubricant RL to flIt the short oil tube as follows:
