GENERAL REPAIR PRACTICES.
Replacement of Parts. Only replace unserviceable parts or parts which must be discarded. Always discard
the following: cotter pins, lockwire, lockwashers, locknuts, preformed packings, rubber seals and gaskets.
Cleaning. Cleaning is a necessary part of most tasks. Use the following guidelines when cleaning:
Dry cleaning solvent P-D-680 is toxic and flammable. Wear protective goggles and gloves and use
in a well ventilated area. Avoid contact with skin, eyes, and clothes and do not breathe vapors.
Do not use near open flame or excessive heat. The flash point is +100 to 138°F (+38 to 50°C). If
you become dizzy while using the solvent, get fresh air immediately and get medical aid. If
contact with eyes is made, wash your eyes with water and get medical aid immediately.
Use dry cleaning solvent P-D-680 for cleaning metal parts only.
Use a mild detergent solution for cleaning rubber, plastic and nylon parts.
Isopropyl alcohol is flammable. Inhalation of vapors can cause dizziness and headache. Contact
with skin may cause irritation. Keep isopropyl alcohol away from open flame or any spark
(ignition source). Keep at least a B-C fire extinguisher within easy reach when working with
isopropyl alcohol. Post signs that read "NO SMOKING WITHIN 50 FEET" when working with
isopropyl alcohol. Ensure adequate ventilation. If vapors cause drowsiness, go to fresh air. If
liquid contacts skin or eyes, immediately flush affected areas thoroughly with water.
Use isopropyl alcohol for cleaning electrical connector pins, wire end leads, and switch contacts.
