Repair or replace unserviceable parts and hardware. Always replace packings,
gaskets, seals, lockwashers, locknuts, locking wire, rivets and cotter pins with
new parts.
C Remove burrs with a stone or file. Remove burrs on closely fitted mating
surfaces by lapping the surfaces with abrasive-grade compound.

WARNING
Dry-cleaning solvent (PD-680)is toxic and flammable.
To prevent personal injury when using PD-680, use
only in a well ventilated area. Avoid breathing vapors.
If you become dizzy get fresh air immediately and seek
medical attention. Avoid contact with eyes, skin and
clothing. Use protective goggles, gloves, and clothing.
If contact is made, immediately flush with water and
seek medical attention. The flashpoint for Type I dry-
cleaning solvent is 100° F (38° C); for Type II it is 140°
F (60° C). Do not use near open flame or excessive
heat.
Clean metal parts with dry-cleaning solvent (item 20, Appx D). Metal or
fiber brushes may be used to apply cleaning solvent and to remove
softened or dissolved material. Hand scraping with metal scrapers maybe
used to remove soft coatings or deposits.
Soak very oily or greasy metal parts in a tank containing dry-cleaning
solvent (item 20, Appx D). The soaking time in solvent varies with type
and amount of material to be removed.
