MAINTENANCE OF THE CONTROL PANEL ASSEMBLY
The control panel assembly houses the necessary
instruments and controls needed for the operation
of the generator set. They include the voltage regu-
lator, terminal board assembly, rectifiers, volt-
meter, load switch, rheostat, duplex receptacle, ter-
minal load, percent load meter (DOD model MEP-
024A only), radio interference suppression com-
ponents, and wiring. All components are accessible
by raising the hinged panel.

Clean all parts in a well-ventilated
area. Avoid inhalation of solvent
fumes and prolonged exposure of skin
to cleaning solvent. Wash exposed
skin thoroughly. Dry cleaning solvent
(Fed. Spec.- P-D-680) used tO clean
parts is potentially dangerous to per-
sonnel and property. Do not use near
open flame or excessive heat. Flash
point of solvent is 100° to 138°F. (38° to
