43. Painting
Painted surfaces that show scratches and abrasions should be cleaned and repainted. Inspect all painted surfaces for
chipping, peeling, and wrinkling. Sandpaper the damaged paint areas and repaint. Before applying paint, mask the
identification plates, machined surfaces, wires and other electrical parts, breather cap, vents, and lubrication fittings. In
general, apply paint to surfaces that have been painted and to no other. Refer to TM 9-2851 for specific painting
instructions.
Section III. PREVENTIVE MAINTENANCE SERVICES
44. General
The operator of the truck mounted air compressor and the organizational maintenance personnel must perform their
preventive maintenance services regularly, to make sure the air compressor operates well and to lessen the chances of
mechanical failure.
45. Operator Maintenance
a. Inspections. Inspections must be made before operation, during operation, at halt, and after operation, as
described in this section. All inspections of assemblies, subassemblies, or parts must include any supporting members or
connections and must determine whether the unit is in good condition, correctly assembled, secure, or excessively worn.
Any mechanical condition which may result in further damage to the unit must be corrected before the equipment is
operated.
(1) The inspection for "good condition" is usually an external visual inspection to determine whether the unit is
damaged beyond safe or serviceable limits, or to determine if it is in such a condition that damage will result from
operation. The term "good condition" is further defined as: not bent or twisted; not chaffed or burned; not broken or
cracked; not bare or frayed; not dented or collapsed; not torn or cut; adequately lubricated.
(2) Inspection of a unit to see that it is "correctly assembled" is usually an external visual inspection to
determine whether it is in its normal assembled position in the equipment.
(3) Check of the unit to determine if it is "secure" is usually an external inspection, a hand-feel, or a pry-bar or
wrench check for looseness in the units. Such an inspection should include brackets, lockwashers, locknuts, locking
wires, or cotter pins used in the assembly.
