while using 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.
Compressed air, used for cleaning purposes will not exceed 30 psi. Use only with effective chip guarding
and personnel protective equipment (goggles/shield/gloves, etc.).

problem. Clean as you work and as needed. Use dry cleaning solvent (P-D-680) to clean metal surfaces.
Use soap and water when you clean rubber or plastic material.
Bolts, nuts and screws: check that they are not loose, missing, bent, or broken. You can't try
them all with a tool, of course, but look for chipped paint, bare metal or rust around bolt heads. Tighten
any bolt, nut, or screw that you find loose.
Welds: look for loose or chipped paint, rust or gaps where parts are welded together. If you find
a bad weld, report it to intermediate direct support.
Electric wires and connectors: look for cracked or broken insulation, bare wires and loose or
broken connectors. Tighten loose connections and make sure the wires are in good condition.
Hoses an fluid lines: look for wear, damage and leaks. make sure clamps and fittings are tight.
Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If leakage comes
from a loose fitting or connector, tighten the fitting or connector. If something is broken or worn out,
either correct it or report it to intermediate direct support (refer to the Maintenance Allocation Chart).
The cooling system is pressurized. Personal injury may result when removing the radiator cap after
