Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
WARNING Always use protective eyewear when using compressed air or nitrogen.
Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces. Clean air cannot
damage a device or leave particles or residues behind.
You can use any source of clean, dry, low-pressure compressed air or nitrogen that has an effective
oil-vapor filter and liquid condensation trap placed just before the outlet hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air pressure to less than 414 kPa
(60 psi) to control the velocity of the air stream. High-velocity streams of compressed air can cause
electrostatic effects when directed into a device. These electrostatic effects can damage the device.
Refer to “Electrostatic Discharge” earlier in this chapter for additional information.
WARNING Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed
container. It is extremely flammable. In case of fire, use alcohol foam, dry chemical, or
carbon dioxide; water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact with eyes, skin, and
clothing. It causes skin irritation, may cause eye damage, and is harmful if swallowed or
inhaled. It may be harmful if absorbed through the skin. Wash thoroughly after handling.
In case of spill, soak up with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable federal, state, and local
environmental regulations.
2. Clean the Mating Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the mating plane surfaces.
c. Let the alcohol evaporate, then blow the mating plane surface dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry a device before you reassemble or
use it.
3. Inspect
a. Inspect the mating plane surface to make sure that no particles or residue remain. “Visual
Inspection” on page 4-3 .
