WARNING

TRICHLOROTRIFLUOROETHANE

Fumes of TRICHLOROTRIFLUOROETHANE are poisonous. Provide adequate ventilation

whenever you use TRICHLOROTRIFLUOROETHANE. Do not use solvent near heat or open

flame. TRICHLOROTRIFLUOROETHANE will not burn, but heat changes the gas into

poisonous, irritating fumes. DO NOT breathe the fumes or vapors. TRICHLOROTRl-

FLUOROETHANE dissolves natural skin oils. DO NOT get the solvent on your skin. Use

gloves, sleeves and an apron which the solvent cannot penetrate. If the solvent is taken

internally, consult a physician immediately.

1. Inspect exterior of test set. It should be free of dust, dirt, grease, and fungus.

2. Remove dust and loose dirt with a clean, soft cloth.

3. Use a cloth dampened (not wet) with TRICHLOROTRIFLUOROETHANE to remove grease,

fungus, and ground-in dirt.

4. Remove dust or dirt from power cable assembly and connectors with a soft brush. Remove

grease or grime with a lint-free cloth moistened with TRICHLOROTRIFLUOROETHANE.
