WARNINGS

Before beginning any work on this equipment, review the general

safety precautions and procedures in TB 385-4, Safety Precautions

for Maintenance of Electrical and Electronic Equipment. Do not

work on equipment alone. Be sure that a person capable of ren-

dering first aid is present.

To prevent personal injury when applying or removing steel strapping

on crates or cartons, wear heavy gloves and protective eye glasses.

Do not handle cartons by the steel straps.

Adequate ventilation should be provided while using

TRICHLOROTRIFLUOROETHANE. Prolonged breathing of vapor should be avoided.

The solvent should not be used near heat or open flame; the products of

decomposition are toxic and irritating. Since TRICHLOROTRIFLUOROETHANE

dissolves natural oils, prolonged contact with skin should be avoided.

When necessary, use gloves which the solvent cannot penetrate. If the

solvent is taken internally, consult a physician immediately.

Compressed air shall not be used for cleaning purposes except where

reduced to less than 29 pounds per square inch (psi) and then only

with effective chip guarding and personnel protective equipment. -

Do not use compressed air to dry parts when TRICHLOROTRIFLUOROETHANE

has been used. Compressed air is dangerous and can cause serious

bodily harm if protective means or methods are not observed to

prevent chip or particle (of whatever size) from being blown into

the eyes or unbroken skin of the operator other personnel.

Do not attempt to lift or move the heavy components of the AB-621(*)/G

or MK-2044/G without adequate personnel.
