Prior to performing the following functions all electrical power is to be removed from the system.

External power disconnected and a "MAINTENANCE IN PROGRESS" tag attached or power

WARNING

Lifting heavy equipment incorrectly can cause serious injury. Do not try to lift more than 35

pounds by yourself. Get a helper. Bend legs while lifting. Don't support heavy weight with your

back.

WARNING

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

f l a m e , t h e p r o d u c t s o f d e c o m p o s i t i o n a r e t o x i c a n d i r r i t a t i n g . 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.

Compressed air shall not be used for cleaning purposes except where reduced to less than 29 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 un-

broken skin of the operator or other personnel.
