USING SOLVENTS FOR CLEANING:

A solvent is generally required when dirt contains oil or grease. Only petroleum distillates should be used to clean electrical components. Recommended are safety type petroleum solvents having a flash point greater than 100° F. (38° C.).

Use a soft brush or cloth to apply the solvent. Use care to avoid damaging magnet wire or winding insu- lation. After cleaning, dry all components thoroughly with moisture-free, low pressure compressed air.

DANGER! DO NOT WORK WITH SOLVENTS

!IN ANY ENCLOSED AREA. ALWAYS PRO- VIDE ADEQUATE VENTILATION. FIRE, EXPLOSION OR OTHER HEALTH HAZARDS MAY EXIST UNLESS ADEQUATE VENTILA- TION IS PROVIDED. WEAR EYE PROTEC- TION. WEAR RUBBER GLOVES TO PROTECT THE HANDS.

CAUTION! Some generators use epoxy or

!polyester base winding varnishes. Use sol- vents that do not at tack such materials.

DRYING THE GENERATOR

GENERAL:

If testing indicates that the insulation resistance of a winding Is below a safe value, the winding should be dried before operating the unit Some recommended drying methods include (a) heating units and (b) forced air.

HEATING UNITS:

If drying is needed, the generator can be enclosed in a covering. Heating units can then be installed to raise the temperature about 15°-18° F. (8°-10° C.) above ambient.

FORCED AIR:

Portable forced air heaters can be used to dry the generator. Direct the heated air into the generator's air intake openings. Run the unit at no-load. Air tem- perature at the point of entry into the generator should not exceed 150° F. (66° C.).
