CLEANING AND INSPECTION

WARNING

Skysol 100 solvent is combustible; DO NOT use or store near

heat, sparks, flame, or other ignition sources. Use mechanical

ventilation whenever product is used in a confined space,

heated above ambient temperatures, or agitated. Keep

container sealed when not in use.

Contact with Skysol 100 may cause skin irritation. Use

chemical-resistant gloves. In case of skin contact, remove any

contaminated clothing and wash skin thoroughly with soap

and water. Wash contaminated clothing before reuse. Eye

contact may cause irritation, tearing, or blurring of vision. Use

face shield or goggles when eye contact may occur. In case of

eye contact, flush eyes with large amounts of water for at

least 15 minutes or until irritation subsides. Inhalation may

cause irritation to upper respiratory passages. DO NOT have

food or drink in the vicinity. Failure to comply may result in

injury to personnel.

Compressed air source must not exceed 30 psi (207 kPa).

When cleaning with compressed air, eyeshields must be worn.

Failure to wear eyeshields may result in injury to personnel.

with wire brush, wipe clean with Skysol 100 solvent, and dry with compressed air. Replace burner (4) if

insulating pad is charred or parts are missing.
