CLEANING AND INSPECTION

WARNING

Skysol-100 mixture is combustible. Use mechanical ventilation whenever

product is used in a confined space, is heated above ambient

temperatures, or is agitated. DO NOT use or store near heat, sparks,

flame, or other ignition sources. 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 fifteen (15) minutes or until irritation subsides. Inhalation

may cause irritation to upper respiratory passages. DO NOT have food or

drink in the vicinity.

Clean flange of crankshaft (4) and seal surface of crankshaft pulley (1) with Skysol-100 and dry

with lint-free cloth.

Inspect seal surface of crankshaft pulley (1) for cracks, breaks, and gouges. Replace crankshaft

pulley (1) if cracked, broken, or gouged.
