CLEANING AND INSPECTION
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.

Inspect cover (1) for cracks, breaks, and gouges. Replace cover (1) if cracked, broken, or gouged.
Tighten locator screws only finger-tight so that when seal and seal sleeve
are installed they will self-align.
Install locator on rear of crankshaft (4) with two locator screws.
Rear crankshaft seal must be installed with wear sleeve in place. Do not
remove wear sleeve from rear crankshaft seal. Failure to comply may result
in damage to equipment.
Position new rear seal (2) on seal sleeve with beveled edge of wear sleeve (3) facing toward locator.
Install rear seal (2) and seal sleeve as a unit over locator and tighten two locator screws.
Position seal installer over locator, seal sleeve, and rear seal (2) and finger-tighten nut assembly.
