WARNING
Dry cleaning solvent P-D-680 is toxic and flammable. Wear protective goggles
and gloves and use in a well-ventilated area. Avoid contact with skin, eyes, and
clothes. Do not breathe vapors. Do not use near open frame or excessive heat.
The flash point is 100-138°F (38-50°C). If you become dizzy while using cleaning
solvent, get fresh air immediately and seek medical aid. If contact with eyes is
made, wash with water and get medical aid immediately.
Use goggles, rubber gloves, and rubber apron when cleaning parts in carbon
removing compound. Provide adequate ventilation. Avoid inhaling fumes and
contact with skin. If compound is splashed on skin, flush with water and wash
with alcohol. Alcohol containing 2 or 3 percent camphor is preferable. If contact
with eyes is made, flush eyes with water and get medical aid immediately.
Compressed air used for cleaning purposes will not exceed 30 PSI. Use only
with effective chip guarding and personal protective equipment (goggles/shield,
gloves, etc.)
CAUTIO N
Do not use wire brush on lower section of piston with tin plating. Wire brush will remove
tin plating and damage piston. Wire brush only upper section with four top grooves to
remove any hard carbon.
Clean piston components with cleaning solvent and dry with compressed air. If cleaning solvent
does not remove carbon deposits, use carbon removing compound which will not harm
bushings or tin plating on piston.
Clean ring grooves with piston ring groove cleaner or broken compression ring ground to a
beveled edge.
Clean inside surfaces of piston and oil drain holes in lower part of piston. Do not enlarge holes
during cleaning.
