Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and
clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when
using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees
C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may
result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and
medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts
eyes, immediately flush eyes with water and get immediate medical attention.
Clean all components and flush cylinder barrel using drycleaning solvent (P-D-680) only. Do not use
cleaning cloth as any foreign material would contaminate hydraulic system.
Inspect barrel bore for any scratches or corrosion. Replace barrel if rusted. Replace barrel and piston if
either component is scratched.
Inspect rod for bending. Replace if necessary.
Inspect rod for scratches or pitting. Remove minor scratches and pitting by using stone and lubrication
oil. Stone imperfection just enough to smooth raised part.
Inspect component threads for burrs and stripped threads. Replace or repair as necessary.
