Drycleaning solvent is flammable and toxic. Do not use near
open flame and always have a fire extinguisher nearby when
solvents are used. Use only in well-ventilated places, wear
protective clothing, and dispose of cleaning rags in approved
container. Failure to do this may result in injury to personnel
and damage to equipment.
Eyeshields must be worn when cleaning with compressed air.
Compressed air source will not exceed 30 psi (207 kPa). Failure
to do so may result in injury to personnel.
