Cleaning solvent is flammable and its vapor is potentially explosive. Do not use clean-
ing solvent in the vicinity of spark, open flame, or excessive heat. Do not use cleaning
solvent in unventilated spaces. Failure to comply can result in serious injury or death.
Do not allow hydraulic fluid or cleaning solvent to come in contact with unprotected
skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can cause
serious injury. Always wear chemical protective gloves and goggles when handling
used hydraulic fluid and cleaning solvent. Failure to comply can result in illness, seri-
ous injury, or death.
