WARNING
Accidental or intentional introduc-
tion of liquid contaminants into the
environment is in violation of state,
federal, and military regulations.
Refer to Lubrication Order (para.

age, use, and disposal of these liq-
uids. Failure to do so may result in

temperature, 175° F to 200° F (79° C
to 93° C), use HOT FULL mark and
add as necessary.
