NOTE: Aside from JLG recommendations, it is not advisable to
mix oils of different brands or types, as they may not con-
tain the same required additives or be of comparable vis-
cosities. If use of hydraulic oil other than Mobil DTE 11M
is desired, contact JLG Industries for proper recommen-
dations.
NOTE: Machines Manufactured before S/N 03000046376 were
filled with Mobilfluid 424 hydraulic oil. If desired to
change to Mobil DTE 11M hydraulic oil, the telescope
seals are recommended to be changed. These are
included in (JLG) kit P/N 8457399. Also included in the
kit, is a decal to be located on the hydraulic tank to iden-
tify Mobil DTE 11M oil in use.
