+0° F to +180° F (-18° C to -83° C)
+0° F to +210° F (-18° C to +99° C)
+50° F to +210° F (+10° C to +99° C)
NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stabil-
ity for mobile hydraulic system service.
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.
The hydraulic oil level in the pump reservoir can vary with oil
temperature (i.e., the oil level in a cold machine may not be up
to the FULL line on the dipstick). Cycle the mast up and down
a few times to get a more accurate reading on the dipstick.
Once the hydraulic oil is warmed, check the dipstick reading.
