1.4 TORQUE REQUIREMENTS

When maintenance becomes necessary or a fastener has
loosened, refer to the applicable Torque Chart (Figure 1-
4., Figure 1-5. and
Figure 1-6.) in this section of the man-
ual to determine proper torque values for various size fas-
teners.

1.5 LUBRICATION

Hydraulic Oil

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. JLG Industries,
recommends Mobilfluid 424 hydraulic oil, which has an
SAE viscosity of 10W-30 and a viscosity index of 152.

For cold weather applications, i.e. when temperatures
remain consistently below +20°F (–7°C) JLG recom-
mends using Mobil DTE 13 hydraulic oil.

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 Mobilfluid 424 is
desired, contact JLG Industries for proper recommenda-
tions.

1.6 HYDRAULIC PRESSURE SETTINGS AND

ADJUSTMENT

Adjust system pressure so that platform will raise with
maximum rated capacity in platform.

Perform pressure adjustment with oil at normal operating
temperature. If pressure is set when oil is cold, platform
may not raise rated load after oil has warmed.

The following pressure setting is the factory recom-
mended (initial) setting;

Turning adjustment screw clockwise increases system
pressure
, turning screw counterclockwise decreases
system pressure
