SECTION 2 - GENERAL SERVICE INFORMATION
vent arcing inside the swing bearing, the lifting chains or
the cylinders.

Lubrication

Components and assemblies requiring lubrication and
servicing are shown in Section 1.7. Service applicable
components with the amount, type, and grade of lubricant
are recommended in this manual, at the specified inter-
vals. When recommended lubricants are not available,
consult your local supplier for an equivalent that meets or
exceeds the specifications listed.

Battery

Clean and dry battery top. Ensure all connections are
clean and correctly tight. Coat terminals with a silicone
dielectric compound.
Drain the water that can accumulate at the bottom of the
batteries container. (Refer to Section 8-2).

2.4 LUBRICATION INFORMATION

Hydraulic System

The primary enemy of a hydraulic system is contamina-
tion. Contaminants enter the system by various means,
e.g., using inadequate hydraulic oil, allowing moisture,
grease, filings, sealing components, sand, etc., to enter
when performing maintenance, or by permitting the pump
to cavitate due to insufficient system warm-up or leaks in
the pump supply.
The design and manufacturing tolerances of the compo-
nent working parts are very close, therefore, even the
smallest amount of dirt or foreign matter entering a system
can cause wear or damage to the components and gener-
ally results in faulty operation. Every precaution must be
taken to keep hydraulic oil clean, including reserve oil in
storage.
Replace hydraulic filter at recommended intervals.
Cloudy oils indicate a high moisture content which per-
mits organic growth, resulting in oxidation or corrosion. If
this condition occurs, the system must be drained,
flushed, and refilled with clean oil.
It is not advisable to mix oils of different brands or types,
as they may not contain the same required additives or be
of comparable viscosities. Good grade mineral oils, with
viscosities suited to the ambient temperatures in which
the machine is operating, are recommended for use.
NOTE: Metal particles may appear in the oil of new
machines due to the wear-in of meshing compo-
nents.

Lubrication Specifications

Specified lubricants, as recommended by the component
manufacturers, are always the best choice, however,
multi-purpose greases usually have the qualities which
meet a variety of single purpose grease requirements.

Should any question arise regarding the use of greases in
maintenance stock, consult your local supplier for evalua-
tion. Refer to Section 1.7 of this Service Manual for an
explanation of the lubricant key designations appearing in
the Lubrication Chart.

Hydraulic Oil

For best performance, JLG recommends the use of ISO
VG 32 oil with a viscosity of 32 cSt at 40 °C. Refer to Sec-
tion 1.7 of this Service Manual for recommended hydraulic
oils.

Changing Hydraulic Oil

Use of any of the recommended hydraulic oils eliminates
the need for changing the oil on a regular basis. If it is nec-
essary to change the oil, use only those oils meeting or
exceeding the specifications appearing in this manual. If
unable to obtain the same type of oil supplied with the
machine, consult local supplier for assistance in selecting
the proper equivalent. Avoid mixing petroleum and syn-
thetic base oils. JLG Industries recommends changing the
hydraulic oil at least every 2 years.
Use every precaution to keep the hydraulic oil clean. If the
oil must be poured from the original container into
another, be sure to clean all possible contaminants from
the service container.
While the unit is shut down, a good preventive mainte-
nance measure is to make a thorough inspection of all
hydraulic components, lines, fittings, etc., as well as a
functional check of each system, before placing the
machine back in service.

2.5 PRESSURE RELIEF VALUES

Pressure relieving in the hydraulic circuit is achieved by a
proportional electric relief valve installed on the power unit
valve body. The valve is adjusted by an electric input.
Pressure relief values of machine functions can be
checked by connecting a pressure gauge at port "2" on
the hydraulic power unit valve body.
Before checking pressure relief values, operate the
machine a few minutes to warm the hydraulic oil.
For a correct reading of pressure relief values, the
machine must be operated from the platform console at
maximum speed (max. travel of the joysticks). Read the
pressure values when the cylinders are at end of stroke or
when the structure is fully swung either to the left or to the
right. When checking pressure relief value of the swing
function, the mast must be fully lowered.
In case of noisy operation of the pressure relief valve
when cylinders are at end of stroke, bleed the air from the
valve.
Refer to Sections 7 and 9-8 of this manual for further infor-
mation.
