Safety Rules
vi Z®-45/25 Bi-Energy • Z®-45/25J Bi-Energy Part No. 1268546GT
Personal Safety
Any person working on or around a machine must
be aware of all known safety hazards. Personal
safety and the continued safe operation of the
machine should be your top priority.
Read each procedure thoroughly. This
manual and the decals on the machine,
use signal words to identify the following:
Safety alert symbol
—
used to alert
personnel to potential personal
injury hazards. Obey all safety
messages that follow this symbol
to avoid possible injury or death.
Indicates a imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
Indicates a potentially hazardous
situation which, if not avoided,
could result in death or
serious
injury.
Indicates a potentially hazardous
situation which, if not avoided,
may cause minor or moderate
injury.
Indicates a potentially hazardous
situation which, if not avoided,
may result in property damage.
Be sure to wear protective eye
wear and
other protective clothing if the situation
warrants it.
Be aware of potential crushing hazards
such as moving parts, free swinging or
unsecured components when lifting or
placing loads. Always wear approved
steel
-toed shoes.
Workplace Safety
Any person working on or around a machine must
be aware of all known safety hazards. Personal
safety and the continued safe operation of the
machine should be your top priority.
Be sure to keep sparks, flames and
lighted tobacco away from flammable and
combustible materials like battery gases
and engine fuels. Always have an
approved fire extinguisher within easy
reach.
Be sure that all tools and working areas
are properly maintained and ready for
use. Keep work surfaces clean and free
of
debris that could get into machine
components and cause damage.
Be sure any forklift, overhead crane or
other lifting or supporting device is fully
capable of supporting and stabilizing the
weight to be lifted. Use only chains or
straps that are in
good condition and of
ample capacity.
Be sure that fasteners intended for one
time use (i.e., cotter pins and self
-locking
nuts) are not reused. These components
may fail if they are used a second time.
Be sure to properly dispose of old oil or
other fluids. Use an approved container.
Please be environmentally safe.
Be sure that your workshop or work area
is properly ventilated and well lit.

Hydraulic Oil Specifications
Hydraulic Fluid Specifications
Genie specifications require hydraulic oils which are
designed to give maximum protection to hydraulic
systems, have the ability to perform over a wide
temperature range, and the viscosity index should
exceed 140. They should provide excellent antiwear,
oxidation prevention, corrosion inhibition, seal
conditioning, and foam and aeration suppression
properties.

Note: Genie specifications require additional
equipment and special installation instructions for
the approved optional fluids. Consult Genie
Product Support before use.
Optional fluids may not have
the same hydraulic lifespan and
may result in component
damage.
Note: Extended machine operation can cause the
hydraulic fluid temperature to increase beyond it's
maximum allowable range. If the hydraulic fluid
temperature consistently exceeds 200°F / 90°C an
optional oil cooler may be required.
Do not top off with incompatible
hydraulic fluids. Hydraulic fluids
may be incompatible due to the
differences in base additive
chemistry. When
incompatible
fluids are mixed, insoluble
materials may form and deposit
in the hydraulic system,
plugging hydraulic lines, filters,
control valves and may result in
component damage.
Note: Do not operate the machine when the
ambient air temperature is consistently above
120°F / 49°C.

Torque Procedure
Seal-Lok™ fittings
1 Replace the O-ring. The O-ring must be
replaced anytime the seal has been broken.
The O-ring cannot be re-used if the fitting or
hose end has been tightened beyond finger
tight.
Note: The O-ring in Parker Seal Lok™ fittings and
hose end are custom-size O-rings. They are not
standard size O-rings. They are available in the
O-ring field service kit (Genie part number 49612).
2 Lubricate the O-ring before installation.
3 Be sure the O-ring face seal is seated and
retained properly.
4 Position the tube and nut squarely on the face
seal end of the fitting, and tighten the nut
finger tight.
5 Tighten the nut or fitting to the appropriate
torque. Refer to the appropriate torque chart in
this section.
6 Operate all machine functions and inspect the
hose, fittings and related components to
confirm there are no leaks.
JIC 37° fittings
1 Align the tube flare (hex nut) against the nose
of the fitting body (body hex fitting) and tighten
the hex nut to the body hex fitting to hand tight,
approximately 30 in-lbs / 3.4 Nm.
2 Using a permanent ink marker, make a
reference mark on one the flats of the hex nut
and continue the mark onto the body of the
hex fitting. Refer to Illustration 1.

3 Working clockwise on the body hex fitting,
make a second mark with a permanent ink
marker to indicate the proper tightening
position. Refer to Illustration 2.
Note: Use the JIC 37° Fitting table in this section to
determine the correct number of flats, for the
proper tightening position.
Note: The marks indicate the correct tightening
positions have been determined. Use the second
mark on the body hex fitting to properly tighten the
joint after it has been loosened.

4 Tighten the hex nut until the mark on the hex
nut is aligned with the second mark on the
body hex fitting.
5 Operate all machine functions and inspect the
hose, fittings and related components to
confirm there are no leaks.
