Safety Rules
vi Z®-34/22 Bi-Energy Part No. 1268515GT
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 fo
llow 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 prote
ctive 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 aerat
ion suppression

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 its
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
