Important
Read, understand and obey the safety rules and
operating instructions in the appropriate Operator's
Manual on your machine before attempting any
procedure.
This manual provides troubleshooting and repair
procedures for qualified service professionals.
Basic mechanical, hydraulic and electrical skills are
required to perform most procedures. However,
several procedures require specialized skills, tools,
lifting equipment and a suitable workshop. In these
instances, we strongly recommend that
maintenance and repair be performed at an
authorized Genie dealer service center.

Danger
Failure to obey the instructions and safety rules in
this manual and the appropriate Operator's Manual
on your machine will result in death or serious
injury.
Many of the hazards identified in the operator's
manual are also safety hazards when maintenance
and repair procedures are performed.
Do Not Perform Maintenance
Unless:
You are trained and qualified to perform
maintenance on this machine.
You read, understand and obey:
•manufacturer's instructions and safety rules
•employer's safety rules and worksite
regulations
•applicable governmental regulations
You have the appropriate tools, lifting
equipment and a suitable workshop.

Safety Rules
vi Z®-30/20N • Z®-30/20N RJ • Z®-34/22 • Z®-34/22N Part No. 1268498GT
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 main
tained 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.

specifications require hydraulic oils which are
designed to give maximum protection to hydraulic

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.

Valve Coil Resistance
Note: The following coil resistance specifications are at
an ambient temperature of 68°F / 20°C. As valve coil
resistance is sensitive to changes in air temperature, the
coil resistance will typically increase or decrease by 4%
for each 18°F / 10°C that your air temperature increases
or decreases from 68°F / 20°C.
