Introduction
Important
Read, understand and obey the safety rules and
operating instructions in the Genie Z-30/20N
Operator's Manual or the Z-34/22 and Z-34/22N
Operator's Manual before attempting any
maintenance or repair procedure.
This manual provides detailed scheduled
maintenance information for the machine owner
and user. It also provides troubleshooting fault
codes 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.
Compliance
Machine Classification
Group B/Type 3 as defined by ISO 16368
Machine Design Life
Unrestricted with proper operation, inspection and
scheduled maintenance.
Technical Publications
Genie has endeavored to deliver the highest degree
of accuracy possible. However, continuous
improvement of our products is a Genie policy.
Therefore, product specifications are subject to
change without notice.

SAFETY RULES
vi
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 an 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
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.

Viscosity index 200
Cleanliness level, minimum 15/13
Water content, maximum 200 ppm
Chevron Rando HD oil is fully compatible and
mixable with Shell Donax TG (Dexron III) oils.
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, corrosion inhibition, seal conditioning, and
foam and aeration suppression properties.

Fire resistant UCON Hydrolube HP-5046
Quintolubric 822
Mineral based Shell Tellus T32
Shell Tellus T46
Chevron Aviation A
Continued use of Chevron
Aviation A hydraulic fluid when
ambient temperatures are
consistently above 32°F / 0°C may
result in component damage.
Note: Use Chevron Aviation A hydraulic fluid when
ambient temperatures are consistently below
0°F / -18°C.
Note: Use Shell Tellus T46 hydraulic oil when oil
temperatures consistently exceed 205°F / 96°C.
Note: Genie specifications require additional
equipment and special installation instructions for
the approved optional fluids. Consult the Genie

Hydraulic Hose and Fitting
Torque Specifications
Your machine is equipped with Parker Seal-Lok®
fittings and hose ends. Genie specifications require
that fittings and hose ends be torqued to
specification when they are removed and installed
or when new hoses or fittings are installed.
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-rings used in the Parker Seal Lok®
fittings and hose ends are custom-size O-rings.
They are not standard SAE 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 that the face seal O-ring 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 per given size as shown in the table.
6 Operate all machine functions and inspect the
hoses and fittings and related components to
confirm that there are no leaks.
