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.
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.
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.
Red—used to indicate the
presence of an imminently
hazardous situation which, if not
avoided, will result in death or
serious injury.
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.
Orange—used to indicate the
presence of a potentially
hazardous situation which, if not
avoided, could result in death or
serious injury.
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.
Yellow with safety alert symbol—
used to indicate the presence of a
potentially hazardous situation
which, if not avoided, may cause
minor or moderate injury.
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.
Yellow without safety alert
symbol—used to indicate the
presence of a potentially
hazardous situation which, if not
avoided, may result in property
damage.
Be sure to properly dispose of old oil or
other fluids. Use an approved container.
Please be environmentally safe.

Theory of Operation
Power Source
Electrical System
The Genie Z-34/22 & Genie Z-34/22N are powered
by eight six-volt (315 AH) batteries, separated into
two groups of four. Each group of four batteries is
wired in series to produce 24V DC. The two battery
groups are then joined to produce 48V DC. The
drive system uses 48V DC and the control system
uses 24V DC.
Drive system
Hydraulic System
All machine functions are performed by the
hydraulic system. The hydraulic system is powered
by a single-section gear pump. When the pump is
activated, it supplies hydraulic fluid under pressure
to the function manifold, where the control valves
are located. To protect from over-pressurization of
the hydraulic system, the pump is provided with a
pressure relief valve, set at 3200 psi (221 bar).
Activating a machine function is accomplished by
actuating or moving a toggle switch and/or control
handle, which sends voltage to the appropriate
directional control valve. The directional valve
determines which direction the hydraulic fluid will
travel. The amount of hydraulic fluid volume is
determined by the proportional valve input voltage
from the boom function speed controller at the
platform controls. Each boom lift cylinder
incorporates a counterbalance valve to prevent
movement in the event of a hydraulic line failure.
Part No. 36540
All Z-34/22 and Z-34/22N machines utilize a DC
drive motor on each non-steer wheel. The two
motors are connected in series and are controlled
by a solid-state motor controller. The motor
controller regulates the amount of current applied
to the drive motors based upon the position of the
drive controller (joystick), which allows proportional
drive speed control.
Z-34/22 machines (before serial number 1734) and
Z-34/22N machines (before serial number 2227)
use series-wound DC drive motors and a solid
state motor controller designed for series motors. A
mechanical forward/reverse contactor provides
directional control of the drive motors. These
machines also have a proportional braking system,
which is active in the drive controller (joystick)
range between neutral position and half way to full
deflection in both drive directions. The drive
controller has a 0-5 V DC voltage output which
activates the motor controller, as well as a
proportional coil output for the brake system.
Z-34/22 machines (after serial number 1733) and
Z-34/22N machines (after serial number 2226) use
separately excited (Sepex) DC drive motors and a
Sepex motor controller. No forward/reverse
contactor is required in this system, as the
controller does the switching automatically. The
Sepex drive system utilizes regenerative braking,
which means that the drive motors are used to
slow down and stop the machine. The resulting
Genie Z-34/22 & Genie Z-34/22N
v

THEORY OF OPERATION
energy is then returned to the batteries.
Regenerative braking allows the use of a simple,
non-proportional parking brake which applies after
the machine has come to a stop, or if the
Emergency Stop button is pushed in to the OFF
position.
The Sepex motor controller also incorporates self
diagnostics. An LED on the motor controller will
flash a fault code when a fault is present to aid in
troubleshooting. Refer to the fault code chart in
Section Five.
Limit switches
There are two types of limit switches, which are
found in various locations on the machine: drive
speed limit switches and a drive enable limit
switch.
The function of a drive speed limit switch is to limit
the raised machine drive speed to 0.6 miles per
hour (1 km/h) when either the primary or
secondary boom is raised more than 2 feet (0.6 m)
OR when the primary boom is extended more than
12 inches (30 cm).
The function of the drive enable limit switch is to
limit the ability of the machine to drive when the
boom is rotated outside the area between the nonsteer wheels.
Machine Controls
The Z-34/22 and Z-34/22N machines are equipped
with operational controls which are found in two
locations: the ground controls, located opposite the
hydraulic tank side of the machine, and the
platform controls, located in the platform. All lift and
drive functions are available at the platform
controls. Only boom functions are available at the
ground controls. Moving a boom function toggle
switch in the direction indicated on the control
panel decal will determine which boom function will
operate and its direction of travel.
The platform controls incorporates a rotary boom
function speed controller which, by varying the
position of the controller, controls the amount of
voltage to the boom function proportional valve.
This controller determines the speed at which the
function will operate.
The drive controller (joystick) is fitted with a
potentiometer that communicates the drive
controller position with the motor controller. A
thumb rocker switch on the top of the drive
controller is used for steering.
Washing electronic components is not suggested.
Instead, use compressed air to remove debris.
Component damage hazard. Avoid
shock or impact to the motor
controller. Internal damage may
not be visible from the outside.

Torque Procedure
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.
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).
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
above.
6 Operate all machine functions and inspect the
hoses and fittings and related components to
be sure that there are no leaks.
2 Lubricate the O-ring before installation.

Test the Limit Switches
The tilt sensor sounds an alarm in the platform
when the incline of the machine exceeds
the rating on the serial plate.
Detecting limit switch malfunctions is essential to
safe machine operation. The drive limit switch is
used to restrict drive speed when the boom is
raised or extended. The drive enable limit switch
activates a signal light to inform the operator that
the platform is over the steering wheels, and stops
drive movement unless the drive enable override
switch is used. Improperly functioning limit
switches will allow the boom to raise and/or drive
into an unsafe position.
Select a level test area. The tilt
alarm should not be sounding prior
to test.
1 Turn the key switch to platform control and pull
out the Emergency Stop button to the ON
position at both the ground and platform
controls.

Controllers
Drive Controller Adjustments
The drive controller (joystick) is connected by a
control cable to the drive motor controller located
under the non-steer end drive chassis cover.
Maintaining the controllers at the proper setting is
essential to safe machine operation. Each
controller should operate smoothly and provide
proportional speed control through its entire range
of motion. For further information or assistance,
contact the Genie Industries Service Department.
Z-34/22: before serial number 153
Z-34/22N: before serial number 304
Do not adjust the controllers
unless the static battery supply
voltage is above 24V DC.
This procedure will require the use
of two multi-meters. One will be
used for measuring amperage and
the other for voltage.
Electrocution/burn hazard. Contact
with electrically charged circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
Individual trim potentiometers

Platform Leveling Slave Cylinder
How to Remove the Platform
The slave cylinder and the platform rotator are the
two primary supports for the platform. The slave
cylinder keeps the platform level through the
entire range of primary boom motion. It operates
in a closed-circuit hydraulic loop with the master
cylinder. The slave cylinder is equipped with
counterbalance valves to prevent platform
movement in the event of a hydraulic line failure.
1 Separate the foot switch wiring quick
disconnect plug from the platform toeboard.
2 Remove the platform control box mounting
fasteners, then lower the control box.
If your machine is equipped with
an air line to platform option, the
air line must be disconnected from
the platform before removal.
How to Remove the Slave
Cylinder
3 Place blocks under the platform for support and
carefully lower the platform on the blocks.
Before cylinder removal is
considered, bleed the slave
cylinder to be sure there is no
air in the closed loop hydraulic
circuit.
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation.
Refer to Section Two, Hydraulic
Hose and Fitting Torque
Specifications.
4 Remove the platform mounting fasteners and
remove the platform.
Component damage hazard.
Platform can be damaged if the
fasteners are overtightened.
