Service Manual - First Edition
SAFETY RULES
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.
Red—used to indicate the
presence of an imminently
hazardous situation which, if not
avoided, will result in death or
serious injury.
Orange—used to indicate the
presence of a potentially
hazardous situation which, if not
avoided, could result in death or
serious injury.
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.
Yellow without safety alert
symbol—used to indicate the
presence of a potentially
hazardous situation which, if not
avoided, may result in property
damage.
Green—used to indicate operation
or maintenance information.
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 and 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 such as 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 that your workshop or work area
is properly ventilated and well lit.
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 .

Theory of Operation
Power Source
The Genie GS-1530 and GS-1930 machines are
powered by four six-volt (255 AH) batteries. The
four batteries are wired in series to produce 24
volts.
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.
Activating a machine function is accomplished by
actuating or moving a switch and/or control handle,
which sends voltage to the ECM. The ECM then
sends the signal to the appropriate directional
control valve. The directional valve determines
which direction the hydraulic fluid will travel.
Computer software determines the volume of fluid
in relation to the proportional valve input voltage.
Electrical System
Limit switches are found in various locations on the
machine. The function of a limit switch is to
communicate the operating position of the machine
to the ECM (Electronic Control Module). When a
change in signal is received from a limit switch, the
ECM responds by limiting the drive speed to 0.5
miles per hour (0.8 km/h), according to the default
settings in the ECM software.
Machine Controls
The GS-1530 and GS-1930 machines are
equipped with operational controls which are found
in two locations: the ground controls, located on
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 platform up/down functions are
available at the ground controls.
The ECM uses input from the ground or platform
controls to activate the various machine functions.
The ECM has predetermined settings for the
various machine functions.
The joystick is fitted with a 5000 ohm
potentiometer. With the joystick in the neutral
position, the potentiometer will measure 2730
ohms. These signals are sent to the multiplex card,
then down to the ECM to control the voltage
supplied to the proportional valve. Two
microswitches mounted on the joystick tell the
ECM the drive direction desired. A thumb rocker
switch on the top of the joystick is used for
steering.
Mounted on the platform control box lid of
machines before serial number 17408 are buttons
and a switch that, when activated, sends a signal to
the ECM through the multiplex card. On machines
after serial number 17407, the platform control box
lid has a decal/membrane pad. This is a touch-
activated pad incorporating wiring, switches and
LEDs that are resistant to the environment.
Activating any of the buttons on the pad will send a
signal to the ECM through the multiplex card.
A diagnostic display is located at the battery pack
side of the machine to aid in troubleshooting. If the
machine malfunctions, a fault code will be shown in
the display window.
Washing electronic components is not suggested.
Instead, use compressed air to remove debris from
these components.
Component damage hazard. Avoid
shock or impact to the ECM.
Internal damage may not be visible
from the outside.

Hydraulic Hose and Fitting Torque Specifications
Your machine is equipped with either 37° flared fittings and hose ends OR Parker Seal-Lok®fittings and
hose ends. Machines that utilize Parker Seal-Lok®hoses and fittings require that the fittings and hose
ends be torqued to specification when they are removed and installed or when new hoses or fittings are
installed. Machines equipped with 37° flared fittings and hose ends do not need to be torqued to these
specifications.
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 a custom-size O-ring. They
are not a standard SAE size
O-ring. They are available in the
O-ring field service kit (Genie part
number 49612).

Table A Procedures
A-1
Inspect the Operator’s and
Safety Manuals
Maintaining the operator’s and safety manuals in
good condition is essential to safe machine
operation. Manuals are included with each
machine and should be stored in the container
provided in the platform. An illegible or missing
manual will not provide safety and operational
information necessary for a safe operating
condition.
1 Check to be sure the storage container is
present and in good condition.
2 Check to make sure that the operator’s,
responsibilities and safety manuals are present
and complete in the storage container in the
platform.
3 Examine the pages of each manual to be sure
that they are legible and in good condition.
4 Always return the manuals to the storage
container after use.
Contact your authorized Genie
distributor or Genie Industries if
replacement manuals are needed.
A-2
Inspect the
Decals and Placards
Maintaining all of the safety and instructional
decals and placards in good condition is
mandatory for safe machine operation. Decals
alert operators and personnel to the many
possible hazards associated with using this
machine. They also provide users with operation
and maintenance information. An illegible decal
will fail to alert personnel of a procedure or hazard
and could result in unsafe operating conditions.
1 Refer to the Decals section in the appropriate
Genie GS-1530 & Gemie GS-1930 Operator's
Manual and use the decal list and illustrations
to determine that all decals and placards are in
place.
2 Inspect all decals for legibility and damage.
Replace any damaged or illegible decal
immediately.
Contact your authorized Genie
distributor or Genie Industries if
replacement decals are needed.
