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.

Safety Rules
vi GS™-2669 DC • GS™-3369 DC • GS™-4069 DC Part No. 1306585GT
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
an
d 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 compone
nts 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 a
nd of ample capacity.
Be su
re 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 Specific ations
Hydraulic Oil Specifications
Hydraulic Fluid Specifications
Genie specifications require hydraulic oils which are
designed to give maximum protection to hydraulic
systems, have the abil
ity 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 aeration suppression
properties.

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 additi
ve
chemistry. When incompa
tible
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.

Torque Procedure
Torque Procedure
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-ring in Parker Seal Lok™ fittings and
hose end are custom-size O-rings. They are not
standard 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 the O-ring face seal 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. Refer to the appropriate torque chart
in this section.
6 Operate all machine functions and inspect the
hose, fittings and related components to
confirm there are no leaks.
JIC 37° fittings

2 Using a permanent ink marker, make a
reference mark on one the flats of the hex nut
and continue the mark onto the body of the
