Introducti on Introduction
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.

Safety Rules
vi GS-84 • GS-90 Part No. 1272222GT
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 poss
ible
injury or death.
Indicates a imminently
hazardous situation which, if
not avoided, will result in death
or serious in
jury.
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 clo
thing if the
situation warrants it.
Be aware of potential crushing
hazards such as moving parts, free
sw
inging 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 ba
ttery
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 compon
ents and cause
damage.
Be sure any forklift, overhead crane or
other lifting or supporting de
vice 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 s
ure that fasteners intended for
one time use (i.e., cotter pins and self
-
locking nuts) are not r
eused. 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 Specifications
Hydraulic Fluid Specifications
Genie specific
ations require hydraulic oils which are
designed to give maximum protection to hydraulic
systems, have the ability to
perform over a wide

exceed 140. They should provide excellent antiwear,

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
da
mage.
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 b
ase additive
chemistry. When incompatible
fluids are mixed, insoluble
materials may form and deposit
in the hydraulic system,
plugging hydraulic lines, fil
ters,
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.

consistently below 0°F / -18°C.
Note: Do not operate the machine when the
ambient temperature is below -20°F / -29°C with
Rando HD Premium MV.
