Safety Rules
Part No. 1272219 GS™-2669 RT • GS™-3369 RT • GS™-4069 RT vii
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 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 appr
oved
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
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.

Hydraulic Fluid Specifications
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,

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 it's
maximum allowable range. If the hydraulic fluid
temperature consistently exceeds 200°F / 90°C an
optional oil cooler may be required.
