Introduction
Important
Read, understand and obey the safety rules and
operating instructions in the Genie GS-2032 and
GS-2632 and GS-2046 and GS-2646 and GS-3246
Operator's Manual before attempting any
maintenance or repair procedure.
This manual provides detailed scheduled
maintenance information for the machine owner
and user. It also 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
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.
iv
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.
Workplace Safety
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.

3 Working clockwise on the body hex fitting, make
a second mark with a permanent ink marker to

tighten the joint after it has been
loosened.
