Snorkel S2646E User manual

February 2011
Serial number 1107120411 and after
Part Number 0410051
MANUAL
OPERATOR’S

The aerial platform is not electrically insulated. Death or serious injury will result from contact
with, or inadequate clearance from, an energized conductor.
Do not go closer than the Minimum Safe Approach Distance as dened by ANSI standards.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, scissors structure, or any part of the aerial platform contacts a high-voltage electrical
conductor, the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This in-
cludes the ground, adjacent buildings, poles, and any other objects that are not part of the aerial
platform.
Such contact could make your body a conductor to the other object, creating an electrical shock
hazard resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground
personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock
hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, scissors structure, or any part of
the aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate
danger of such contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recogniz-
ing that death or serious injury can result from contact with an energized conductor.

Operator’s Manual
This manual provides information for safe and proper op-
eration of the aerial platform. Because it covers more
than one model, some figures may only represent what
is actually on the machine. Read and understand the
information in this Operator’s Manual before operating
the aerial platform on the job.
Additional copies of this manual may be ordered from
Snorkel. Supply the model and manual part number from
the front cover to assure that the correct manual will be
supplied.
All information in this manual is based on the latest prod-
uct information at the time of publication. Snorkel reserves
the right to make product changes at any time without
obligation.
SafetyAlerts
A safety alert symbol is used throughout this manual to
indicate danger, warning, and caution instructions. Fol-
low these instructions to reduce the likelihood of per-
sonal injury and property damage. The terms danger,
warning, and caution indicate varying degrees of personal
injury or property damage that can result if the instruc-
tion is not followed.
Danger
Indicates an imminently hazardous situation which,
if not avoided, will result in death or serious injury.
This signal word is to be used in the most extreme
situations.
Warning
Indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury.
Caution
Indicates a potentially hazardous situation which, if
not avoided, may result in minor or moderate in-
jury. It may also be used to alert against unsafe
practices.
Notes
Notes are used to provide special information or helpful
hints to assist in aerial platform operation, but do not
indicate a hazardous situation.
Operation
The aerial platform has built-in safety features and has
been factory tested for compliance with Snorkel specifi-
cations and industry standards. However, any personnel
lifting aerial platform can be potentially dangerous in the
hands of untrained or careless operators.
Warning
The potential for an accident increases when the
aerial platform is operated by personnel who are
not trained and authorized. Death or serious injury
can result from such accidents. Read and under-
stand the information in this manual and on the plac-
ards and decals on the machine before operating
the aerial platform on the job.

Chapter 1 – Introduction
2S2646/S3246 – 0410051
Training is essential and must be performed by a quali-
fied person. Become proficient in knowledge and actual
operation before using the aerial platform on the job. You
must be trained and authorized to perform any functions
of the aerial platform. Operation of the aerial platform must
be within the scope of the machine specifications.
The operator bears ultimate responsibility for following all
manufacturer’s instructions and warnings, regulations and
safety rules of their employer and/or any state or federal
law.
Maintenance
Every person who maintains, inspects, tests, or repairs
the aerial platform must be qualified to do so. Following
the daily prestart inspection in this Operator’s Manual
will help keep the aerial platform in optimum working con-
dition. Other maintenance functions must be performed
by maintenance personnel who are qualified to work on
the aerial platform.
Do not modify this aerial platform without prior written
consent of the Snorkel Engineering Department. Modifi-
cation may void the warranty, adversely affect stability, or
affect the operational characteristics of the aerial plat-
form.
Manual of Responsibilities
All owners and users of the aerial platform must read,
understand, and comply with all applicable regulations.
Ultimate compliance to OSHA regulations is the respon-
sibility of the user and their employer.
ANSI publications clearly identify the responsibilities of
all personnel who may be involved with the aerial plat-
form. A reprint of the “Manual of Responsibilities for Deal-
ers, Owners, Users, Operators, Lessors and Lessees of
ANSI/SIAA92.6-1999Self-PropelledElevatingWorkPlat-
forms” is available from Snorkel dealers or from the fac-
tory upon request.
