Electrical Hazard
■Electrical Hazard Warning
THE MHP15/44HD AERIAL WORK PLATFORM, IN STANDARD
CONFIGURATION, IS NOT ELECTRICALLY INSULATED.
If the platform, booms, or any other conductive part of a MHP15/44HD contacts a high-voltage electrical
conductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine.
GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES
(M.S.A.D) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,
ON THE NEXT PAGE.
Be sure to allow for sag and sway in the wires and the work platform.
If a MHP15/44HD comes in contact with a live electrical conductor, the entire machine can be charged.
If that happens, you should remain on the machine and not contact any other structure or object within
reach. That includes the ground, adjacent buildings, poles, and any object not a part of the MHP15/44HD.
Such contact could make your body a conductor to the other object creating an electrical shock hazard re-
sulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the MHP15/44HD until you are sure the electricity has been turned off.
If a MHP15/44HD is in contact with a live conductor, the platform operator MUST warn others on the
ground in the vicinity of the MHP15/44HD to STAY AWAY from the machine, since their bodies can also
form a path for electricity to ground thus creating an electrical shock hazard with possible
ELECTROCUTION and DEATH.
DO NOT attempt to operate the MHP15/44HD ground controls when the platform, booms, or any other
conducting part of a MHP15/44HD is in contact with electrical wires or if there is an immediate danger of
such contact.
Regard all conductors as energized.
Personnel working on or near a MHP15/44HD must be continuously aware of electrical hazards, recogniz-
ing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

■Minimum Safe Approach Distance
The MHP15/44HD is an all metal boom, NOT ELECTRICALLY INSULATED, aerial work platform. DO
NOT operate it near ELECTRICAL conductors. Regard all conductors as being energized. Use the table
and illustration below to determine safe clearance from electrical conductors. (Table 1 and Figure 3, be-
low, are from ANSI/SIA A92.5–1992 Standard, reprinted with permission of Scaffold Industry Association.)

materials inside prohibited zone.
- Maintain M.S.A.D. From all energised lines and parts
as well as those shown.

This manual provides information for safe and
proper operation of the aerial platform.
Read and understand the information in this
Operator’s manual before operating this machine
on a job site.
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
product information at the time of publication.
Snorkel reserves the right to make product
changes at any time without obligation.

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 MHP aerial platform has built-in safety fea-
tures and has been factory tested for compliance
with Snorkel specifications and industry standards.
However, any personnel lifting device can be po-
tentially dangerous in the hands of untrained or
careless operators.
Training is vitally important and must be performed
under the direction of a QUALIFIED person. You
must display proficiency in knowledge and actual
operation of the MHP before using it on a job site.
Before operation of the MHP you must read and un-
derstand the operating instructions in this manual
as well as the decals, warnings, and instructions on
the machine itself.
Before operating the MHP you must be
AUTHORIZED by the person in charge to do so
and the operation of the MHP must be within the
scope of the machine specifications.
The potential for an accident increases when
the aerial platform is operated by personnel
who are not trained and authorised. death or
serious injury can result from such
accidents.
Read and understand the information in this
manual and on the placards and decals on
the machine before operating the MHP on
the job.
■Maintenance
Every person who maintains, inspects, tests, or
repairs these machines, and every person
supervising any of these functions, must be
properly trained and qualified to do so.
This Operators Manual provides a Pre-operational
Inspection procedure that will help you keep your
MHP in good operating condition.
Do not perform other maintenance unless you are a
trained mechanic, qualified to work on the MHP.
Call qualified maintenance personnel if you find
problems or malfunctions.
Do not modify this machine without written
approval from the Engineering Department of
Snorkel. Modification may void the warranty,
adversely affect stability, or affect the operational
characteristics of the MHP.
■Responsibilities of Parties
It is imperative that all owners and users of
the MHP read, understand, and conform to
all applicable regulations.
Ultimate compliance to OSHA regulations is the
responsibility of the user and their employer.
ANSI Standard A92.6 clearly identifies
requirements of all parties who might be
involved with Self-Propelled Elevating Work
Platforms.
AUSTRALIAN / NZ STANDARD 2550-10 Also
identifies the requirements of all parties who
might be involved with Boom-Supported
Elevating Work Platforms.
NOTE - Standards
It is the responsibility of the owner to ensure that
the person operating the MHP15/44HD is
provided with all the relevant information relating
to standards and codes of practice applicable in
their region.
❑In summary
