SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section prescribes the proper and safe practices for
major areas of machine usage which have been divided
into three basic categories: Transporting, Pre-Operation
and Operation. In order to promote proper usage of the
machine, it is mandatory that a daily routine be estab-
lished based on instruction given in this section. A mainte-
nance program must also be established by a qualified
person and must be followed to ensure that the machine
is safe to operate.
The user/operator of the machine should not accept oper-
ating responsibility until this manual has been READ and
UNDERSTOOD, and operating instructions of the machine
under the supervision of an experienced and qualified
operator, has been completed. If there is a question on
application and/or operation, JLG Industries Product
Safety and Reliability should be consulted.
MODIFICATION OF THE MACHINE WITHOUT APPROVAL OF JLG
INDUSTRIES, OR CERTIFICATION BY A NATIONALLY RECOG-
NIZED TESTING LAB TO BE IN CONFORMITY WITH APPLICABLE
OSHA REGULATIONS, AND TO BE AT LEAST AS SAFE AS
BEFORE MODIFICATION, IS PROHIBITED AND IS A VIOLATION
OF OSHA RULES.
1.2 ELECTROCUTION HAZARD
Minimum safe approach distances (M.S.A.D.) to ener-
gized (exposed or insulated) power lines and parts.
DO NOT MANEUVER MACHINE OR PERSONNEL TO DISTANCE
LESS THAN M.S.A.D (SEE TABLE 1-1.). ASSUME ALL ELECTRI-
CAL PARTS AND WIRING ARE ENERGIZED UNLESS KNOWN
OTHERWISE.
THIS MACHINE DOES NOT PROVIDE PROTECTION FROM CON-
TACT WITH OR PROXIMITY TO AN ELECTRICALLY CHARGED
CONDUCTOR. MAINTAIN A CLEARANCE OF AT LEAST 10 FT.
(3M) BETWEEN ANY PART OF THE MACHINE AND ANY ELECTRI-
CAL LINE OR APPARATUS CARRYING UP TO 50,000 VOLTS. 1
FT. (0.3M) ADDITIONAL CLEARANCE IS REQUIRED FOR EVERY
ADDITIONAL 30,000 VOLTS OR LESS. ALLOW FOR PLATFORM
SWAY, ROCK OR SAG AND ELECTRICAL LINE SWAYING, (SEE
FOLLOWING TABLE) .
1.3 TRANSPORTING
Before transporting the machine the user/operator must
be familiar with the proper procedures for transporting the
machine, as well as the weight and size of the machine.
The user/operator should be familiar with the surrounding
work area and surface before transporting the machine.
The work area must be a smooth, firm surface on which
machine is capable of being leveled.
NOTE: Remember that the key to safe and proper usage is
common sense and its careful application.
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION AND ON MACHINE MAY RESULT IN MACHINE
DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY
VIOLATION.
