SECTION 1 - SAFETY PRECAUTIONS
3120848 – JLG Lift – 1-1
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 personnel 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
REGULATIONS AND TO BE AT LEAST AS SAFE AS BEFORE MOD-
IFICATION, IS PROHIBITED.
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 3M (10
FT.) BETWEEN ANY PART OF THE MACHINE AND ANY ELECTRI-
CAL LINE OR APPARATUS CARRYING UP TO 50,000 VOLTS. 0.3M
(1 FT.) 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 MACHINE
Before transporting (hauling) the machine the user/opera-
tor must be familiar with the proper procedures for trans-
porting the machine (see Section 4-5), 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 firm surface capable of support-
ing the combined weight of the transport vehicle and the
machine.
NOTE: Remember that the key to safe and proper usage is
common sense and its careful application.
ALWAYS RELEASE THE DRIVE MOTOR BRAKES ON THE
MACHINE WHEN MANUALLY PUSHING, PULLING, OR WHEN
TRANSPORTING MACHINE BY FORK-LIFT TRUCK. THIS WILL
ALLOW THE REAR DRIVE WHEELS, GEAR BOX DRIVE SHAFT
AND GEARS TO ROTATE FREELY PREVENTING ANY DAMAGE TO
THE DRIVE SYSTEM.
IF MACHINE IS PLACED ON A TRANSPORT VEHICLE, RE-
ENGAGE THE BRAKES IN COMBINATION WITH PROPER
MACHINE TIE DOWN, TO RESTRAIN MACHINE FROM ANY MOVE-
MENT DURING TRANSPORT.
ALWAYS REMEMBER TO RE-ENGAGE THE BRAKE SYSTEM
BEFORE OPERATING MACHINE.
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION AND ON MACHINE COULD RESULT IN MACHINE
DAMAGE, PERSONAL INJURY OR DEATH AND IS A SAFETY VIO-
LATION.
