other safety gear as required.
6. Load limits specified by the manufacturer shall
not be exceeded.
7. Instruction and warning placards must be legi-

9. Aerial lifts shall not be used near electric power
lines unless the lines have been de energized
or adequate clearance is maintained.
10. Employees using aerial lifts shall be instructed
on how to recognize and avoid unsafe condi-
tions and hazards.
11. Ground controls shall not be operated unless
permission has been obtained from personnel

SECTION 1 - SAFETY PRECAUTIONS
3120880 – JLG Sizzor – 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: Driving, Operation, and Main-
tenance. In order to promote proper usage of the
machine, it is mandatory that a daily routine be estab-
lished based on the instructions given in this manual. A
maintenance program, using the information provided in
the Service and Maintenance Manual, must also be estab-
lished by a qualified person and must be followed to
ensure that the machine is safe to operate.
The owner/user/operator/lessor/lessee of the machine
should not accept operating responsibility until this man-
ual has been read and operation of the machine, under
the supervision of an experienced and qualified operator,
has been completed. These sections contain the respon-
sibilities of the owner, users, operators, lessors and les-
sees concerning safety, training, inspection, maintenance,
application and operation. If there is a question on appli-
cation and or operation, JLG Industries should be con-
sulted
MODIFICATION OR ALTERATION OF AN AERIAL PLATFORM
SHALL BE MADE ONLY WITH PRIOR WRITTEN PERMISSION OF
THE MANUFACTURER.
1.2 DRIVING/TOWING/CARRYING
Before driving the machine the user must be familiar with
the drive, steer and stopping characteristics. This is espe-
cially important when driving in close quarters.
The user should be familiar with the driving surface before
driving. The surface should be firm and level and grades
should not exceed the allowable grade for the machine,
25%.
NOTE: Remember that the key to safe and proper usage is
common sense and its careful application.
It is not recommended that this machine be towed, except
in the event of a machine malfunction, a total machine
power failure, or for loading on a truck. Refer to Section 6
for emergency towing procedures.
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.
Carrying or loading the unit should be accomplished
using a forklift vehicle of suitable capacity with the forks
being positioned correctly at the indicated areas on the
machine frame. Refer to Section 4 for lifting information.

SECTION 1 - SAFETY PRECAUTIONS
1-2 – JLG Sizzor – 3120880
1.3 ELECTROCUTION HAZARD
DO NOT MANEUVER MACHINE OR PERSONEL INSIDE PROHIB-
ITED ZONE. ASSUME ALL ELECTRICAL PARTS AND WIRING ARE
ENERGIZED UNLESS KNOWN OTHERWISE.
NOTE: MAINTAIN M.S.A.D. FROM ALL OTHER CHARGED
LINES AND PARTS AS WELL AS THOSE SHOWN.
• MAINTAIN SAFE CLEARANCE FROM ELECTRICAL
LINES AND APPARATUS. ALLOW FOR PLATFORM
SWAY, ROCK OR SAG AND ELECTRICAL LINE SWAY-
ING. THE MACHINE DOES NOT PROVIDE PROTEC-
TION FROM CONTACT WITH OR PROXIMITY TO AN
ELECTRICALLY CHARGED CONDUCTOR.
• MAINTAIN A CLEARANCE OF AT LEAST 3 METERS
(10 FEET) BETWEEN ANY PART OF THE MACHINE
OR ITS LOAD AND ANY ELECTRICAL LINE OR APPA-
RATUS CARRYING UP TO 50,000 VOLTS. 0.3 METER
(ONE FOOT) ADDITIONAL CLEARANCE IS REQUIRED
FOR EVERY ADDITIONAL 30,000 VOLTS OR LESS.
