SECTION 1 - SAFETY PRECAUTIONS

SECTION 1. SAFETY PRECAUTIONS

1.1 GENERAL

This section prescribes the proper and sa fe practices for
major areas of machine usage which have been divided
into three basic categories: Driving, Operation, and Main­tenance. In order to promote proper usage of the
machine, it is mandatory that a daily routine be estab­lished based on the instructions given in this manual. A
maintenance program, using the in format ion prov ided in
the Service and Maintenance Man ual, must also be estab­lished 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 man­ual has been read and operation of the machine, under
the supervision of an experienced and qualified operator,
has been completed. Owner/user/operator/lessor/lessee
must be familiar with Sections 6, 7, 8, 9, and 10 of ANSI
A92.6 -1999. These sections contain the responsibilities of
the owner, users, operators, lessors and lessees concern­ing safety, training, insp ectio n, ma intena nce, a pplic ation
and operation. If there is a question on application and or
operation, JLG Industr ies should be consulted

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 espe­cially important when driving in close quarters.

The user should be familiar with the driving surface before
driving. The surface s hould be firm and level an d 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.

1.8 MAINTENANCE

This section contains the general safety precautions
which must be observed during maintenance of the aerial
work platform. It is of utmost impo rtance th at ma intenanc e
personnel pay strict attention to t hese warnings an d pre­cautions to avoid possible i njury to t hemselves or other s
or damage to the equipment. A maintena nce program
must be established by a qualified person and must be
followed to ensure that the machine is safe to operate.

MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY
A RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST
AS SAFE AS ORIGINALLY MANUFACTURED IS A SAFETY VIOLA­TION.

The specific precautions to be observe d during machine
maintenance are inserted at the appropriate point in the
manual. These precautions are, for the most part, those
that apply when servicing hydraulic and larger machine
component parts.

• NEVER WORK UNDER AN ELEVATED PLATFORM
UNTIL IT HAS BEEN RESTRAINED FROM MOVEMENT
WITH SAFETY PROPS, BLOCKING OR OVERHEAD
SLING.

• NEVER ALTER, REMOVE OR SUBSTITUTE ANY
ITEMS SUCH AS COUNTERWEIGHTS, SOLID TIRES,
BATTERIES, ETC. WHICH WOULD RED UCE THE
OVERALL WEIGHT OR BASE STABILITY OF THE
MACHINE.
