SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section outlines the necessary precautions for proper
and safe machine usage and maintenance. In order to
promote proper machine usage, it is mandatory that a
daily routine is established based on the content of this
manual. A maintenance program, using the information
provided in this manual and the Service and Maintenance
Manual, must also be established by a qualified person

•Never slam a control switch or lever through neutral to
an opposite direction. Always return switch to neutral
and stop before moving the switch to the next function.
Operate controls with slow and even pressure.
•Hydraulic cylinders should never be left at end of travel
(fully extended or fully retracted) before shutdown or
for long periods of time. Always “bump”control in
opposite direction slightly when function reaches end
of travel. This applies both to machines in operation or
in the stowed position.
•Do not allow personnel to tamper with or operate the
machine from the ground with personnel in the plat-
form, except in an emergency.
•Do not carry materials directly on platform railing
unless approved by JLG.
•When two or more persons are in the platform, the
operator shall be responsible for all machine opera-
tions.
•Always ensure that power tools are properly stowed
and never left hanging by their cord from the platform
work area.
•When driving, always position boom over rear axle in
line with the direction of travel. Remember, if boom is
over the front axle, the direction of steer and drive will
be opposite from normal operation.
•Do not assist a stuck or disabled machine by pushing,
pulling, or by using boom functions. Assist only by
pulling at the chassis tie-down lugs.
•Do not place boom or platform against any structure to
steady the platform or to support the structure.
•Stow boom and shut off all power before leaving
machine.
