3.3 OPERATING CHARACTERISTICS AND
LIMITATIONS
General
A thorough knowledge of the operating characteristics
and limitations of the machine is always the first require-
ment for any user, regardless of user’s experience with
similar types of equipment.
Placards
(See Figure 3-5., 3-6., 3-7., 3-8., & 3-9.)
Important points to remember during operation are pro-
vided at the control stations by DANGER, WARNING,
CAUTION, IMPORTANT and INSTRUCTION placards. This
information is placed at various locations on the machine
for the express purpose of alerting personnel of potential
hazards constituted by the operating characteristics and
load limitations of the machine. See the Foreword at the
start of this manual for a definition of the seriousness of
each of the above placard types. See decal location fig-
ures in this section for decals which apply to this machine.
Capacities
Raising the platform above the stowed position is based
on the following criteria:
• The machine is positioned on a smooth, firm level sur-
face.
• The load is within manufacturer’s rated capacity.
• All machine systems are functioning properly.
Stability
This machine, as originally manufactured by JLG and
when operated within its rated capacity on a smooth, firm
and level supporting surface, provides a stable aerial plat-
form for all platform positions.
3.4 CONTROLS AND INDICATORS
Ground Controls
(See Figure 3-1.)
NOTE: When the machine is not being used or when charg-
ing the battery, set the POWER PLAT/OFF/ GRND
KEY SWITCH to OFF to prevent draining the batter-
ies. For information on battery charging see SEC-
TION 2-7, Battery Charging.
1. POWER PLAT/OFF/GROUND KEY SWITCH
A key operated power PLAT/OFF/GROUND switch
located in the upper access hole of the rear cover
(on back of machine), controls power to all functions
on the machine. When left unattended, removing the
key will prevent unauthorized machine use. If
machine is equipped with optional Programmable
Security Lock see Section 5 for details on use.
2. PLATFORM UP/DOWN (GROUND CONTROL)
The ground operated platform control switch is
located next to the hydraulic reservoir in the lower
access hole of the rear cover. This three position
toggle switch will raise (lift up) and lower (lift down),
the platform from the ground control position when
the PLAT/OFF/GRND key switch is set to the GRND
(ground) position.
3. EMERGENCY STOP BUTTON
An EMERGENCY STOP (red button) is mounted on
both the ground control station and the platform
controller. When either button is depressed, all
machine functions will stop. To re-activate power to
the machine, turn button clockwise to RESET the
emergency stop button.
4. EMERGENCY/MANUAL DESCENT KNOB
This (RED knurled) knob, located on the electric/
hydraulic pump-motor unit in the lower access hole
of the rear cover provides for lowering of the plat-
form in the event of an emergency or power failure.
Turn knob (counterclockwise) to open the valve and
lower the platform. This valve must be closed
(turned all the way clockwise) for normal operation
of the machine. (Refer to Section 6 for Emergency
Descent operating procedures.)
5. HYDRAULIC OIL RESERVOIR
The hydraulic oil reservoir is housed inside the lower
access hole in the rear cover. Check the hydraulic oil
level visually by observing the oil level in the reser-
voir as compared to the FILL TO LINE indicator on
the side of the reservoir. Hydraulic oil can be added
if necessary through the OIL FILL CAP on top of the
reservoir. DO NOT OVERFILL.
