Purpose Of Equipment
SECTION 1
INTRODUCTION
Lifting Mechanism
The SKYJACK SJIII Series Work Platform is designed
to transport and raise personnel, tools and materials
to overhead work areas.
Use Of Equipment
The work platform (Figure 1-1.) is a highly
maneuverable, mobile work station. Lifting and driving
MUST be on a flat, level, compacted surface.
Warnings
The operator MUST read and completely understand the
safety panel label located on the platform and ALL other
warnings in this manual and on the work platform.
Compare the labels on the work platform with the labels
found throughout this manual. If any labels are damaged
or missing, replace them immediately.
Description
The work platform consists of three major assemblies,
the platform, lifting mechanism and the base. An
operator’s control box is mounted on the platform
railing. Auxiliary and emergency controls are located
at the base.
Platform
The platform is constructed of a tubular support frame,
a skid-resistant deck surface, and 40 inch to 43-1/2
inch (1016-1105mm) high railings (depending on
model) with 6" (152mm) toe boards and mid-rails. The
platform can be entered from the rear through an entry
chain or optional spring-returned gate with latch. The
platform is also equipped with an extension platform.
Manual Storage Box
Base
The base is a rigid one-piece weldment which supports
two swing-out trays. On Models 3015, 3219, 3220,
4620, 4626, 4830 and 4832 a mechanically actuated
angle, located under the outside of the trays, rotates
when lifting. This mechanism provides pothole
protection for elevated driving. One tray contains the
hydraulic and electrical components. The other tray
contains the battery charger and four (4) 6 volt
batteries. On Models 3015 and 3219; the front axle
has two hydraulic motor-driven wheels , steerable by
a hydraulic cylinder. The rear axle is fixed and has
two spring-applied hydraulically-released parking
brakes. On Models 3220, 4620, 4626, 4830, 4832,
6826 and 6832 The front axle has two non-driven
wheels, steerable by a hydraulic cylinder. The rear
axle has two hydraulic motor-driven wheels and two
spring-applied hydraulically-released parking brakes.
Lowering Warning System (CE only)
Models 3015, 3219, 3220, 4620, 4626,4830 and
4832 are equipped with a lowering warning system
as standard equipment.
Scissor Guards (CE only)
This weather resistant box is
mounted at the front of the
platform directly below the safety
panel. It contains the Operating
Manual, the optional Operating/
Maintenance and Parts Manual
and
other
important
documentation. The Operating
Manual for this make and model
work platform MUST remain with
the work platform and should be
stored in this box.
Models 6826 and 6832 are equipped with rigid
scissor guards mounted on the base as standard
equipment.
Serial Number Nameplate
Operator’s Control Box
A removable control box, mounted at the right front
of the platform, contains controls for work platform
motion and emergency stopping.
SJIII Series - The COMPACTS
& CONVENTIONALS 118942AD
The lifting mechanism is constructed from steel tubing
making up a scissor-type assembly. The scissor-type
assembly is raised and lowered by single-acting
hydraulic lift cylinders. A pump, driven by a motor,
provides hydraulic power to the lift cylinder. A safety
bar located at the front of the lifting mechanism
prevents (when properly positioned) the scissor-type
assembly from being lowered while maintenance or
repairs are being performed within the lifting mechanism.
The serial number nameplate, located at the rear of
the machine, lists the model number, serial number,
machine weight, drive height, capacity and maximum
no. of persons, maximum speed, maximum manual
force, maximum incline, platform height, voltage,
system pressure, lift pressure, ground pressure (tire
contact pressure), and date manufactured. Use this
information for proper operation and maintenance and
when ordering service parts.

1.
Check for a firm AC connection at the charger
receptacle. Connect the charger cord to the AC
wall plug to turn the charger on. Refer to charger
nameplate for voltage requirements.
2.
Charge batteries. DO NOT leave charger
unattended for more than two consecutive days.
Severe overcharging and battery damage will
result if charger fails to turn off.
Apply The AC power. The charger will start immediately (the transformer will hum and fan will come on).
The red LED will come on. The ammeter will show
charging current.
3.
Disconnect charger from external power source.
The current will be high for approximately 30 minutes
then it will taper off. If the current does not taper off,
disconnect the charger and check the batteries for a
shorted cell.

When the battery bank voltage reaches approximately
30 volts DC, the yellow flashing LED will illuminate.
This indicates that the charger has now entered a
timed equalizing cycle. After completing the 3.5 hour
cycle, the charger will shut off and the green LED will
come on to indicate a complete charge.
If a shorted battery cell prevents the charger from raising the battery voltage to approximately 30 VDC to
start the equalization timer, a second timer will shut
down the charger after 16 hours of continuous charging. When this happens, the flashing yellow LED will
come on to notify the user that the battery bank should
be inspected for a shorted/damaged cell.

MAC Charger
As the charge cycle continues, which can last between 1 1/2 hours and 16 hours for a complete cycle,
depending on the state of charge of the batteries, the
“80%” light will come on and the “INCOMPLETE” light
will go off. When voltage of the batteries reaches approximately 30 volts, the “80%” light will go off and
the “CHARGE COMPLETE” light will come on. This
light will remain on even after the charger is turned
off by the electronic control. After the charger turns
off, the “CHARGE COMPLETE” light will indicate to
the operator that the batteries are fully charged.

5 RED L.E.D. ............................ ABNORMAL CYCLE
This charger is equipped with an electronic circuit
that will completely recharge the batteries and automatically turn off after the charge cycle is complete.
If the “80% CHARGE” light continues to stay on after
the charge cycle is complete, this indicates to the
operator that the batteries are not capable of attaining a full charge.
If the “INCOMPLETE” light remains on after the charge
cycle is complete, this indicates to the operator that
the batteries are not capable of attaining even an 80%
charge.
If either the “80% CHARGE” or “INCOMPLETE” light
remain on after the charge cycle is complete, the batteries should be inspected for problems.
Refer to the “Battery Service” section for proper battery inspection and maintenance procedures.
The function of the L.E.D. indicators is as follows:
When the AC power is connected to the charger, the
L.E.D.’s will flash several times then flash independently to check the light circuits. After the flashing
sequence is complete the “INCOMPLETE” light will
come on. Five seconds later , the “CHARGER ON”
light will come on and at the same time, the ammeter
will indicate how much current is going to the batteries.
