Section 1 - About Your Aerial Platform Read and Heed
SKYJACK is continuously improving and expanding product features on its equipment, therefore, specifications
and dimensions are subject to change without notice.
Mobile Elevating Work Platform (MEWP) and Aerial Platform Definition
A mobile device that has a positionable platform supported from ground level by a structure.
Purpose of Equipment
The SKYJACK SJIII DC Electric series MEWP are designed to transport and raise personnel, tools and materials to
overhead work areas.
Use of Equipment
The MEWP is a highly maneuverable, mobile work station. Work platform elevation and elevated driving must only
be done on a firm, level surface.
Manual
The operating manual is considered a fundamental part of the MEWP. It is a very important way to communicate
necessary safety information to users and operators. A complete and legible copy of this manual must be kept in
the provided weather-resistant storage compartment on the MEWP at all times.
Operator
The operator must read and completely understand both this operating manual and the safety panel label located
on the platform and all other warnings in this manual and on the MEWP. Compare the labels on the MEWP with the
labels found within this manual. If any labels are damaged or missing, replace them immediately.
Service Policy and Warranty
SKYJACK warrants each new SJIII Series work platform to be free of defective parts and workmanship for the first
24 months. Any defective part will be replaced or repaired by your local SKYJACK dealer at no charge for parts or
labor. Contact the SKYJACK Service Department for warranty statement extensions or exclusions.
Optional Accessories
The SKYJACK MEWP is designed to accept a variety of optional accessories. These are listed under “Standard and
Optional Features” in Table 4.1.
Operating instructions for these options (if equipped) are located in Section 3 of this manual.
For options not listed under “Standard and Optional Features,” contact the SKYJACK Service Department at
(: 61 (0) 28786 3200

Safety Rules Section 1 - About Your Aerial Platform
WARNING
Failure to comply with your required responsibilities in the use and operation of the MEWP could
result in death or serious injury!
Operator Safety Reminders
A study conducted by St. Paul Travelers showed that most accidents are caused by the failure of the operator to
follow simple and fundamental safety rules and precautions.
You, as a careful operator, are the best insurance against an accident. Therefore, proper usage of this MEWP is
mandatory. The following pages of this manual should be read and understood completely before operating the
MEWP.
Common sense dictates the use of protective clothing when working on or near machinery. Use appropriate safety
devices to protect your eyes, ears, hands, feet and body.
Any modifications from the original design are strictly forbidden without written permission from SKYJACK.
Electrocution Hazard
This MEWP is not electrically insulated. Maintain a Minimum Safe Approach Distance (MSAD) from energized
power lines and parts as listed below. The operator must allow for the platform to sway, rock or sag. This MEWP
does not provide protection from contact with or proximity to an electrically charged conductor.
DO NOT USE THE MEWP AS A GROUND FOR WELDING.
DO NOT OPERATE THE MEWP DURING LIGHTNING OR STORMS.
DO NOT OPERATE THE MEWP NEAR POWER LINES. MAINTAIN A MININUM SAFE APPROACH
DISTANCE (MSAD) FROM ENERGIZED POWER LINES.

Safety Precautions
Know and understand the safety precautions before going on to next section.
WARNING
Failure to heed the following safety
precautions could result in tip over,
falling, crushing, or other hazards leading
to death or serious injury.
• KNOW all national, state or territorial/provincial
and local rules which apply to your MEWP and
jobsite.
• TURN main power disconnect switch “ ” off
when leaving the MEWP unattended. Remove
the key to prevent unauthorized use of the MEWP.
• WEAR all the protective clothing and personal
safety devices issued to you or called for by job
conditions.
• DO NOT wear loose clothing,
dangling neckties, scarves,
rings, wristwatches or other
jewelry while operating this lift.

boundaries of the guardrails.
• DO NOT raise the MEWP or
operate elevated in windy or
gusty conditions that exceed
the limits specified in Section 4,
Table 4.4.
• DO NOT increase the lateral
surface area of the platform.
Increasing the area exposed
to the wind will decrease
MEWP stability. Avoid tenting.
• DO NOT drive elevated on a
soft or uneven surface.

MEWP.
• IF OPERATION IN AREAS
WITH HOLES OR DROP-
OFFS IS ABSOLUTELY
NECESSARY, elevated driving
shall not be allowed. Position
the MEWP horizontally only
with the platform fully-lowered.
After ensuring that all 4 wheels
or outriggers (if equipped)
have contact with a firm, level
surface, the MEWP can be
elevated. After elevation, the
drive function must not be
activated.
• DO NOT elevate or drive
elevated on a slope. Elevated
driving must be done on a
firm, level surface.
• DONOT ascend or descend
a grade when elevated.
When fully-lowered, ascend
or descend grades not
exceeding those listed in
Table 4.3a and Table 4.3b.

It is the responsibility of the operator to read, completely understand and follow all instructions and warnings
contained in this operating manual and on the aerial platform.
2.2 Component Identification
The following descriptions are for identification,
explanation and locating purposes only.
2.2-1 Main Power Disconnect Switch
This switch is located at the rear of the base.

Figure 2-1. Main Power Disconnect Switch
1. Main Power Disconnect Switch - This switch,
when in “ ” off position, disconnects power to
all circuits. Switch must be in “ ” on position to
operate any circuit. Turn switch “ ” off when
transporting MEWP.
2.2-2 Tilt Alarm
The MEWP is equipped with a device which senses
when the MEWP is on a slope in any direction. It is
designed to prevent driving and activate audible and
visual alarms when MEWP is on a slope greater than a
predetermined limit.
WARNING
If the tilt alarm sounds and the
platform does not, or only partially
raises, immediately lower the platform
completely and ensure that the MEWP is
on a firm level surface.
2.2-3 Lowering Alarm
The MEWP is equipped with an audible alarm which
sounds while the MEWP is lowering.
NOTE
On MEWP with certain options, a flashing
amber light will accompany this alarm.
2.2-4 Load Sensing System
This system is a safety device that will prevent any
normal movement of the MEWP from a stationary
working position after the rated load is reached and
exceeded. Refer to Table 4.4 for maximum platform
capacities.
• When 90% of the rated load is reached:
The red power indicator light on the platform
control console flashes.
• When the rated load is reached:
An audible alarm sounds for approximately 2
seconds, 5 times per minute.
• When the rated load is exceeded:
The flashing light and audible alarm continue
and all electrically controlled MEWP movement
functions stop. To resume normal operation,
remove the overload from the platform.
• If the MEWP comes in contact with an overhead
obstruction:
The platform could become overloaded and all
functions would stop. Release of the platform
from this situation can only be effected by use
of the emergency lowering system. Refer to
Section 2.6.
NOTE
After reaching full extension and upon
lowering, the MEWP could stop and take
an overload reading. Return the controller
to the neutral center position, and release
the enable trigger switch. If the MEWP
is overloaded, the flashing light and
audible alarm continue and all electrically
controlled MEWP movement functions
stop. To resume normal operation, remove
the overload from the platform.

• Wheel/Tire Assembly
The MEWP is either equipped with solid
rubber tires or foam-filled tires. Tire and/or
wheel failure could result in an MEWP tip-
over. Component damage may also result if
problems are not discovered and repaired in
a timely fashion.
- Check all tire treads and sidewalls for
cuts, cracks, punctures and unusual
wear.
- Check each wheel for damage and
cracked welds.
- Check each lug nut for proper torque to
ensure none are loose.
- Check wheel motor assembly for loose
or missing parts and signs of visible
damage.
- Ensure wheels are aligned and true
vertically and horizontally.
WARNING
Intermixing tires of different types or
using tires of types other than those
originally supplied with this equipment
can adversely affect stability. Therefore,
replace tires only with the exact Skyjack-
approved type. Failure to operate
with matched approved tires in good
condition may result in death or serious
injury.
