WARNING
Failure to comply with your required responsibilities in the use and operation of the aerial platform
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 aerial
platform is mandatory. The following pages of this manual should be read and understood completely before
operating the aerial platform.
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.
Safety Rules

SJIII DC Electric
Safety Rules Section 1 - About Your Aerial Platform

Electrocution Hazard
This aerial platform 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 aerial platform does not provide protection from contact with or proximity to an electrically charged conductor.
Per ANSI A92.6-2006 8.10(7)
“The operator shall perform only that work for which he or she is qualified, in compliance with all applicable safety
related work practices intended to prevent electric shock covered by the Code of Federal Regulations (CFR)
1910.333. The operator’s level of competence shall be established only by persons qualified to do so. Operators
shall maintain the appropriate minimum approach distance (MAD) from energized power lines and parts covered
by CFR 1910.333 (c).”
Unqualified persons must maintain a minimum approach distance of 10 feet from any energized power line up to
50 kV. Energized power lines over 50 kV require a greater minimum approach distance to be maintained. Refer to
CFR 1910.333.
As per CSA B354.2-01
“The operator shall maintain the minimum safe approach distance (MSAD) from energized conductors at all times
in accordance with the authority having jurisdiction.”
DO NOT USE THE AERIAL PLATFORM AS A GROUND FOR WELDING.
DO NOT OPERATE THE AERIAL PLATFORM DURING LIGHTNING OR STORMS.
DO NOT OPERATE THE AERIAL PLATFORM NEAR POWER LINES. MAINTAIN A MINIMUM 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 aerial platform
and jobsite.
• TURN main power disconnect switch “ ” off
when leaving the aerial platform unattended.
Remove the key to prevent unauthorized use of
the aerial platform.
• 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.
• AVOID entanglement with
ropes, cords or hoses.
• AVOID falling. Stay within the
boundaries of the guardrails.
• DO NOT raise the aerial
platform or operate elevated in
windy or gusty conditions that
exceed the limits specified in
Section 4, Table 4.5.
• DO NOT increase the lateral
surface area of the platform.
Increasing the area exposed
to the wind will decrease
aerial platform stability. Avoid
tenting.
• DO NOT drive elevated on a
soft or uneven surface.
• DO NOT elevate the aerial
platform if it is not on a firm,
level surface.
• DO NOT drive elevated near
depressions or holes of any
type, loading docks, debris,
drop-offs or surfaces that may
affect the stability of the aerial
platform.
• IF OPERATION IN AREAS
WITH HOLES OR DROP-
OFFS IS ABSOLUTELY
NECESSARY, elevated driving
shall not be allowed. Position
the aerial platform 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 aerial
platform 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 up to
maximum rated inclines listed
in Table 4.

SJIII DC Electric
Safety Rules Section 1 - About Your Aerial Platform

• DO NOT operate on surfaces not capable of
holding the weight of the aerial platform including
the rated load, e.g. covers, drains, and trenches.
• DO NOT operate an aerial
platform that has ladders,
scaffolding or other devices
mounted on it to increase
its size or work height. It is
prohibited.
• DO NOT exert side forces on
aerial platform while elevated.
• DO NOT use the aerial platform
as a crane. It is prohibited.
• DO NOT sit, stand or climb on
the guardrails. It is prohibited.
• DO NOT climb on scissor arm
assembly. It is prohibited.
• AVOID overhead obstructions.
Be aware of overhead
obstructions or other possible
hazards around aerial platform
when lifting or driving.
• AVOID crushing hazards. Be
aware of crushing hazards
when lifting or driving. Keep
all body parts inside the aerial
platform.
• DO NOT raise the aerial
platform while the aerial
platform is on a truck, fork lift
or other device or vehicle.
• DO NOT lower the platform
unless the area below is clear
of personnel and obstructions.
• ENSURE that there are no
personnel or obstructions in
the path of travel, including
blind spots.
• BE AWARE of blind spots when operating the
aerial platform.
• DO NOT use with improperly
inflated/damaged tires or
wheels. Refer to Section 2:
Wheel/Tire Assembly.
• ENSURE ALL tires are in
good condition and bolts are
properly tightened.
• DO NOT alter or disable
limit switches or other safety
devices.

Safety Precautions (Continued)
Know and understand the safety precautions before going on to next section.
• DO NOT use the aerial platform
without guardrails, locking pins
and the entry gate(s) in place.
• DO NOT use under influence
of alcohol or drugs.
• STUNT driving and horseplay are prohibited.

Safety Rules Section 1 - About Your Aerial Platform

Safety Precautions (Continued)
Know and understand the safety precautions before going on to next section.
Fall Protection
As per the ANSI A92.6-2006 standard, “The
guardrail system of the aerial platform provides
fall protection. If occupant(s) of the platform are
required to wear personal fall protection equipment
(PFPE), occupants shall comply with instructions
provided by the aerial platform manufacturer
(remanufacturer) regarding anchorage(s).”
If additional fall protection is required, by an
employer or the authority having jurisdiction,
Skyjack recommends the use of a fall restraint
system to keep an occupant within the confines
of the platform, and thus not expose the occupant
to any fall hazard requiring a fall arrest.
All personal fall protection equipment must
comply with applicable governmental regulations
and must be inspected and used in accordance
with the manufacturer’s recommendations.
All personal fall protection equipment must be
attached only to approved anchorage points
within the platform of the aerial platform.
WARNING
Entering and exiting the aerial platform
should only be done using the three
points of contact.
• Use only equipped access openings.
• Enter and exit only when the aerial platform
is in the fully retracted position.
• Do use three points of contact to enter and exit
the platform. Enter and exit the platform from
the ground only. Face the aerial platform when
entering or exiting the platform.
• Three points of contact means that two hands and
one foot or one hand and two feet are in contact
with the aerial platform or the ground at all times
during entering and exiting.
WARNING
An operator should not use any aerial
platform that:
• does not appear to be working
properly.
• has been damaged or appears to have
worn or missing parts.
• has alterations or modifications not
approved by the manufacturer.
• has safety devices which have been
altered or disabled.
• has been tagged or locked out for
non-use or repair.
Failure to avoid these hazards could
result in death or serious injury.
Jobsite Inspection
• Do not use in hazardous locations (see NFPA
505).
• Perform a thorough jobsite inspection prior to
operating the aerial platform, to identify potential
hazards in your work area.
• Be aware of moving equipment in the area. Take
appropriate actions to avoid collision.
