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 modications from the original design are strictly forbidden without written permission from SKYJACK.

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 A92.5-2006 8.10(7)
“The operator shall perform only the work for which he or she is qualied, 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 qualied to do so. Operators shall
maintain the appropriate minimum approach distance (MAD) from energized power lines and parts covered by
CFR 1910.333 (c).”
Unqualied 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 B354.4-02
“The operator shall maintain the minimum safe approach distance (MSAD) from energized conductors at all times
in accordance with the authority having jurisdiction.”
Refer to CFR 1910.333 or the authority having jurisdiction.
DO NOT USE AERIAL PLATFORM AS A GROUND FOR WELDING.
DO NOT OPERATE 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
aerial platform .
• AVOID entanglement with
ropes, cords or hoses.
• AVOID falling. Stay within the
boundaries of the guardrails.
Maintain rm footing on the
platform oor at all times while
working thereon.
• ENSURE all occupants wear
personal fall protection equipment.
• DO NOT raise the aerial
platform or operate elevated in
windy or gusty conditions that
exceed the limits specied 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 aerial
platform stability. Avoid tenting.
• DO NOT elevate the aerial platform if it is not on
a rm, level surface.
• DO NOT drive elevated near
depressions or holes of any
type, loading docks, debris,
drop-offs and surfaces that
may affect the stability of the
aerial platform.
• DO NOT elevate or drive
elevated on a slope. Elevated
driving must be done on a rm,
level surface.
• 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 rm, level
surface, the aerial platform can
be elevated. After elevation,
the drive function must not be
activated.
• DO NOT drive elevated on a
soft or uneven surface.
• DO NOT ascend or descend a
grade steeper than 45% (4WD).
Boom elevated driving must
only be done on rm, level
surfaces.

Safety Precautions (Continued)
Know and understand the safety precautions before going on to next section.
• 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 horizontal
(manual) force on aerial
platform that exceeds the limits
specied in Table 4.4.
• DO NOT use the aerial platform
as a crane. It is prohibited.
• DO NOT climb on boom arm
assembly. It is prohibited.
• DO NOT sit, stand or climb on
the guardrails. 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.
• BE AWARE of blind spots when
operating the aerial platform.
• ENSURE that there are no
personnel or obstructions in
the path of travel, including
blind spots.
• DO NOT lower the platform
unless the area below is clear
of personnel and obstructions.
• DO NOT use boom to push,
pull other objects or to lift the
chassis.
• DO NOT raise the aerial
platform while it is on a truck,
forklift or other device or vehicle.
• STUNT driving and horseplay are prohibited.
• DO NOT use with improperly
inated/damaged tires or
wheels. Refer to Section 2:
Wheel/Tire Assembly.
• 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.
Fall Protection
WARNING
Failure to wear personal fall protection
equipment may result in death or serious
injury.
All occupants of this aerial platform must wear
personal fall protection equipment.
As per the ANSI A92.5-2006 standard, “Principal
fall protection is provided by the guardrail system.
The user shall direct and monitor the operator to
ensure that all components of the guardrail system
are in place. The user shall direct and monitor
the occupants of the work platform to ensure that
they wear a personal fall arrest system to protect
against the potential effects of ejection or a fall
restraint system to prevent a free fall.”
Fall restraint and fall arrest systems are dened
within the ANSI A92.5 Manual of Responsibilities
shipped with this aerial platform.
Skyjack recommends the use of a fall restraint
system to keep an occupant within the connes
of the platform, and thus not expose the occupant
to any fall hazard requiring a fall arrest.
CSA B354.4-02 requires the use of a fall arrest
system, therefore Canadian users must use
personal fall arrest protection as opposed to fall
restraint.
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 modications 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.
