Purpose of Equipment
The SKYJACK Rough Terrain’s mid and full size aerial platforms are designed to transport and raise personnel,
tools and materials to overhead work areas.
Use of Equipment
The aerial platform is a highly maneuverable, mobile work station. Work platform elevation and elevated driving
must only be done on a firm level surface. It can be driven over uneven terrain only when the platform is fully
lowered.
Manual
The operating manual is considered a fundamental part of the aerial platform. 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 aerial platform 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 aerial platform. Compare the labels on the
aerial platform 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 SJRT Series aerial 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.

Safety Rules Section 1 - About Your Aerial Platform
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

December 2007 Page 7
Section 1 - About Your Aerial Platform Safety Rules
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.”
As per AS 2550.1-2002
Elevating Work Platforms must remain 6.4 m from electrical distribution lines up to 133 kV and 8 m from transmission
lines greater than 133 kV. State regulations may take precedence over these approach distances.
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 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 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,

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 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
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 4-3.

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.
