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.

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.”
DO NOT USE THE AERIAL PLATFORM AS A GROUND FOR WELDING.
DO NOT OPERATE THE AERIAL PLATFORM DURING LIGHTNING OR STORMS.

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 job site.
• TURNmainpowerdisconnect switch “ ”offwhen
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
in windy or gusty conditions.
• DO NOT increase the lateral
surface area of the platform.
Increasing the area exposed
to the wind will decrease aerial
platform stability.
• DO NOT drive or 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 and
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 level firm surface,
the aerial platform can be
elevated. After elevation, the
drive function must not be
activated.
• Elevated driving must
only be done on a firm level
surface.
• DO NOT ascend or descend
a grade when elevated. When
fully lowered, ascending or
descending grades up to
maximum rated inclines listed
in Table 2.3.

Section 1 - About Your Aerial Platform Safety Rules
Safety Precautions (Continued)
Know and understand the safety precautions before going on to next section.
• 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
