2.1 Electrocution hazards
The MEWP is not electrically insulated and does not
provide protection from contact with or proximity to
energized electrical conductors. Follow Section 2.1-1
for the minimum distance to keep between all parts
of the MEWP, occupants, or tools, and the electrical
conductors. Consider MEWP movement and electrical
line sway in minimum distance calculation.
2.1-1 Minimum distance from electrical
conductors
Voltage Range
(Phase to phase)
Minimum Distance from
Electrical Conductors
(Meters)
Without Spotter With Spotter
Up to and including
133KV 6.4 3
Greater than 133KV 10 8
DANGER
Electrocution hazard. Keep all parts of the MEWP,
occupants, or tools a safe distance away from
power lines, electrical power sources, or energized
sources. If you do not obey, there is a risk of death
or serious injury.
Keep a minimum safe distance
from sources of high-voltage
power.

Section 2 – General Safety Precautions Safety instructions
2.2 Safety instructions
WARNING
DO NOT operate this MEWP without proper
authorization and training. Failure to avoid this
hazard could result in death or serious injury.
WARNING
DO NOT operate this MEWP in enclosed areas
without adequate ventilation for exhaust gas and
fumes. Failure to follow this warning could cause
death or serious injury.
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/provincial or territorial, and
local rules which apply to your MEWP and worksite.
MAKE SURE all the safety and instructional labels
are correctly attached on the MEWP in the correct
location. Clean or replace labels that you cannot read.
DISCONNECT and lock out main power disconnect
on the left side of the MEWP when leaving the MEWP
unattended to prevent unauthorized use.
DO NOT wear jewelry or loose
clothing that could become
caught or entangled.
DO NOT allow the
entanglement of ropes, cables
or hoses with the MEWP,
adjacent structures or objects.
Prevent falling from the
platform. Always keep a rm
footing on the platform oor
when working thereon. Do not
climb on the toe-board, mid-rail,
or top-rail. Do not use planks,
ladders, or any other devices
on the platform for achieving
additional height or reach.
MAKE SURE all occupants wear personal fall
protection equipment.
DO NOT raise the platform or
operate elevated in windy or
gusty conditions that exceed
the limits specied in
Section 7.7.
DO NOT increase the surface
area of the platform or carry
large surface area items when
exposed to wind. Increasing the
area exposed to the wind will
decrease the MEWP stability.
MAKE SURE the ground condition assessment
considers the subsurface voids such as cellars,
basements, culverts, and pipes.
DO NOT elevate or drive
elevated on a slope. Elevated
driving must be done on a rm,
level surface.

drop-offs or surfaces that may
affect the stability of the 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
have contact with a rm, level
surface, the platform can be
raised. After elevation, the drive
function must not be activated.
DO NOT drive elevated on a
soft or uneven surface.
DO NOT raise the platform if it
is not on a rm, level surface.
DO NOT ascend or descend
grades greater than the
maximum inclines listed in
Section 7.4. Ascending or
descending slopes must only
be done when fully lowered.
DO NOT operate a MEWP that
has ladders, scaffolding, or
other devices on it to increase
the platform size or work height.
DO NOT exceed the maximum
side force on the platform
capacity label when elevated
(refer to Section 7.7).
DO NOT use the MEWP as a
crane.
DO NOT step on the boom
arm assembly.
DO NOT sit, stand, or climb on
the guardrails.
DO NOT collide or crush.
Be aware of obstructions,
personnel, or other possible
hazards around the MEWP
when elevating, lowering, or
driving. Keep all body parts
inside the platform when
elevating or driving. Be aware of
blind spots when operating the
MEWP.

Fall-protection Section 2 – General Safety Precautions
2.3 Fall-protection
The guardrail system is the primary fall-protection
system of the MEWP platform.
All occupants of this machine must wear personal fall-
protection equipment (PFPE) at all times.
Skyjack recommends the use of a full body harness
with a lanyard. PFPE must be attached only to
approved fall-protection anchorage points in the
platform.
All PFPE must be compliant with applicable
government rules and must be inspected as per the
manufacturer’s recommendation.
WARNING
Fall hazard.
▪Only enter and exit the MEWP using the three
points of contact principle.
▪Only use the equipped access openings.
▪Only enter and exit the MEWP when the
platform is fully lowered.
▪Face the MEWP when entering or exiting the
platform.
Failure to follow these instructions could result in
death or serious injury.
Enter or exit the platform from the ground only. Use
the three points of contact principle, which is when
two hands and one foot, or one hand and two feet are
in contact with the MEWP or the ground at all times.
Face the MEWP when entering or exiting the platform.
2.4 Worksite inspection
Make sure the operating environment, ambient
temperature, Electromagnetic Compatibility (EMC),
and Hazardous Location Rating (locations with
potentially ammable gases, explosive gases or
particles) are appropriate for the MEWP specications
(refer to Section 7.5).
Be sure to follow all national, state/provincial/territorial,
and local rules that relate to operating the MEWP.
Perform a full worksite inspection before operating the
MEWP. Identify potential hazards in the area.
Be aware of moving equipment in the area. Take the
necessary precautions to prevent collisions.
It is the responsibility of the operator to perform a
worksite inspection and avoid/address the following
hazards:
▪Holes or drop-offs
▪Slopes
▪Ditches or soft lls
▪Floor obstructions, bumps, or debris
▪Overhead obstructions
▪Electrical conductors
▪Hazardous locations
▪Inadequate surface support to withstand all load
forces imposed by the MEWP (refer to
Section 7.8)
▪Wind and weather conditions
▪Presence of personnel
▪Other mobile equipment
▪Trafc hazards
▪Equipment that could move and collide with the
MEWP, such as overhead cranes
▪Other possible unsafe conditions.
