SAFETY
COLLISION HAZARDS
• Pay attention to the field of sight
and the presence of blind spots
when moving or operating the
machine.
• The non-staff must maintain a
minimum of 2m (6.6ft) distance
from the machine while it is
travelling or swinging.
• When the work platform of a
moving machine is approx2m
(6.6ft) away from the
obstructions, use the boom lift
function (rather than the drive
function) to get close to the
obstructions.
• Switch to the low speed gear
before parking the machine that
drives at high speed.
• Do not use the high speed gear
when the machine is driving
reverse or in restricted or
enclosed work area.
• Check the work area to avoid
ground and overhead
obstructions or other possible
risks.
• Be sure to exercise caution when
using the platform and ground
controls. Color-marked
directional arrows show the
function of travel, lift and
steering.
• Users must comply with user,
workplace and government rules
regarding the use of personal
protective equipment (hard hats,
safety belts and gloves, etc.).
• Place the machine on level
ground or in a secured position
before releasing the brakes.
• Only lower the platform when
there are no people or
obstructions in the area beneath
it.
• When the machine is conducting
aerial work, warn the staff/non-
staff not to work, stand or walk
under the raised boom or
platform.
• Limit the speed of travel
according to ground conditions,
crowding, gradients, the presence
COLLISION HAZARDS
and location of personnel and any
other factors that may cause
collisions.
• Do not operate the machine on
any crane or overhead traveling
device unless the crane control is
locked or precautions have been
taken to prevent any potential
collision.
• Keep the machine away from any
stationary objects (buildings etc.)
or mobile objects (vehicles,
cranes etc.).
• Never operate a machine
dangerously or for fun.
CRUSH HAZARDS
A potential crush hazard exists during movement of the
machine. Always keep body parts and clothing a safe
distance from the machine during machine operation.
CRUSH HAZARDS
• Do not place your hands and arms
where they may become crushed
or trapped.
• Do not work under the platform or
the boom when the boom is not
protected by a crane.
• Maintain good judgment and
planning when using the
controller on the ground to
operate the machine. Maintain
proper distance between operator,
machine and fixed object.
