SAFETY PRECAUTIONS
Know and understand the safety precautions before going on to next section.
WARNING
Failure to heed the following safety pre-
cautions could result in tip over, falling,
crushing, or other hazards leading to
death or serious injury.
• KNOW all national, state/provincial and local
rules which apply to your MACHINE and JOB-
SITE.
• TURN the main power disconnect switch OFF
when leaving the machine 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 plat-
form in windy or gusty condi-
tions.
• DO NOT increase the lateral
surface area of the platform.
Increasing the area exposed to
the wind will decrease machine
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 sta-
bility of the aerial platform.
• If operation in areas with
holes or drop-offs is abso-
lutely necessary,elevated
driving shall not be allowed.
Position the machine horizon-
tally 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. Af-
ter elevation, the drive function
must not be activated.
• Elevated driving must only
be done on a firm level sur-
face.
• DO NOT ascend or descend
a grade when elevated. When
fully lowered, ascending or de-
scending, only grades up to
rated maximum listed in Table
2-1a and Table 2-1b are permis-
sible.

holding the weight of the aerial platform including
the rated load, e.g. covers, drains, and trenches.
• DO NOT operate an aerial plat-
form that has ladders, scaffold-
ing 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
the guardrails. It is prohibited.
• DO NOT climb on scissor arm
assembly. It is prohibited.
• BE AWARE of overhead ob-
structions or other possible
hazards around the aerial plat-
form when driving or lifting.
• DO NOT raise the aerial plat-
form while the machine is on a
truck, fork lift or other device or
vehicle.
• BE AWARE of crushing haz-
ards. Keep all body parts in-
side platform guardrail.
• DO NOT lower the platform
unless the area below is clear
of personnel and obstruc-
tions.
• ENSURE that there are no personnel or obstruc-
tions in the path of travel, including blind spots.
• BE AWARE of blind spots when operating the
aerial platform.
• STUNT driving and horseplay are prohibited.
• ENSURE ALL tires are in good condition and lug
nuts are properly tightened.
• DO NOT alter or disable limit switches or other
safety devices.
• DO NOT use the aerial platform without guard-

sensing)
• DO NOT attempt to free a snagged platform with
lower controls until personnel are removed from
the platform.
• DO NOT position the aerial platform against an-
other object to steady the platform.
WARNING
Entering and exiting the aerial platform
should only be done using the three
points of contact system.
• Use only equipped access openings 
and ladders.
• 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
