Snorkel S3246E - Manual (Page 7)

Special Limitations
S2646E/S3246E – 1370385 5
Special Limitations
Travel with the platform raised is limited to creep speed
range. Elevating the platform is limited to firm, level
surfaces only.
Danger
The elevating function shall ONLY be used when the
work platform is level and on a firm surface.
The work platform is NOT intended to be driven over
uneven, rough, or soft terrain.
Platform Capacity
Two people and tools may occupy the platform when the
machine is indoors only. The maximum platform capacity
for the aerial platform is stated in the “Specifications” on
pages 20-21.
Danger
DO NOT exceed the maximum platform capacity or
the platform occupancy limits for this machine.
Manual Force
Manual force is the force applied by the occupants to
objects such as walls or other structures outside the
work platform.
S2646E Maximum Manual Force
In windy conditions up to 12.5 m/s (28 mph) the maximum
allowable manual force is limited to 222 N (50 lbs).
In zero wind conditions the maximum allowable manual
force is limited to 666 N (150 lbs).
S3246E Maximum Manual Force
In windy conditions up to 12.5 m/s (28 mph) the maximum
allowable manual force is limited to 222 N (50 lbs).
In zero wind conditions the maximum allowable manual
force is limited to 467 N (105 lbs).
Danger
DO NOT exceed the maximum amount of manual
force for this machine.
Drive/Lift Pothole Protector Interlock
The aerial platform drive and lift functions are interlocked
through a limit switch that senses whether or not the pot-
hole protection linkage is locked into position. The drive/lift
pothole interlock operates when the platform is elevated
approximately 2.1 to 2.4 m (7 to 8 feet).
If an obstruction under the skids, or some other impair-
ment prevents the skids from locking into position, the
drive and lift functions will not operate and an alarm will
sound.
Lower the platform and remove the obstruction when the
drive/lift pothole protector interlock alarm sounds.
Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are interlocked
through a level sensor system. The drive/lift level sensor
interlock operates when the platform is elevated approxi-
mately 2.1 to 2.4 m (7 to 8 feet).
If the chassis is tilted more than 2 degrees side-to-side
or more than 4 degrees front-to-rear, the drive and lift
functions will not operate and an alarm will sound.
Lower the platform and drive to a level surface when the
drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection
and does not justify operating on anything other than firm,
flat, level surfaces.
Lowering Alarm
When the joystick is moved out of neutral to lower the
platform, the alarm emits a loud beeping sound to warn
personnel in the work area to stand clear.
Danger
Pinch points exist on the scissors structure. Death
or serious injury will result if the scissors structure
lowers onto personnel within the scissors arms or
under the raised platform. Stand clear while raising
and lowering the platform.
Be careful when lowering the platform. Keep hands and
fingers away from the scissors structures components.
Lowering Interrupt
When the platform is lowered to about 1.5 m (5′) lower-
ing stops. The platform will not lower for five seconds
regardless of the control position to allow personnel to
clear the area of the scissors before the platform com-
pletely lowers.
Center the control in neutral to reset the lowering function,
then continue to lower the platform.
Overload Protection
When the load in the platform is near or at rated capac-
ity, an alarm will sound and the red light on the upper
controls will flash.
The alarm and light warn the operator that the platform
is close to becoming overloaded. All functions remain
fully operational.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not exceed the capacity values indicated
on the platform rating placard.
If the platform is fully lowered and is overloaded, when
it is elevated just past 1.8 m (6′), a control module will
stop the lift and drive functions and the alarm will sound
and the warning light will flash. The platform can still be
lowered to remove the excess load.
