Snorkel A46JRT - Manual (Page 7)

Special Limitations
A46JRT – 0260228 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.
Platform Capacity
Two people and tools may occupy the platform. The maxi-
mum platform capacity for the aerial platform is stated in
the “Specifications” on page 23.
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.
The maximum allowable manual force is limited to 200 N
(45 lb) of force per occupant, with a maximum of 400 N
(90 lb) for two occupants.
Danger
DO NOT exceed the maximum amount of manual
force for this machine.
Platform Overload Sensing System
All functions are stopped from the upper and lower con-
trols, when the platform overload limit is exceeded. The
horn will sound intermittently and the platform overload
light will blink until the excess load is removed from the
platform. At that time, the machine functions are again
operational.
Caution
The emergency power system is for emergency low-
ering and stowing only. The length of time the pump
can be operated depends on the capacity of the bat-
tery. Do not use this system for normal operation.
If the platform overload sensing system is tripped while
operating the machine, the emergency power system may
still be used for emergency machine operation.
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.
The overload sensing system is not active when the
machine is being driven with the booms in the stowed
position. This allows the machine to be driven without
the system sensing an overload due to rough ground
conditions.
Beaufort Scale
Never operate the machine when wind speeds exceed
12.5 m/s (28 mph) [Beaufort scale 6]. Refer to Figure 1.

or swamps.
