2.2-10 Overload Warning System
The aerial platform is equipped with a load sensing
system (refer to Table 2-3 for maximum platform ca-
pacities).
When 90% of the rated load is reached:
The red power indicator light of the operator’s
control box flashes.
When the rated load is reached:
An audible alarm sounds for approximately 2
seconds, 5 times per minute.
When the rated load is exceeded:
The flashing light and audible alarm continue and
all electrically controlled machine movement
functions stop. To resume normal operation,
remove the overload from the platform.
If the machine during the operation comes in
contact with an overhead obstruction:
The platform could become overloaded and all
functions would stop. Release of the platform from
this situation can only be effected by use of the
emergency lowering system. Refer to Section 2.8.
Note
After reaching full extension and upon lowering, the
machine could stop and take an overload reading.
Return the proportional controller to the neutral
position, and release the enable trigger switch. If the
machine is overloaded, the flashing light and audible
alarm continue and all electrically controlled machine
movement functions stop. To resume normal
operation, remove the overload from the platform.

Use this ring as an attachment point for safety belt/
harness tethers. DO NOT attach belts/harnesses to any
other point on the platform. DO NOT use this ring to lift,
anchor, secure or support the platform or any other
