Special Limitations

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 maximum 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 controls, 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.

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 accident. 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.

Caution

The emergency power system is for emergency lowering and stowing only. The length of time the pump can be operated depends on the capacity of the battery. Do not use this system for normal operation.
