Figure 1 – Beaufort Scale
If the platform is elevated just past 1.8 m (6′) and material
is added to the platform overloading it, a control module
will stop the lift, drive and lower functions and the alarm
will sound and the warning light will flash. In this case,
remove the load in excess of rated capacity and cycle
the emergency stop button at the upper controls to return
to normal operation.
Beaufort Scale
Never operate the machine when wind speeds exceed
12.5 m/s (28 mph) [Beaufort scale 6]. Refer to Figure 1.
