IMPORTANT SAFETY RULES
which is crucial for maintaining
the stability of the machine.
• Do not operate the machine in
wind speeds exceeding 12.5 m/s
(28 mph). Please check the Beau-
fort wind force scale in Page 10,
Table 2-2 . Factors that affect wind
speed include: height of the plat-
form, surrounding terrain, and lo-
cal weather conditions, such as
wind speed at height, which may
be much higher than at ground
level.
• Wind speeds can change at any
time. Always consider the
impending weather conditions,
the time needed to lower the plat-
form, and methods to monitor cur-
rent and potential wind
conditions.
• When operating the machine out-
doors, do not carry items with a
large surface area on the platform,
do not cover the surface of the
platform or load, and never use
additional items that increase the
surface area of the platform or
load. Adding such additional
items will increase the area of the
machine exposed to wind. In-
creasing the windward area will
lead to reduced machine stability.

If the wind speed exceeds 12.5 m/s (28 mph) after the platform has been raised, the platform should be
retracted immediately, then all power sources should be disconnected, and the machine should be
stopped.
