Safety
Protecting Cabin from Falling Object
(Optional)
In a work site where falling objects or flying objects are
expected, be sure to install adequate protective devices for
covering the cabin.
When using a breaker, be sure to install the front window
protection guard (Figure 25).
In a work site where falling rocks can cause damage and
possibly crush personnel, or in a mining operation, be sure to
install the falling object protective structure (Figure 26).
Be sure to install any other additional protective structures
required for work site conditions.
When the falling object protective structure is installed, and the
front window needs to be cleaned, loosen the bolts marked with
an arrow. Be sure to tighten bolts when done.
Operate Carefully on Snow, Ice and in Very
Cold Temperatures
In icy cold weather avoid sudden travel movements and stay
away from even slight slopes. The machine could skid off to one
side very easily.
Snow accumulation could hide or obscure potential hazards.
Use care while operating or while using the machine to clear
snow.
Warming up the engine for a short period may be necessary, to
avoid operating with sluggish or reduced working capacity. The
jolting shocks and impact loads caused by bumping or
bottoming the boom or attachment are more likely to cause
severe stress in very cold temperatures. Reducing work cycle
rate and work load may be necessary.
When the temperature rises, frozen road surfaces become soft,
so the machine travel becomes unstable.
In cold weather, do not touch metal surfaces with your bare
hands. If you touch a metal surface in extremely cold weather,
your skin may freeze to the metal surface.
