SAFETY
When carrying out demolition work, do not carry out demoli-
tion above your head. There is a hazard of broken parts fall-
ing or of the building collapsing and causing serious injury
or property damage.
Do not use the impact force of the work equipment for
breaking work. There is a hazard of damage to the work
equipment or a hazard of serious personal injury being
caused by flying pieces of broken materials or the machine
tipped over due to reaction from the impact.
Generally speaking, the machine is more liable to overturn
when the work equipment is at the side than when it is at the
front or rear.
When using a breaker or other heavy work equipment, there is a hazard of the machine losing its balance and
tipping over. When operating on flat ground as well as on slopes.
Do not suddenly lower, swing, or stop the work equipment.
Do not suddenly extend or retract the boom cylinder. There is a hazard that impact will cause the machine to
tip over.
Do not pass the bucket over the head of other workers or over the operator's seat of dump trucks or other haul-
ing equipment. The load may spill or the bucket may hit the dump truck and cause serious injury or property
damage.

OPERATIONS ON SNOW

Snow-covered or frozen surfaces are slippery, so be extremely careful when traveling or operating the
machine, and do not operate the levers suddenly. Even a slight slope may cause the machine to slip, so be par-
ticularly careful when working on slopes.
With frozen ground surfaces, the ground becomes soft when the temperature rises, and this may cause the
machine to tip over.
If the machine enters deep snow, there is a hazard that it may tip over or become buried in the snow. Be careful
not to leave the road shoulder or to get trapped in a snow drift.
When clearing snow, the road shoulder and objects placed beside the road are buried in the snow and cannot
be seen. There is a hazard of the machine tipping over or hitting covered objects, so always carry out opera-
tions carefully.

PARKING MACHINE

Park the machine on firm, level ground.
Select a place where there is no hazard of falling rocks or
landslides, or of flooding if the land is low.
Lower the work equipment completely to the ground.
