SAFETY
q Do not pass the bucket over the heads of other workers or over the operator's seat of dump trucks or other
hauling equipment. There is danger that the load may spill or the bucket may hit the dump truck and cause
serious personal injury or death.
q When working on or from the top of buildings or other structures, check the strength and the structure before
starting operations. There is a hazard of the building collapsing and causing serious injury or damage.
q 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 of the machine.
Be extremely careful when swinging the work equipment from the front or rear to the side of machine while it is
applied a load. There is danger that the machine may turn over.
q When using a breaker or other heavy work equipment, there is a hazard of the machine losing its balance and
turning over. When operating on flat ground as well as on slopes, observe the following.
Q Do not suddenly lower, swing, or stop the work equipment.
Q Do not suddenly extend or retract the boom cylinder. There is a hazard that impact will cause the machine
to turn over.
q In the operation using the fork or grapple, do not attempt to
pick up an object with their tips.
There is a danger of damage to the machine or personal
injury, as the picked - up object can easily slip off.
OPERATIONS ON SNOW
q 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
particularly careful when working on slopes.
q With frozen ground surfaces, the ground becomes soft when the temperature rises, and this may cause the
machine to tip over or make it impossible for the machine to escape.
q 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.
q 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
operations carefully.
PARKING MACHINE
q Park the machine on firm, level ground.
q Select a place where there is no hazard of landslides,
falling rocks, or flooding.
q Lower the work equipment and blade completely to the
ground.
