3.20 BLADE OPERATION
3.20.1 PRECAUTIONS WHEN USING THE BLADE
[BASIC POSTURE WHEN WORKING WITH THE BLADE]
• When hoisting load, be sure to conduct with the blade raised off the ground. There is a risk of
a serious accident occurring, such as damage to or overturning of the machine.
• Do not remove extraneous material with the blade while hoisting a load. There is a risk of a
serious accident occurring, such as damage or overturning of the machine.
• When removing extraneous material, put the machine
into the following basic posture.
• Place the sprocket (A) in the rear, and face the
operator’s seat towards the front.
• Fully retract the boom, and stow the hook.
• Adjust the boom angle to within the range of “fully
lowered to 35 degrees”.
Raising the boom too much can cause the machine to
overturn and cause serious accidents.
• Removing extraneous material with the machine in a
posture different from the basic posture can cause the
machine to overturn, or the wires to be damaged, and
cause serious accidents.
[CAUTIONS WHEN REMOVING EXTRANEOUS MATERIAL]
• The tip of the crane when the boom is in “fully
lowered state”, is “1540 mm” longer than the tip of the
blade. Confirm that there are no obstacles in front
before starting the work. Failure to check may result
in collisions with obstacles and cause serious
accidents.
• When work is finished or when transporting the
machine, be sure to rest the blade on the ground.
When the blade cylinder drops naturally, or the
hydraulic mechanism is broken, the blade may fall
and cause serious accidents.
• Do not put the machine in reverse while the blade is
resting on the ground.
The hydraulic hose may become damaged, making
the blade unusable.
• Do not let the blade collide with fixed objects such as
rocks.
The blade or cylinder will become damaged quickly.
