PRECAUTIONS FOR BLADE OPERATION
This blade is designed as a light service attachment of
the hydraulic excavator. Please keep the following
points in mind:
•
This blade is designed for bull dozing work only.
Do not attempt to dig deeply with the blade. Doing so
may damage not only the blade but the undercarriage
as well.
•
Do not apply concentrated or uneven loads to the
blade. Never allow the blade to forcefully collide with a
load by running the machine into the load. Failure to
do so may result in damage to the blade and the
undercarriage.
•
When jacking up the machine with this blade, the
surface beneath the blade comes under high pressure,
increasing the risk of surface collapse. Always be sure
that the surface is strong enough to support the weight
of the machine before jacking up the machine. Avoid
dangerous uneven distribution of weight to the blade
by maintaining even contact between the blade and
the ground.
•
While digging with the blade positioned in the front of
the machine, take care not to allow the bucket to come
into contact with the blade.
•
When digging, take care not to allow the boom
cylinder to come in contact with the blade.
