PRECAUTIONS FOR BLADE OPERATION

This blade is designed as a light service attachment for the
hydraulic excavator. Please keep the following points in mind:
1. This blade is designed to be used for dozing work only. Do
not attempt to dig deeply with the blade. Doing so will
damage not only the blade but the undercarriage as well.
2. Do not apply intensive or uneven loads. Never apply high-
speed impact to the blade by running the machine into a
load.
3. Jacking up the machine with this blade, the surface be-
neath the blade comes under high pressure, increasing
the risk of surface collapse.
Always be sure that the surface is strong enough to sup-
port the weight of the machine during operation.
Avoid dangerously uneven distribution of weight on the
blade by maintaining even contact between the blade
and the ground.
4. Never use this blade as an outrigger.
5. Avoid contact between the bucket and the blade while
digging.
