Precautions for Blade Operation
This blade is designed as a light service attachment of
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. Do-
ing so will damage not only the blade but the under-
carriage as well.
2. Do not apply intensive or uneven loads to the blade.
Never apply high-speed impact shock to the blade by
running the machine into a load.
3. When jacking up the machine with this blade, the sur-
face 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 during operation.
Avoid dangerous uneven distribution of weight to the
blade by maintaining even contact between the blade
and the ground.
4. While digging, take care not to allow the bucket to
come into contact with the blade.
