4 Use of the hammer
The operator must follow the manufacturer’s instructions.
It is forbidden to use the hammer without the retainer pin for tool.
Use only tools authorised by the manufacturer.
The hammer must be in an open area so that, when it begins to hit, the tool is with no doubt
pressed against the surface of the material.
Engine speed
During the inspection of the hammer, the installer determinates the exact number of revs of
the excavator engine to which corresponds the appropriate oil flow rate for the hammer.
It is absolutely necessary that the operator respects these datas.
Working with a higher or lower number of revs can cause serious damages to the
hammer.
4.1 Instruction for use
The hammer can work in all the positions allowed by the joints of the excavator boom, as
long as it is always pressed perpendicularly against the surface of the material to be
demolished.
The operator must release the correct load pressure on the hydraulic pipe line to the
hammer: if it is too low, it retains a part of the energy which will be released to the excavator
boom that will eventually undergo dangerous vibrations and shakings.
If it is too powerful instead, it can endanger the structure of the hammer, of the metal plate
and the tool.
The correct position must be kept during the whole phase of feed of the
tool, operating on the controls of the bucket and the forearm.
