4.2 Operations to be avoided
If you insist on the same spot for a long time, the drill can swell up, the tool can seize
and the oil can become overheated.
Avoid that the hammer delivers blank firings. They
cause early weariness and chippings to the retainer
pin for tool and to the tool itself, which scraps can
provoke serious damages. Moreover, due to these
blank firings, the tool will break very soon.
The tool cannot be used as a lever to move rocks or
debris: this operation can cause the seizing or
breaking of the tool, mainly if it is carried out while the
hammer is working.
Do not remove big rocks with the help of the hammer
frame: some parts can unweld and the plate can
warp.
Do not hammer on the same spot for more than thirty
seconds. In case of a very hard surface, it is
necessary to change position very often until you find
a softer ground.
Never forget to pre-heat the oil before beginning
to work: particularly in case of low outdoor
temperatures, it is a good practice to operate the
translation control and those of the central piston
of the excavator boom to the end of the stroke,
until the oil reaches a temperature of 25-30°C.
