important information about the condition of the drill
and about the way it is used and maintained.

microscopic fissures on the

Storage

Always oil the rock drill well, before you put it into
●
storage.
Always store the machine in a clean and dry place.
●
● Make sure that no foreign matter enters the
machine.
Protect the chuck using the plastic plug provided
●
with the machine. Alternatively, use a wooden plug
or a clean piece of cotton waste.
In the case of long-term storage, pour a quantity
●
of oil directly into the rock-drill's air intake and then
turn on the air briefly. This will protect the machine
from corrosion.
