Safety and operating instructions

Before fitting the insertion tool

Check that the tool shank is of the correct size and
length for the chuck used. The shank must be clean
and the tool must be in good condition. Shanks which
are chipped, rounded, out of square or too hard on
the striking end will operate inefficiently and cause
premature piston failure.
Inspect the drill steel:
A dull drill steel will slow down the drilling speed and
overstrain the drill mechanism. When changing drill
steel make sure that the new one is the correct size
to follow your previous bore.
Before drilling, check that the flushing hole in the drill
steel is not blocked.
CAUTION Hot insertion tool
The tip of the insertion tool can become hot and
sharp when used. Touching it can lead to burns and
cuts.
Never touch a hot or sharp insertion tool.
►
► Wait until the insertion tool has cooled down before
carrying out maintenance work.
NOTICE Never cool a hot insertion tool in water, it
can result in brittleness and early failure.
