Drill steel
CAUTION Hot working tool
The tip of the working tool can become hot and
sharp when used. Touching it can lead to burns
and cuts.
►
Never touch a hot or sharp working tool.
►
Wait until the working 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.
WARNING Vibration hazard
Using inserted tools that do not fulfil the criteria
mentioned below, will result in a longer time to
complete a task, and may result in higher levels of
vibration exposure. A worn tool will also cause
increased working time.
►
Make sure that the inserted tool is well-
maintained, not worn out and of the proper size.
►
Always use a sharp tool in order to work
efficiently.
WARNING Ejected insertion tool
If the tool retainer on the machine is not in a locked
position, the inserted tool can be ejected with
force, which can cause personal injury.
►
Before changing the insertion tool, stop the
machine, switch off the compressed air supply
and bleed the machine by activating the start
and stop device.
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.
Fitting the drill steel
Whenever fitting the drill steel the following
instructions must be observed:
1. Push the retainer outwards in the direction of
the arrow, until the front portion of the retainer
is able to accommodate the drill steel collar.
2. Insert the drill steel in the chuck.
3. When the drill bottoms, push back the retainer
to lock it.
