Original Instructions
5.7.1 Before fitting the drill steel
Check that the tool shank is of the correct size and
length for the chuck used. The tool shank must be clean
and the drill steel must be in good condition. Tool 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 of the
correct size to follow the previous bore.
Before drilling, check that the flushing hole in the drill
steel is not blocked.
WARNING Ejected drill steel
If the tool retainer on the machine is not in a locked posi-
tion, the drill steel can be ejected with force, which can
cause personal injury.
u Never start the machine while changing the drill
steel.
u Before changing the drill steel or accessories, stop
the machine and turn off the power source.
u Never point the drill steel at yourself or anyone else.
u
Make sure that the drill steel is fully inserted and the
tool retainer is in a locked position before the ma-
chine is started.
u Check the locking function by pulling the drill steel
outwards forcefully.
WARNING Vibration hazard
Using inserted tools that do not fulfil the criteria men-
tioned below, will result in a longer time to complete a
task, and may result in higher levels of vibration expo-
sure. A worn tool will also cause increased working time.
u
Make sure that the inserted tool is well-maintained,
not worn out and of the proper size.
u Always use a sharp tool in order to work efficiently.
WARNING Injured hands
There is a risk of crushing fingers when changing the
drill steel. To recuce this risk:
u
Never inspect, clean, install, or remove the working
tool while the power source is connected.
u
Never put the fingers between the drill steel retainer
and the chuck.
CAUTION Hot drill steel
The tip of the drill steel can become hot and sharp when
used. Touching it can lead to burns and cuts.
u Never touch a hot or sharp drill steel.
u
Wait until the drill steel has cooled down before car-
rying out maintenance work.
NOTICE Never cool a hot insertion tool in water, it can
result in brittleness and early failure.
5.7.2 Changing drill steel
Whenever changing a drill steel the following instructions
must be observed. Also, make sure that the tool retainer
is of the proper size.
1. When removing the drill steel. Push the tool retainer
outwards, ensure that the tool retainer is fully up.
2. Insert the drill steel in the chuck.
