Check the round attack picks
Check the round attack picks daily, before and
after operation.
◆
Check whether all round attack picks are in
place.
◆
Check the round attack picks, and in particular
the tungsten carbide tips for wear and
breakages.
The head lengths of the individual round attack
picks must be evenly worn, to avoid additional
vibrations on the cutter drums.
◆
If one or more round attack picks are worn,
replace them immediately.
◆
Check movement of round attack picks in the
pick boxes. The play of the pick shaft diameter
in the pick box must not exceed 0.3- times the
pick shaft diameter.
◆
If one or more round attack picks exhibit play of
more than 0.3- times the pick shaft diameter,
have the pick box or the wear sleeve
immediately replaced.
Contact the Atlas Copco Customer Center/
dealer in your area.
Replace round attack picks
◆
You must replace the round attack picks:
•
if the tungsten carbide tip is worn.
•
if the head lengths of the round attack picks
are different.
•
in case of cracks between the shaft and the
head.
DANGER Risk of death due to use of old
parts
Using old parts (old hydraulic hoses, screws or
retainers) can lead to accidents, which may in turn
result in severe injuries.
►
Only use new parts.
►
Only use original parts.
Note: There are four different locking systems for
the round attack picks. Depending on the design of
the transverse drum cutter, the round attack picks
can be retained in the pick box with a range of
retainers. This also determines the procedure and
the tools required to change the part. The four
different methods of changing the round attack
picks are described in the text that follows.
