Safety and operating instructions

Overview

To reduce the risk of serious injury or death
to yourself or others, read the Safety
instructions section found on the previous
pages of this manual before operating the
machine.

Design and function

The CP 4608 and CP 4611 are designed for medium
to heavy demolition, cutting rivets and bolts, and
other cutting and ripping operations. The machine
can be used both horizontally and vertically. No
other use is permitted.
Recommended insertion tools are listed in the spare
parts list.
NOTICE Do not start the machine without an
inserted tool fitted. Starting the machine without an
inserted tool will cause damage to the impact
mechanism.
CPS
As part of the controlled power system (CPS), the
CP 4608 and CP 4611 monitor the wear of the
bumper and automatically reduces the impact
energy when the bumper is worn out.

Function
When the buster is exposed to back hammering the
impact energy is absorbed by the bumper. Due to
the impact energy the bumper wears away and
causes the upper sleeve and the lower sleeve to
move outwards. At a certain degree of wear of the
bumper, the bleeding ports (J) are opened due to
the outward movement of the upper and lower
sleeves, causing a reduction of the impact energy.
This energy reduction works only when the buster
is exposed to back hammering. If the insertion tool
is pressed firmly against the surface the buster will
start again.
Replacement of the bumper
As soon as the buster is starting to run irregularly or
stops when exposed to back hammering, the
bumper has to be replaced. Continuing to use the
buster when the energy reduction is effective will
cause damage to the retainer and cylinder. When
the wear indicating groove (I) on the lower sleeve
appears from the retainer. It indicates that the
bumper is completely worn out and that the use of
the buster should be stopped and the bumper
replaced.
