Removing the hammer (quick fastening)
The hammer is operated from the operator's stand via the hydrau-
lically actuated unlocking device.
1 Place the machine on firm and level ground.
2 Lower the boom and lay the hammer flat on the ground.
3 Turn the black safety rings and pull them back to unlock the hy-
draulic couplings.
4 Disconnect the hydraulic hoses of the hammer from the hy-
draulic connections on the boom.
5 Position the quick release device with the hammer under an
angle of 90°.
6 Press the unlocking switches (1) and (3) together to activate
the hydraulic unlocking of the hammer from the quick fastening.
Changing the hammer tool
Three tools are available for the hammer: Pointed chisel (A), flat
chisel (B) and spade (C). The hammer tools are suitable for vari-
ous applications.
Changing the hammer tool
The hammer tool can be changed by loosening the retaining ta-
pers.
1 Insert a screwdriver through opening (A), press on latch (2) and
slide it completely back into its receptacle. Hold the latch de-
pressed.
2 Insert a rod into opening (B) and knock out taper (1), which is
no longer locked by latch (2).
3 Follow the same procedure, but through openings (C) and (D),
to unlock and remove the second retaining taper.
4 Pull the hammer tool out of its receptacle and replace it with the
desired tool.
5 Clean and crease the retaining tapers before assembly.
WARNING!
Before removing or connecting hydraulic hoses the engine
must be shut down and the control levers shifted to all
directions, in order to relieve any trapped pressure. It must
be strictly assured that the engine cannot be started after
hydraulic couplings have been opened.
WARNING!
Safety regulations, operating instructions and maintenance
instructions issued by the hammer manufacturer must be
strictly observed!
