“AutoStart” integration setting
♦
Remove the plug (B) from the breaker box.
♦
Remove the plug (C). It is located in the cylinder
behind plug (B).
♦
Screw a screw (M 10) into the valve piston (D).
♦
Pull the valve piston (D) by its screw from the bore
in cylinder (A).
♦
Remove the screw from the valve piston (D) and
install it again the other way around.
♦
Screw in the plug (C) and tighten it to the required
tightening torque (see chapter Bolt connections /
Tightening torques).
♦
Install the plug (B) in the breaker box.
PowerAdapt
PowerAdapt protects the hydraulic breaker against
hydraulic overloads and switches it off if the hydraulic
input energy is too high.
An overload occurs when the hydraulic breaker is
operated while the delivery rate and the pressure
from the carrier are too high. The carrier driver can
correct this by reducing the engine speed or setting
a lower mode stage on the carrier.
Adjusting the delivery rate:
♦
Start the carrier.
♦
Set the maximum speed and the highest mode
stage.
♦
Switch on breaker operation.
If the hydraulic breaker fails to work:
♦
Lower the speed or the mode stage and restart
the hydraulic breaker.
♦
Repeat this until the hydraulic breaker works
continuously without failures.
The oil volume can be increased after the heat-up
phase.
The advantage of PowerAdapt is that manual
adjustment puts the maximum percussion energy at
your disposal, without overloading the hydraulic
breaker.
Hydraulic adjustment of the carrier to enable working
with the hydraulic breaker is still necessary, in spite
of using PowerAdapt. PowerAdapt is not a
pressure-relief valve.
