02 Remove the hydraulic pressure
need to turn off the excavator and Remove the pressure from the hydraulic line First
(A button on the pressure valve removes the pressure from the tubing
Force, if the relief valve does not work, you can remove the liquid
Pressure can also be removed from the tank cap)
03 Install the telescopic arm
04 Install the pipe line
05 The telescopic arm already connected
06 Let`s see how to install the bidirectional foot switch
Replace the foot pedal switch with Bidirectional
07 The bidirectional foot pedal switch consists of four connector:
T, P, A1, and A2.
.The T port should be connected to the
T port of the excavator's travel valve
using a three-way joint to separate the
oil flow.
Similarly, the P port should be connected
to the P port of the travel valve using a
three-way connector for oil separation.
Finally, the A1 and A2 connectors should
be connected to the pilot control connector
of the distribution valve.
08 Travel Valve
Remove the rubber pad located on the cab floor to reveal the designated
installation opening for the bidirectional foot pedal switch. Typically, this opening
is situated on the right side of the cab.
Find the T port and P port of the travel valve, which corresponds to the T port
and P port connected to the foot pedal.
09 link pipe
A1 and A2 are connected to the distribution valve. To locate the distribution valve, follow the breaker pipeline and observe where it connects to the distribution valve.
Look for joint positions on both sides of the connection or at the corresponding
middle position, where the valve covers are visible. Connect A1 and A2 to these two positions respectively.
Find corresponding valve covers. The valve cover of the oil inlet pipe is typically
connected to A1, while the valve cover of the oil return pipe is connected to A2.
In the event of reversed action, simply swap the pipelines connected to A1 and A2.
