ASSEMBLING AND ADJUSTMENTS
General
Prevent dirt from entering the hydraulic system by:
• Wiping dirt off the couplings before assembling or
dismantling.
• Placing dust guards on the machine’s hydraulic couplings
when no tool is mounted.
• Ensuring that the tool’s hoses are always connected
together when the tool is not connected to the machine.
Mount tool on machine
•See the operator’s manual for the demolition machine for
instructions.
Connect the hydraulic hoses
The hydraulic hoses are equipped with quick couplings with
decompression. This facilitates fitting the hoses even though
pressure is trapped.
• Connect the male connection on the tool to the female
connection on the machine. The nut should snap when
properly mounted.The couplings are locked by turning the
outer sleeve on the female coupling so that the slot moves
away from the ball.
• Connect the female connection on he tool to the male
connection on the machine.
• Start the motor.
• Open and close the jaws 5-6 times.
• Turn off the motor.Turn the main switch to the "0"-position.
• Check for leaks.
Disconnect the hydraulic hoses
• Open the jaws to the maximum to retract the hydraulic
cylinders completely.
• Turn off the motor.
• Rotate the outer sleeve so that the slot coincides with the
ball and push towards the ball to disconnect the
connection.
• Remove the tool from the machine. See the operator’s
manual for the demolition machine for instructions.
Adjusting movable jaws (DCR 100)
It is possible to adjust the opening of the jaws by moving the
position of the pins in two different slots.
The jaws can be adjusted for cutting material with a thickness
of 31 mm to 430 mm.
• Insert the pin unlocking wrench and push until the pin
unhooks. Extract the pin.

conexión macho de la máquina.
• Arranque el motor.
• Abra y cierre la mordaza 5-6 veces.
• Pare el motor. Seleccione la posición «0» del interruptor
principal.
• Compruebe que no haya fugas.
Desacoplar las mangueras
hidráulicas
• Abra la mordaza al máximo para bajar totalmente los
cilindros hidráulicos.
• Pare el motor.
• Gire el manguito externo hasta que la ranura coincida con
la bola y empújela para desconectar la conexión.
• Extraiga la herramienta de la máquina. Consulte el
manual de instrucciones de la máquina de demolición.
Ajuste de la mordaza móvil
(DCR 100)
Coloque las clavijas en una de las dos ranuras para ajustar la
apertura de la mordaza.
La mordaza puede ajustarse para cortar grosores de 31 mm
a 430 mm.
