Operation of the attachment
If you operate the working device joystick quickly, the working device will move quickly; if
you operate the working device joystick slowly, the working device will move slowly.
The attachment is operated by the left and right control pilot valves. The left control pilot
valve operates the bucket arm and slewing (if equipped with a steering yoke, the left control
pilot valve can also control the steering yoke to swing). Joystick of the right attachment
controls the boom and bucket.
When the joystick is released, it will automatically return to the neutral position and the
working device will remain in the original position.
If the pilot valve is operated within 15 seconds of shutting down the engine, the attachment
can still be lowered to the ground.
In addition, the control pilot valve can be operated to release the remaining pressure in the
hydraulic oil line and lower the boom after the machine is mounted on the trailer.
1. Bucket arm control
Push forward the left control pilot valve to extend the
bucket arm; pull it back to retract the bucket arm.
2. Slewing control
When the left control pilot valve swings left, the
platform turns left; when it swings right, the platform
turns right.
For the machine with the swing function of the boom, it
is necessary to make sure that the machine is in the
rotating state before rotating.
3. Boom control
Push the right control pilot valve forward to lower the
boom; pull it back to lift the boom.
