Hello,

We have a RD3020-30-S that has developed a problem today. I would appreciate any help or advice as to how to resolve it.

The machine has always had two lifting modes: When the joystick was moved up partially a first mode/motor/pump would activate and the forks would lift at a slower rate. When the joystick was moved up fully a second mode/motor/pump would activate and the forks would lift at a faster rate.

Today the machine was lifting in just one mode: When the joystick was moved up partially a relay could be heard clicking but the first mode/motor/pump would not activate and the forks would not lift. When the joystick was moved up fully a second mode/motor/pump would activate and the forks would lift but only at a slower rate.

How do I troubleshoot the missing first mode/motor/pump?

Thanks in advance for taking the time,
Robert
