Adjustment valve No.3 for proceeding speed of crosscut blade, Fig. 12, 

only in s-model 

 

When the valve is turned clockwise, the proceeding speed decreases, and when turned 

counter-clockwise, it increases. 

 

For thick logs, it pays to reduce the proceeding speed. This decreases the load on the 

transmission and the crosscut blade. 

 

Reducing the proceeding speed slightly does not affect the total processing time, 

because splitting a thicker log also takes more time. 

4.5

 

Joystick-valve, No. 4, Fig. 13 

 

Press the lever to the right to launch the splitting. 

 

Press the lever to the left to stop the splitting and to reverse the cylinder. 

 

MECHANICAL CONTROL OF THE PALAX C750 Ergo USING THE 

MULTI-FUNCTION LEVER 

 

The crosscut operation, launching the splitting and operation of the infeed conveyor are 

effortlessly controlled using multi-function lever 3, Fig. 14. The movement path and all 

movements are precise as the shaft and the controls are all equipped with roller bearings. 

5.1

 

Mastering the safety devices 

1.  The crosscut blade does not come down - close the protective net for the splitting 

chute. The machine does not operate, if the protective net is open. 

2.  The protective net for the splitting chute cannot be opened – press the multi-

function lever completely to the right. The protective net cannot be opened, unless 

the multi-function lever is positioned completely to the right. 

3.  The splitting operation cannot be launched with manual control – close the 

protective net for the splitting chute. The machine does not operate, if the protective 

net is open. 

5.2

 

Control levers for PALAX C750 Ergo, Fig. 14A 

1.  Manual start of the splitting. 

2.  Multi-function lever. 

3.  Control lever for splitting wedge. 

 

Operation of the multi-function lever 3, Fig. 14A 

 

Direction A, crosscut operation. 

 

Direction A; raising the crosscut blade and simultaneous launching of the splitting. In 

the extreme position to the right, the functions are locked, enabling opening of the net 

cage. 

 

Direction C; as the crosscut blade is raised to its upper position, the lever 3 can be 

pressed in direction C to advance the log using the infeed conveyor. 

 

Direction D; in the same position, the lever can be pulled out to make the infeed 

conveyor reverse.
