4.3. SAWING
The barsaw is always operating.
The sawbar movement is performed using the sawbar activation handle (H-Figure: 7), during which the sawed
log must be held using the retaining handle (P-Figure: 7). When the sawing begins, the trapdoor (13-Figure: 8)
moves away automatically, so the log can fall freely into a splitting chute after the cut.
Adjust the sawbar moving speed according to the hardness of the wood. Finish the cut (app. last 20 mm - last
1 in) with rapid downward movement of the sawbar activation handle, to make the cut log fall into the chute
correctly.
When cutting hard wood, the cut log can fall into the chute and rebound in the air - and splitting cylinder can
grab it sideways*, which can cause the jam and even damage to the machine. To avoid this, hold the sawbar
activation handle after the cut in lower position, to allow the cut log to correctly position itself in the chute.
Only then lift the sawbar activation handle to activate one of the two splitting cylinders.
*
… in this case quickly switch the cylinders or open the machine cover, to stop the splitting cylinder
and reposition the cut log.
4.3.1. ADJUSTING THE WOOD LENGTH
The length of the firewood is set by adjusting the position of the length limiter (15-Figure: 8), which is fixed
in the required position using the fixing pin (14-Figure: 8).
4.4. SPLITTING
Splitting is performed by a splitting cylinder that pushes the log towards a splitting wedge. The splitting speed
depends on the wood resistance and changes during splitting. Since the splitting speed is inversely
proportional with the splitting force, the splitting cylinder enables greater splitting force at a lower speed and
smaller splitting force at a greater splitting speed. The splitting cylinder automatically selects the necessary
speed or splitting force, which results in greater energy efficiency.
The activation of splitting cylinder is performed by lifting the sawbar activation handle (H-Figure: 1), after the
log has been cut or using the cylinder operating handle (C-Figure: 9). Cylinder operating handle (C-Figure: 9)
can also be used at any time, to move the Cylinder Piston to the starting position, which is sometimes required
in practice to prevent jamming during the splitting phase.
The force on the sawbar activation handle should not exceed 100 N. Greater force can cause increased
vibrations of the belt, which may result in damage to the belt. Check the tension of the belt (Chapter:
5.9.).
