Replacing and tensioning the saw chain
The Hakki Pilke 50 Pro firewood processor comes standard with a patented AC10™ automatic and
hydraulically powered saw chain tensioner. When the machine is running, the hydraulic cylinder pushes
the saw motor backwards with a constant force, keeping the saw chain’s tension optimal. The operator
does not need to worry about the saw chain’s tension.
Replace the saw chain as follows:
1. Turn off the machine, disconnect it from its power source and open the machine guard.
2. Turn lever A (Figure 24) to the OFF position to release the pressure in the automatic saw chain
tensioner.
3. Put on gloves and pull the saw chain downwards at the middle of the beam. This will loosen the chain
and allow you to remove it.
4. Install the new saw chain and ensure that the cutting teeth come first in relation to the rotating
direction.
5. Turn lever A (Figure 25) to the ON position, as shown in Figure 24.
6. Close the machine guard and turn on the machine. This will automatically tension the saw chain to the
right tension and raise the saw bar.
Figure 24.
To check the tension of the saw chain, wear protective gloves and pull the lower edge of the chain at the
middle of the beam. The tension is correct when you cannot pull a drive tooth to a fully visible position
with moderate force, but the chain moves on the bar when pulled with a tool.
