4.3.1. Jamming of the cutting blade
If the cutting blade gets jammed in the log, stop sawing and try again on another section of the log. If the cut
is misaligned because the bar drags to one side, the degree of sharpness of the saw chain must be checked. A
chain that is not evenly sharp will always drag towards the blunter side, which will make cutting a thick log
impossible. Also check that the bar is not worn or crooked. On the other hand, sawing with an evenly dull
chain is inefficient, and the sawing chain must be sharpened or replaced (see Sections 5.1.1 and 5.1.2).
4.3.2. Sawing the last log
When sawing wood, the second to last piece should be sawn in such a way that the remaining piece is of a
sufficient length. This ensures that the log will stay firmly under the wood gripper and that the sawing will be
steady and safe. Drive the last log directly into the splitting section, and start the splitting process using
joystick button A (Figure 11).
4.3.3. Using the quick couplings of the additional hydraulics
Connect the additional hydraulics (e.g. when using the HakkiFeed 381 log lifter) by pushing the auxiliary
device's hydraulic hoses into quick couplings A and B in Figure 20 (in Section 4.3.4). The hose with red marking
goes to higher quick coupling (also marked with red colour).
4.3.4. Using the quick couplings of the auxiliary feed rollers
The auxiliary feed rollers can be connected in series with the in-feed conveyor. This way, the rollers are
automatically synchronised to operate with the input conveyor when feeding logs using joystick E (Figure 10).
1. Connect the auxiliary feed roller
hoses to quick couplings C and D,
hose with red marking to higher
quick coupling
2. Remove the guard as instructed in
the instructions of point 2 of
Section 4.4.4.
3. Open cock E (Figure 21) to allow oil
to flow to the quick couplings
(Figure 20) C and D.
4. Make sure that the rotation
direction of the rollers is the same
as the conveyor's direction. If
necessary, change the connections.
