Replacing and tightening the out-feed conveyor belt
The instructions for tightening and aligning the out-feed conveyor are presented in Section 4.6.
Replace the out-feed conveyor belt as follows:
1. Pull out the pin locking the conveyor in place and lower the conveyor to the ground.
2. Shut the machine down and disconnect it from its power sources.
3. Move the belt joint to the start of the conveyor.
4. Fold the conveyor, but do not place the belt support in the transport position. This will allow the belt to
hang loose.
5. Disconnect the joint by opening the bolts.
6. Remove the old belt.
7. First, insert the new belt under the folded conveyor (bottom opening) from the end of the conveyor with
the plates facing downwards. Feed the belt in until you can pull it out from the other end of the conveyor.
Pull out a length of approx. 60 cm.
8. Push the other end of the belt into the upper section of the folded conveyor (top opening) from the end
of the conveyor. Feed it in until you can connect the joint.
9. Pull the excess belt to the start of the conveyor.
10. Open the conveyor to the operating position, and tighten and adjust the belt.
The belt is at the correct tension when its middle section is raised approx. 15 cm when the conveyor is in the
operating position and the belt tensioning springs are not fully compressed during operation. An excessively
tight belt may be damaged more easily, and it places unnecessary strain on the conveyor bearings.
Replacing the out-feed conveyor plates
The out-feed conveyor plates can be replaced by disconnecting the bolt joints (3 x M8) fastening the plates and
replacing the plates with new ones. It is recommended that you move the belt into a position that puts the plate
to be replaced above the conveyor. Turn off the machine and disconnect it from the power source for the dura-
tion of the procedure.

LUBRICATION

All of the firewood processor's lubrication points, which require Vaseline, have been labelled. There are
nine lubrication points, presented in Figures 35–40. In order to access all grease nipples, remove the bolt
pin and bolt of the lifting lug (Figure 35). Loosen the bolts circled in Figure 36 (or loosen them enough to
slide the plate out) and remove the cover plate.
Lubrication every 50 hours:
1. Grease nipple of the wood limiter in Figure 40.
2. Guard nipples (2 pcs) in Figures 41 and 42.
3. Mechanisms (nipples in Figures 45–47).
Lubrication every 200 hours:
1. Grease nipple of the in-feed conveyor drive roller bearing in Figure 39.
2. Hinged nipples of the saw control shaft (2 pcs) in Figures 37 and 38.
3. Nipples (2 pcs) of the out-feed conveyor drive roller bearings in Figure 43.
Note! Do not apply too much grease on the bearings to avoid damaging the dust covers!
