4.6 CUTTING BLADE AND DRIVE END
If the cutting blade of the machine does not penetrate the wood properly or the cut is skewed, the saw
chain is most likely blunt. It is a good idea to keep a replacement chain handy, so that you do not need to
interrupt your work to sharpen the chain.
Replacing and tightening the saw chain
Replace the saw chain as follows:
1.
Turn off the machine and disconnect it from its power source.
2.
Open the guard.
3.
Loosen saw bar bolts B (Figure 24).
4.
Fully loosen adjustment screw A for saw chain tension (Figure 24).
5.
Remove the old saw chain.
6.
Install the new saw chain and ensure that the cutting teeth come first in relation to the rotating direc-
tion.
7.
Lift the saw bar from the front section to tighten the chain as you are attaching the bolts.
8.
Use adjustment screw A to tighten the chain and tighten fastening bolts B (Figure 24).
To check the tension of the saw chain, wear protective gloves and pull the lower edge of the chain.
The tension is correct if you can pull out three to four teeth of the chain
into full view
by applying
moderate force.
Note! Use protective gloves when handling the saw!
