Sharpening the saw chain
12. SHARPENING THE SAW CHAIN
Keep the saw chain sharp. Cutting will be signifi cantly faster and most importantly safer. A blunt saw chain
increases wear on the sprocket, guide bar, chain and engine. If you need to push on the saw and only sawdust
with a few splinters are produced then this means that the chain is blunt.
For this task, we recommend that you contact an authorised service centre
Equipment necessary for sharpening a saw chain
Round fi le as per technical specifi cations
Depth
gauge
File guide
Vice
Medium-size fl at fi le
Sharpening the teeth on the chain
Use the fi le guide set at an angle of 30° (mark A, see
fi gure).
Set the saw chain tension to the correct level.
Fasten the guide bar in a vice so that you have the
chain in a stable position.
NOTE: Do not fasten the chain itself.
Push the round fi le, inserted in the fi le guide, into
the groove between the top plate and the depth
gauge on the chain. The chain should be touching
both the top plate as well as the depth gauge (see
fi gure)
NOTE: File in the middle of the guide bar.
NOTE: In the fi gure you can see the position of the fi le guide and the direction for fi ling the teeth on the left
side of the chain.
Place the fi le guide at the required angle (mark A, see fi gure). Check that the mark is at 30° on the fi le guide
aligned with the centre of the guide bar. This will ensure that you will fi le at an angle of 30°.
File the tooth in the direction from inside out (in direction B, see fi gure) until it is sharp. File only in this
direction.
NOTE: Two to three passes of the fi le should be suffi cient to sharpen the tooth.
