4. Mount the bar
(with the chain fitted)
introducing the
tensing pin (B) in the hole of the bar and
placing the chain around the attacking pinion.
5. Place the bar cover back in place ensuring the
tensing pin is still in the hole of the bar.
6. Place the bar cover nut back in place but do not
tighten fully.
7. Turn the tensing screw clockwise to tense the chain
and anticlockwise to untense the chain until the
chain tension is adequate (follow instruction in
point 6.2.2).
8. Tighten the bar cover nut fully.
9. Check that the chain slides along the bar
maimtaining at all times the tension when you
move it with your gloved hands. If needed, repeat
the process until the chain is mounted correctly.
New chains have a certain dilatation when first
used. Verify and regulate the tenion of the chain
regularly. An incorrectly tensed chain will wear out
quickly and will also wear out the guide of the bar.
6.2.2. TENSING THE CHAIN
1. Ensure that the chain is in the inside of the bar
guide.
2. Loosen the nut of the chain cover.
3. Turn the tensing screw (1) clockwise to tense the
chain and anticlockwise to untense the chain until
the chain tension is adequate.
a. In example (A) the chain is too tense.
b. In example (B) the chain is not tense enough.
4. Tighten the nut of the chain cover. Do not tense the
chain too much.
NOTES:
The chain dilates with heat. When the chain is cold the
tension will be more than whe hot.
If you tense the chain when cold, you will have to
check the tension after just a few cuts (the chain will
have reached its working temperature) as it will have
expanded when it heats up and will loosen itself and it
could come out from the bar chain guide. Retense the
chain if necessary.
If the chain is tensed again when hot, you must check
the chain tension when you have finished work as
when the chain cools down it will tend to tense and if
too tense it could damage the chain.
New chains need some time until the teeth adapt
and this could modify slightly the length of the chain.
