4.1.8.
Check the tension of the saw chain. Use your gloved
hand to lift the chain link which positions on the
middle of cutting length up with approximate 10N
force. If the chain link comes completely out of the rail
of guide bar, you need to retighten the chain. (Figure
7)
It is very important to maintain the proper chain tension.
Rapid wear of the guide bar or the chain coming off easily can be caused by
improper tension.
Especially when using a new chain, take good care of it since it may stretch
when first used.
The Spiked bumper belongs to the chain saw. It must be screwed up on chain
saw before the initial use.
Please fix the spiked bumper with two screws on the forefront of the chain
saw.
