3.1.2 TENSIONING CHAIN
-Always check the chain tension before use, after the first cuts and regularly during
use, approx. every 5 cuts.
-Upon initial operation, new chains can lengthen considerably. This is norm
al during
the break-in period, and the interval between future adjustments will lengthen quickly.
WARNING: Unplug the chain saw
from the power source before
adjusting the saw chain tension.
WARNING: Cutting edges on the chain are sharp. Use protective
gloves when handling the chain. The chain will be hot after cutting
material.
WARNING: Maintain proper chain tension always. A loose chain will
increase the risk of kickback. A loose chain may jump out of the guide
bar groove. This may injure the operator and damage the chain. A loose
chain will cause the chain, chain bar and sprocket to wear rapidly.
