Preparing to Operate the Chainsaw
Step 2 - Adjust the chain tension
1a Slightly loosen the chain cover nuts.
1b Take off the blade protector. While holding up the tip of the bar, adjust the chain tension by
turning the tensioner screw until the chain engages in the bar channel.
NOTE! when tensioned correctly it should be possible to pull one full chain link free of the bar
channel with ease.
- A new chain will expand its length during the first period of use. Check and re-adjust the tension
frequently as a loose chain can easily derail or cause rapid wear of itself and the chain bar.
CAUTION! If the saw chain is TOO LOOSE or TOO TIGHT the V-drive wheel, chain bar, chain
and crank shaft bearing will suffer premature wear. Above fig. shows the correct tension A (when
cold) and tension B (when warm). FIG C shows a chain that is too loose.
