already installed, turn chain tension screw counter clockwise 2 to 3 turns.
IMPORTANT: Always loosen sprocket cover locking nut before turning the
chain tension screw or else the sprocket cover and tension adjuster
will be damaged.
2. Move the chain tensioning pin fully back towards the sprocket using the chain tension
screw. (See direction arrow)
3. Place the guide bar onto the bar studs so that the chain tensioning pin ts into the hole
in the guide bar.
4. Install chain over clutch and place around the sprocket and guide bar.

runs.

sprocket cover locking nut nger tight.

screw clockwise until saw chain touches the bottom of the guide bar.
8. Tighten the sprocket cover locking nut using the wrench provided, keeping the guide
bar nose up while tightening the nut.
9. Pull the saw chain around the guide bar by hand to check for tight spots. Saw chain should move freely but not
sag. If too tight loosen the guide bar nuts and adjust using the chain tension screw.
Caution: Proper saw chain tension is extremely important. If saw chain is too tight, the guide bar
and saw chain will be quickly damaged. If the saw chain is too loose, it may get out of the guide
bar groove and cause an injury.
Note: A new chain will stretch so adjust the tension after a few cuts. Watch saw chain tension carefully for
the rst half hour of cutting.
WARNING - Check the chain tension before each use.
Always use protective gloves.
WARNING - Never try to run the chainsaw without sprocket
cover securely tightened.
