Pull the chain around the bar to be sure the drive links are

properly seated in the drive sprocket.

Now replace the outer bar plate.

Replace the clutch cover, tightening the clutch cover nuts

only finger tight.

SECURING THE BAR & CHAIN

Wearing gloves or with a shop rag protecting your hand,

pull up on the tip of the bar. While holding up the bar tip,

tighten the chain tension adjustment screw by turning it

clockwise.

While still holding up the bar tip, tighten the

clutch cover nuts (Fig. 9). Holding up the tip of the bar takes

out any slack between the bar mounting slot and the two

mounting studs. This will eliminate any upward movement

of the bar when cutting pressure is applied at the bottom of

the bar. Any such upward movement of the bar would cause

the chain to loosen.

CHAIN TENSION

Proper chain tension is a key factor in reducing carbide

breakage and increasing guide bar life. Proper chain ten-

sion has the chain as tight as possible without restrict-

ing chain movement.

At proper tension, the chain should move along the bar

freely.

You should feel only the resistance of the sprocket

and clutch drum turning. If the chain does not move

smoothly i.e., catches or requires excessive force to move,

it is too tight. At proper tension, the chain is in full contact

with the bar along the bottom rails, there is no "sag".

At the midpoint along the bottom rails, when pulling down

on the chain, you should be able to pull the chain away from

the rails - to the distance where point of the drive link is "just

Proper chain tension setting requires a fully lubri-

cated "broken-in" chain. See "Running-in the chain

Please note that each time you fill up or top off the

fuel tank, always top off the bar and chain oil tank.

The fuel tank and the bar and chain oil tank are

sized so that the saw will always run out of fuel

before it runs out of bar and chain oil, eliminating

the possibility of running the chain dry.
