3) Unscrew the nuts (fig.4 item 1) and remove
the brake cover.
4) Remove the plastic or cardboard shim (fig.4
item2) located between the chain brake cover
and the guide bar connecting plate. This shim
is used to hold in position the chain brake cover
for shipping.
DO NOT use it!
5) Turn the chain tensioner screw anticlockwise

bar groove (fig.8). Pull the guide bar to tension
the chain.
9) Refit the brake cover, making sure the
tensioner tooth is correctly inserted in the hole
(fig.7 item x) provided on the guide bar.

vided (fig.9) by keeping the guide bar nose up.

checked and adjusted (with engine off and brake
applied) after a few minutes of chain saw opera-
tion.
