then push it toward the sprocket (3) as far as
it will go. Make sure that the boss of chain
tension adjust bolt (4) fits into the hole of the
bar (5). (Fig.1-2)
NOTE!
Slightly move the bar back and forth and make
sure the chain tension boss (4) fits into the hole
(5) in the bar properly.

7. Raise the bar end, and tighten the chain (1)
by turning the tension adjustment bolt (2)
clockwise. To check proper tension, lightly
lift up the center of chain and there should
be about 0.5-1.0mm clearance between bar
and edge of drive link (3). (Fig.1-4, 5)
CAUTION!
PROPER TENSION IS EXTREMELY IM-
PORTANT!
8. Raise the bar end and securely tighten the
chain bar clamp nuts with the combi box
spanner. (Fig. 1-4)
9. A new chain will stretch so adjust the chain
after a few cuts and watch chain tension
carefully for the first half hour of cutting.
NOTE!
Check the chain tension frequently for
optimum performance and durability.
CAUTION!
When the chain is excessively tightened, the
bar and chain will be damaged rapidly.
Conversely, when the chain is excessively
loosened, it may get out of the groove in the
bar.
Always wear gloves when touching the chain.
