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 box wrench.
    (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.

During operation, hold chain saw firmly 
with both hands. A single hand operation 
may cause serious injury.

WARNING!

Never try to start engine without side case 
securely fastened.
1. Remove chain bar clamp nuts (3).
2. Remove the side case (1) as pinching the
    rear part of the side case (1) .(Fig. 1-1)
  * Install the spiked bumper (1) (If so equipped)  
    to the unit with the two screws. (Fig.1-1B) 
3. Install, the chain bar (1) onto the bolts (2),
    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)
