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)

    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.

Never try to start engine without side case 
securely fastened.
