ASSEMBLY PROCEDURES

WARNING
Never try to start engine without side case, guide bar and chain
securely fastened.
1. Pull the front hand guard (2) toward the front handle to check that

3. Install the guide bar (6) onto the bolts (7), then push it toward the
sprocket (8) as far as it will go. (Fig. 5)
4. Confi rm the direction of saw chain (9) is correct as in the fi gure,
and align the chain on the sprocket (8). (Fig. 5)
5. Guide the chain drive links into the bar groove all around the
guide bar.
6. Install the side case (4) onto the bolts (7).

tension adjustment bolt (12) clockwise. To check proper tension,
lightly lift up the center of chain and there should be about 0.5 –
1.0 mm clearance between guide bar and edge of drive link (13).
(Fig. 7, 8)
CAUTION
PROPER TENSION IS EXTREMELY IMPORTANT
8. Raise the guide bar end and securely tighten the guide bar
clamp nut (3) with the combi box spanner (14). (Fig. 9)
9. A new chain will stretch so adjust the chain after a few cuts and
watch chain tension carefully for the fi rst half hour of cutting.
NOTE
Check the chain tension frequently for optimum performance
and durability.
CAUTION
○ When the chain is excessively tightened, the guide bar and
chain will be damaged rapidly. Conversely, when the chain is
excessively loosened, it may get out of the groove in the guide bar.
○ Always wear gloves when touching the chain.
WARNING
During operation, hold chain saw fi rmly with both hands. A single
