Check the chain tension frequently for optimum performance and durability.
WARNING!
During operation, hold chain saw firmly with both hands. A single hand operation may cause serious injury.

is excessively loosened, it may get out of the groove in the bar.
• Always wear gloves when touching the chain.

tension adjustment bolt (2) clockwise. To check proper tension,
lightly lift up the center of chain and there should be about 0.5-
1.0 mm clearance between bar and edge of drive link (3).
