11.2 Chain tensioning and adjustment check
See fig 7
Note: if chain is difficult to rotate on guide bar or if it binds, too much tension has been
applied. This requires minor adjustment as follows:
Loosen the bar retaining nuts so they are finger tight. Decrease tension by turning the bar
adjustment screw counter clockwise slowly. Move chain back and forth on bar. Continue to
adjust until chain rotates freely, but fits snugly. Increase tension by turning bar adjustment
screw clockwise.
When saw chain has proper tension, hold nose of bar in the uppermost position and tighten
the 2 bar retaining nuts securely.
Caution: a new saw chain stretches, requiring adjustment after as few as 5
cuts. This is normal with a new chain, and the interval between future
adjustments will lengthen quickly.
Caution: if saw chain is too loose or too tight, the sprocket, bar, chain, and
crankshaft bearings will wear more rapidly. Study Fig. 12 for information
concerning correct cold tension (A), correct warm tension (B), and as a
guide for when saw chain needs adjustment (C).
11.3 Check of the chain oil level
See fig 8 and “9 BEFORE STARTING UP”
12 OPERATION
12.1 To start
See fig 9
WARNING: Never start or operate the saw unless the bar and chain are
properly installed.
Caution: while the saw is cutting, be sure the chain and bar are being
properly lubricated.
▪ To switch the machine on push the lock-off button and the on/off switch trigger at the
same time.
12.2 To stop
See fig 10
Chain runs out briefly after switching off.
Do not adjust the chain lubrication system unless the motor has been
turned off.
