NOTE: Chain should rotate freely and be free of
kinks.
7. Fit the Chain Cover (12) and tighten the Chain Cover
by turning the Chain Tensioning Knob (11) clockwise
until it is tight. (See Fig. D)
WARNING:
The chain is not yet tensioned.
Tensioning the chain applies as described
under “TENSIONING CHAIN”. The chain now
needs to be inspected to make sure it is properly
tensioned.
TENSIONING CHAIN (See Fig. E1, E2)
NOTE:
New saw chains will stretch. Check the chain
tension frequently when first used and tighten when the
Chain (10) becomes loose around the Guide Bar (9).
WARNING:
• Unplug chain saw from power source before
adjusting saw chain tension.
• Cutting edges on chain are sharp. Use
protective gloves when handling chain.
• Maintain proper chain tension always. A loose
chain will increase the risk of kickback. A
loose chain may jump out of guide bar groove.
This may injure operator and damage chain. A
loose chain will cause chain, bar, and sprocket
to wear rapidly.
1. Place the chain saw on any suitable flat surface.
2. Turn the Chain Tensioning Knob (11) clockwise until it
is hand tight.
NOTE:
The tension is automatically increased while the
Chain Tensioning Knob (11) is being turned in a clockwise
direction. The ratchet mechanism prevents the chain
tension from loosening.
3. Tilt the saw forward (See E1) where the Guide Bar (9)
tip is pushed in an upward direction. This will remove
slack from the chain.
4. Fully tighten the Chain Tensioning Knob (11) by
turning it clockwise.
5. Double check the tension set by the automatic Chain
Tensioning Knob. The correct chain tension is reached
when the Chain (10) can be raised approx. half the
drivelink depth from the Guide Bar (9) in the center.
This should be done by using one hand to raise the
chain against the weight of the machine. (See Fig. E2)
NOTE: The Chain (10) is properly tensioned when it can
be lifted off of the Guide Bar (9) and the drivelink is
within the rail of the Guide Bar (9).
