8. Tighten the Chain Cover by turning the Chain
Tensioning Knob (10) 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
NOTE:
New saw chains will stretch. Check the chain
tension frequently when first used and tighten when the
Chain (8) becomes loose around the Guide Bar (7).
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 (10) clockwise until
it is hand tight. The tension is automatically set while
the Chain Tensioning Knob is being tightened.
The ratchet mechanism (a) prevents the chain tension
from loosening (See Fig. E2).
3. Double check the tension set by the automatic Chain
Tensioning Knob. The correct chain tension is reached
when the Chain (8) can be raised approx. 3-6mm
from the Chain Bar (7) in the center. This should be
done by using one hand to raise the chain against the
weight of the machine (See Fig. E1).
Use a screwdriver to move chain around Guide Bar
to ensure kinks do not exist. The chain should rotate
freely (See Fig. E3).
4. The Chain will stretch from use and lose proper
tension. To retension the chain simply repeat steps
1 - 3 listed above.
LUBRICATION
IMPORTANT: The chain saw is not supplied
filled with oil. It is essential to fill with oil
before use. Never operate the chain saw without
chain oil or at an empty oil tank level, as this will
result in extensive damage to the product.
