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.
