NOTE: The saw chain (3) has not yet been tensioned.
Tension the chain as described under “Saw chain
tensioning”. After operating the product for approximately
1 hour, adjust the chain tension again.
Saw chain tensioning
Always check the saw chain tension before use, after rst cuts
and regularly during use, approximately every ve cuts. After
initial operation, new chains can lengthen considerably. This is
normal during the break-in period and the interval between future
adjustments will lengthen quickly.
WARNING! Unplug the product from the power source
before adjusting the saw chain tension!
The cutting edges of the saw chain are sharp. Always
wear protective gloves when handling the chain!
Always maintain proper chain tension! A loose chain
increases the risk of kickback! A loose chain may jump out
of the guide bar groove! This may injure the operator and
damage the chain! A loose chain will cause rapid wear to
the chain, guide bar and sprocket!
Tensioning the chain too tightly will overload the motor and
cause damage, and insufcient tension can cause chain
derailing, whereas a correctly tightened chain provides
the best cutting characteristics and prolonged working life!
The chain life mainly depends upon sufcient lubrication
and correct tensioning!
