clockwise (Fig. 3).
Do not tighten the retaining nut (5) completely, saw chain
tensioning is required first.
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 first
cuts and regularly during use approximately every five 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 insufficient tension can cause chain
derailing, whereas a correctly tightened chain provides the
best cutting characteristics and prolonged working life.
