Adjusting chain Tension (fig. 9–10)
CAUTION:
Sharp chain. Always wear protective
gloves when handling the chain. The chain is sharp and can cut
you when it is not running.
WARNING:
accidental operation, ensure that battery is removed from the tool
before performing the following operations. Failure to do this could
result in serious personal injury.
• With the saw on a flat, firm surface, check the saw chain (E) tension. The
tension is correct when the chain snaps back after being pulled 1/8 inch
(3mm) away from the guide bar (D) with light force from the index finger
and thumb as shown in figure 9. There should be no "sag" between the
guide bar and the chain on the underside as shown in figure 10.
• To adjust saw chain tension, flip up locking tab and rotate the
bar adjust locking knob (G) counterclockwise one full turn. Rotate
the chain tensioning knob (H) clockwise until the chain tension is
correct as instructed above.
• Do not over-tension the chain as this will lead to excessive wear
and will reduce the life of the bar and chain.
• Once chain tension is correct, securely tighten bar adjust locking knob.
note: The bar adjust locking knob has a detent tightening system.
The sprocket cover is secure after three audible clicks are heard.
Further tigtening is not required.
• When the chain is new, check the tension frequently (after removing
battery) during the first 2 hours of use as a new chain stretches slightly.
