completely before adjusting
the tool or installing

saw chain tension
The Chain Saw is fully assembled,
but may require a minor adjustment
to the Saw Chain tension. Before
using, check the Saw Chain tension.
note: New Saw Chains often need to
be tensioned several times during
first use. Check a new Saw Chain's
tension often when first using.
While wearing heavy duty gloves,
use your index finger and thumb to
carefully grab the Saw Chain in the
middle section under the Guide Bar.
Pull the Saw Chain away from the
Guide Bar. The Saw Chain should
snap back against the Guide Bar. The
Chain should fit snuggly in the groove
of the Chain Bar, yet you should still
be able to slide the chain along the
Chain Bar by hand. There should be
no sagging between the Guide Bar
and Saw Chain on the underside of
the Guide Bar.
