Once the chain is tight, rotate the multi-tool upward to
properly engage the teeth from the lock/latch into the
tightener teeth. If the tightener will not skip a tooth before
tightening, do
NOT
force the tightener to the next notch.
IMPORTANT:
Do
NOT
overtighten the chain. If overtightened, the chain
will put excessive loads on the sprockets, causing the motor
bearings and/or other components to fail prematurely.
IMPORTANT:
There should be approximately 38 mm (1 1/2 in.) of play on
one side (A) of the chain, while it is tight on the other
side (B). This level of tension and play in the chain is
required to skip one notch on the chain tightener.

Rotate the reel by hand to verify that the chain is still
engaged properly on all teeth on lower sprocket (A). To
prevent damaging components, ensure the chain does not
get too tight as the reel is rotated.

Return the multi-tool to the storage position.
