14 Assembling the Pole Pruner
► Direct the drive links into the groove of the guide bar (6,
arrow) while turning the side chain tensioner (3) clockwise
until it stops.
The guide bar and chain must be firmly and securely
mounted on the pole pruner.
► Fit the sprocket cover on the pole pruner so that it is flush
with the housing.
► Turn the nut clockwise until the chain sprocket cover is
firmly attached to the pole pruner.
14.3.2 Removing the Guide Bar and Chain
► Unscrew the nut securing the chain sprocket cover.
► Remove the chain sprocket cover.
► Turn the side chain tensioner counterclockwise until it
stops and the chain is loose.
► Remove the guide bar and chain.
NOTICE
The top and bottom of the guide bar are symmetrical, and
the bar may be mounted with the printing facing up or down.
Flipping the guide bar each time the chain is sharpened or
changed will help reduce uneven wear and improve its
service life.

14.4 Tensioning the Chain
WARNING
To reduce the risk of severe personal injury from chain
derailment, check chain tension frequently, @ 6.5. At
operating temperatures, the chain stretches and sags. New
chain tends to stretch more than used chain. Tension the
chain so that the drive links cannot come out of the groove
on the underside of the guide bar.
To properly tension the chain:
► Switch off the pole pruner, @ 16.2.
► Remove the battery, @ 15.2.

► Loosen the nut (1).
► Lift the guide bar tip.
► Turn the side chain tensioner (2) clockwise to tighten the
chain.
The chain is properly adjusted when the distance between
the underside of the guide bar and the chain (a) is
between 0.04 in. (1 mm) and 0.08 in. (2 mm) and can still
be pulled easily along the bar by hand. Always wear
gloves when handling the chain.
► If the chain cannot be moved along the guide bar, it is too
tight.
