with the engine off.
– Unscrew the nut (1) and remove the cover (2) to
get to the drive sprocket and point where the bar
is to be fitted (Fig. 2).
– Mount the bar (4) by inserting the stud bolt (3) in
the groove and push it towards the back of the
starter unit (Fig. 3).
– Mount the chain in the right direction around the
drive sprocket and along the bar rail (Fig. 4). If
the tip of the bar has a nose sprocket, make sure
the drive links fit correctly in the sprocket rims.
– Check that the chain tension adjuster pin (5) is
fitted properly in the hole on the bar; if it isn't,
turn the chain tension adjuster screw (6) using
a screwdriver until the pin is completely inserted
(Fig. 5).
– Fit the guard (2) back on without tightening the
nut (1).
– Turn the chain tension adjuster screw (6) to ad-
just the chain tension (Fig. 6).
– Raise the bar (4) and tighten the nut (1) on the
guard (2) securely using the wrench (Fig. 7).
– Check the chain tension. The tension is correct
when the drive links do not slip out of the chain
guides if you hold the chain in the middle of the
bar (Fig. 8).
– Using a screwdriver, make the chain run along
the guides to check it moves smoothly without
resistance.
ATTACHING THE PRUNER (Fig. 9)
– Pull out the stop pin (1) and push the rod (2) right
down until the stop pin (1) clicks into the hole (3)
in the rod. This is easier to do if you rotate the
bottom of the rod (2) slightly in both directions.
The pin (1) is in place when it is completely lo-
dged in the hole.
– Once inserted, tighten the knob (4) securely.
