8. Prior to fitting the chain drive side cover (22),
you need to ensure the chain tensioner pin (29)
will locate correctly in the guide bar (18). Before
fitting the chain drive side cover (22), rotate
the tool free chain tensioning dial (black)(21)
in an anti clockwise direction (Fig J) until the
tensioning pin (29) is fully to the right hand side
(Fig K).
9. Fit the chain drive side cover (22) over the two
threaded studs. The chain tensioner pin (29) will
now sit on the guide bar (19) and needs to be
moved to locate in the guide bar (18).
10. Applying a downward pressure with one hand
and support the black locking lever (23) so it
does not rotate. (Left hand in Fig L), rotate the
tool free chain tensioning dial (black)(21) in a
clockwise direction (Right hand in Fig L). The
chain tensioner pin (29) will move forward and
suddenly drop into the hole in the guide bar (18).
Ensure the chain drive side cover (22) has fully
dropped into position and is sitting on the bar.
11. Rotate the tool free locking dial/lever (23) in a
clockwise direction ensuring the chain drive side
cover (22) is being clamped to the chainsaw.
DO NOT fully tighten. Tighten only to the point
where the chain drive side cover (22) is just
holding the guide bar (18).
12. To tension the chain (19), hold the tool free
locking dial (23) with one hand so it does not
rotate, and then rotate the tool free tensioning
dial (black)(21) in a clockwise direction until the
chain has firmed up on the guide bar (18). The
chain (19) should be able to be lifted by approx
5mm (Fig M).
13. To complete the chain fitting task, fully tighten
the tool free locking dial (23) by rotating firmly
in a clockwise direction until secure, and then
slide the tool free locking lever (23) back to the
central position.
NOTE: the chain (19) should be able to rotate
around the guide bar (18) when assembled
correctly.
