12. Rotate the chain (19) a few times to ensure the
chain (19) is free to rotate the drive sprocket
(28) and is correctly engaged on the sprocket.
Check the tension of the chain. The chain
should be fully seated in the bar channel. DO
NOT over tighten. The chain (19) should be
able to be lifted at least 5mm in the centre of
the bar. (Fig L)
13. Using the supplied spark plug / screwdriver
wrench (32), firmly tighten the chain drive side
cover nut/s (23) on the chain drive side cover
(22) in a clockwise direction. (Fig M)
CAUTION: A new chain (19) will stretch
after just a few minutes of use. Check and,
if necessary, re-adjust the chain tensioning
screw (21). A loose chain causes rapid wear to
both the chain (19) and the guide bar (18) and
could derail causing a major safety hazard.
NOTE: Do not make ANY adjustments with the chainsaw engine running.
To tighten a loose chain (19), loosen the chain drive side cover lock nuts (23),
then using the supplied screwdriver (33), turn the chain tensioning screw
(21) clockwise to tighten the chain (19).
Do not over tighten, the chain (19) should be able to lift 5 mm from the
middle of the bar.
Retighten the chain drive side cover nuts (23) firmly using the supplied spark
plug / screwdriver wrench (32).
Run the chainsaw for approximately 30 sec and then turn the chainsaw off.
Retest the chain.
