The chain should be fully seated in the bar
channel. DO NOT over tighten. The chain (20)
should be able to be lifted at least 5mm in the
centre of the bar (Fig M).
12. Tighten the chain drive side cover nuts (24)
firmly using the supplied combination tool
(bar nut tube spanner) (33) (Fig N).
CAUTION: A new chain (20) will stretch
after just a few minutes of use. Check and, if
necessary, re-adjust the chain tensioning screw
(22).
A loose chain causes rapid wear to both the
chain (20) and the guide bar (19) and could
derail causing a major safety hazard.
NOTE: Do not make ANY adjustments with the
chainsaw engine running.
13. To tighten a loose chain (20), loosen the chain
drive side cover lock nuts (24), then using the supplied combination
tool (flat blade screwdriver) (33), turn the chain tensioning screw (22)
clockwise to tighten the chain (20) (Fig H). Do not over tighten, the chain
(20) should be able to lift 5mm from the middle of the bar.
14. Retighten the chain drive side cover nuts (24) firmly using the supplied
combination tool (flat blade screwdriver) (33) (Fig N). Run the chainsaw
for approximately 30 seconds and then turn the chainsaw off.
Retest the chain.
