ensuring the chain passes through the trolley assembly (3).
NOTE: Locate the chain connector (2) as illustrated above approximately 300mm from the Idler
pulley.
Tighten the chain:
Once the chain has been installed, join the two
ends together using the connector. Rotate the
adjuster until the chain has no slack.

Additional Step for 2750mm Pole
All Chain kits supplied are for 3000mm poles. You will need
to remove the pre-measured section of chain for use with the
2750mm pole option.
Locate the two removable links and remove the section of
chain between them. Once the section of chain has been
removed use one of the joiners to re-join the shortened
chain assembly.
