INSTALL THE CHAIN
1
Fitting the Chain:
Wrap the chain around the idler pulley (1) and drive
sprocket (as illustrated in fig 1), ensuring the chain passes
through the trolley assembly (3).
NOTE: Locate the chain connector as illustrated above
approximately 300mm from the Idler pulley.
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.
Tighten the Chain
Once the chain has been installed, join the two
ends together using the connector. Tighten the
connector until the chain has no slack.
DO NOT OVER TIGHTEN!
Once the chain has been tensioned, tighten the
lock nuts.
NOTE: Use the tube of grease provided to
lubricate the chain and sprocket.
