User manual DAHON REAR DERAILLEUR

[. . . ] » While turning the crank, push the rear derailleur inboard by hand to the largest cog. [. . . ] » Rotate the rear shifter to the largest number and gear indication tab/dash line up. » Turn the rear shifter barrel adjust clockwise fully into the shifter, then back it off 1 full turn. » Feed the rear shifter cable through the rear derailleur cable housing, stops and cable guides. Turn the limit screw marked 'H' on the outer link of the derailleur to align the upper guide pulley center with the outboard edge of the smallest cog. Setting the chain gap at this point of your installation may be considered a rough estimate. Precision index shifting may require small changes of the b-adjustment while setting the proper cable tension. » It is best to measure the rear piece of cable housing between the frame and rear derailleur after the chain gap is determined. » Do not use the b-adjust screw to adjust the rear derailleur to act as a chain-tensioning device or to prevent chain suck. [. . . ] Relubricate ­ while turning the crankset ­ both pulleys by spraying some lube between the dust cover and the shoulder of the pulley. [. . . ]
