4.0 - OPERATING INSTRUCTION
4.1 – CHAIN LENGTH
To determine Drive chain length required see Table 1 that shows the chain length for various diameters of
pipe. For diameters of pipe, other than those listed, see the calculation formula on our web site at
4.2 – HOW TO LENGTHEN OR SHORTEN THE DRIVE CHAIN
From Table 1 select the drive-chain length required. If the chain length is incorrect, proceed as follow:
