8.2 Chain tensioning (540 RPM):
Over the lifetime of the machine, the drive chains will extend slightly over time. To combat
this issue as per the image above, all KEENAN machines are fitted with chain tensioners on
the slack side of the chain.
Primary chain : This preload tension can be set by loosening the locknut and adjusting the
upper spring seat. The correct tension will be applied to the chain when the compression
spring is compressed to 165 mm, as shown below.

Rotor and auger chain: This preload tension can be set by loosening the locknut and
adjusting the spring seat. The correct tension will be applied to the chain when the
compression springs are compressed to 250 mm, as shown below.

CAUTION:
For the first month of ownership (i.e., during the chain bedding-in period), it is
recommended to check chain tension daily (see next section).
