Tensioning Height
Chain
The height chain transfers movement from the
headstock height handwheel to the columns that
control headstock height. The chain drive can be
adjusted to remove slack if the chain stretches
over time.
Note: You must first unbolt and raise planer off of
stand/workbench with a forklift or other suitable
lifting device (see Page 17) before proceeding.

Figure 49. Belt deflection when V-belts are
correctly tensioned.
6. After V-belts are correctly tensioned, tighten
belt tension jam nut and motor mount screws,
then re-install belt covers.
5. To adjust V-belt tension, rotate belt ten-
sion adjustment bolt (see Figure 48) to
raise or lower motor until belts are correctly
tensioned.
Note: V-belts are correctly tensioned when
there is approximately
3
⁄8" deflection when
moderate pressure is applied to them midway
between pulleys, as illustrated in Figure 49.

be very difficult to return chain to its proper
location on sprockets without changing
table adjustments.
3. Clean and lubricate chain and sprockets
(refer to Height Chain & Sprockets on
