If the drive chain tensioner rubber foot (Figure 57)

wears and the drive chain becomes slack after long-term

machine use, the chain will have to be readjusted. The

chain should not be tight like a V-belt where there is

preload on a pulley and shaft.

The sprocket shafts on this machine must be free float-

ing with no chain tension against them. The chain should

have approximately 3-5mm (Figure 58) of hanging slack

to ensure that the shafts are not always tensioned.

However, the chain must still be tight enough so it does

not skip sprocket teeth.

To adjust the drive chain slack, do these steps:

1. DISCONNECT THE PLANER/MOULDER FROM POWER!

2. Raise the headstock until you have easy access to the

chain area.

3. Loosen the tension adjuster jam nut (Figure 59).

4. Use a 4mm hex wrench to adjust the tensioner until

there is 3-5mm of hanging slack (Figure 58).

5. Tighten the jam nut, and test the operation.
