TO CHECK BELT TENSION:

Squeeze the V-Belts at their midpoints with moderate finger pressure. You should be able to deflect each V-Belt about 3/4". Belts will rarely be too tight, but will sometimes be too loose.

To adjust belt tension:

1.Remove the belt guard using the two threaded knobs. Remove the panel at the back of the machine stand to gain access to the motor assembly.

2.The motor pivots on a platform which is suspended at one end by a threaded adjustment bolt. Adjust the two locknuts up or down the shaft until the desired belt deflection is achieved. See Figure 32.

3.Tighten the bolts against the pivot plate to lock the motor adjustment into place.

4.Check belt tension again. Repeat steps 2-3 as necessary.

Gearbox

The gearbox is located just behind the handwheel on the right side of the planer. The gearbox transfers power from the belt-driven cutterhead to the power feed rollers. The two-speed transmission is controlled by a push/pull lever on the right side of the planer. When engaged, the power feed rollers will move lumber through the planer at either 16 or 20 feet-per-minute. The center lever position is neutral.

TO INSPECT THE GEARBOX:

1.Loosen the socket head cap screw on the gearbox cover. Gently pull the cover off the roll pins that hold it in place.

2.Check the bolts holding the sprockets in place. Inspect the drive chains to ensure that the retaining clips are in place. Replace the clips if necessary. See Figure 33.

Move these nuts to adjust belt tension.

DO NOT make adjustments while the planer is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply could result in serious injury.
