The Model G0477 features two ribbed belts, shown in Figure 26, that are generally good for the life of the machine. However, there are some instances where these belts must be replaced.

Figure 26. Drive and fan belts.

To change the drive and fan belts:

1.DISCONNECT THE MACHINE FROM THE POWER SOURCE!

2.Unscrew and remove the cap screw that holds the crank handle in place, and remove the crank handle.

3.Remove the four set screws that hold the housing caps in place.

4.Remove the right housing cap, feed rollers, preset depth gauge knob, and right housing cover.

5.Roll the fan belt off the pulleys.

6.Loosen the motor tension cap screw indi- cated in Figure 26 to lower the motor and to put slack on the drive belt.

7.Roll the drive belt off the cutterhead pulley.

8.Lift the drive belt off the motor pulley and slide it through the space between the pulley and the headstock casting to free it from the machine.

9.Repeat Steps 5, 7 and 8 in reverse order to install new fan and drive belts.

10.Once both belts have been installed, have an assistant lift the motor slightly to place tension on the drive belt, and tighten the cap screw loosened in Step 6. Both belts should now have a displacement or "give" of around 1⁄4" on each side.

Chain Tension and Headstock Leveling

Tools Needed:	Qty
Hex Wrench 4mm	.............................................. 1

If the headstock slips out of alignment with the table, the planer/moulder will produce an uneven cut. Often this is due to the chain losing tension over time. Follow these steps to correct head- stock misalignment and to correct chain slack.

To correct a misaligned headstock:

1.DISCONNECT THE PLANER FROM THE POWER SOURCE!

2.Place even-sized shims under each corner of the headstock and lower it until the head- stock rests on at least one of the shims.

3.If there is a gap between the headstock and any shim(s), proceed to the next step. If there is no gap, the headstock needs no adjustment.

4.Loosen, but do not remove, the two cap screws shown in Figure 27 and slide the idler bracket so the chain loosens slightly.
