Feed Rollers

The feed rollers rotate in bushing blocks that are spring-loaded. The feed rollers ride up on the board so roller pressure is maintained. If chips or sawdust build up between the bracket and bush- ing block, the amount of roller vertical travel will be reduced. See Figure 16.

Remove trapped sawdust from between the bushing block and the bracket

Figure 16. Location of potential trapped sawdust.

Periodically check and clean chips and sawdust from between the bushing blocks and brackets. Remove the side covers from the Planer by removing the depth-of-cut handle on top, and then remove the four Allen® head screws holding the cover. Lift the top cover off, then remove the sides. This provides easy access to depress the rollers so that chips and sawdust can be easily removed:

1.Place a 3-4'' high block of wood between one of the feed rollers and the planer bed. Ensure that the block of wood is not under the cutterhead.

2.Lower the cutterhead assembly down just enough so that the roller is pushed up against the spring and pressure is off of the two brackets.

3.Remove any trapped material from between the roller assembly and bracket.

4.Raise the cutterhead assembly and remove the block of wood.

5.Repeat Steps 1 through 4 for the other feed roller.

6.Replace the sides, cover and depth-of-cut handle.

Lubrication

There are two primary points requiring periodic lubrication; the head elevation screws and the feed roller chain drive. Access for lubrication requires removing the cover and sides of the machine first. Remove the depth-of-cut handle and the four Allen® head screws on the top cover. Pull the cover off and the sides are then free to be removed. See Figure 17.

The elevation screws on each side of the machine should be coated with a light grease to lubricate the threads. The chain drive can be lubricated with a spray oil. Saturate each chain link, then wipe off the excess so that sawdust will not be attracted.

Replace the sides, cover and handle when com- plete.
