Feed Rollers
The feed rollers rotate in bushing blocks that are spring loaded. The feed rollers ride up on the board so that the roller pressure is maintained. If chips or sawdust build up between the bracket and bushing block, the amount of roller vertical travel will be reduced, potentially causing improp- er feeding of lumber through the machine (Figure 26).

Periodically check and clean chips and sawdust | |
from between the bushing blocks and brackets. | |
Remove the elevation handle, the top covers, and | |
the sides. This provides easy access to depress | |
the rollers so that chips and sawdust can be easily | |
removed. |

To clean the feed rollers: |
|
1.DISCONNECT PLANER FROM POWER!
2.Place a 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.
3.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.
4.Remove any trapped material from between the roller assembly and bracket.
5.Raise the cutterhead assembly and remove the block of wood.
6.Repeat Steps
7.Replace the sides, top plates, and elevation handle.
Lubrication
There are two primary points that require peri- odic
Elevation Screw
Chain
Elevation Screw
Figure 27. Lubrication points of chain and elevation screws.
The elevation screws on each side of the machine should be coated with a light multi-purpose 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.
