Page 29

Knives can usually be whetted several times in the cutterhead before having to be removed and re-ground.

TIP: If the jointer is used frequently, keeping a spare set of knives on hand is recommended. Extra knives (stock no. 6296046, set of 3) may be obtained from your distributor, or by calling customer service at 1-800-274-6848.

Cutterhead Repairs

The entire cutterhead assembly may be removed from the Jointer for bearing replacement or other maintenance procedures.

Use caution when working around sharp knives.

To remove the cutterhead, proceed as follows:

1.Disconnect jointer from power source.

2.Remove fence assembly from jointer.

3.Lower both infeed and outfeed table.

4.Remove belt guard, and remove drive belt from around cutterhead pulley.

5.Remove knives from cutterhead.

6.Remove rabbeting ledge by loosening and removing the two hex cap screws and washers which secure it to the infeed table.

7.Loosen the two bolts that secure the cutterhead to the base; these are accessed through the gap below the jointer base. See Figures 49 and 50. Place a wrench on each of the bolt heads and turn each bolt until the cutterhead is loosened.

8.Lift cutterhead straight up from base.

9.Remove pulley and both bearing housings.

IMPORTANT: If the bearings need replacement, this should be done by qualified service personnel. Bearings are press fitted and must be removed or installed with an “arbor press”.

10.To re-install cutterhead, reverse the above procedure. Before re-installing, make sure the machine's curved seats of the base casting are free of dirt, dust or grease, to help ensure a tight fit.

11.After the cutterhead has been installed, check the infeed and outfeed table settings in relationship to the cutterhead.

TIP: You may wish to keep an extra cutterhead on hand to maintain shop productivity.
