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.
