Knives
(Model G9953 Only)
Using sharp knives is one of the most important factors involved with the operation of the jointer. A good maintenance procedure is to hone the knives to keep them in top shape. A knife hone will polish and finely sharpen jointer knives quick- ly and easily without removing them.
For damaged or extra dull knives, have them resharpened by a professional grinder. To avoid downtime from resharpening, we recommend having an extra set of knives on hand.
Carbide Cutters
(Models G9953ZX, G9953ZXF and G4815)
The carbide cutters are typically rotated at the same time when they become dull; however, the cutters can also be rotated individually when one becomes nicked or damaged. Refer to Section 8: Service Adjustments for instructions on rotating or replacing the carbide cutters.
Lubrication
Most of the ball bearings are permanently sealed and lubricated so they will require no attention until they need to be replaced. The following loca- tions should be lubricated after approximately 80 hours of continuous use.

The cutterhead has two bearings that require grease. There are white stickers with arrows pointing to their general location. There are two grease
Handwheels
Each handwheel is lubricated via an oil cup locat- ed just behind the handwheel body, on the axle collar. Remove the handwheel lock knob and slide the handwheel off the axle. This will reveal the oil cup. Apply a small amount of light machine oil.
Table Elevation Mechanism
The table elevation screw and gear mechanism for each handwheel can be accessed by remov- ing the left and right rear base housings. Apply a generous amount of grease to the elevation screws and gears.
