Rabbeting rabbet removal of the guard. Use extreme caution and keep hands clear of cutterhead. Always re-install guard immediately after rabbeting operation is completed. A rabbet is a groove cut along the edge of a board. See Figure 42. The width and thickness of the wood to be rabbeted depends upon the width and length of the rabbet. -
Page 27: Direction Of Grain
Although the fence may be tilted in or out for a bevel cut, it is recommended for safety reasons that the fence be tilted in toward the operator, making a cradled cut. Direction of Grain Avoid feeding work into the jointer against the grain. -
Page 28: Maintenance
Maintenance Disconnect machine from power source before maintenance. Failure to comply may cause serious injury. The table and fence surfaces must be kept clean and free of rust for best results. Some users apply a thin coat of paste wax. Avoid waxes or protective sprays that contain silicone, as this can transfer to the workpiece and make it difficult for later finishes to adhere to the wood. -
Page 29: Cutterhead Repairs
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.
