Maintenance

Disconnect machine from power source before doing any 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.

Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week; this will fill casting pores and form a moisture barrier. This method provides a table top that is slick and allows rust rings to be easily wiped from the surface. Important also is the fact that talcum powder will not stain wood or mar finishes as some other products.

Gum and pitch which collect on the knives cause excessive friction as the work continues, resulting in overheating of the knives, less efficient cutting, and consequent reduction in the life of the knives. Use oven cleaner or “gum and pitch remover” to wipe this off the knives. Use caution when working around knives!

The bearings in the cutterhead are sealed for life and do not require lubrication.

The fence assembly should slide easily over the slide bracket. Keep the slide bracket, shown in Figure 48, lubricated with a good quality multi- purpose grease. Do not get grease on the drive belt.

Do not place heavy objects on the tables, or use the jointer as a storage table.

Sharpening Knives

Knives should be kept sharp. This will contribute to better stock finish, longer machine life, and safer operation.

A jointer knife hone provides a simple way to sharpen knives. Hones are available from many woodworking supply stores. Carefully read any instructions that accompany the hone.

Use caution and proceed slowly when sharpening knives. Disconnect jointer from power source, and wear approved eye protection.

When finished sharpening knives, they should be re-set level with and parallel to the outfeed table. See “Setting Knives at Correct Height and Parallel to Outfeed Table” on page 18.
