Maintenance

Disconnect machine from power source before performing any maintenance. Failure to comply may cause serious injury.

Check all screws and fasteners occasionally and keep them tightened securely.

Inspect cords; a cord that is frayed or damaged in any way should be replaced immediately.

The table and fence surfaces must be kept clean and free of rust for best results. Some users prefer a paste wax coating. 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 wax pickup does.

Lubrication

The cutterhead runs in two single-row sealed and shielded ball bearings, which are pre- lubricated for life - no maintenance is necessary.

Occasionally apply a good grade of light grease to areas of the jointer where friction may occur, such as when the tables are raised or lowered.

Cutterhead Repairs

The entire cutterhead assembly may be removed for bearing replacement or other cutterhead maintenance procedures. The procedure is identical for both helical and straight cutterheads.

To remove the cutterhead:

1.Disconnect machine from power source.

2.Remove rabbeting ledge and fence.

3.Lower infeed and outfeed tables until they are clear of the cutterhead.

4.Remove belts.

5.Remove the two hex cap screws and lock washers that hold the cutterhead to the bed

– these are accessed from the underside of the bearing blocks as shown in Figure 32.

Before removing cutterhead, wrap it with several cloths to prevent personal injury.
