Delta Essential Maintenance for Your Planer: Brush Inspection and Lubrication Tips

BRUSH INSPECTION AND

REPLACEMENT

Disconnect tool from power source

Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after a new set of brushes has been installed. After the first check, examine them after about 10 hours of use until such time that replacement is necessary.

The brush holders, one of which is shown at (A) Fig. 27, are located on the motor housing opposite each other. One of the brushes, removed for inspection, is illustrated in Fig. 28. When the carbon (B) on either brush is worn to 3/16" in length or if either spring (C) or shunt wire is burned or damaged in any way, replace both brushes. If the brushes are found serviceable after removing, re- install them in the same position as removed.

After brush maintenance is completed, the cutterhead guard must be re-installed before starting the planer.

LUBRICATION

The gears in the gear box and the feed roller bushings should be lubricated periodically.

1.Remove the screw (A) Fig. 29, and nut located on the other end of screw. Remove the side cover (B) from the left side of the planer.

2.Place a light coat of E.P. multi-purpose grease on the teeth of the gears (C) Fig. 30, and a light coat of spray lubricant on the chains (F). Replace the side cover.

3.Place the planer on its back and squirt oil on the feed roller bushings (D) Fig. 31 at each end of the feed rollers (E).
