Cleaning
Lubrication
Moving parts, such as chains, should be lubricated peri-
odically with a light machine oil. Motor bearings need no
lubrication.
Pillow Bearing: Must be lubricated every 20 hours of
operation. Use a high-quality, lithium-based grease. A
grease fitting (Figure 32) is located on the top of each
pillow bearing. Give only one to two pumps of the grease
gun. Too much grease can pop seals out.
Gearbox: Change the oil in the gearbox every 500 hours
with new 80-90W automotive grade gear oil.
1. Remove the variable speed knob, the hex nut,
knurled collar, and the four button head screws
securing the feed motor cover (see
Figure 33).
