The variable speed pulleys and the speed range shifter mechanism should be oiled weekly with a few drops of light
machine oil in the two oil holes (A) Fig. 38, located on top of the variable speed pulleys and the hole (B) located on top
of the shifter mechanism.
IMPORTANT: Oil the holes when the drill press is turned OFF. Then turn the machine ON and run through the
low and high speed ranges a few times.
