Operation - Wen 4212 Manual

FEEDING THE DRILL BIT
• Pull down on the feed handles with only enough force to allow the drill bit to cut.
• Feeding too rapidly might stall motor, cause the belt to slip, damage the workpiece, or break the drill bit.
• Feeding too slowly will cause the drill bit to heat up and burn the workpiece.
MECHANICAL VARIABLE SPEED (FIG. 21)
This is a mechanical variable speed drill press. To increase or
decrease the speed when operating, raise or lower the speed
handle (Fig. 21 - 1).
Use the following table to determine the recommended speed
for the drill size you are using and the type of material you are
to drill. While drilling, check the speed on the digital speed
readout (Fig. 21 - 2) located at the front of the drill press.
WARNING:
Do not change speeds using the variable speed handle without turning on the machine.
