will not allow full metal to metal contact. If the magnet fails to hold
on a metal surface, it may be due to this condition and a check can
be made with a feeler gauge or similar device in order to determine
if an air gap exists under the magnet at the crucial points.
1. Place drill press on work surface so that drill point or cutter pilot
is directly over spot to be drilled. Pull trigger and twist control
handle counterclockwise until MAG-ON light glows, indicating the
magnet is energized. Figure 1. When drilling in an overhead or
vertical position, the safety chain must be employed. See Figure
2A & 2B for two suggested positions. The use of a clamp between
the chain loops as shown in
Figure 2B will prevent the mag press from falling when in the de-
mag operation. (Clamp not included).
2. (DW154, DW156) The motor switch is now aligned with a slot in
the control handle, allowing the motor switch to be activated.
Make sure reversing ring on top of motor is in the forward position.
Figure 3. (On DW157 make sure reversing switch is in forward
position).
3. Gently apply pressure to feed handle until twist drill or cutter has
a full bite (see special instructions for DW154) then apply steady
pressure until cut is complete.
NOTE: The feed handle is quickly and easily reversible. Depress
button in feed handle hub and remove handle. Insert in opposite
side and release button. Figure 4.
4. Turn off motor and allow motor to run down before turning magnet
off.
5. Turn magnet off by depressing trigger and turning control handle
clockwise 45°. Figure 5.
6. After each use, rock unit back onto handle guard and remove all
chips from magnet surface.
