drilling vertically or overhead. Dip cutter in cutting paste for these
applications..
NOTE: This unit features an on-board lubrication system. To use
the lubrication system, remove the hose (F) from the bottle by
depressing the black collar (G) into the bottle. Remove the hose
from the bottom of the petcock. Remove the bottle from the
bracket and fill with cutting fluid. Replace bottle in bracket and
replace hose. Turn the petcock counterclockwise to start the fluid.
Turn the petcock clockwise to close the valve when the cut is
finished. The bearings are lubricated by the on-board system.
WARNING: Do not pour cutting fluid into the bottle while
mounted in the bracket. Do not allow cutting fluid to enter the
drill motor. Electric shock may result.
6. Start motor by pressing the green button.
7. Bring cutter lightly to the surface to be cut allowing 25-30
revolutions, bringing up light chip so that cutter has established an
external groove. This will position you properly. Apply steady
pressure through the entire cut. It is more important to keep rpms
up than to apply excessive force, causing cutter to slow motor
down. This will attain better cutting action, better cutter life, and
cleaner holes.
8. Slug should be expelled on the down stroke. If not, it will be
expelled automatically when motor is returned to the extreme up
position.
CAUTION: Gloves should be worn when handling slugs to avoid
injury to the hand by hot surfaces or sharp edges.

1. Place unit on work surface sot that the point is near the center of
the hole to be drilled.
2. Push the red button to turn power on.
3. Push the yellow button to activate magnet.

4. Turn lever (H) counterclockwise to loosen the
swivel base.
5. Move the drill and rotate about the magnet
until the pilot pin is directly above the center
of the hole to be drilled.
6. Turn lever clockwise to tighten the swivel.
Operation of the Forward/Reverse
Feature (DW159)
The forward/reverse switch is a collar (I) on the top of the drill unit of
the DW159 only.
Control
Apply sufficient pressure to achieve a smooth, progressive cut. Do
not force unit. If magnet starts to lift from work plate, decrease
pressure slightly and it will reclamp. Drill point pressure may exceed
holding power under one or more of the following conditions:
1. Excessive air gap—1/64"(.4mm) or more.
2. Thin metal (under 3/8"(10mm) depending upon position and
condition of metal surface.)
3. Metal with low magnetic properties.
4. Uneven or rough surface.
