OPERATION

WARNING!

To  reduce  the  risk  of  injury,  wear  safety  goggles  or  glasses

with  side  shields.

Typical  Operation

1. Check the work surface to make sure it is clean and free of foreign

materials.
Paint, rust, scale or uneven surfaces decrease the holding strength

of the magnet. Chips, burrs, dirt and other foreign materials on the

surface of the magnetic base will also decrease holding power. Use

a smooth, flat file to keep the magnet clean and free of nicks.
The electromagnetic drill press attaches magnetically to 3/8" or thicker

ferrous  stock.  Do  not  use  on  stock  less  than  3/8".  The  magnetic

base WILL NOT hold on nonmagnetic grades of stainless steel.

2. To install/remove cutter:

4. Move the spindle up so the cutter and center pin are above the work

surface.

   •

Do  not  use  cutting  fluid  in  an  overhead  or  any  other  posi-

tion  that  allows  cutting  fluid  to  enter  motor  or  switch

enclosure.

   •

Wet  connections  are  shock  hazards.  Prevent  cutting  fluid

from  traveling  along  cord  and  contacting  the  outlet,  ex-

tension  cord  connections  or  tool  plug.  Each  time  tool  is

plugged  in,  elevate  extension  cord  or  gang  box  connec-

tions  and  arrange  a  drip  loop  (See  Fig.  6).  If  plug  or  con-

nections  get  wet,  turn  power  off  to  outlet  before

unplugging  tool.

Fig. 6

WARNING!

A.

Raise the drill motor to its highest position. Tighten stop knob.

B.

Insert cutter into drill spindle with the two (2) flats of the cutter

aligned with set screws. Make sure the center pin is inserted

into the cutter.

NOTE: 

Cutter should be fully seated into drill spindle.

C.

Tighten  set  screws  with  3/16"  hex  key  provided.

D.

Loosen the stop knob.

E.

Reverse procedure to remove cutter.

NOTE:

 Do not remove cutter unless slug is removed. Slug may

eject  unexpectedly.

Avoid contact with cutter tips. Periodically inspect the cutter tips for

loose or damaged tips.

3. Plug in tool to power source.

5. Position the tool so the center pin is directly over the desired cutting

location. Push the magnet switch to the “ON” position. The magnet

indicator light will turn on.

The cutting fluid reservoir will empty as the center pin contacts the

work  surface.  When  notching  or  slotting,  it  is  required  to  spray

cutting fluid directly to the cutter and work piece with the supplied

hand  pump.  Keep  hand  pump  away  from  moving  parts.  Failure  to

use the lubricant properly will cause cutter damage.
The use of HAWG WASH®  cutting fluid is recommended for long life

of these cutters. The operator is responsible for the application of

lubricants other than HAWG WASH® cutting fluid.
In  overhead  or  vertical  cutting  applications,  do  not  use  cutting

fluids. Use only lubricant pastes or sprays recommended for high speed

cutting. Do not allow lubricant pastes and sprays to enter tool.

Fig. 8

7. With the drill on/off switch  in the "OFF" position, fill the cutting fluid

reservoir  with  cutting  fluid  through  the  slots  in  the  drill  spindle

(Fig. 8).

C-clamp

To  reduce  the  risk  of  injury,  do  not  hold  workpiece  by  hand.

WARNING!

6. Use a safety strap on vertical or overhead situations (Fig. 7).

A.

Route the safety strap, ring side first, through the lower slot,

and  wrap  it  tightly  around  a  solid,  rigid  structure  as  shown.

Make sure the strap is not twisted.

B.

Hook  the  safety  strap  snaphook  provided  to  the  ring.

Eliminate any slack in the strap.

C.

When using on a vertical surface, secure the safety strap

with a c-clamp or similar device. This will hold the strap in

place and prevent the tool from sliding down  the  vertical

surface.

NOTE

: Do not clamp to the strap. This may damage the strap

and cause it to break (Fig. 7).

To  reduce  the  risk  of  injury,  always  use  a  safety  strap  when

drilling  overhead  or  on  a  vertical  surface.
