WARNING!
Improperly connecting the grounding wire can result in the risk of electrical shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug provided with tool. Never remove the
grounding prong from the plug. If the cord or plug is damaged, have it repaired
before using. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician. The BM-20 must be plugged into an appropriate outlet,
properly installed and grounded in accordance with all codes and ordinances.
The plug and outlet should look like those in Figure A.
WARNING!
DO NOT USE SLUGGER DRILLING MACHINES ON SURFACES OR MATERIALS BEING
WELDED. DOING SO CAN RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE
SLUGGER DRILLING MACHINE.
GROUNDING INSTRUCTIONS
6
DRIP LOOP: To help prevent cutting fluids from traveling
along power cord and contacting power source, tie a drip
loop in power cord as shown in Figure B.
Fig. B
Use only 3-wire extension cords that have 3- prong grounding-type plugs and 3-pole receptacles that accept the tool’s
plug. Replace or repair damaged cords. Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. Jancy recommends using a minimum 12 gauge extension cord
not to exceed 100 feet. The table below is supplied only as a guide to minimum gauge for extension cords, where the
smaller the gauge number, the heavier the cord.

GETTING STARTED
CAUTION!
ALWAYS DISCONNECT BM-20 FROM POWER SOURCE BEFORE MAKING ADJUSTMENTS.
The BM-20 beveling machine comes ready to use with 12 BMJBEV1 inserts mounted in the milling head. However, before
you begin to bevel, the following must be determined (this information will affect the rate of feed, finish of bevel and life
of the inserts):
1. Angle of bevel
2. Desired width of bevel (depth)
3. Material to be beveled
4. Condition of material to be beveled (has material been work hardened?)
7
ADJUSTING THE BEVEL ANGLE
Locate four fasteners (item #14) on milling head housing side wall. Loosen fasteners with supplied wrench and then
move the guide assembly to desired bevel angle. Confirm angle by aligning graduates located on side of milling head
housing. After setting bevel angle, secure guide assembly by tightening fasteners (item #14).
ADJUSTING THE WIDTH OF THE BEVEL ANGLE
Locate two lever handles (item #11) on milling head housing side walls. The width of bevel can now be adjusted rotating
adjustment knob (item #6). A clockwise rotation decreases bevel width (depth of cut) while counterclockwise increases bevel
width (depth of cut). After adjusting, secure by tightening handles (item #11). Maximum bevel width should not exceed 3/4".*
*Maximum bevel width will require multiple passes depending on hardness of the material.

BEVELER INSERTS
The BM-20 milling spindle is equipped with two milling head insert rings, each holding six BMJBEV1 cermet inserts, for
a total of 12 inserts. The operator should routinely inspect the inserts for excessive wear or damage. Excessive machine
vibration or poor bevel finish may indicate the inserts should be rotated or replaced. Before replacing inserts, make sure
that all four edges of each insert have been used. When rotating inserts, all 12 inserts should be rotated at the same time
to eliminate the possibility of chatter on the work piece.
CHANGING THE BEVELER INSERTS
With machine disconnected from power source, remove milling head housing (item #7) by removing two handles located
on side of milling head housing sides (item #11). With milling head spindle and inserts exposed, remove each insert
using supplied 3mm allen wrench by loosening screw (item #27) holding each insert. At this point, the insert rings should
be clean and free of debris. When placing the inserts into the insert ring, be sure that each insert is pushed as far back
into the pocket as possible. NOTE: Using a feeler gauge, inserts must be set .004 inches from opposite insert ring shoulder.
Each insert should be snugged with provided 3mm hex driver and then torqued to 65 inch pounds with the provided
preset torque wrench. When torque wrench reaches 65 inch pounds, it will click. Stop immediately after hearing a click.
Each additional click will tighten the screws unnecessarily. NOTE: Use anti-seize lubricant on set screws for easy removal.
CAUTION!
WHEN REMOVING OR INSTALLING INSERTS, USE CAUTION TO PROTECT HANDS FROM CHIPS AND SHARP EDGES.
MAKING THE BEVEL CUT
Connect the BM-20 to grounded power source. If using an extension cord, check voltage at cord ends to ensure you
will not be operating the BM-20 on a voltage drop. Route power cord so that it will not interfere with the operator or
workpiece. Place the BM-20 on horizontal slide at the right edge of the work surface. Do not touch the milling head to
the edge to be cut at this time. Move rocker switch located on control panel to the lit position. Start the BM-20 by
depressing the push button switch marked “I”. To stop the BM-20, simply depress the push button “O”. Place right hand
on loop handle and left hand on front guide handle. Using right side of guide as a fulcrum, slowly pivot left side into
workpiece until entire guide is flush with the material to be beveled. Slide the BM-20 slowly to the left. The direction of
feed is marked on the milling head housing. NOTE: Remember the rate of feed is determined by the width of cut and
the material being beveled.
If the operator attempts to bevel too fast or too much material, the built-in overload indicator (item #35) will begin to
illuminate. Reduce the feed pressure at this time. If the motor load is not reduced, the machine will shut off to protect the
motor. If this occurs, move the BM-20 away from the beveled edge before attempting to restart.
Restart the BM-20 by depressing “O” (item #41). Wait 30 seconds and depress the “I” (item #41). NOTE: Continuous
operation with the overload indicator illuminated may cause permanent motor damage. The BM-20 is designed to operate
under normal conditions for one hour. To maintain the motor, allow a 15 minute cool down period after each one hour
duration of use. Simply shut off and disconnect the machine from power source.

2. Inspect control panel, switches and power cord to insure proper electrical operation.
3. Clean BM-20 occasionally with clean rag and mild cleaning solvent to maintain appearance and operation.
BEVELING PIPES
Roller attachment (part #309 to #319) allows you to bevel pipes and curves with the BM-20.
1. To prepare the machine for work on pipes, remove part #307. Slide it off the machine and replace it with the pipe
attachment (part #309 to #315).
2. Move the housing (part #205) to the “zero width of cut” position (refer to the section in the manual entitled,
“Adjusting Bevel Angle”).
3. Place machine on the edge of pipe in such a way that the milling tool touches the workpiece, and then fasten both
rollers. You can now adjust machine to the desired beveled angle. note: Do not use the BM-20 on pipes under
6-1/4" in diameter.
