THIS IS THE MOST IMPORTANT INFORMATION IN THIS MANUAL FOR
SUCCESSFUL HOLE CUTTING
1. Make sure cutter is properly installed. (See instructions for installing
Rotabroach® Cutter in arbor.)
2. The #1 cause of premature cutter failure is improper clamping. Read,
understand and follow clamping procedures on the next page.
3. Always use caution in contacting the rail with the cutting tool. Allow the
cutter to completely enter the rail before applying full feed pressure.
4. Do not force tool at the end of cut. Reduce manual feed pressure prior to
break-through on the rail and allow the cutter to work.
The Hougen 10923A and 10924A Electric Rail Drill in conjunction with the
Rotabroach® cutting tool provides you with the most efficient lightweight
rail drilling system available. This new cutting technology will be most successful
when the operator understands the above mentioned instructions.
ATTENTION: NEW CLAMPING PROCEDURE
WARNING: IMPROPER CLAMPING WILL
CAUSE PREMATURE CUTTER FAILURE!
WITH CLAMP IN OPEN POSITION, REST
UNIT ON RAIL BASE. BOTTOM OF SHOES
SHOULD CONTACT TAPER ON RAIL BASE.

PERFORMANCE TIP: CLOSE CLAMP UNTIL CLAMP PAD CONTACTS
WEB OF RAIL.
STEP #2:
RAISE REAR OF RAIL DRILL TO LOCATE
SHOES IN PROPER POSITION.
STEP #3:
WHILE MAINTAINING CONTACT BETWEEN
SHOES AND RAIL, TIGHTEN CLAMP.
STEP #4:
WHEN UNIT IS FIRMLY CLAMPED, CHECK
FOR PROPER SHOE AND PAD CONTACT ON
BOTH SIDES.

IMPORTANT SAFETY INSTRUCTIONS
WARNING: When using electric tools, basic safety precautions should always be
followed to reduce the risk of lire, electric shock, and personal injury, including the
following:
1. READ ALL INSTRUCTIONS
2. Grounding Instructions
This tool should be grounded while in use to protect the operator from electric
shock.
•The tool is equipped with a 3-conductor cord and 3-prong grounding type
plug to fit the proper grounding type receptacle. The green (or green and
yellow) conductor in the cord is the grounding wire.
Never connect the green (or green and yellow) wire to a live terminal. Your unit is
for use on 115 it has a plug that looks like that shown in sketch. An adapter see
sketches, is available for connecting sketch type plugs to 2-prong receptacles.
•The green-colored rigid ear, lug, or the like, extending from the adapter
must be connected to a permanent ground, such as a properly grounded
outlet box.
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 the conductor size is large enough to prevent excessive voltage
drop which will cause loss of power and possible
motor damage.
Keep Work Area Clean
Cluttered areas and benches invite injuries. Keep dirt
and chips from under Rotabroach Gutter area and drill
shoe.

Consider Work Area Environment
Do not expose tool to rain.
Do not use tool in damp or wet locations.
Keep work area well lit.
Do not use tool in presence of flammable liquids or gases.
Guard Against Electric Shock
Prevent body contact with grounded surfaces. For example: pipes, radiators, ranges,
refrigerator enclosures.
Keep Others Away
Do not let visitors contact tool or extension cord. All visitors should be kept away
from work area.
Store Idle Tools
When not in use tools should be stored in a dry, and high Or locked-up piece out
of reach of children.
Do Not Force Tool
It will do the job better and safer at the rate for which it was intended.
Use Right Tool
Do not force small tool or attachment to do the job of a heavy-duty tool.
Do not use tool for purpose not intended —for example - do not use circular saw
for cutting tree limbs or logs.
Dress Properly
Do not wear loose clothing or jewelry. They might entangle with spinning chips
or get caught in moving parts. Rubber gloves and non-skid footwear are
recommended when working outdoors. Wear sturdy leather work gloves when
working indoors.

Always Wear Safety Glasses or Goggles
Do Not Abuse Cord
Never carry tool by cord or yank it to disconnect from - receptacle. Keep cord from
heat, oil and sharp edges.
Secure Work
Clamp work securely using appropriate shoe size and shape. Tighten clamp by
using two hands with handle placed in central position and tighten securely.
Do Not Overreach
Keep proper looting and balance at all times.
Maintain Tools with Care
Keep tools sharp and clean for better and safer performance. Do not use dull or
broken Rotabroach Cutters.
Follow instructions for lubricating and changing accessories.
Inspect tool cords periodically and, if damaged, have repaired by authorized
service facility.
Inspect extension cords periodically and replace if damaged.
Keep handles dry, clean, and free from oil and grease.
Disconnect Tools
When not in use, before servicing, and when changing Rotabroach Cutters or
accessories.
Remove Adjusting Keys and Wrenches
Form habit of checking to see that keys and wrenches are removed from tool
before turning it on.

Outdoor Use Extension Cords
When tool is used outdoors; use only extension cords intended for use outdoors
and so marked.
Stay Alert
Watch what you are doing. Use common sense. Do not operate tool when you
are tired.
Check Damaged Parts
Before further use of the tool, a part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended function.
•Check for alignment of moving parts, binding of moving parts, breakage of
parts, mounting, and any other conditions that may affect its operation.
A part that is damaged should be properly repaired or replaced by an authorized
service center unless -otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced by authorized service center.
Do not use tool if switch does not turn it on and off.
Additional Safety Precautions
Arbor and cutter should never be used as a hand-hold.
Keep hands and clothing away from all moving parts.
Do not use Rotabroach Cutters where ejected slug might cause injury (slug ejected
at end of cut).
Be sure that all safety devices are properly adjusted and in use. Also, adhere to
all operating instructions.

Do not drill through any surface that may contain live electrical wiring. Drilling into
a live wire could cause exposed metal parts of the drill to be made live.
Do not attach Rail Drill to live 3rd rail track
Remove chips wrapped around Rotabroach Cutter and arbor after each hole. With
motor off and power disconnected, grasp chips with leather gloved hand and pull
and rotate counterclockwise.
Should the cutter become jammed in the work, stop the unit immediately to
prevent personal injury.
Disconnect the tool from the power supply and loosen jammed cutter by turning
the arbor counterclockwise. Never attempt to free the jammed cutter by starting
the motor.
Never operate the tool without culling fluid being applied to the inducer 0-rings or
without the inducer ring retaining finger in place.
Operating Near Welding Equipment
When operating your Rail Drill near an arc welder, it is important that they are
connected to the same Earth Ground. If they are not, severe damage to the unit,
particularly the power cord, could occur. This could also result in personal injury to
the operator.
Safe Electrical Connection
Wet electrical connections are shock hazards. To
prevent the cutting fluid from traveling along the cord
and contacting the plug or power outlet, tie a drip loop
as shown.
•Also elevate extension cords or gang box
connections.
