AFETY
Be sure to read and follow these important safety instructions:
When using your RB32 MiniBrute, be sure to follow these important safety precautions:
1. Before operating the machine, check supply voltage and general conditions, i.e. cable/cord
damage. A machine with damaged cable must be returned or repaired prior to use.
2. Always use the safety strap in all drilling applications.
4. Since cutting tools can shatter, eye and head protection should be worn at all times.
5. After use, clean machine and cutters and keep in the case provided.
6. Store when not in use, in a dry environment.
7. Always provide a method of catching slug, where the ejected slug may cause injury (slug
ejects at end of cut).
8. Should the cutter jam in the work-piece, stop the machine immediately. Isolate the
machine at the main supply. Loosen the cutter by rotating the arbor. Do not attempt to free
cutter by starting and stopping the motor.
9. Always use the safety guard provided.
Electrical afety
1. Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify the
plug in any way.
2. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. If the tools should electrically malfunction or break-
down, grounding provides a low resistance path to carry electricity away from the user.
3. Never use the cord to carry the tools or pull the plug from an outlet. Replace damaged
cords immediately.
4. When operating a power tool outside, use an outdoor extension cord marked “W-A” or
“W”. These cords are rated for outdoor use and reduce the risk of electric shock. Minimal
gauge external cord should be 12/3.
5. Use the RB-32 with 110 A/C voltage only. Not for use with generators, welders or any dc
power source. Do not use on any surface where welding is taking place.
Personal afety
Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medication.
Do not wear loose clothing or jewelry. Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch or plugging in tools that have the
switch on invites accidents.
Remove adjusting keys before turning the tool on.
Do not overreach. eep proper footing and balance at all times.
Safety equipment (eye protection, dust mask, nonskid safety shoes, hard hat, hearing
protection) should be used for appropriate conditions.
Tool Use and Care
Use clamps or other practical ways to secure and support the work-piece to a stable
platform.
Do not force tool. Use the correct tool for the application.
Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool.
Store idle tools out of reach of children and other untrained persons.
Maintain tools with care. eep cutting tools sharp and clean.
Check for misalignment or binding of moving parts, breakage of parts and any other condi-
tion that may affect the tool’s operation. If damaged, have the tool serviced before using.
ervice
Tool service must be performed only by qualified personnel.
When servicing a tool, use only original replacement parts.
Use of unauthorized parts will void the warranty.
Use of unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.
Magnetic Drill afety
The drill’s magnetic adhesion depends on the thickness of the work-piece. 1/2” (13mm) is
the minimum thickness for safe operation. eep the magnet clean of metal chips and other
dirt and debris. These will seriously reduce the magnetic adhesion. The drill must be
operated on its own electrical outlet. Always use the supplied safety strap or chain. An
electrical overload can result in loss of adhesion.
CAUTION: The slug ejects at end of cut and is very hot.
WARNING: Do not attempt to drill a work-piece, which is thicker than the maximum cutting
depth of the cutter being used. Never exceed 1-3/8” (35mm) cutter diameter.
Maintenance and Troubleshooting
eep the drill press and the cord clean. In case of electrical or mechanical malfunction,
immediately switch off the tool and disconnect the plug. Excessive sparking generally
indicates the presence of dirt in the motor or worn out carbon brushes. Periodically check
brushes for wear and replace when they reach 1/4” (6mm). Also check that the machine is
well lubricated.
For all other service and maintenance, please contact a Champion® authorized service
center.

RB32 OPERATING IN TRUCTION
Operating Instructions
1. Place a pilot pin in the cutter at the shank end. Insert the cutter into the special
arbor, aligning the flats to the set screws on the arbor. Secure the set screws to the
cutter with the supplied hex wrench.
2. Position the machine on a clean, dry, ferrous surface at least 1/2” thick. Switch on
the magnet.
3. Cutting fluid must be used at all times to enhance the quality of cut and prolong
the cutting tool life. Cutting fluid is applied through small holes located at the
top/shank end of the arbor and feeds via gravity.
4. Switch on the drill. Always proceed with caution at the start of drilling operations.
When using RotoBrute annular cutters apply pressure gradually at first until a depth
of 1/8” is reached. Normal cutting pressure can then be applied.
5. On completion of cut, withdraw the cutter from hole, switch off the drill, then the
magnet. Ensure the magnet base is clear of chips. Locate the next hole using the
above procedures.
Adjusting Dovetail lides
Slowly adjust the hex screws while moving the handle up and down. Adjust so there
is no free play or no binding anywhere through its range of travel. Periodically check,
lubricate, and adjust as necessary.
Repositioning of Handles
1. Elevate the slide upward to its full extent.
2. Remove the pinion cap screw and pinion cap from the shaft end
(opposite side to handles).
3. Slide the pinion with the handles on outward, approximately 1/3rd distance.
4. Disengage the rack by means of raising the slide up by another 3/4”.
5. Remove pinion, reposition through opposite side of body casting and reverse
procedure as above.
Assembly of Arbor for use with Annular Cutters
1. Align arbor support bracket with holes on dovetail slide.
2. Align support screws with holes and tighten clockwise.
3. IMPORTANT - do NOT tighten all the way until arbor is in place.
4. Place arbor through center hole of support bracket, making sure spindle bushing col-
lar is upright. Align with 1/2-20 threaded spindle and tighten clockwise.
5. When arbor is in place, tighten arbor support screws.
6. To remove arbor, use the 17mm wrench provided to hold the spindle nut in place.
Use the 7/16” wrench to hold the flats while turning counter-clockwise to loosen.
Assembly of Drill Chuck for use with traight hank Tools
An important feature of the RB32 is that it can quickly and easily be converted to oper-
ate standard twist drills and other straight shank cutting tools such as chassis ream-
ers. To remove the arbor assembly:
1. Use the included 5mm hex wrench to remove the two arbor support screws.
2. Loosen 3/4” arbor by unscrewing in counter-clockwise direction, using a wrench on
flats located at top of arbor.
3. Remove arbor support bracket.
4. Screw on 3-jaw chuck, supplied, and install safety screw to prevent drill chuck from
becoming frozen.
5. Insert twist drill or other straight shank cutting tool and tighten with chuck key. To
remove drill chuck, reverse procedure.
Assembly of Traverse Handles
1. To assemble traverse handle, place each of the three (3) handles into the threaded
holes on the pinion shaft., turning clockwise to tighten.
2. To remove handles, turn counter-clockwise.
Assembly of afety Guard
• Loosen screw from underneath the arbor support (front/center). Align the bracket slot
with the screw, and tighten screw until safety guard locks into place.
• To remove safety guard, loosen screw and remove safety guard.
