Cord-connected Grinders -- The Grinder is equipped with an approved 3-conductor cord and a 3-prong grounding type plug to fit the proper grounding type receptacle. The green conductor in the cord Is the grounding wire. Never connect the green wire to a live terminal. If your Grinder is for use on less than 150 volts, it has a plug and outlet as Illustrated in Figure A. There is no adaptor for Figure B plugs and outlets {230 volts). hand edge, in from the front edge so it is s till com fortable to reach brake shoes in the Clamp. Assemble the complete Dust Collection System and attach it to the Brake Shoe Grinder exhaust port temporarily, supporting it as necessary. Turn the Shoe Grinder ON to inflate the Dust Bag and position both units so there is no air restriction or unnecessary strain on the Dust Bag. Center punch and drill the four mounting holes in the Guard Assembly and fasten the Dust Collector to the bench end. On an AMMCO Model 9890 Bench: Use the template and Instructions supplied with the Dust Collection System. Use only 3-wire extension cords which have 3-prong grounding type plugs and 3-pole recep tacles which accept the Grinder's plug. Replace or repair damaged or worn cords immediately. Permanently connected Grinders -- The Grinder may be connected to a grounded, metal-enclosed wiring system such as that installed by a licensed electrician. A separate grounding conductor (wire) should be connected to the equipment grounding lermlnal on the Grinder Motor. See manufacturer's recommendations for electrical hook-up wire size, running overload protection, lubrication, repair parts, and Installation onpagelB. GRINDER & DUST COLLECTOR SET-UP The Grinder and Dust Collection System are mounted on the right hand end of a bench and, since the Dust Collector is attached to the bench end panel, the Shoe Grinder should not be bolted down until both units are properly positioned. On an existing bench (other than an AMMCO Model 9890 Mobile Bench): Set the Grinder on the bench top close to the right ASSEMBLE THE DUST COLLECTOR Refer to .the illustrated parts list for proper parts positioning. 1. Slip the Ring and Seal onto the C ollector Elbow and join the Dust Collector to the Grinder exhaust port. 2. The Clip, part number 11197, straddles the Elbow behind the two protruding lugs. The "fee t" of the Clip hook under the Grinder Base to provide the necessary grip to seal the two units together when the Clip is snapped over the Stud. 3. The Dust Bag and rubber Seal are pushed down through the Guard to hang above the Pail. 4. Press a plastic Disposal Bag into the bottom of the Pail and fold the excess over the top edge. Lift the Pall up under the Guard Assembly and press it against the rubber Seal to seat it in the Ring. Clamp the Pail on. ABRASIVE BELTS. To replace an Abrasive Belt, remove the two thumb screws and lift off the Abrasive Belt Guard. Remove the two alien screws from the Retaining Clip, along with the Hold Down Clip. Pull the Retaining Clip up and away from the Belt, or slip the Belt and Clip off the Arbor together. Remove the Clip from the Belt.

Place the lined shoe in the shoe Clamp: No. 8050 and No. 8150 Clamps -- visually center the lining in the Clamp -- NOT the entire shoe. No. 8250 Clamp -- the shoe anchor eye is set against the proper Anchor Sleeve. See page 9. B. When the shoe is fully seated, tighten the Clamp. Refer to picture callouts for identification of operating parts. 2. Release the Slide Lock, the lever located beneath the Swivel Base and on top of the Slide Table on the right hand side. 3. Adjust the Micrometer Dial to zero. 4. Pull the Slide Index Pin outward and slide the Table to the proper drum diameter indicated on the Drum Diameter Scale: 6" to 16". n MICROMETER SET AT ZERO r\ MICROMETER SET AT .MO' GRINDING THE SHOE: BEFORE STARTING THE MOTOR, be sure the Dust Collection System and Abrasive Belt are correctly installed and in proper working order. The Dust Collector works auto matically each time the Shoe Grinder is turned on. Lift the Operating Handle out of the half-nut and push the entire Clamp with the shoe toward the Abrasive Belt. Stop when the shoe is just barely clear of the Belt and lower the Operating Handle back into the half-nut. Swing the Handle away from you (toward the Dust Bag) and start the motor. Twisting the Operating Handle clockwise ad vances the shoe into the Abrasive Belt. The Grin ding Scale at the forward end of the Operating Handle is graduated in THOUSANDTHS and is read by the operator to set the amount of grind for each swing of the Handle. It is also read to keep the lining thickness of each set of brake shoes the same. 5. Set the Micrometer Dial to the exact drum diameter measurement needed: .000" to 1.000*. The Dial has a range of 1' and thus can be set for any intermediate dimension. Each full revolution of the Dial changes the diameter .200' . NOTE The Grinders are factory calibrated to grind .060' SMALLER than the actual drum diameter. This is done automatically--you set the Micrometer Dial to the EXACT drum diameter needed. 6. Tighten the Slide Lock before grinding by pulling the lever toward you. CLAMPING THE SHOE: Reter to the illustration that shows the type of Clamp used in your Grinder. In general, the No. 8050 Universal Brake Shoe Clamp grips the shoe on the edges of the shoe backing plate while the No. 8150 and No. 8250 Clamps grip the shoe on its w e b . Advance the shoe no more than .005' at a time and do it only when the Operating Handle is on the Dust Bag side of the Grinder. This w ill provide a smooth cut. Move the Handle at an even rate across the entire shoe and try not to grind too fast. Continue grinding until the shoe lining cleans up across its full arc -- then stop. Additional grinding w ill only waste lining. Read the total amount of lining removed from the shoe by checking the Grinding Scale. Use this as a reference when grinding the rest of the set of shoes. The brake shoe has now been "cam ground" and its radius is .060" smaller than the inside radius of the finished drum. This grind provides a slight toe and heel clearance at the very ends of the shoe lining segment of about .005' to .008'.
