EXTENSION CORD USAGE Extension cords are not recommended for use with this bench grinder . Extension cords, if used, must be properly grounded with a 3-prong plug on one and a 3-hole receptacle on the other . DO NOT use grounding adapters with an extension cord. Extension cords must be UL listed and use a minimum of 18 A.W .G. wiring. Extension cords should never exceed 25 feet in length. Extension cords, that are too long, cause a voltage drop over the extra distance causing the grinder motor to run slower with the possibility of causing damage to the motor . Using extension cords with smaller than the recommended wire gauge run the risk of getting too hot, melt- ing, and/or causing fires. See table, “Extension Cord Specifications”, on page 18. IMPOR TANT SAFETY RULES FOR BENCH GRINDERS ALWAYS wear protective eyewear and/or appropriate dust filters and respirator when using this tool. DO NOT OPERA TE THIS BENCH GRINDER until it is completely assembled according to the instructions in this manual. Failure to adhere to these instruc- tions could result in serious and/or permanent injur y. OBT AIN ADVICE FROM A QUALIFIED INDIVIDUAL if you are not completely sure how to use the bench grinder . USE RECOMMENDED ACCESSORIES. Consult the owners manual for recom- mended accessories. The use of improper accessories may cause cause risk of injur y. NEVER ST AND ON TOOL. Serious injur y could occur if the tool is tipped or if the cutting tool is unintentionally contacted. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and per form its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other con- ditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. DIRECTION OF FEED. Only feed work into a blade or cutter against the direc- tion of rotation of the blade or cutter . GROUNDING INSTRUCTIONS The electrical power sour ce for this bench grinder MUST be grounded in order pre- vent possible electric shock or even death should the tool malfunction or break- down. Grounding provides a path of least resistance for electric current thus reduc- ing the risk of electrical shock. The power sour ce must also use a minimum 20A ser vice and not used if other power tools on the same circuit are in use. This bench grinder is equipped with a grounded 3-wire power cord with a 3-prong plug. If the power cord will not fit into the wall plug, an approved adapter can be used as long as it is connected to the center screw in the wall plate. Never modify the electrical plug by cutting off the grounding prong so it will fit into unapproved, un-grounded electrical receptacles. See Figure 1. If you have questions about hooking up the bench grinder , contact a certified elec- trical contractor to install the proper circuitr y acceptable for this and other power tools you use.

DO NOT ST AND DIRECTL Y IN FRONT OF THE GRINDER when it is first turned on. Loose fragments could fly off at high speeds possibly causing injur y. NEVER ENGAGE A WORK PIECE TO A COLD GRINDING STONE. A cold grind- ing stone has a tendency to chip. Allow the grinder to run for an entire minute before applying the work piece to the grinding stone. NEVER ST AR T THE BENCH GRINDER WITH THE WORK PIECE AGAINST THE GRINDING WHEEL. The work piece can be drawn into the grinding wheel causing it to fragment resulting in damage to the grinder and/or serious injur y to the operator . THOROUGHL Y CLEAN THE GRINDER BEFORE CHANGING TYPES OF WORK PIECES. Combining wood and metal dust can result in an explosion or fire. DO NOT GRIND OR POLISH WORK PIECES MADE OF MAGNESIUM. The magne- sium could ignite resulting in a ver y intense fire that could cause severe burns to the operator and/or seriously damage the bench grinder . NEVER PERFORM GRINDING OPERA TIONS NEAR FLAMMABLE GAS OR LIQUIDS. The resulting fire and/or explosion could cause permanent serious injuries to the operator and damage to the grinder and surrounding work area. AVOID AWKW ARD POSITIONS for both hands and work pieces. A sudden slip could draw fingers into the grinding wheel causing injur y. ALWAYS KEEP ARMS, HANDS, AND FINGERS away from the grind wheel sur face. Severe injur y could result. HOLD THE WORK PIECE FIRML Y AGAINST THE GRINDING WHEEL. A loose grip can cause loss of control of the work piece resulting in severe injuries or damage to the bench grinder . ALWAYS MAKE CONT ACT WITH THE FACE OF THE GRINDING STONES. Grinding objects on the side of the grinding stones can cause the stones to frag- ment resulting in fragments being thrown from the wheel at high speeds. Serious injur y could result. NEVER APPL Y A COOLANT DIRECTL Y TO THE WORK PIECE WHILE IT IS IN CONT ACT WITH THE GRINDING STONE. Coolant can weaken the makeup of the grinding stones causing them to fail. Dip the work piece in water to cool it. DO NOT TOUCH THE GROUND POR TION OF THE WORKPIECE until it has prop- erly cooled. Touching HOT sur faces can cause injur y. NEVER PERFORM LA YOUT OR ASSEMBL Y to work pieces in front of the grinder while it is still running. A sudden slip could bring hands in contact with the moving parts of the bench grinder resulting in injur y to the operator . 7 8 FOLLOW ALL WIRING CODES. Use only properly grounded three-hole ground- ed receptacles. DO NOT cut the third prong off the power cord. When using an extension cord, use only UL Listed extension cords with minimum 16 AWG wiring and a maximum length of 25 feet. See ELECTRICAL SAFETY section in this manual. KEEP BYST ANDERS, CHILDREN, AND VISITORS at a safe distance from the bench grinder while it is in operation. Distractions can cause inadvertent misuse resulting in possible injur y to the bystanders or to the operator . ALWAYS USE THE PROVIDED WHEEL FLANGESto mount grinding wheels on the grinder shaft to prevent wheel damage or separation. Separation can result in frag- ments flying off the wheel at high speeds possibly causing severe injuries. USE ONL Y GRINDING WHEELS AND MET AL BRUSHES that are designed for the speed of this grinder . Unsuitable grinding wheels can separate throwing frag- ments outward at high speeds possibly causing severe injuries. NEVER ATTEMPT TO USE A GRINDING WHEEL OR MET AL BRUSH with an arbor hole different from the motor shaft on the grinder . DO NOT OVER TIGHTEN THE ARBOR NUT .Excessive tightening can cause the wheel to fracture and possibly break apart during use and throw pieces outward at high speeds. DO NOT USE A GRINDING WHEEL THAT VIBRATES.Visually inspect the grinding wheels and dress them as necessary or replace them immediately. If the vibration still exists, check the bearings on the motor shaft and repair or replace them as soon as possible. EXCESSIVE VIBRATION can cause wheel separation. REPLACE A CRACKED WHEEL IMMEDIA TEL Y. ADJUST THE EYE SHIELDS SO THEY ARE CLOSE TO THE WHEELS.Re-adjust the shields as the wheel wears down. Flying sparks are dangerous and cause fires and/or explosions if they come in contact with flammable materials or liquids. MAKE SURE THE EYE SHIELDS ARE IN PLACE and properly adjusted and secured at all times the grinder is in use. ADJUST THE TOOL RESTS BEFORE EACH USE. The tool rests should be close to the grinding wheels (about 1/8 separation or less). The tool rests should always be tightened to prevent shifting in positions. They should be re-adjust- ed, as needed, as the grinding wheel wears down. If not properly adjusted, the work piece can be inadvertently drawn into the grinding wheel causing damage to it or possible severe injur y to the operator .

INST ALLA TION INSTRUCTIONS Do not begin assembly of bench grinder if the AC power cord is plugged into an AC power receptacle. Do not begin assembly of bench grinder if power switch on the front of the base is switched to the “ON” position. INSPECTION: Carefully inspect each individual part of the bench grinder to ensure there are no cracked, broken, or bent components needed for a safe installation. 1. Carefully choose a location for the bench grinder . If mounted on a workbench, ensure there is adequate room all around the grinder for safe operation. The area must be level and clear of other power tools and/or power tool cords that could inter fere with operation of the bench grinder . 2. If the bench grinder is installed on a universal tool stand (available at larger hardware stores), ensure there is plenty of unobstructed space around the grinder as not to inter fere with safe operation on the tool. 3. The bench grinder should be installed in a place that is away from outside ele- ments and close to an approved power receptacle so that an extension cord will not be needed. Should an extension cord be needed, refer to Page 18 in this manual for choosing the proper length and wire gauge needed for safe opera- tion of the bench grinder . 4. Do not assemble and/or use the grinder in an area that may be contaminated with oily rags. Keep flammable materials such as gasoline, paint thinner or sol- vents. Sparks from normal grinding operations can ignite these compounds resulting in moderate to severe burns to the operator . 5. Carefully inspect the grinding wheels to ensure they were not damaged during shipment. Fractured grinding wheels can shatter during grinding operations and throw off pieces at high speeds. Failure to adhere to these cautions can cause severe injur y including blindness or even death to the operator . INST ALLING THE TOOL RESTS When installing the Tool Rests on the bench grinder , NOTE there is a Left Tool Rest and a Right Tool Rest. The tool rest shelf ALWAYS points away from the motor and the two different tool rests cannot be installed on the wrong side. See Figure 2. 1. Remove the two mounting bolts (1) and washers (2) from the inside of the Grinding Stone Guard (4). 2. Insert the mounting bolts and washers through the slotted hole at the bottom of the Tool Rest (3) and reattach them to the Grinding Stone Guard. 3. Position the Tool Rest no more than 1/8 away from the Grinding Stone (5). 4. Tighten the two mounting bolts securely , using the appropriate size metric combination wrench, to prevent the Tool Rest from moving during usage of the bench grinder . 5. As the grinding stones wear down, loosen the two mounting bolts and adjust the tool rest inward maintaining the 1/8 gap. 6. Re-tighten the two mounting bolts securely , using the appropriate size metric combination wrench, to prevent the Tool Rest from moving during usage of the bench grinder . Ensure the Tool Rest is securely tightened before turning the bench grinder power switch to “ON!” Always replace a Tool Rest should it become broken.

OPERA TING THE ON/OFF SWITCH The bench grinder “ON/OFF” switch is located on the front of the grinder base. To turn the grinder “ON,” move the rocker -style switch to the right to the “ON” position. To turn the grinder “OFF ,” move the rocker -style switch to the left to the “OFF” position. GRINDER OPERA TIONS •Before starting any grinding operation, check the grinding wheels are properly dressed and have no rounded edges, gouges, or grooves. Refer to the section, “Maintenance and Cleaning” (page 15-18) for procedures on dressing the grinding wheels. •Ensure the tool rests are securely tightened and the eye shields are in place and properly tightened. •Allow the grinder to run for at least one minute to warm up the grinding wheels. NEVER place a work piece against a “COLD” grinding wheel. •The bench grinder is equipped with two aluminum oxide grinding wheels - one 36 grit (coarse) and one 60 grit (medium). •Place the work piece on the tool rest and apply even pressure as contact is made with the abrasive stones. •If the grinder is being used to sharpen heavy tools such as axes or lawnmower blades, start by using the coarse grinding wheel. This wheel removes a greater amount of sur face. Then repeat the procedure using the medium wheel to give the tools a finished sharpening. NOTE: The finished edges on heavy tools such as axes or lawnmower blades need not be ground to a fine edge like that of a pocket knife or scissor . The edge needs to be free of nicks and uneven edges for maximum performance. A fine edge will only become damaged easier requiring more frequent sharpening. • When sharpening tools, start on one end of the tool and slide its sur face across the grinding stone in a firm even speed and pressure. Reverse the direction for the other side. When sharpening tools on a grinder , avoid letting the tool stay in one place until it becomes “RED HOT .” You will notice area will change color , possibly to a bluish tint, when the tool cools. This change in color and the exposure to high heat can alter the tempering of the metal making it more brittle and subject to frequent sur face damage. 14 13 INST ALLING THE EYE SHIELDS The Eye Shields prevent hot sparks and other debris from flying off the spinning grind wheels and possibly causing injur y to the eyes of the operator . The eye shields can be mounted in different positions depending on the operator . See Figure 3. 1. Attach the clear plastic Eye Shield (1) to the Eye Shield Mounting Bracket (3) using the two mounting screws (2) as shown in Figure 2. 2. Attach the Eye Shield and Mounting Bracket to one of the three mounting holes in the Grinding Stone Guard (5) using the Adjustment Knob, Split-lock Washer and Flat Washer (4). 3. Adjust the Eye Shield by loosening Adjustment Knob and positioning in a desired position. Re-tighten the Adjustment Knob securing the Eye Shield to the grinder . Ensure the Eye Shield is in the preferred location and securely tightened before turning the bench grinder power switch to “ON!” Always replace an Eye Shield should it become cracked, broken or scratched to that the view through it is impaired. Contact Alltrade Customer Ser vice at 1- 800-590-3723 (toll free) for authorized replacement parts. OPERA TING THE BENCH GRINDER Ensure the “ON/OFF” switch is in the “OFF” position before plugging the power cord into the AC power source. Ensure there are no tools or work pieces in contact with the grinding wheels when the grinder is turned “ON.” Failure to obser ve these procedures could result in damage to the bench grinder , tools, work pieces, or serious personal injur y to the operator or bystanders. FIGURE 3. INSTALLING THE EYE SHIELD 4 3 2 51
4. Remove the rear bolt attaching the Tool Rest to the Grinding Wheel Guard. 5. Loosen the front bolt on the Tool Rest. Move the Tool Rest for ward as far from the Grinding Shield Guard as possible and re-tighten. 6. Wedge a small piece of wood between the Grinding Wheel Guard and the Grinding Stone to prevent it from turning. 7. Using a wrench, loosen and remove the Arbor Nut (4) from the Motor Spindle (8). The Motor Spindle has left-hand threads on the left side and right-hand threads on the right side. Left-hand threads LOOSEN by turn- ing them clockwise where as right hand threads loosen by turning them counter -clockwise. This prevents the spindle nuts from becoming loose dur- ing grinder operations. DO NOT attempt to “grind” work pieces made of WOOD or MAGNESIUM. Using wood with a bench grinder could easily start a fire or cause severe irreversible damage to the work piece. Grinding work pieces made of magnesium or magnesium alloys can ignite causing sudden ver y intense fires. Magnesium fires cannot be easily extinguished. ABSOLUTEL Y DO NOT THROW WATER ON A MAGNESIUM FIRE. USE ONL Y A FIRE EXTIN- GUISHER RA TED FOR SUCH FIRES OR CALL FOR ASSIST ANCE (9-1-1). When water is introduced to a magnesium fire, the sudden temperature change could cause the metal to explode sending ver y hot pieces throughout the work area possibly igniting other fires. •Use optional accessories such as wire wheels and buffing wheels to create finishing touches to your work piece. •WIRE WHEELS should never be used on work pieces that are polished or have a textured sur face. The wheel will deface these sur faces. Like grinding stones, work pieces can be held too long against the wire wheels resulting in high temperatures and possible damage to the work piece. Consult with Alltrade Customer Ser vice at 1-800-590-3723 (toll free) for assistance in choosing the proper grinding wheels and accessories for your grinder . MAINTENANCE AND CLEANING During normal use, the abrasive grinding wheels may become cracked, grooved, develop rounded corners on the edges, chipped, loaded with foreign material or worn from the original shape and will need to be replaced. Grinding wheels that are chipped or cracked should be replaced IMMEDIA TEL Y. REPLACING GRINDING WHEELS When replacing grinding wheels, make sure the replacement wheel has a speed rat- ing at or above the speed of the grinder . The speed rating is listed on the nameplate of the grinder . Replacement grinding wheels should have a 1/2 arbor hole and a maximum width of 3/4. See Figure 4. 1. Ensure the POWER SWITCH (1) is set to the “OFF” position and the electrical power cord is removed from the power sour ce before changing grinding wheels.2. Loosen the Adjustment Knob and lift the Eye Shields to the UP position. The Eye Shield and Adjustment Knob are shown in Detail A, above. 3. Remove the three screws (2) and remove the outer cover of the Grinding Stone Guard (9). 15 16 FIGURE 4.

18 17 8. Remove the Outer Arbor Flange (5) and the old grinding wheel. 9. Slide the NEW Grinding Stone onto the Motor Spindle and ensure it seats with the Inner Arbor Flange (7). Install the Outer Arbor Flange (5) and the Arbor Nut (4). 10. Wedge a small piece of wood between the Tool Rest and the Grinding Stone to prevent it from turning. The Tool Rest is pictured in Detail A on page14. 11. Using a wrench, tighten the Arbor Nut (4). 12. Place the outer cover of the Grinding Stone Guard and secure it with the three screws (2) that were removed in Step 3, above. DRESSING THE GRINDING WHEELS After using the grinding for a period of time, the wheel sur face could become grooved and the edges rounded. Re-sur facing the grinding wheel is called “dress- ing the wheel.” Use a suitable silicone carbide, stick-type dresser or the wheel dresser provided with the grinder . An uneven grinding wheel can cause poor results upon grinding items that use the entire sur face of the wheel. Follow the steps below to dress the grinding wheel. 1.Turn on the grinder . 2.Set the dresser on the tool rest and move it for ward against the moving wheel until it touches the high point. 3. Dress the grinding wheel by moving the dresser back and forth. 4. Repeat this operation until the sur face of the grinding wheel is clean and free of grooves or gouges and the wheel edges are square to the wheel sur face. 5. Repeat this operation on both grinding stones. CLEANING THE BENCH GRINDER •The bench grinder should only be cleaned after the power cord is removed from the power sour ce and the Power Switch is turned to “OFF .” Clean any dust buildup from around moving parts or near electrical connections. This dust can possibly contain metallic shavings that could cause electricity to be conducted from the grinder parts to a grounded object. Use a clean rag, brush, or com- pressed air sour ce to remove excessive dust buildup. •NEVER use flammable materials to clean the grinder . •NO LUBRICA TION is required. The grinder motor uses sealed lubrication bearings installed at the factor y. FLEXIBLE WORK LIGHT The Work Light features two flexible arms with a light attached to each arm. •Turn the Power Switch to the “OFF” position and unplug the power cord from the electrical power sour ce. •To replace the Work Light bulbs, wait until they have cooled enough to safely handle, and unscrew the used bulb by turning it counter clockwise. •Install a new bulb in the W ork Light, insert it into the socket, and turn it clockwise. To prevent the possibility of fire, do not use light bulbs brighter than 15 watt and rated for 120V AC, 60Hz. ACCESSORIES Optional accessories for the bench grinder can include wire-brush wheels that can be used for cleaning and layered cloth wheels that can be used for polishing and buffing. Contact ALL TRADE Customer Ser vice at 1-800-590-3723 (toll free) to find out what accessories are available for the bench grinder . Only use accessories that are designed to fit your partic- ular grinder . These accessories should be specifically labeled to match the speed and arbor size of the grinder . Failure to use the proper accessories could result in property damage, damage to the grinder , and serious person- al injur y to the operator . Always attach grounded (3-prong) extension cords to grounded (3-hole) outlets. If the grinder must be used outside, use an extension cord labeled “W -A” or “W .” These extension cords are rated for outdoor use and reduce the chances of electrical shock. If you must use an extension cord, be sure that the gauge is large enough to carr y the amount of current necessar y for your power tool. If not, your tool may experi- ence a loss of power , excessive voltage drop or overheating. The smaller the gauge number , the heavier the cord (see table below).
