• DO NOT attempt to operate without guards, shields and guides in place! Serious injury could result!
• DO NOT attempt to operate without base being securely and firmly attached to a solid work surface. Serious injury could result.
• IMPORTANT NOTE: Grinding creates hot sparks and metal fragments which are ejected from the wheel at a considerable distance.
°Keep flammable materials and liquids away from the grinding area.
°Use appropriate ANSI or CSA approved eye and face protection.
°Keep people and pets away from the grinding area.
°Keep long sleeves, other loose clothing and long hair away from rotating wheels. Serious injury could result.
• Buffing can emit hazardous dust and fibers. Use appropriate NIOSH approved breathing protection.
• Keep fingers and hands away from rotating wheels. Use locking pliers or other suitable device to firmly hold smaller items while grinding or buffing.
• Should grinding wheel become cracked or an unbalanced condition or vibration develops, TURN OFF SWITCH and STOP USE IMMEDIATELY!

GRINDER OPERATION
• The grinder MUST be securely bolted or clamped to a solid work surface at a comfortable working height.
• Make sure the switch is in the OFF position before plugging in.
• Stand to one side and turn switch on then allow motor to reach operating speed. Check for vibration and shut-off immediately if any vibration is detected.
• VERY IMPORTANT! The wheel rotates in a Clockwise direction when viewed from the left side. When viewed from the front, the top segment of the wheel exposed by the
shield is rotating toward the operator. ALWAYS grind objects pointing slightly downward and NEVER upward as they can be violently hurled toward you causing severe
injury or death!
• Only apply a very light pressure against the wheel when grinding. NEVER push an object hard against a grinding wheel.
• Always use the tool rest for support and stabilization.
• Only allow the object being ground to contact the wheel for several seconds at a time. Heat will quickly build in the wheel and ground object which can cause damage and
burns. Dip the object into the coolant in the tray as required.
• NEVER grind against the side of the wheel as an imbalance condition or even cracking can occur.
BUFFER OPERATION
• Stand to one side and turn switch on then allow motor to reach operating speed. Check for vibration and shut-off
immediately if any vibration is detected.
• VERY IMPORTANT! The Buff Wheel rotates in a Counter-Clockwise direction when viewed from the right side. When viewed from the
front, the top is rotating toward the operator. ALWAYS work on the segment of the buff wheel BELOW the centerline of the shaft so
that it is rotating down and away from you. If applied ABOVE the centerline, objects can be violently hurled toward you causing severe
injury or death (Fig E).
• ALWAYS buff objects pointing slightly downward and NEVER upward as they can be violently hurled toward you causing severe injury
or death!
• Apply buff compound sparingly to the buff wheel, too much will clog the fibers and create a build-up on objects being buffed, prevent-
ing effective buffing.
• NOTE: The spiral-sewn, cotton buff wheel is a general use buff wheel which can be used with a variety of compound grades. Do not attempt to use different compounds
on a single buff wheel. It is best to use a different buff wheel for each compound grade. There is an excellent selection of buffing compounds and buff wheels available in
various forms of aggressiveness available at Eastwood. Please consult www.eastwood.com or request a catalog to view the selections available.
GENERAL TROUBLESHOOTING

°Check 120 VAC input plug connection. °Check for binding of shielding, tool rests or guards against wheel.
• Motor slows down while operating:
°Too much pressure being applied to the wheel. Reduce pressure. °Check for binding of shielding, tool rests or guards against wheel.

TROUBLESHOOTING – GRINDER SPECIFIC
• Burned appearance on ground object:
°Too much pressure being applied to the wheel. Reduce pressure.
°Ground object being held too long against wheel. Grind several seconds on, wait several seconds, re-grind.
°Dip ground object into coolant.
• Wheel wearing rapidly:
°Too much pressure being applied to the wheel. Reduce pressure.
°Wheel too soft for material being ground, use harder wheel.
°Ground object being held too long against wheel. Grind several seconds on, wait several seconds, re-grind.
• Wheel loading up with metal:
°Too much pressure being applied to the wheel. Reduce pressure.
°Wheel too hard for material being ground, use softer wheel.
°Ground object being held too long against wheel. Grind several seconds on, wait several seconds, re-grind.
°Too much heat in ground object. Dip into coolant.
TROUBLESHOOTING – BUFFER SPECIFIC
• Buff Wheel spreading or fraying:
°Too much pressure being applied to the wheel. Reduce pressure.
°Buffed object too course for wheel grade. Choose a courser buff wheel.
• Buff Wheel loading up or glazing:
°Too much buff compound being applied to the wheel. Clean wheel by GENTLY applying a large screwdriver blade pointing DOWNWARD against rotating
wheel to clean. Apply less compound to wheel.
• Buildup or caking of compound on object being buffed:
°Too much buff compound being applied to the wheel. Clean wheel by GENTLY applying a large screwdriver blade pointing DOWNWARD against rotating
wheel to clean. Apply less compound to wheel.
