WARNING Always remove battery pack before changing or removing accessories. Only use accessories specifi- cally recommended for this tool. Others may
be hazardous.
WARNING To reduce the risk of injury, wear safety goggles or glasses with
side shields.
WARNING Only use accessories with Maximum Safe Operating Speed rated at least equal to the maximum speed marked
on the power tool. This speed is based on the strength of the wheel, allowing for a reasonable measure of safety. It is not meant to imply a best or most efficient operating speed. Do not exceed the Maximum Safe Operating Speed.
Grinding Wheel / Sanding Disc Selection Use sanding discs and grinding wheels that are:
•correct size as written on tool's nameplate.
•correct wheel type and grit for the job.
•rated at or above the RPM listed in the "WARN- ING" section on the tool's nameplate.
Use backing pads, adapters, and other acces- sories that are:
•correct size for tool and for sanding disc or grind- ing wheel.
•rated at or above the RPM listed in the "WARN- ING" section on the tool's nameplate.
•the proper accessory for the job.
Selecting Wheels
Grinding is the cutting action of thousands of abra- sive grains on the face of a grinding wheel. When grinding metals such as steel and iron, choose an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel for stone and concrete. Use cotton reinforced wheels for non-ferrous metals.
Type 27 Reinforced 1/8" thick or less Cut-Off Wheels are suited for small cut-off and shallow notching operations only.
Grinding and Cut-off Wheels
Always handle wheels carefully to avoid damage. Before installing any wheel, always inspect it for cracks. If wheel is cracked, discard it to prevent others from using it.
WARNING To reduce the risk of injury, the operator should be instructed in the use, care and protection of grinding wheels.
Care of Grinding & Cut-Off Wheels
Grinding and cut-off wheels should be protected from:
•wetness and extreme humidity
•any type of solvent
•extreme changes in temperature
•dropping and bumping
Grinding and cut-off wheels should be stored:
• in an organized way so wheels can be removed without disturbing or damaging other wheels
• with their safety information
6
Grinding and cut-off wheels should NOT be:
•dropped
•rolled
•bumped
If any wheel is dropped, rolled, bumped, subjected to extreme changes in temperature, or has come into contact with solvents or wetness, discard wheel immediately.

3.Place the flange on spindle.
4.Place the selected wheel on the spindle and align it with the flange.
5.Position the flange nut over the spindle according to wheel thickness (Fig. 3).

6.Press in the spindle lock button while turning the flange nut clockwise. Tighten securely using a spanner wrench.
7.To remove wheel, remove the battery pack and reverse the procedure.
just beginning a period of work, test wheel by |
letting it spin for one minute before applying it to |
the workpiece. |
NOTE: Out-of-balance wheels can mar work- |
piece, damage the tool, and cause stress to |
wheel that may cause wheel failure. |
2.Use a clamp, vise or other practical means to |
hold your work, freeing both hands to control |
your tool. |
3. When grinding, hold sander/grinder at a 5o to |
15o angle, using constant pressure for a uniform |
finish. Too great an angle causes concentrated |
pressure on small areas which may gouge or |
burn work surface. |

Hold at a 5° to 15° angle
For best result use only this portion of disc
4.To start the tool, grasp the handle and side handle firmly and slide the switch to ON.
5.Allow grinding wheel to come to full speed before beginning work.
6.Control pressure and surface contact between wheel and workpiece. Too much pressure slows grinding speed.
7.To stop the tool, release the switch. Make sure the tool comes to a complete stop before laying the tool down.
8.To lock-onthe switch, slide the switch to ON and then press down on the front of the switch. To stop the tool, press and release the switch. Make sure the tool comes to a complete stop before laying the tool down.
Using Cut-Off Wheels
WARNING A Type “1” guard must be installed when using a cut-off wheel to provide maximum protection for the opera-
tor if the wheel should break.
Type “1” Cut-Off Wheels are suited for small cut-off and shallow notching operations only.
1.Firmly grasp body of tool and side handle before starting and while using tool.Allow wheel to come to full speed before starting.
2.When using a cut-off wheel, hold Sander/Grind-
er as shown, using only the edge of the wheel.
3.Control pressure and surface contact between disc and workpiece. Too much pressure slows cutting speed.
Wheel (as in grinding) will cause the Wheel to crack and break, resulting in serious personal injury.
Installing Wire Cup Brushes
WARNING Everyone in the area must wear protective clothing and safety goggles or face shields. Fatigued wires and residue will fly off the brush with considerable
force, causing potential for serious injury.
1.Unplug tool and place it upside down on a level surface as shown. Remove any accessories from spindle.
2.To install, thread wire cup Wire Cup brush onto spindle. Press Brush the spindle lock button
while tightening brush with a 7/8" open end wrench (not provided with tool).
3.To remove wire cup brush, unplug tool and reverse procedure.
Using Wire Wheel Brushes
WARNING Because the wires on wire wheel brushes are directed towards the operator, a guard must be used to protect
the operator when fatigued wires break.
Wire wheel brushes are useful for removing rust, scale, burrs, weld slag, etc. Guard Awide variety of wire brush-
es are available for many applications.
Test wire wheel brush for balance and loose or dam- aged wires by running tool
at no load speed for at least one minute before applying it to your work. During this time, no one should stand in front of or in line with it. When ap- plying brush to work, avoid using too much pressure. This causes over-bending of wires and heat build-up resulting in premature wire breakage, rapid dulling and reduced brush life. Instead of using more pres- sure, try a wire wheel brush with more aggressive cutting action (increased wire size, decreased wire length or different brush type, i.e. knot type instead of crimped wire type).
WARNING Never exceed Maximum Safe Operating Speed of brush. Do not use a damaged brush or one which is functioning improperly (throwing wires, out-of balance, etc.). these conditions increase the possibility of further brush failure and possible injury. Discard and replace damaged brushes im- mediately.
