INSTALLING OR REMOVING DEPRESSED
CENTER GRINDING WHEELS:
WArninG:
Always be sure that the tool is switched off and unplugged before adjusting,
adding accessories, or checking a function on the tool.
1. Mount the inner flange with the machined side down onto the spindle. Slowly rotate the inner flange
until it engages the corresponding machined “flats” on the spindle shaft.
2. Slide the wheel, depressed side down, over the spindle shaft and over the raised shoulders on the
inner flange.
3. Screw the outer flange onto the spindle with the shouldered side down.
4. firmly depress the spindle lock so the spindle cannot revolve; then use the lock nut wrench, turning
it clockwise, to securely tighten the outer flange.
5. To remove the wheel, follow the installation procedure in reverse.
INSTALLING OR REMOVING AN ABRASIVE DISC:
WArninG:
Always be sure that the tool is switched off and unplugged before adjusting,
adding accessories, or checking a function on the tool.
1. Mount the optional rubber backing pad onto the spindle.
2. Place abrasive disc onto the spindle, then fit the disc onto rubber pad and begin to screw the outer
flange onto the spindle.
3. firmly depress the spindle lock so that the spindle cannot rotate, then use the lock nut wrench and
securely tighten clockwise.
4. To remove the disc, follow the installation procedure in reverse.
GRINDING AND SANDING OPERATION:
WArninG:
Never force the tool; the weight of the tool applies adequate pressure.
forcing and excessive pressure could cause dangerous wheel breakage.
ALWAyS replace the wheel if the tool is dropped while grinding.
NeVeR bang or hit the grinding wheel or disc onto the work.
Avoid bouncing and snagging the wheel, especially when working on corners, sharp edges, etc. This
can case loss of control and kickback.
NeVeR use the tool with wood carving blades or other saw blades. It is only designed for grinding,
sanding, or wire brushing.
CAUTiOn:
After operation, always switch off the tool and wait until the wheel comes to a
complete stop before putting the tool down.
ALWAyS select and use grinding wheels that are recommended for the material to be ground. ensure
that the minimum operating speed of any accessory is compatible with the RPMs of the tool.
ALWAyS hold the tool firmly with one hand on the motor housing and the other on the side handle. Turn
the tool on and then apply the wheel or disc to the workpiece. The key to efficient operation begins by
controlling the pressure and surface contact between grinding wheel and the workpiece. flat surfaces
are usually best ground by keeping the edge of the wheel at an angle of 5 to 15 degrees.
Maintaining the proper angle of 5 to 15 degrees by tilting the grinder and continuously moving the
grinder back and forth or up and down over the work area. Keep the grinder moving to avoid removing
a excessive amount of material from one area.
use just enough pressure to keep the tool from chattering or bouncing; normally the weight of the tool
alone is adequate for most grinding jobs. Where there is a chance that the grinding wheel may get
snagged by the workpiece, such as loose bolts or jagged edges, causing loss of tool control, use
lighter pressure.
