1. Install the unthreaded backing flange

(G) on spindle (D) with the raised section

 

(pilot) against the wheel. Be sure the

 

backing flange recess is seated onto the flats of the spindle by pushing and twisting the flange before placing wheel.

SURFACE GRINDING WITH GRINDING WHEELS

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3.Maintain a 20˚ to 30˚ angle between the

tool and work surface.

2.Place wheel against the backing flange, centering the wheel on the raised sec- tion (pilot) of the backing flange.

3.While depressing the spindle lock but- ton, thread the clamp nut (H) on spin- dle. If the wheel you are installing is more than 1/8" (3.31mm) thick, place the threaded clamp nut on the spindle so that the raised section (pilot) fits into the center of the wheel. If the wheel you are installing is 1/8" (3.31mm) thick or less, place the threaded clamp nut on the spindle so that the raised section (pilot) is not against the wheel.

4. Continuously move the tool in a forward

 

and back motion to avoid creating

20˚-30˚

gouges in the work surface.

 

5.Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

EDGE GRINDING WITH GRINDING WHEELS

CAUTION: Wheels used for cutting and edge grinding may break if they bend or twist while the tool is being used to do cut-off work or deep grinding. To reduce the risk of serious injury, limit the use of these wheels with a standard Type 27 guard

to shallow cutting and notching (less than 1/2" in depth). The open side of the guard must be positioned away from the operator.

4.While depressing the spindle lock button, tighten the clamp nut with a wrench.

5.To remove the wheel, depress the spin-

dle lock button and loosen the threaded clamp nut with a wrench.

NOTE: If the wheel spins after the clamp nut is tightened, check the orientation of the threaded clamp nut. If a thin wheel is installed with the pilot on the clamp nut against the wheel, it will spin because the height of the pilot prevents the clamp nut from holding the wheel.

For deeper cutting with a Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart on page 7 for more information. Type 1 guards are available at extra cost from your local dealer or authorized service center.

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.
