DeWalt DWE4517, DWE4519 Mounting Non-Hubbed Wheels Fig, Surface Grinding With Grinding Wheels Fig

i_WARNING: Failure to properly seat the wheel against the soft mount before turning the tool on may result in damage to the tool or the wheel

MOUNTING NON-HUBBED WHEELS (FIG. 8)

Depressed center, Type 27 grinding wheels FIG. 8 must be used with available accessory flanges. K See the chart on pages 11-13 of this manual for

more information.

1.Install the metal backing flange (K) on spindle (F)against the soft mount.

2.Place wheel against the backing flange, centering the wheel on the backing flange pilot.

3.While depressing the spindle lock button, thread the clamp nut (L) on spindle, piloting the raised hub on clamp nut in the center of grinding wheel.

4.Tighten the clamp nut with a wrench.

5.Reverse the above procedure to remove the wheel.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 9)

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

2.Apply minimum pressure to work surface, FIG.9 to allow the tool to operate at high speed.

3.Maintain a 20 °to 30 °angle between the tool and work surface.

4.Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface.

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

EDGE GRINDING WITH GRINDING WHEELS

WARNING: Wheels used for cutting and edge grinding may break or kick back if they bend or twist while the tool is being used to do cut-off work or deep grinding. Toreduce 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" (13 mm) in depth]. The open side of the guard must be positioned away from the operator. For deeper cutting with a Type 1 wheel, use a closed, Type 1 guard. 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 work surface, to allow the tool to operate at high speed.

3.Protect yourself during edge finishing by directing the open side of the guard away from you.

4.Move the tool continuously in a forward and back motion to avoid creating gouges in the work surface.

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

_, WARNING: Do not use edge grinding wheels for surface grinding applications because edge grinding wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result.

SURFACE FINISHING WITH SANDING FLAP DISCS (FIG. 10}

3. Allow the tool to reach full speed before touching tool to work

surface.FIG.10

2.Apply minimum pressure to work surface, to allow the tool to operate at high speed.

3.Maintain a 5° to 10° angle between the tool and work surface.
