MOUNTING NON-HUBBED WHEELS				G1
WARNING: Turn off and unplug the
tool before making any adjustments or
removing or installing attachments or				D
accessories. Before reconnecting the
tool, turn the switch on and off as
previously described to ensure that the
tool is off.
Depressed center Type 27 grinding wheels
must be used with included flanges.
NOTE: The stamped steel quick-change
backing flange (G2) is for use with D28140,				H
D28144 and D28144N for Type 27 grinding
wheels only. Refer to page 6–8 for more				1/4" WHEELS
information.
				(6.35 mm)
1. Install	the	stamped	steel quick-
change backing flange (G2) (D28140,				threaded clamp nut
D28144, D28144N only) for Type 27
6” wheels or the quick-change backing
flange (G1) for all other non-hubbed
wheels on spindle (D) with the raised				Quick-Change
section	(pilot)	against	the wheel. Be
				backing flange
sure the backing flange recess is seated
				1/8" WHEELS
onto the flats of the spindle by pushing
and twisting the flange before placing				(3.17 mm)
wheel.

2. Place wheel against the backing flange,	threaded clamp nut
centering the wheel on the raised
section (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 sec- tion (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.While depressing the spindle lock button, tighten the clamp nut with a wrench.

5.To remove the wheel, depress the spindle 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.

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.

4. Continuously move the tool in a for- ward 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 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. For deeper cutting with a Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart
