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

information.

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
