Note: You may have to push down or pull up 
on one side of the table to make it even with 
the wheel.

2.  Remove  (2)  M5-.8  x  35  cap  screws,  (2) 

5mm flat washers, and (2) spacers shown in 

Figure 32, then remove the wheel guard.

Page 19).

4.  Place  the  dresser  tool  holder  on  the  pivot 

support,  as  shown  in 

Figure  33,  insert  the 

diamond dresser into the holder until the tip 
makes  contact  with  the  wheel,  then  tighten 
the  set  screw  in  the  holder  to  secure  the 
dresser tool.

5.  Move  the  dresser  tool  so  that  the  tip  is  just 

outside  the  wheel's  diameter,  then  turn  the 
grinder 

ON.

6.  Slowly  move  the  dresser  tool  across  the 

wheel, then back to the starting position two 
to three times.

7.  Lower the table slightly and repeat Step 6.

 

Note:  Several light passes with the dress-
ing tool will produce the best results with the 
least amount of wear or damage to the wheel 
or the dressing tool.

Grinding wheels have the capability of 

removing a lot of skin quickly. Keep a firm 

grip on the dresser tool and holder, and keep 

your hands a safe distance away from the 

spinning wheel.

Wheel Dressing

With use, the surface of the grinding wheel will fill 
with  metal  residue  and  grit.  When  this  happens, 
the wheel needs to be cleaned or “dressed.” The 
goal of dressing the wheel is to remove the con-
taminants and make the surface even and flat.

The dressing stone included with your grinder can 
be used to dress the wheel by carefully holding it 
against the spinning surface. However, the safest 
and  efficient  method  of  dressing  the  wheel  is  to 
use a diamond dresser (refer to 

Accessories on 

Page 24 for options).

To dress the wheel with a diamond dresser:

1.  Lower the table so that the grinding wheel is 

approximately 

1

⁄

4

"  above  the  table  surface, 

then make sure the top surface of the wheel 
is level with the grinder table.
