®

 23-198 (6 in.) or 23-199 (8 in.) Grinder has 

convenient on-board tool storage for the dressing tool 

provided. The tool holder, shown in Figure 3, is located 

on the rear of the grinder base.

Prior to using your grinder for the first time, it is 

recommended that you check the tightness of the arbor 

nuts. To check the tightness on the arbor nuts, do the 

following:

1.  Remove the thumb screws (A) securing the outer 

face of the wheel guard to the tool frame. See 

Figure 4.

2.  Rotate the wheel guard to free it from the retaining 

screws and remove guard.

3.  Raise both wings of the arbor nut.
4.  Firmly grasp the wings of the arbor nut (B) with one 

hand while using the other hand to keep the wheel 

from moving. See Figure 5. Tighten the arbor nut as 

far as you can.

NOTE: You may also use the 13mm flat wrench 

(provided) positioned on the flat of the arbor shaft, 

(located between left side wheel and motor) to keep the 

shaft steady as you tighten the arbor nut.
NOTE: The arbor nut on the right side of the machine 

tightens by rotating it clockwise, the arbor nut on 

the left side of the machine tightens by rotating it 

counterclockwise. 

5.  Fold the wings of the arbor nut back to their original 

position so that they lay flat against the thick outer 

flange, then re-attach wheel guard.

6.  Repeat process for other side.  

NOTE: As you use your grinder, the force and direction 

of the wheel will cause the arbor nut to tighten 

automatically. However, it is recommended that your 

periodically check the tightness of the nuts as part of 

your regular tool maintenance.
