LOADING AND UNLOADING

•  Always disconnect from power source before transporting. 
•  Ensure blanks are installed in magnetic tooling pockets during transport. 
•  Loosen handle securing bolt to slide handle down for loading/unloading. Re-tighten 

the bolts when handle is at the desired height.

HANDLE ASSEMBLY

Handle adjusts in both height and angle. To make adjustments, complete the following:

1.  Loosen the handle bolt and adjust the handle to the desired length (Figure 1); re-

tighten bolt.  

2.  Adjust handle grip to desired angle and firmly secure (Figure 1.1).  
3.  Adjust handle to desired angle and secure with clip and support pin (Figure 1.2).

VACUUM PORT 

The machine has a dust collection port located at the rear (Figure 2A). Use a dust col-

lection hose that snugly fits either on the outside or the inside of the port. The dual short 

hose connection runs from the grinder deck to the ‘Y’ splitter (Figure 2B).

RUBBER DUST GUARD

Attaching

1.  Ensure machine is in upright position.  
2.  Attach dust guard (Figure 3), keeping as close to the floor as possible.   

Note: 

If dust is exposed when operating machine, stop machine and readjust 

dust guard.

CAUTION:

 HANDLE MUST BE SECURED WITH BOTH BOLTS; BE AWARE OF 

ROTATING WEIGHTS. FAILURE TO DO SO COULD CAUSE SERIOUS INJURY.

 MAKE SURE TO USE THE PROPER INDUSTRIAL HEPA DUST 

COLLECTOR BASED ON THE TYPE OF SURFACE APPLICATION. FAILURE 

TO DO SO COULD RESULT IN EMISSIONS OF HAZARDOUS PARTICULATES. 

ENSURE THE SYSTEM BEING USED COMPLIES WITH OR EXCEEDS OSHA 

RECOMMENDED STANDARDS. THE RUBBER DUST GUARD MUST BE SECURE 

AND COVER ALL THE WAY TO THE FLOOR SURFACE.

WARNING:

 NEVER OPERATE THE MACHINE WITHOUT THE RUBBER DUST 

GUARD PROPERLY IN PLACE. ENSURE DUST GUARD FORMS A SEAL FROM 

THE GRINDER DECK TO THE FLOOR. FAILURE TO DO SO COULD CAUSE 

SERIOUS HARM TO THE OPERATOR AND/OR THOSE IN PROXIMITY OF THE
