ADJUSTING THE CUTTING EDGE ANGLE

The edge angle can be varied plus or minus via the adjusting crank.  A 

clockwise rotation of the crank will lower the wheel into the work table 

resulting in a greater than 30° angle.  A counter-clockwise rotation of the 

crank will raise the wheel resulting in a lesser than 30° angle.

SHARPENING STRAIGHT

(OR CONVENTIONAL) BLADES

Use the 1” wide grinding wheel for highest performance.

DO NOT BE INJURED BY THE BLADE

MAKE SURE YOU WEAR SAFETY GOGGLES & GLOVES

1.  Securely locate the flat worktable over the rounded curved blade  

 

worktable and clamp with the vice grip.

2.  Switch to “ON”

3.  Adjust the grinding wheel crank to come in contact with the work  

 

table.  The more you cut into the work table the steeper the edge 

 

angle.

4.  To sharpen the blade, place it on the work table of the grinder. With  

 

your left hand provide the blade with a firm downward force to  

 

keep constant contact with the work table.  Also use your    

 

left hand to push the blade into the grinding wheel.  Then use your  

 

right hand to provide the back and forth motion to slide the blade 

 

against the grinding wheel (if you are left handed, just do the oppo-

 

site.)  The back and forth movement should be the length of the 

 

desired blade edge being sharpened.  The force pushing into the 

 

grinding wheel should be substantial, resulting in a continious stream 

 

of sparks from the grinding wheel.  The grinding process should be  

 

continious without interruption, until finished.

3.  Check to make sure the blade is straight (not bent) use the MAG-1000 

  Blade Balancer.

WARNING

Do Not attempt to straighten a 

hardened blade.  You may create 

fractures not visible to the eye.

REPLACE ALL BENT BLADES
