Figure 3 - Warning label - inspect blades before use

The right side edge of the dolly frame will serve as your blade guide.  This 
edge will line up with the innermost blade. The outer edge of the cut will be 
determined by how many blades/spacers are being used.  (6) blades using 
(5) medium .125 spacers will leave a cut approximately 1” wide.

CAUTION: 

The blade depth is approximate and not exact. Many vari-

ables affect the exact blade depth such as the exact diameter of a worn 
diamond blade. If an accurate depth must be cut, install the blade to be 
used with the motor in the OFF position. Place the MC-45 in a secure 
position that allows the blade to overhang and be visibly measured at 
full blade depth. An example would be blocking the wheels with the mo-
tor in the OFF position and lowering the MC-45 blade along side a street 
curb. This will allow a measurement from the bottom of the blade to the 
top of the curb.

WARNING: 

Breathable silica may be generated by use of this product. 

Silica can cause severe and permanent lung damage, cancer, and other 
serious diseases. Do not breath the dust. Do not rely on your sight 
or smell to determine if the dust is in the air. Silica may be in the air 
without a visible dust cloud. If air monitoring equipment for silica is not 
provided by your employer at your work site, you MUST wear appropriate 
respiratory protection when using or servicing the machine. Consult your 
employer and OSHA regarding the appropriate respiratory protection.
