7.  Line up the straight edge along the outside face of both pulleys as shown in the 

drawing. 

 
8.  Misalignment will show up as a gap between the pulley face and the  

straight edge. 

 
9.  Make sure that the width of the outside land (Area between the belt and the edge 

of the pulley) is equal on both pulleys. 

 
 

D. Depth Control

 

 
The cutting depth is controlled by a chrome turn handle.  It is located next to the 
push handle base, easily accessible from the rear of the saw.  The handle must first 
be unlocked before it can be turned.  It is locked by a black knob located on the 
operator’s left side of the hand wheel near the base of the handle.  This knob must 
be turned counter-clockwise to unlock the handle.  Once unlocked rotating the 
handle clockwise will lower the cutting blade.  Rotating it counter-clockwise will raise 
the cutting blade.  When the proper cutting depth is achieved by reading the depth 
gauge, relock the turn handle to ensure a constant cutting depth throughout the cut. 
 
The depth gauge can be found further down the shaft of the turn handle.  This gauge 
will already be preset for an Ø10" blade, but it still must be calibrated by the user 
since blade diameters may vary.  When using an Ø8" blade, the gauge must be 
readjusted from an Ø10" blade to an Ø8" blade.  Simply loosen the black knob found 
near the collar of the gauge and slide it accordingly to achieve the proper reading. 
 
The collar used to support the turn handle's screw should be checked after each use 
to make sure it is lubricated and turning freely.  If more lubricant must be added, 
NLGI #2, aluminum complex type grease is recommended. 

 
 

E. Cleaning

 

 
It is recommended to wipe all concrete dust off of the unit after each use.  Once a 
month blow the motor and motor fan off with compressed air.  Do not pressure wash 
the motor, switch boxes, electrical connects, bearings, belts, or bellows as damage 
by occur.  Damage caused by pressure washing is not covered under any warranty.
