The Controls 

 
The depth control (see Fig. 4 and Fig. 5) is located on the right side of the handle assembly.  Figure 4 shows the control in the 
idle position and figure 5 shows the cutting position.  Turning the crank clockwise adjusts the cutting depth lower; counter-
clockwise rotation  of  crank  raises the cutting  blade.   Operator  must  be familiar  with  operation  of this  control  before  using 
roof cutter on the job. 
 
The throttle is located on the left hand side (see Fig. 6).  Lowering lever handle decreases the engine speed.  Raising the lever 
increases the engine speed.
