OPERATION
ADJUSTING DEPTH OF CUT
See Figures 4 - 5.
The depth of cut is determined by the distance from the bottom of the wheel to the tip of blade.
To adjust the blade depth:
Stop the engine and remove the spark plug wire or dis- connect from the power source.
Loosen the adjusting knob and move the wheel arm up to increase the depth or down to decrease the depth.
After adjustment is complete, tighten the adjusting knob securely.
Replace the spark plug wire or connect to the power supply and start the unit.
NOTE: Adjust the blade depth from 1/2 in. to 1 in. deep initially. Make a shallow cut to test the cutting depth. If the cutting depth needs adjusting, this should be done progres- sively until the desired depth is reached.
