In general, use higher height settings to handle taller material and to cope with tougher cutting conditions. Use any trim- ming height for less demanding condi- tions. To adjust the cutting height:
1.The cutting line height can be changed when the wear cup is resting on the ground. If necessary, tip the unit back slightly for a better view (do not tip unit all the way back or motor oil may flow to the exhaust area and the engine may smoke for several seconds when restarted).
2.Use a 1/2" wrench to loosen both bolts (A, Figure
