•Never adjust blade angle of HCA while standing
•Only adjust cutting angle with HCA resting flat on the ground, with the engine stop switch in the "STOP" position.
•Adjust cutting angle by moving locking lever (A) up. Depress blade indexing lever (B) and change blade angle with rear cutter assembly handle. Release indexing lever into notch. Move locking lever down to completely engage internal gears.
IMPORTANT
Locking lever (A) does not secure gear box angle setting. Moving lever in the down position reduces internal play in the gear box. Do not over tighten castle nut (C) to insure gear box angle setting tightness because damage to internal gears will occur. If the lever is loose or very tight, adjust nut (C) for snug 90° movement.
