1.12 Pitch Adjustment
Different pitch angles are needed as you work the dif-
ferent stages of the concrete. See the drawing below.
When changing or setting pitch (angle of trowel
blades), set the desired degree of pitch on the left side
of the machine and then adjust the right side to match.
To increase the pitch, press the gray pitch control but-
ton (b) which is located on top of joystick towards the
inside. To decrease the pitch, press the pitch control
button (a) which is located on top of joystick towards
the outside.
