The trowel blades can be pitched for various finishing 

operations with the two rocker switches located on the left 

control panel next to the left joystick control (Figure 20).

Smart Pitch™ Mode

When the Pitch Mode Switch is in the Smart Pitch™ position 

(indicator light on), the twin-pitch and left-pitch switches 

operate as follows:
1.  When the Twin Pitch Switch (3-position, center off) 

is pressed (up or down), the right and left hand rotor 

pitch are changed and then the left hand rotor pitch is 

synchronized to the right hand as follows:
a.  The Twin Pitch Switch (up or down) causes the RH 

Pitch (up or down) Coil and LH Pitch (up or down) 

Coil and Pitch Dump Valve Coil to be actuated 

changing the pitch of the blades.

b.  When the operator achieves the desired pitch on 

the right hand blades and releases the Twin Pitch 

Switch, the LH Pitch (up or down) coil and Pitch 

Dump Valve Coil are actuated until the calibrated 

LH Pitch Position signal matches calibrated RH 

Pitch Position signal (.010” by Default). During this 

time the Pitch Mode Light will flash (.1 s on, .1 s off).

2.  When the Left Pitch Switch (3-position, center off) is 

pressed the pitch on the left rotor will be changed, while 

the pitch on the right rotor remains constant. The Pitch 

Mode Light will turn off, to indicate pitch function is in 

the unsynchronized state

TWIN-PITCH

SWITCH

LEFT-PITCH

SWITCH

MANUAL Mode (Pitch Mode Light is Off)

1.  When the Twin Pitch Switch is pressed (up or down), 

the pitch on both rotors will be changed simultaneously 

but non-synchronously.

2.  When the Left Pitch Switch is pressed the pitch on the 

left rotor will be changed, while the pitch on the right 

rotor remains constant.

PANNING Mode

When both the Twin Pitch Switch and Left Pitch Switch are 

pressed in the down position and held for preset period (5s 

by default), the machine will enter Panning Mode.
1.  The RH Pitch DN Coil and LH Pitch DN Coil will be 

activated pulling the yokes upward against Retracted 

Cylinder Stop, deactivating the pitch system, and 

allowing the blades to float for panning.

2.  The Pitch Mode Light will flash (.9 s on .1 s off) when 

in this mode.

3.  Machine remains in this mode until either the Twin 

Pitch Switch or Left Pitch Switch is activated in the 

upward direction.

 NOTICE

Moving the switches forward increases the pitch while 

moving them backward decreases the pitch.

 NOTICE

Momentarily depressing the Twin Pitch Switch will re-

synchronize the pitch.

 NOTICE

IMPORTANT! 

To get blades absolutely flat for using 

float pans, pitch them as follows:
Press and hold down both pitch switches until mode 

light blinks before installing float pans.
