Set-Up: Correct position of micro switches
1. Place rear roller on the ground
2. Ensure the locking pins (fig.1) are installed into the Autopilot with the arm
fully lowered
3. Engine turned off, key removed, and PTO disengaged.
4. Slacken
bolt (“A” fig 2) and adjust cam plates until they are flush on the top.
5.
Slacken screws (“B” fig 2) to adjust switches; the lever arm must rise on the
cam as shown sufficiently to make the circuit. The switch will give an
audible click, if necessary, bend the lever arm towards the cam to ensure
the switch makes a circuit.
6. Remove the locking pin from the Autopilot and raise the main arm and rear
roller off the ground 0.5 m, now check the opposite switch has risen and the
other cam and the switch has made a circuit.
7. Turn on the Autopilot, the arm should rise if the arm head was fully lowered
or drop if the rear roller is off the ground, and the 2 switch arms should
come to rest in the valley between each cam peak.
Warning
Ensure the engine has stopped and the key is removed, the PTO is disengaged, handbrake
secure, and the head is firmly on the ground before attempting any servicing, maintenance or
adjustment.
