Pulses per revolution. On magnetic pick-up machines, this setting will be the number of
teeth on the gear or sprocket it is reading. On alternator pick-up machines, the setting will
need to be obtained from your local dealer or Bandit Industries.
Magnetic pick-up, also called pick-up probe. This is normally located screwed into the
 ywheel housing on the engine block. It can also be found on the clutch housing or chipper
shaft. See Figure 1.
This will normally be located on the infeed hopper of the machine. It can recognized by a
valve with two solenoids bolted on a square block. The solenoid is approximately 2-1/2”
(63.5mm) diameter x 2-3/4” (69.9mm) long. It will have two wires coming from it or on the
newer machines it will have a connector with a light screwed to it. The feed coil must have
power (indicated by the light in the connector) for the feedwheels to feed and pull material
in. See Figure 4.
Electronically activated to produce a magnetic pull which shifts the spool inside the hydraulic
valve. Shifting of the spool changes oil  ow direction from operating forward or dumping oil
to tank.
High or HI is the setting when the feedwheels will turn back on (feeding operation).
Low or LO is the setting when the autofeed will reverse (if equipped) the feedwheels and
then turn the feedwheels o󰀨 .
Amount of time in seconds the feedwheels will back the wood away from the cutter
disc/drum. Normally this will be set at 180 milliseconds (IEC) or .3 seconds (LOR).
