Feed Sensor Instructions
The feed sensor monitors the chipper rotor RPM to maximize chipping
efficiency. The low RPM setting is the rotor speed when the feed roller stops.
The feed sensor restarts the feed roller when the chipper rotor RPM reaches the
return operating speed. This ability to automatically stop the feed roller prevents
the engine from overloading and stalling.
• Engine Models: The feed sensor arrives programmed at the factory
to the following recommended settings.
low= 1650 RPM
normal= 2000 RPM
high= 0
return= 1675 RPM
poles= 1
• PTO models: Set feed sensor to above recommended factory settings.
Refer to the following page for instructions.
The feed sensor is energized when the chipper is started. Logs begins to feed as
the chipper rotor RPM reaches the "return" setting. The feed sensor continues to
monitor the chipper rotor speed during use.
• The feed sensor is equipped with an hour meter to track hour usage.
Stop the engine and make sure the chipper blades and all moving parts are
completely stopped before resetting the hour meter.
