Feed roller control
The C40 is equipped with a feed roller which facilitates the process of feeding material
into the machine. The feed roller is controlled via the yellow control bar which surrounds
the inlet table. The control bar has three settings:
1)
Reverse
2)
Neutral
3)
Feed
When the bar is fully pushed in, the feed roller will be set to reverse. When the bar is fully
pulled out, the feed roller will feed material. The neutral position lies between the reverse
and feed positions.
Automatic Feed Controller (AFC)
The feed roller is fitted with an electronic automatic feed control system which is designed to limit the feed rate of material into
the machine in order to prevent the engine from stalling.
This system eliminates the need to control the speed at which the branches are fed into the chipper manually. A sensor detects the
RPM of the rotor; once this speed drops to a pre-set level the feed roller stops and the branch stops feeding into the machine. The
engine then picks up in RPM and once it reaches a pre-set speed the feed-roller will start feeding again. The feed roller will also
reverse back slightly after stopping (reducing the friction between the wood and knives), resulting in a quicker engine recovery.
The feed roller will only work once the engine is turned on and the engine has reached full throttle after engaging the rotor. If the
green LED light on the AFC controller is flashing this indicates the feed roller
isn’t turning. When this changes to a solid green light
(when the engine reaches maximum RPM) the feed roller will be operational.
The AFC has 19 different pre-set positions at which the feed will stop.
Adjusting the AutoTrip setting:
1.
Turn the ignition key into the ‘ON’ position. Alternatively, this can be adj
usted when the machine is in operation.
2.
The version number will initially be displayed on the LCD display, wait until this clears.
3.
Push the ‘Menu’ button once.
4.
Adjust the AutoTrip
setting down using the ‘Menu’ button or up using the ‘Set’ button. There are 19 different positions at
which the feed will stop. At setting 1 the engine is dropping further in RPM, whereas at setting 19 the engine is only
dropping marginally in RPM before the feed roller stops. Adjust to a setting which is most suitable to you. Once adjusted
the screen will return to the hour meter / tachometer display after five seconds, saving the desired setting.
If there are any problems with the electronic automatic feed system, the chipper can be used with the auto-feed disabled. To
disable auto-feed, adjust the AutoTrip setting down to 0 or up to 20.
WARNING!
Be careful using the machine with auto-feed disabled as the machine can be stalled easily.

The engine LED panel has a self-contained engine safety shutdown system as well as a number of warning indicators.
