Feed roller control
The feed roller is controlled with 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 Control
The electronic automatic feed control system controls the feed roller and improves operation by:
✓
Keeping the engine RPM at optimal speed and power
✓
Preventing the engine from stalling when overloaded
✓
Assisting with clearing blockages
This system eliminates the need for the operator to control the speed at which material is manually fed into the chipper. A sensor
detects the speed of the cutting rotor, once this speed drops to a pre-set level, the feed roller stops the material feeding into the
machine. The engine then recovers to higher 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 quicker
RPM recovery.
The feed control can be set to 6 different AutoTrip levels from 1 to 6 or be disabled (OFF). Setting “1” is the default facto
ry setting
which allows the engine to drop the
most in speed before pausing feeding. Setting “6” allows the engine to drop
the least in speed
before pausing feeding. Setting “OFF” will disable automatic feed control and the engine may stall if it is overloaded. If th
ere are
any issues with the electronic automatic feed system, the chipper can be used with the auto-feed disabled.
WARNING!
Be careful using the machine with auto-feed disabled as the machine can be stalled easily.
