RED SAFETY BAR
Do not rely on the red bar to keep the roller
stationary if it is necessary to clear or touch the
roller. Always switch off the machine and remove
ignition key before approaching the roller.
There are two control boxes, located on either side of the
feed tray.
MANUAL CONTROLS
Roller control boxes: a control box is located on either side of the feed funnel. Their function is to control the feed roller
whilst processing material. They do not control the main rotor.
RED SAFETY BAR: This is the large red bar that surrounds the feed tray and side of the feed funnel. The bar is spring
loaded and connected to a switch that will interrupt the power to the rollers. The switch is designed so that it only
activates if the bar is pushed to the limit of its travel. The rollers stop instantly, but can be made to turn again by
pressing either the GREEN FEED or BLUE REVERSE controls.

Red Safety Bar Test
To ensure the safety bar is always operational it must be activated
once before each work session.
GREEN FEED CONTROL: forward feed - push the feed control once -
this activates the rollers and will allow you to start chipping (if the
rotor speed is high enough).
BLUE FEED CONTROL: reverse feed - allows you to back material out
of the rollers. The rollers will only turn in reverse as long as you
keep pressing the feed control.
