Control Panel Diagram
Roller control box - is the control box above the feed opening of the chipper funnel. Its function is to control
the feed rollers. The feed rollers draw material into the machine.
It does 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
control buttons.
RED SAFETY BAR TEST
To ensure the safety bar is always operational it must be activated once before each work
session. The rollers will not function until the bar is activated. This procedure must be
repeated each time the ignition is switched off.
GREEN BUTTON
= Forward feed - Push the button once - this activates the rollers and will allow you
to start chipping (if the rotor speed is high enough).
RED BUTTON
= Emergency stop - This button stops the rollers from feeding. It overrides all other
buttons or bars and will not allow the other buttons to function until it has been reset. To reset, pull out until
it returns to its original position. The forward and reverse buttons will now function.
BLUE BUTTON
= 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 button. You do not have to press the STOP button before
pressing the GREEN FEED button to recommence feeding.
