The engine management unit controls the feed rate of the material going into the chipping chamber. If
the engine speed is below the predetermined level, the engine management unit will not allow the feed
rollers to work in the forward “infeed” direction, until the rotor speed rises above the predetermined
level. At this point, the feed rollers will start turning without warning. The reverse function will work at
any engine speed.
The engine controls are in two locations. The engine ignition is on the
control panel in the centre of the machine, and the throttle lever is on the
bonnet (see parts locator on pg. 3).
This can be viewed through the wall of the tank.
Maximum and minimum marks are provided.

forward button or blue reverse button.
-Pushing the red Emergency button on the roller control box will also stop the rollers immediately.
The button will stay in the “pushed in” position, and will require resetting (pulling out) before being
able to restart the roller functions.
