OPERATING INSTRUCTIONS
The chipper is designed to operate in either chipper or crawler mode, but not both at the same time.
CHIPPING MODE
Power is available to the feed rollers. The cutting disc is rotating but the unit is stationary.
CRAWLER TRACK MODE
Power is available to the crawler tracks. The cutting disc is rotating but the feed rollers are stationary.
To switch between modes, a lever is operated (see diagram below). This is located on the driving
control panel (see parts locator on page 3). It is clearly marked.
When Track mode is selected the two track control valves may be operated. These have direct
control over the track relevant to each side of the machine. They are proportional valves, so increased
movement will result in increased track speed.
Tracking may be done at either high or low engine speed. Manoeuvring the
machine in tight spaces and while loading and unloading should be done with
the engine on low speed.
TRACK
CHIP
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 feed 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 speed.
There are three ways of stopping the TW 150VTR chipper in the event of an emergency.
STOPPING THE ROLLERS
-Activating the red safety bar will stop the rollers immediately. To restart the rollers, just push the green
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.
STOPPING THE ENGINE
Should the entire machine need to be stopped in an emergency, the red button on top of the engine
guard should be pushed. This will shut down the engine in the shortest possible time. The engine
cannot be restarted until the button is pulled out and the main ignition switch is turned off to reset the
machine.
NOTE: Ensure low safety bar on
low funnel is rotated into the ‘stowed’
(up) position prior to tracking to
avoid damage to the bar.

WARNING
NEVER LEAVE THE CHIPPER ON A SLOPE UNATTENDED.
Tracks
out
Tracks
in
For machines fitted with variable tracks, track width adjustment is only possible
with the track/chip control in the chip position. Track adjust handle is spring loaded
to the middle (see diagram, right). The more you move the handle, the more the
tracks adjust. To move the tracks outward, move the track adjust handle
up.
To
bring tracks inward, move the track adjust handle
down.
