OPERATING INSTRUCTIONS
C190-0113 01.07.2019 Rev: 4.0
DELIVERY
All Timberwolf TW 230VTR machines have a full pre - delivery inspection before leaving the factory and are ready to use.
Read and understand this instruction manual before attempting to operate the chipper. In particular, read pages 5-6
which contain important health and safety information and advice.
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 feed control.
Control Box Diagram
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.
AUTO CONTROLS
The no stress unit controls the feed rate of the material going into the chipping chamber. When the rotor speed is
below the predetermined level the no stress unit will not allow the feed rollers to work in the forward direction. When
the rotor speed rises above the predetermined level the feed rollers will start turning without warning.
EMERGENCY STOPPING
There are two ways of stopping the TW 230VTR 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 or blue
reverse feed control.
Stopping the Engine
Should the entire machine need to be stopped in an emergency, the engine stop switch located on top of the engine
bay should be pushed. This will shut down the engine in the shortest possible time. The engine cannot be restarted
until the engine stop switch is pulled out and the main ignition switch is turned off to reset the machine.
