OPERATING INSTRUCTIONS

DELIVERY

All Timberwolf TW 280TVGTR 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.

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.
Control Box Diagram
There are two control boxes, located on either side of the
feed tray.
Note: Emergency Stops shown are only included on the
Timberwolf Safety Plus Kit model.

AUTO CONTROLS

The no stress unit controls the feed rate of the material going into the chipping chamber. If the engine speed is below the
predetermined level, the no stress 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.

EMERGENCY STOPPING

There are two ways of stopping the TW 280TVGTR chipper in the event of an emergency.
Stopping the Rollers
Activating the red safety bar will stop the rollers immediately. The rotor will still be turning, the engine must be powered
down to stop the rotor. Turn off the engine ignition key. To restart the rollers, just push the green forward or blue reverse
feed control.
Stopping the Engine
Should the engine 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.
Stopping the rollers and the engine: Should the entire machine need to be stopped in an emergency, activate
one of the red emergency stop buttons positioned on top of the funnel or on either sides of the feed tray.
This function kills all power to both the engine and the rollers, bringing the machine to a complete stop.
The engine cannot be restarted until the button is restored to its original position and the main ignition
switch is turned off to reset the machine. Before disengaging the emergency stop button, inspect the
machinery to determine the reason for activation.
