Engine Controls; Crawler Track Controls - Timberwolf TW 280TVGTR Instruction Manual

OPERATING INSTRUCTIONS

ENGINE CONTROLS

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 next to the engine stop switch
(see parts locator on page 3).

CRAWLER TRACK CONTROLS

The TW 280TVGTR is designed to operate in either chip or track mode, but not both at the
same time. The modes can be selected using the toggle switch located on the driving control
panel. The lift function to adjust the gradient and height of machine is available in both
modes.
Chipping Mode
Power is supplied for the chipping function. The feed rollers can be operated as detailed on page 9. The machine cannot
be tracked in this mode but the lift function is available to adjust the height and incline of machine. During any adjustment
power will be diverted from the feed rollers.
Crawler Track Mode
Power is supplied for the tracking function only - the machine can be tracked in this mode. The rotor and blades will
remain spinning, but the feed roller controls are inoperable, the lift function is available to adjust the TW 280TVGTR to
suit the terrain.
When Track Mode is selected the two track control valves may be operated. These have direct control over the track
relevant to the 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, on variable terrain
and while loading/unloading should be done with the engine on low speed.
Lifting Mode
Power is available for the lift function in both chip and track mode. The machine can be lifted by means of the two
control levers, each lever (left and right) controls the lift action of the corresponding track. From its closed position,
when the levers are moved forward, the track will move out horizontally before it lifts the machine - take care to allow
for the extra width and height when performing this function. To lower the machine, move the lever in the reverse
direction, the machine will be lowered first before the track is pulled horizontally back into the closed position.
NOTE: ENSURE TRAY IS ROTATED INTO THE UP/CLOSED POSITION PRIOR TO TRACKING TO AVOID
The inclinometer (positioned on the top of the feed
funnel) indicates the angle of incline of the chipper,
on the horizontal plane. The chipper can operate
continuously at a 20° incline and up to 10 minutes
at 30° incline.
