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).
Locate the machine on firm level ground. •
Check machine is well supported and cannot move. •
Check all guards are fitted and secure. •
Check the discharge unit is in place and fastened •
securely.
Check discharge tube is pointing in a safe direction. •
Check the feed funnel to ensure no objects are inside. •
Check feed tray is in up position - to prevent people •
reaching rollers.
Check controls as described on page 11. •
Check (visually) for fluid leaks. •
Check fuel and hydraulic oil levels. •
For parts location see diagrams on pages 3 & 4.
DAILY CHECKS BEFORE STARTING
CRAWLER TRACK CONTROLS
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.
NOTE: ENSURE TRAY IS
ROTATED INTO THE
UP/CLOSED POSITION
PRIOR TO TRACKING TO
AVOID DAMAGE.
Track width adjustment is only possible with the track/chip control in
the chip position. The 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.
There are two tracking speeds which can be selected via the speed
selection switch on the control panel (5 kph or 2.5 kph). Speed can be
further controlled with the throttle. It is recommended that
manoeuvring in tight spaces, loading, unloading and tracking up
gradients should be performed in speed one. Speed two should only
be selected for tracking on level ground. The chipper can operate
continuously at a 20° incline and up to 10 minutes at 30° incline.
