STOPPING THE ENGINE
Move the throttle lever to the ‘Tortoise’ to reduce the engine speed to idle. •
Leave the engine running for 1 minute. •
Turn the power switch to position 0. The engine should stop after a few seconds. •
Remove the ignition key. •
For more detailed information refer to the Engine Owner’s Manual.
Wood up to the recommended diameter can be fed into the feed funnel. Put the butt end in first and engage it with the
feed rollers. The hydraulic feed rollers will pull the branch into the machine quite quickly. Large diameter material will
have its feed rate automatically controlled by the no stress unit.
Sometimes a piece of wood that is a particularly awkward shape is too strong for the feed rollers to break. This will cause
the top roller to either bounce up and down on the wood, or both rollers to stall. If this occurs, press the
blue reverse
feed control until the material has been released. Pull the material out of the feed funnel and trim it so the chipper can
handle it.
Both feed rollers should always turn at the same speed. If one or both rollers stop or suddenly slow down it may be that
a piece of wood has become stuck behind one of the rollers. If this occurs, press the
blue reverse feed control and hold
for 2 seconds - then repress the green forward feed control. This should enable the rollers to free the offending piece of
material and continue rotating at the correct speed. If the rollers continue to stall in the 'forward feed' or 'reverse feed'
position push the red stop button, turn the engine off, remove the ignition key and investigate.
CONTROLLING THE ENGINE SPEED
Always start the engine with the lever in the ‘slow’ (idle) position. With the throttle lever in the ‘fast’ position the machine
is ready to chip. It MUST be fully pushed to the left to achieve a suitable working speed. If no wood is to be chipped for
a few minutes the throttle should be returned to the ‘slow’ (idle) position.
