Lock the Pilot Interlock Valve
WARNING
Ensure the pilot interlock valve is in the ‘LOCK’ position
BEFORE performing service or maintenance work on the
harvester head.
The pilot interlock valve’s ‘LOCK’ position minimises
the risk of accidental movement of the harvester head.
Personal injury or death may occur.

Some carrier hydraulic control systems include
interlocks, which will disable the carrier’s hydraulic
power when activated. These should be locked before
starting servicing or maintenance work.

Stay Clear of the Saw Chain
DANGER
XJ1197287—19—10JUL15
Do not stand or work in the cutting direction of the chain
saw while the machine is running. In the event of the
chain breaking, chain links can fly off the saw bar at high
speed. The chain shot hazard zone is approximately 15
degrees towards the rear of the sprocket and in front of
the bar tip. Keep personnel 90 metres (300 feet) away
from the harvester head during tree felling.
Servicing the harvester head with the engine running is
extremely hazardous. Turning off the carrier engine
removes the hydraulic power to the harvester head and
makes it safe for servicing.

Never Stand on the Harvester Head
WARNING
NEVER stand on the Harvester Head.
Remain on ground or on safe platform.
EXTREM CARE required around Delimbing
knives, chain saw and pitch areas.
DO NOT stand under Harvester Head.
Personal injury or death may occur.
XJ1299117—19—24JUN20
When servicing or carrying out maintenance, work from
a safe platform. Never stand on the harvester head. Its
surfaces are not designed for standing on: they have no
tread grip pattern embossed, and can become very
slippery. Nor is the harvester head stable. The link from
the arm/stick to the harvester head has freedom of
movement in four directions, and altering the balance
can cause the harvester head to move unpredictably.
The knife edges and saw chain are razor-sharp.
Grabbing hold of them or handling them without
protective gloves, or knocking into them can cause
personal injury. Keep away from the pinch area; the
harvester head can shift or move unpredictably.
Never rely on the boom cylinders or the arm/stick
cylinder to keep the harvester head suspended. Where
work on a raised boom and harvester head is required,
they must be supported and secured to prevent the
boom from lowering.

Keep Away from the Pinch Area
KEEP AWAY
XJ1197372—19—10JUL15
Extreme care is required around the upper and lower
arms to avoid being inside the ‘pinch’ areas. The
hydraulic cylinders can creep and move unpredictably if
a fault occurs. Servicing the harvester head with the
carrier engine running is extremely hazardous. Turning
