Safety—Maintenance Precautions

Servicing and Maintenance Safety
NOTE: The locking pin is retained in the carrier’s tool box.
Understand all the control levers and their functions, note
all safety devices on the harvesting head and ensure they
are working properly.
Modifying, moving, or removing safety devices fitted to the
equipment could result in injury or death.
Where possible, lower all equipment to the ground; stop
the engine. Turn off power to the controller and isolate.
In the cab window, hang a “DO NOT USE” sign and, if
possible, lock the cab door.
When servicing or carrying out maintenance on the
harvester head, ensure the tilt frame is in the harvesting
or processing position, and the locking pin is installed.
If it is necessary to work on a raised boom or harvester
head, these must be supported and secured to prevent
the boom from lowering. The harvester head locking pin
must be fitted in the lock position.
Working in the “pinch area” or the “saw area” of the
harvester head while the hydraulic system is “active” could
result in injury or death. Always turn off the harvester prior
to commencing service.
Always remain on the ground or on a safe platform to
carry out repairs or maintenance. Standing on equipment
is a safety hazard, and could result in injury or death.
Do not stand under a suspended harvester head; doing
so could result in injury or death.
Attempting to alter or change the physical, mechanical,
or hydraulic operation of the harvester head during the
warranty period, without first consulting Waratah, will void
the carrier warranty.
Because of the size of some of the product components,
service personnel should always use proper lifting
procedures when removing any items.
Ensure the harvester head adjustments are correct and
the delimb arms and saw chain are sharp. Take extreme
care when moving around these areas. If necessary, wrap
all sharp items in a protective surface. Failure to do so
could result in personal injury.
Be aware of exposed parts such as the cylinder rods, or
hoses, and replace immediately if damaged.
When removing the main valve guard, always stop the
engine and lock the tilt frame. If the harvester head
suddenly stands up, serious injury may result.
If it is necessary to work on the hydraulic system while it
is under pressure (for example, searching for leaks etc),

always wear gloves, full protective clothing and search for
leaks using a piece of cardboard.
Always wear approved eye protection while visually
checking hydraulic leaks. Failure to do so could result in
injury or death.
Hydraulic oil under pressure can easily penetrate skin.
In this instance, fluid must be removed immediately by
a physician.
Always reduce the hydraulic system pressure to zero
before attempting to work on any hydraulic component.
Hydraulic oil becomes hot during operation; do not allow
hydraulic oil to come into contact with the skin, as it may
cause severe burns.
Care must be taken when handling valves. The electrical
controls and solenoids are not intended for carrying.
Check the hydraulic oil regularly and add oil when required.
Improper disposal of fluids can cause irreversible harm to
the environment. Find out the proper way to dispose of
waste from an environmental agency.
Following maintenance, replace all guards and safety
devices securely before attempting a restart.
Always ensure all service personnel and equipment are
clear of the agreed work zone. Failure to follow this
practice could result in injury or death.
