General Operation
CAUTION: The harvester head should only be
operated by trained personnel. Failure to follow
these safety precautions can lead to risk of
serious injury.
The efficient operation of the harvester head depends
on practice and experience. The harvester head will not
operate to its full potential if the adjustments are not
correct and/or delimb and saw arms are not sharpened
properly.

Planning Area Preparation
Planning plays a decisive role in a mechanized timber
harvesting.
Successful planning utilizes previous experience.
Many aspects are considered when formulating a
harvesting plan. These include:
● Terrain
● Ground conditions
● Waterways
● Soil type
● Erosion control
● Species
● Stem density
● Stem form
● Undergrowth
● Access
● Roading
● Boundaries
● Historic sites
● Environmental areas
● Gas and transmission lines
● Public access
● Storage sites
● Landings
● Equipment to be used
● Staff ability
● Haul distance
These factors all determine the way a plan is formulated
to operate a safe, productive, and profitable harvesting
operation.
Site inspection is necessary before harvesting
operations commence. Ensure all members of the
harvesting team are aware of the constraints, hazards
and requirements of this harvesting operation.
Planned, regular site meetings need to be held to
ensure the conditions of the plan are being upheld, and
to address unforeseen aspects encountered by
operators.
Preparation
It is advisable that the operator has had experience
operating the Waratah harvester head before felling
trees.
The carrier needs to be in good condition, with clean
windows.
The cutting unit should be sharpened, tensioned, and in
good condition.
Test all controls before starting felling.
The carrier’s automatic idle should be turned off. This
may idle the carrier down when using the saw chain.
Determine the location of roads, waterways and
boundaries.
Before work begins, identify any additional hazards.
Before operating the harvester head, run all the
functions to ensure the hydraulic components have
been warmed up. If hot oil under high pressure runs
through cold components, the thermal shock can cause
excessive wear and/or damage.
