Understand the situation

Observation

Every operation begins with an examination of the tree, its balance, buttresses, apparent condition and immediate surroundings. This assessment helps anticipate constraints and prepare an appropriate decision.

Control the execution

The gesture

Felling quality depends on accurate cuts, sound chainsaw handling, proper worksite preparation and the ability to adapt the method to the characteristics of the tree.

The collective

Felling is part of a collective operation. Communication, safety, felling direction, protection of the remaining stand and coordination with subsequent operations concern the entire worksite.

02Field observations

Gaps become visible during execution

A procedure may be known without being applied consistently. Examining the work helps identify technical, equipment-related and organisational gaps that reduce safety, accuracy or efficiency.

  1. 01

    Incomplete assessment

    The tree, its surroundings and worksite constraints are not always examined with the required level of detail.

  2. 02

    Inadequate preparation

    Felling direction, escape routes, equipment and worksite organisation may be decided too quickly.

  3. 03

    Inconsistent equipment or practices

    Equipment availability, PPE use, communication and safety distances are not always consistent.

  4. 04

    Limited coordination

    Felling is not always sufficiently connected with winching, skidding and protection of the remaining stand.

03The FIT method

Observe, explain, practise, consolidate

The FIT approach combines assessment, explanation, demonstration, supervised practice and review of the result. It is adapted to operator skill levels, available equipment and site conditions.

  1. 01

    Observe

    Examine practices, worksite conditions, equipment and operator needs.

  2. 02

    Explain

    Clarify technical choices and demonstrate a method suited to the situation.

  3. 03

    Supervised practice

    Allow operators to apply the techniques with field support.

  4. 04

    Assess and consolidate

    Review execution, correct gaps and strengthen acquired skills.

04FIT areas of expertise

Expertise that can be mobilised according to the proposed framework

These capabilities may be mobilised through employment, an operational assignment, a professional collaboration, training or worksite support.

01

Controlled felling

Prepare and carry out felling using a method suited to the tree, terrain and subsequent operations.

  • assessment of the tree and its surroundings
  • selection and control of the felling direction
  • work-area clearance and preparation of escape routes
  • directional notch, hinge, holding wood and back cut
  • adaptation to buttresses, large diameters and specific situations
  • area control and communication
  • stump and result assessment
02

Chainsaw and cutting equipment

Cutting performance depends on the correct combination of machine, guide bar and chain, together with proper preparation and routine maintenance.

  • selection of a chainsaw and guide bar suited to the work
  • safe starting, handling, transport and shutdown
  • working positions and machine control
  • cutter sharpening and depth-gauge inspection
  • chain tension and lubrication-system checks
  • guide-bar, chain and sprocket maintenance
  • first-level diagnosis and referral to a technician when required
03

Felling equipment and PPE

Worksite preparation includes identifying, obtaining, making available and correctly using the required tools and protective equipment.

  • suitable felling wedges and striking tools
  • tools for clearing the work area and escape routes
  • sharpening and routine-maintenance tools
  • spare chains, common consumables and replacement items
  • fuel, two-stroke engine oil, chain oil and suitable containers
  • communication and first-aid resources according to worksite organisation
  • preparation of a coherent kit for each operator or crew
04

Safety and reduced-impact logging — RIL

Improve operational organisation while protecting people, the remaining stand and subsequent worksite operations.

  • risk assessment and the decision to stop an unsafe operation
  • work-area and escape-route preparation
  • communication and safety distances
  • control of access to the work zone
  • protection of the remaining stand and future crop trees
  • felling direction compatible with winching and skidding
  • damage reduction and operational coordination
05

Training and team support

Develop operator skills and strengthen supervisors' ability to observe, explain and correct field practices.

  • assessment of practices and needs
  • technical demonstration
  • supervised practice
  • individual assessment
  • direct field correction
  • support for crew leaders and forestry supervisors
  • follow-up and consolidation of skills

Fuel and lubrication

The two-stroke fuel and engine-oil mixture must be prepared according to the manufacturer's specified ratio and requirements, using suitable products, containers and methods.

Oil specifically designed for the saw chain and guide bar, with suitable tackiness, helps maintain a lubricating film throughout the chain's travel. It contributes to smoother chain movement, more fluid penetration of the cutting equipment into the wood and reduced friction, heat and premature wear of the guide bar, chain and sprocket.

Guide-bar maintenance also includes cleaning the groove and oil holes, together with inspecting and removing burrs when they appear.

  • compliance with manufacturer specifications
  • accurate measurement and preparation
  • use of clean and clearly identified containers
  • chain-oil delivery checks
  • exclusion of used engine oil and unsuitable lubricants
  • safe storage and transport of fuels and lubricants
05Operational progress

What field support is designed to strengthen

  • 01More complete assessment of the tree and situation
  • 02More consistent felling methods
  • 03Better control of chainsaws and equipment
  • 04Available and correctly used equipment and PPE
  • 05Stronger coordination between operations
  • 06Greater supervisory capacity to observe and correct
06Post-operation assessment

The result must be observable and explainable

Examining the stump and cuts makes it possible to review execution, understand gaps and turn the completed operation into a learning resource.
