Lesson 1Dealing with hung-up trees and suspended loads: assessment, use of wedges, pull-lines, and mechanised assistanceThis section explains how to manage hung-up trees and suspended loads without entering danger zones. Learners will assess stability, use wedges, pull-lines, and machines, and know when to stop work and call specialist assistance in the field.

Learners will review helmets, eye and face protection, hearing protection, chaps, gloves, boots, high-visibility garments, and weather layers for local use.

It covers stance, saw placement, cut sequence, and safe working heights on slopes and uneven ground in Zimbabwe.

Learners will read compression and tension, place wedges, use levers or winches, and avoid standing in the line of movement when wood releases during operations.

Learners will plan the lay, mark and cut the notch, set hinge dimensions, execute the backcut, and use preplanned escape routes and communication signals on site.

The section covers immediate shutdown, securing the scene, checking for injuries, preserving evidence, and reporting requirements to supervisors and safety staff promptly.

Learners will practice carrying positions, engine shutdown rules, chain brake use, passing the saw to others, and navigating slopes, brush, and obstacles safely.

Learners will study bar tip control, grip and stance, chain selection, reactive forces, and immediate response actions when the saw begins to kick back during work.

The section covers lighting, visibility aids, modified communication, wind and lightning protocols, and when to suspend chainsaw operations for safety in varying conditions.

Topics include exclusion zones, radio and hand signals, tag lines, staged processing areas, and coordinating felling, skidding, and loading operations effectively.

Learners will practice wedge and lever placement, scrench use for adjustments, and safe fuelling and transport of fuel containers on site.

Learners will inspect safety features, verify chain tension, and practice ground and leg start techniques, including cold start steps and chain brake engagement daily.
