  2. Activate Traffic Controller, and mobilise required machinery/equipment to work site.
  3. Execute pruning of the whole tree and cutting of branches shall only to be carried out for branches size not more than 50mm in diameter for area which near to public/traffic. In all event of tree cutting, sky lift must be used and only for chain saw operator. Using of sky lift for lifting or lowering of loads is prohibited.
