Forest Works Managers - help on what checks the contractor should be carrying out

As an FWM you could use the FISA checklists available in FISA Technical Note 003 – Inspection of Work Equipment and Machines to help go through checks with the contractor of the type of machine (and chainsaw) checks that should be undertaken.

Chainsaw PUWER checklist and an example Machine daily and weekly inspection record are also available on the link.
