February 2022 - Member query - Following the recent publication of FISA 608 Tree Shear & Grapple Saw, an enquiry was received relating to the application of LOLER in the guide and the need for a lifting plan, and if this had a bearing when using a forestry grab attached to an excavator as it isn’t referenced in older FISA Guides.  A review of the information provided  by HSE on the interpretation of LOLER in Forestry is a review topic on the FISA Plant & Equipment Working Group workplan. When this is complete more information on compliance will be shared with members and where required FISA guides updated. 

December 2021 - This FISA guide is new to the forestry industry and we welcome your feedback on the guide. If you have feedback, please email Your comments will be fed to the FISA Plant & Equipment Working Group and the guide will be reviewed in eighteen months’ time.
