What Will I Learn?
  • Identify, inspect and use the safety features of a chainsaw. Select the right tools and perform all end user maintenance operations on a working chainsaw.
View Curriculum
  • Ideally you will have your own chainsaw and access to the basic tools identified in the lecture 8.

This course will teach you to care for and maintain every wearing part on your chainsaw, from the guide bar to the chain and sprockets, fuel and air filters, starter mechanism, clutch and chain brake. The course is predominantly video based, with detailed descriptions and demonstrations of all the operations you will need to perform to understand your saw and keep it in top working order, whatever duty you put it through. The course will take about four hours to view all material from start to finish but it is designed to be modular so that you can use each individual lecture as a "how to" before you go ahead and perform each job on your own saw yourself. The course is split into five main teaching sections and introduces you to a course overview, the right Personal Protective Equipment (PPE), how to select the tools for your job, each individual maintenance process on the saw and a specific section devoted to chain care, maintenance and sharpening. There are quizzes in each section to help you check your progress and by the end of the course you will have covered a syllabus which professional chainsaw operators have to fulfil to successfully pass a UK industry standard assessment in chainsaw maintenance. Over the life of a saw, this knowledge will save you more money in maintenance than the saw costs to buy new and will ensure you are capable of extracting the highest cutting performance, accuracy and quality possible from your machine.

Who is the target audience?
  • This course is intended for anyone who owns a chainsaw or is about to acquire one. It is designed to teach an absolute beginner how to look after and optimise a chainsaw and equip anyone with the skills they need to maintain their chainsaw to a commercial standard without the bills that come from approved maintenance agents. Equally the course is ideal as a brush up for anyone with existing maintenance skills.The course is not for anyone with a non running machine and there are no pre entry requirements. If you can hold a spanner, this course is for you.

Knowledge Applied is Power.

My initial professional background hails from the construction industry where I worked for a railway civil engineering contractor for seven years. My work in that field spanned, bridge assessment and maintenance works, surveying and construction project management and I have lectured at the University of Central England in the design of structural elements for the award of the BTEC Higher National Certificate in Civil Engineering Studies. My attention was swayed towards the air transport industry in the late nineties and I spent the latter part of that decade training and qualifying as a pilot. I am a qualified flying instructor for the Private Pilot’s Licence and several other associated flying ratings. I have instructed on the RAF Central Flying school cadet scholarship programme and I have been an airline captain for a UK regional airline for the last ten years. For many years I harboured an unanswered curiosity for Arboriculture, particularly the aerial access and chainsaw operations. In 2010 I negotiated a part time contract with my airline employer so that I could train as a tree surgeon. I was mentored by one of the best trainers and operators in the UK industry, whose experience spans two decades, helping to set industry standards and codes of practise as well as performing an assessment function for the National Proficiency Test Council. I qualified in 2011 in chainsaw maintenance, cross cutting and felling, climbing and aerial rescue, and chainsaw operations from rope and harness. I now split my time between flying and subcontract works in arboriculture for my good friend and mentor who provided my training. I quickly realized how many people own and use chainsaws but do so without any formal instruction on the care of their machine. I also knew, from experience, that for the sake of a few hours instruction a chainsaw can be a valuable asset for life or a redundant relic just weeks after purchase. With my background in technical disciplines, teaching, both practical and theoretical subjects and industry specific knowledge I hope to have produced a valuable course which will bridge the gap between professional industry training and the domestic chainsaw owner/operator which will confer value tenfold in excess of its cost.
