Well done! You have completed your tree climbing and rescue course and now want to use a chainsaw in the tree. The chainsaw free fall techniques (CS39) course is all about making the right cut so no excessive damage is done to the tree whilst you are working in it. Therefore chainsaw free fall course is not about chop and drop or cut and chuck!
Using a chainsaw in a tree is not something to rush, it certainly needs consideration and thinking through. A healthy respect for the chainsaw is a must, you do not want to end up as a statistic?
No doubt up until now you have already probably been using a silky or chainsaw in a tree with some sort of supervision. But to make sure you stay as safe as possible in the future you will need to have the chainsaw free fall qualification. As a result of achieving the course it will provide you with:

Our 2-day chainsaw free fall CS39 techniques course is the perfect chance to:

You may have been asked by:

Other courses of interest to you
We tend to provide the chainsaws as you might not know what to buy until you have done the course. You wouldn’t want to spend hundreds of pounds buying a machine and finding it was the wrong one or one you didn’t like.
No, if it cuts wood it will be fine. There is no best chainsaw because it is down to personal preference and budget.
Only in extreme circumstances and if it is not possible to put in an additional anchor point. Above all it is about staying safe!
Yes, if you have passed the assessment for the tree climbing and rescue CS38 course. However, you may find that getting into a good cutting position a bit harder because you will be tired and have not had enough practise getting into position. Furthermore, the additional weight of the chainsaw can throw you out if your are a little inexperienced.
Yes, if it is in good condition and has relevant LOLER documentation with it.
No, it is only a free fall course. So the use of ropes for rigging is not required.
Not really but you do have to finish off the limbs with proper pruning cuts and observe the branch bark collar. The qualification itself doesn’t cover pruning in detail, because that is covered under Aerial Tree Pruning 21-07 (formally CS40).
If you have climbed before and feel confident then no, you don’t have to. However, this is done entirely at your own risk. Consequently, if you fail the assessment due to lack of training time, then that is your responsibility and we accept no liability for it.
No there is no requirement for spikes on the CS39. Due to the damage the spikes can do to the tree in the wrong situation.
The City and Guilds qualifications last for life. However, it is always good to check regularly to see if there have been any major changes that you should be aware of.
You are advised by HSE to carry out refreshers every 5 years. This maybe different depending on the company you work for, some have different frequencies such as the National Trust, which is every 3 years. Therefore, refreshers are important as they keep you up to date with changes within the industry.
Pre-requisites for CS39 are:
- chainsaw maintenance and cross-cutting 20-03 (formally CS30)
- felling and processing trees up to 380mm 20-04 (formally CS31)
- tree climbing and aerial rescue 20-13 (formally CS38)
Some suppliers will ask to see your certification. Similarly, there are far more that will not check and just sell you the chainsaw.
If you cut a branch and let it fall to the ground without limiting its descent by use of a lowering rope.
The cuts you will do on the chainsaw free fall CS39 course include:
- sink cuts
- step cuts
- handheld sections
No, however, there is a minimum requirement of 100mm or 4inches.
The unit covers basic pruning and how to identify branch bark collars and branch bark ridges, for more detail on target pruning you would need to attend Aerial Tree Pruning 21-07 (formally CS40)
