Do Hedge Trimmers Need Oil?
Yes, hedge trimmers need lubrication to keep the friction between the blades low to prevent excess heat which can bend the trimmer’s blades. Unlike chainsaws, hedge trimmers do not have an oil reservoir, therefore the oil is applied directly to the trimmer blades.
What type of Oil Should I Use?
You can use any machine lubricating oil but here are a few which we recommend.

Ballistol Multi-Purpose Oil, Aerosol Spray
Ballistol Multi-Purpose Oil, Aerosol Spray is a popular lubricant for many applications. This is a common lubricant used for firearms. It is made to withstand heat and will penetrate really well.
This is my favorite lubricant and I use it on all my power tools when I feel they need some help. To apply, spray or apply the oil to your hedge trimmer blades generously and then wipe off the excess with a cotton rag. Once again, you don’t need to be too careful about where or how much you use because these lubricants will penetrate the areas between the blades as you run the tool.
You also don’t need to wear any special gloves to apply this one since it does not have carcinogens.

Can I use WD-40 to lubricate my hedge trimmer?
Do not use WD-40 to lubricate your hedge trimmer. WD-40 is marketed as a household lubricant, not for lawn equipment. WD-40 does not have the required lubricants or rust inhibitors to protect your hedge trimmer.
Because the formula is a secret, the MSDS sheet does not provide sufficient information to know the oil viscosity, rust inhibitor additives, or lubricating additives used in WD-40, WD-40 has also been shown to be a poor lubricant for machinery (source). It does not do well under the conditions present of a hedge trimmer which is of high friction and heat, similar to bearings.
Additionally, I have found that WD-40 attracts dirt more than it lubricates. I learned this lesson the hard way and had to throw out my bearings because the dirt and sand destroyed them.

How do I Lubricate My Hedge Trimmer?
You can apply the oil directly to the hedge trimmer blades, whether it is a spray or drop style applicator does not matter. You can further clean the blades by using an old cotton t-shirt, applying oil to the shirt, and rubbing it on the blades making sure to work free any grime.
How Often Should I Lubricate My Hedge Trimmer?
You should lubricate your hedge trimmer before and after every use. Lubricating before ensures smooth operations. Lubricating after cleans the blades and prevents rust.
Rust is the oxidization of metal and this is accelerated when metal is not kept clean and dry. The moisture from the plant’s residue has sufficient water to rust your hedge trimmer blades if not cleaned properly.
Be sure to keep your tools clean and dry if you wish to prolong their life.

I just bought a Black and Decker battery operated hedge trimmer. There is absolutely no information or Instructions to oil or lubricate the cutting bar. Does the bar need lubrication? Why did B & D not include this in maintenance instructions.
Hi David,
The short answer is, “not yet.” Since your hedge trimmer is so new it won’t need lubrication for a while. It would be best to oil it at the end and beginning of every season to minimize friction and heat between the blades as well as providing a protective coating to prevent rust. Certain things may accelerate the need for oil such as making contact with dirt or developing rust on the blade from excessive moisture.
Why B&D does not include these instruction? Because it would double the life of your tool and therefore you would not buy a new hedge trimmer sooner.
Thanks for your question,
Angel
Ever heard of something called Fluid Film? I’ve been finding a lot of posts/comments talking about how great it is for lubricating the trimmer blades.
Hi Daniel,
I’ve not heard of Fluid Film, it very well may be really great. Give it a try and let us know how you like it. There are a great deal of different types of lubricants you can use on your hedge trimmer and other tools. The important piece is that you do apply lubrication to your hedge trimmer and don’t rely on WD-40, since it’s not really a lubricant.
Thanks,
Angel
Hello again, Angel.
I finally got a chance to try Fluid Film on my trimmer. It seemed to work fine, although I have little experience with hedge trimmers, so that may not tell you anything useful.
FF turned out to be pretty easy to find. Most parts stores (O’Reilly, NAPA, Auto Zone, etc) seemed to have it, although it was a bit expensive. One weird thing was that had to be shaken up, and the can had a ball rattling in side it, almost like a spray paint can, so who knows what is going on inside there. No evidence that is significant, but kind of odd.
