Hi Sam1 Thanks for getting in touch. There are a number of variables that determine an overall runtime, things such as which sized (Ah) battery, application, what is being trimmed ect? all affect this.

Hi Skippy Phil, Thanks for getting in touch. We don't really suggest removing the blade assembly as this is configured to the motor. However, for maintenance such as sharpening, ensure the battery is removed, your hedge trimmer is secured in a vice and correct protection is worn (safety glasses & a pair of gloves). To sharpen the blade we suggest using a flat file and filing in a downwards motion across the angle of the blade (Similar to sharpening a mower blade). Sharpening should only be completed in the downwards direction i.e away from your body if looking at the unit from above. Repeat this action for each of the teeth on the blade. After completing all the teeth we suggest coating in a vegetable-based oil/ lubricant to avoid rusting as well as protecting your plants.
