How to Replace Your String Trimmer String Line Head

The new Hover Trimmer String Trimmer Line Replacement Kit Fits Easily Onto Any Straight Shaft Weed Trimmer Machine Measuring Up To 28mm In Shaft Diameter. Simply remove the existing string line trimmer head and replace with the easy fit Hover Trimmer Kit replacement head.

Please NOTE: Read the manufacturer's instructions supplied carefully and pay close attention while operating the Aero-blade.

Before beginning work with the Hover Trimmer, warm up the trimmer motor for around 2 minutes. Then accelerate the engine for 5 seconds before putting the blade parallel to the ground. The propeller blade will create the anti-gravity propulsion that keeps the blade at 2-3 cm parallel to the ground on a cushion of air. Upon operating the trimmer engine at a consistent velocity, this results in reduced fuel consumption.

DO NOT use rapid scything movement (more than 10/20 cm) as this can be dangerous and cause blade damage. Take responsibility and operate weed trimmer machines with care and attention at all times.

To maintain PULVERIZATION results, keep the blade clean and sharp; slightly tilt the blade in the direction of the movement.

Please DO NOT use a warped, cracked, broken or damaged blade. Always operate the Hover Trimmer Application with a maintained cutting blade.

The rotating Aero-blade must not come in contact with stones, metal or hard objects, as this can cause blade damage.

If the Aero-blade starts to shake or vibrate, turn off the engine and check the whole unit. Do not operate it until the trouble has been properly corrected. Follow these instructions: (a) Read the manufacturer's instruction manual (b) Check if the blade is properly assembled and firmly tightened. (c) Check if the blade is balanced by starting the machine and running the engine at full acceleration for around 1 minute. If vibration is still present please stop the machine and carefully remove the blade and insert the small red circular plug provided into the blade hole (See below Fig 28 above). This should eliminate any previous vibration issues and the Hover Trimmer machine can now be operated normally.
