Support

Which type of vegetation can you work on with this machine?
This machine's petrol engine is very powerful. The structure of the blade and the distance between the teeth provide a high cutting ability. The combination of these factors allows you to tackle large hedges with dense vegetation and thick branches.
What should I do when it is not being used?
During the times when it is not being used, we recommend you empty the fuel tank, clean the teeth of the cutting element and place the machine in a safe place, ensuring you protect the blade within the storage area.
Do the cutting blades need maintenance or sharpening?
Cutting hedges leads to detritus and dirt building up between the blades, an issue which without the necessary maintenance can lead to a loss of cutting performance.
After each period of use, you should therefore clean and oil the hedge cutting blades, ensuring you work with the machine in full safety in a horizontal position, laid steadily on the ground. The blades can be cleaned with a dry cloth, using a brush if needed to remove more stubborn dirt. The blades can be oiled by applying a thin layer of specific oil (Stiga recommends using non-polluting products) along the upper edge of the blade.
Please see the user manual for more information on this point.
The blades seem to be working as if they are not clean or fluid. What might have happened and what should I do?
Where the blades tend to catch and you notice a reduction of cutting performance, possibly along with more blade noise, you must check the cutting element.
If the problem persists even after cleaning and oiling the blades, the solution is to sharpen them.
For reasons of safety, this is best performed by an authorised Stiga vendor. Once sharpened, the cutting system will return to working precisely and fluidly.
Lastly, please note that an excessively worn or damaged blade must not be sharpened but always replaced. Again in this case, the Stiga vendor network is always available.
