STIHL offers a wide range of grass trimmers for domestic and professional use . These differ in various aspects such as power, drive type and handle type, as well as the mowing head supplied as standard. However, while the other characteristics mentioned are fixed, you can remove the heads installed on STIHL grass trimmers and replace them with alternative cutting tools. This makes them more versatile as you can tailor the tool to your task. A. No, only ProCOM headsets can be used in the mesh. If you have a DMR or walkie-talkie with Bluetooth speaker capability, ProCOM can be connected and used conveniently as a headset. In this case, the mesh intercom will still be functioning in addition to the DMR connection, but DMR messages will not be heard by other ProCOM users. In summary, TrimCut and SuperCut heads are particularly suitable for domestic users, while AutoCut is appropriate for use in private and professional settings, making it the perfect all-rounder. As well as being suited to different tasks, each type of head also requires a different procedure when it’s time to refill or entirely replace the trimmer line. Your trimmer head comes loaded with a spool of line which can be released a little at a time for use through several trimming tasks – but it won’t last forever. To replace it you can buy a new roll of line and refill your existing grass cutting head. With a high attenuation value (SNR 31) and active noise suppression, STIHL ADVANCE ProCOM headsets reliably protect against the engine noise of petrol-powered equipment. What’s more, an intelligent audio function means that incoming radio messages are prioritized and heard by the user, so that warning calls from colleagues can be heard clearly over any radio or music playing. Generally, there are three different ways to replace trimmer line in a STIHL grass cutting head, depending on the model type.

As headphones, these have a pretty incredible runtime that can keep you jamming for most of the week without needing to recharge. The actual sound quality could be better, but for working outside with loud equipment, we don’t see clarity as a primary concern. The ‘Connect’ button allows you to answer and hang up calls, as well as access the smart phone’s virtual assistant. The sturdy spring steel mesh visor allows up to 80% light visibility for a protected and clear view. Corresponds to EN 352, EN 397, EN 1731.A. STIHL do not recommend pairing ProCOM with other headsets that also use Sena technology. Although some Sena products may be compatible depending on the software version (supporting profiles can be found in the user manual), functionality may be severely restricted. ProCOM uses the latest version of Bluetooth Mesh which is not commonplace in the arb market, therefore we are unable to publish a list of which products may be compatible. Push to talk (PTT) button. When muted, this button allows you to talk only whilst the button is held. There are two basic forms: Ear plugs and ear defenders. Both types offer identical protection – there are no fundamental differences in noise protection, and they are both available in various designs for different purposes. They can also be combined with other personal protective equipment (PPE) components such as helmets or visors.

But not all noise is the same. In addition to the strength of the sound, the distance from the source of the noise is also important. For example, the question of whether an engine is directly next to the ear while working – as with hedge trimmers – or whether it is more than one metre away, as with lawn mowers, makes a difference. So it is important to know how much noise the ear is directly exposed to when choosing the right hearing protection. Mute/unmute button. When unmuted, you will hear your own voice through the headset as a reminder you are unmuted. Other users will hear everything said while the headset is unmuted. A. Although we recommend ProCOM for use with the ADVANCE X-Climb helmet, ProCom headsets will fit on any helmet compatible with 3M attachments.

By far the highest light transmission values. Very robust grid, honeycomb-like structure. Stainless steel material. Ear defenders are suitable for all types of work, both indoors and outdoors. They can also be used in all types of weather. In cold temperatures, this form of hearing protection also offers the advantage of keeping the ears warm as you work. As hearing protection, the Dynamic BT has some decent noise reduction, particularly at the higher frequencies and they feel durable enough to take a beating. A. The internal speakers are limited to a maximum of 82 db for all audio you will hear including music and voice communication. Given the high SNR rating of the ear defenders, you will still be able to hear all audio clearly.

Standard model heads: For these, first remove the head from the trimmer and open it up. Now you can access the empty spool you can wind trimmer line onto it. The arrows will help you to wind the line on in the right direction. If you find it difficult to refill and replace the trimmer line, your local STIHL dealer will be happy to help.

More grass trimmer tips

Ear plugs are usually made of conically shaped PU foam and can be inserted easily into the ear canal. Thanks to their deep seat within the ear, they offer good sound protection. As they are not worn on the outside of the head, earplugs are also usually more comfortable than ear defenders if you wear glasses too. Place the connecting cable for the ear defenders below the helmet insert that was initially released, so that the connecting cable is then located between the helmet shell and the helmet insert. Comfort model heads: Grass trimmer heads with comfort features are designated by the letter “C” in the model name. It is easy to replace trimmer line in these because you can wind line onto the spool from the outside. Simply feed the desired length of trimmer line into the mowing head so it goes in one side and comes out the other; then, twist the bottom part of the head to wrap the line around the spool inside – there’s no need to open anything up. One thing to note when you replace the line in these is that the two line ends which protrude from the head should be the same length before you start winding. Mount the visor on the new ADVANCE ProCOM ear defenders. Ensure that the ear defender with the microphone is on the left side. March 2022 sees the introduction of the new STIHL ADVANCE ProCOM headsets, an innovative headset for forestry professionals and landscapers that combines ear protection with intelligent communication for teams. We’ll delve into detail on the many features of ProCOM headsets here, but for in-depth instructions and guidance on how STIHL ProCOM can be used, see our other blog post here.
