The cordless Alpina ATR 20 Li Kit offers petrol-matching power-levels and excels in terms of performance, ergonomics and ease of use!
Its high-specification 20V lithium-ion battery – which can be used across the 20V cordless range – offers speedy charge-times, extended run-times and superior longevity. You’ll also get far less noise and vibration than you would from a petrol engine; and, of course, there are no nasty fumes and no stressful starting problems!
Hard to beat when it comes to user-comfort and manoeuvrability, the ATR 20 Li Kit weighs only 2.1kg (net) and combines a telescopically adjustable shaft with a soft-grip main handle, a fully adjustable auxiliary handle and balance-optimising battery positioning.
A fold-down guide means you’ll be able to trim safely and accurately around and between plants; while an adjustable cutter-head provides the perfect angle of attack for every situation.
Thanks to intelligent electronics, the ATR 20 Li Kit will keep on performing at full power right to the end of the battery charge.
Charger and 2Ah battery included in the package.

What kind of protective gear should I use?
Using this machine requires clothing that protects the legs and face from objects that could unexpectedly be thrown out during operation. It is always recommended to wear long trousers and a protective visor.
What kind of maintenance should I carry out?
To ensure that the machine is functioning correctly and to maximise its lifespan, we recommend regular (based on the frequency and intensity of use) cleaning of the battery housing and contacts as well as the cutting head (trimmer head and guard) – parts where a lot of dirt constantly builds up.
Remember that it is important to consult the user and maintenance manual for details of each of these tasks.
Which type of grass and shrubs can you work on?
This machine is able to tackle coarser plant conditions, from dense bushes with tall grass to shrub areas, where you can also cut the more stubborn plants and shrubs using the supplied metal blade.
How do you adjust the length of the line?
This model is fitted with a head using the Tap&Go system. This means that, while the machine is operating, you just have to press the control lever all the way to bring the head to maximum rotation and at the same time knock the head against the ground, which causes the line to feed out automatically. Its length can be adjusted simply, by cutting any excess to the length of the cutting blade located on the end of the guard.
For further information, see the instruction manual.
The line no longer feeds out from the head. What might have happened?
The line failing to feed out may be associated with two main factors. The first, and the most likely, is that the line might be all used up and should therefore be replaced with a new reel. There is also the possibility that the line within the head has accidentally become caught in its own windings, and is preventing the end from freely feeding out through the holes. In this case, simply open the head and re-spool the line correctly inside.
These causes and solutions normally cover the majority of cases, but there may be a variety of others, associated with the methods of use, the surface treated and the weather conditions.
Note that consulting the user manual, in the section relating to the cutting head, may provide useful information for identifying the nature of the problem.
