Stihl KMA 80 R Cordless Kombi Motor (AK System)

It is powered by a 36V battery from the STIHL AK System and combines a brushless EC motor with two selectable power levels and variable speed control. It is particularly well suited to home gardens, noise-sensitive residential areas and customers who already own compatible STIHL AK batteries.

Important: this listing is for the KMA 80 R power unit only. The battery, charger and KombiTool attachment are sold separately.  A basic harness is included.

The KMA 80 R is compatible with STIHL KombiTools except the FSB-KM brushcutter attachment.

Why choose the STIHL KMA 80 R?

• One motor for multiple garden jobs:
  quickly change between compatible trimming, pruning, cutting, blowing, edging, cultivating and sweeping attachments.
• Part of the 36V STIHL AK System:
  share compatible AK batteries with other domestic STIHL cordless garden tools.
• Two power levels:
  use ECO mode for lighter work and extended battery life, or full-power mode for more demanding attachments and tasks.
• Variable speed control:
  regulate the operating speed from the control handle to suit the attachment and working conditions.
• Brushless EC motor:
  efficient, low-maintenance power without petrol, pull-cord starting or engine fuel mixing.
• Low-noise operation:
  suitable for use around homes and in other noise-sensitive locations.
• Adjustable loop handle:
  provides good manoeuvrability around trees, borders, slopes and confined areas.
• Quick-release coupling:
  change compatible KombiTools without needing separate tools.
• Detachable shaft:
  separates for easier transport and more compact storage.
• No exhaust emissions during use:
  a cleaner and more convenient alternative to a petrol KombiEngine for domestic work.

STIHL KMA 80 R battery working times

Working time varies significantly according to the battery, attachment, selected power level, cutting conditions and operating technique. The figures below show approximate STIHL working-time ranges from full-power mode to ECO mode.

STIHL KMA 80 R frequently asked questions

Does the STIHL KMA 80 R include a battery and charger?

No. This listing is for the KMA 80 R power unit only. A compatible STIHL AK battery, charger and KombiTool attachment must be purchased separately. A basic harness is included.

Which batteries fit the STIHL KMA 80 R?

The KMA 80 R accepts STIHL AK 10, AK 20 and AK 30 S batteries. The AK 30 S provides the longest available working times, while a smaller battery may reduce overall machine weight for shorter or less demanding jobs.

Does the KMA 80 R work with every STIHL KombiTool?

It works with STIHL KombiTools except the FSB-KM attachment. Always check compatibility before purchasing an attachment.

How much does the STIHL KMA 80 R weigh?

The power unit weighs 3.4 kg without a battery or KombiTool. With an AK 30 S battery fitted, it weighs approximately 4.7 kg before an attachment is installed.

How long does the KMA 80 R battery last?

Runtime depends on the battery, attachment and power level. With an AK 30 S, approximate working times range from 15–25 minutes with the BG-KM blower to 90–130 minutes with an HL-KM hedge-trimmer attachment.

Is the KMA 80 R suitable for professional use?

The KMA 80 R is primarily designed for home gardens. It can handle regular and demanding domestic maintenance, but the AP System KMA 120 R or KMA 135 R is more appropriate for prolonged professional use.

Is the KMA 80 R quieter than a petrol KombiEngine?

Yes. Its battery-powered motor has lower noise emissions than a petrol engine and produces no exhaust emissions during operation, making it well suited to residential and other noise-sensitive areas.

Can the KMA 80 R be separated for storage?

Yes. The shaft can be detached without tools, making the unit easier to transport and store in a smaller space.
