Product detailed description

MAFELL | LS 103 Ec – řetězová dlabačka pro tesařské spoje

A mortise in a beam in a single pass

The MAFELL LS 103 Ec chain mortiser cuts a deep mortise in a single pass. This eliminates the need for drilling and manual finishing with a chisel.

Depending on the chain set used, you can create a mortise 30, 35, or 40 mm wide and 100 or 150 mm deep.

2,500 W for jobs where a standard router isn't enough

The LS 103 Ec is powered by a high-performance CUprex motor with a power input of 2,500 W. The purpose of this power isn’t to chase numbers on a spec sheet, but to drive the chain smoothly into a solid beam and create a deep mortise without unnecessarily slow material removal.

It is precisely when producing a large number of carpentry joints that the difference compared to drilling a hole and then finishing it by hand is greatest.

8.7 kg—so it’s actually practical to use on a construction site

For a machine designed for large beams, power isn’t the only important factor. The LS 103 Ec weighs 8.7 kg without the power cord, so it can be carried between individual joints and used even on structures where handling a heavier machine would be significantly more cumbersome.

The ergonomic layout of the handles and controls is designed to ensure the user maintains control of the machine during mortising.

Large beams are no problem

A long crosscut fence with a wide adjustment range allows the mortiser to be set up even for large structural lumber. The machine is therefore not limited to smaller workshop blanks and is particularly useful for the production of timber structures, pergolas, roof trusses, and other carpentry projects.

The LS 103 Ec can also be used in a horizontal position, allowing it to adapt to the orientation of the workpiece and eliminating the need to struggle with heavy beams.

Replacing and Tensioning the Chain Without Unnecessary Disassembly

The clamping system is designed for quick replacement of the cutting chain. In addition, the chain can be tensioned even with the protective guard installed, which saves time during operation and facilitates routine machine maintenance.

Contents of the Package

Depending on the selected model:

  • MAFELL LS 103 Ec chain groover
  • Corresponding guide rail
  • Corresponding cutting chain
  • chain sprocket
  • cross stop
  • 4 mm hex key
  • 8 mm hex key
  • 10 m power cord
  • Operating Instructions and Safety Guidelines

The complete set therefore also includes a chain set corresponding to the specific model ordered.

Which LS 103 Ec model should I choose?

Two values are particularly important: the desired slot width (30, 35, or 40 mm ) and the desired depth (100 or 150 mm). Select the appropriate chain set based on these values.

Is the FG 150 guide base required for the 150mm version?

Yes. MAFELL lists the FG 150 as an essential accessory for working with 150mm chain sets.

Is the cutting chain included in the package?

Yes. The complete sets listed here include the corresponding guide bar, cutting chain, and sprocket.

What type of material is the LS 103 Ec designed for?

According to the MAFELL operating instructions, the chain mortiser is designed for mortising solid wood using approved chain sets.

Is the LS 103 Ec also suitable for use directly on a construction site?

Yes, this is where its combination of high power and relatively low weight—8.7 kg—really shines. In addition, the long crosscut fence allows you to work on large beams.
