Question 5

How to troubleshoot a HUSQVARNA S 138C scarifier that won't start?

Accepted Answer

The Husqvarna S 138C scarifier is an electric model that operates on mains power. If your device does not start, here are the troubleshooting steps to follow.

Essential checks before starting: First, ensure that the power cable is properly plugged into the socket located under the handle. Then check that the cable is placed in the designated cord holder. It is important that the anti-start (the start inhibitor) is fully released before any attempt to start. Finally, make sure to stay behind the product when starting.

Common problems and solutions: If the scarifier still does not start after these checks, begin by checking the power supply. Test that the socket is functioning properly by plugging in another device. Also check for any visible damage to the power cable or its plug. If the cable has defects, cuts, or deformations, it must be replaced immediately to avoid safety risks.

Checking safety controls: The S 138C has a strict safety system. Check that the engine brake handle is correctly positioned by gently pushing it towards the handlebars. The anti-start must be released before pressing the brake handle. If these controls are not in the correct position, the engine cannot start for safety reasons.

Blocking issues: If you hear the engine trying to start but it cannot, the problem may be due to a mechanical blockage. The rotor with its 16 blades may be stuck or blocked by debris or an excessive load of material. Immediately disconnect the power cable, wait at least 5 seconds, then visually inspect that the scarification rotor moves freely. Clear any debris or residues that may be blocking it.

Motor overload: If the device regularly stops or refuses to start after intensive use, the motor may be experiencing thermal overload. Stop the scarifier and wait for it to cool completely before restarting (at least 15 to 20 minutes). During the next use, reduce the scarification depth to decrease the load on the motor. Excessive depth can cause safety shutdowns.

Request for professional intervention: If after all these checks the product still does not start, or if it starts but stops quickly repeatedly, contact an authorized Husqvarna service workshop. Internal defects in the motor or electrical system may be the cause and require professional technical expertise.

Question 8

How to use twin needles on the Husqvarna 5710 sewing machine?

Accepted Answer

The Husqvarna 5710 sewing machine allows the use of twin needles to create decorative parallel stitches or raised effects. Here’s how to proceed:

Compatible twin needles

Three options available, all in size 80:
4114 235-01: 2 mm spacing
4114 235-02: 3 mm spacing
4114 235-03: 4 mm spacing

Mounting and usage instructions

Insert the twin needle by pushing it all the way into the needle clamp.
Use the special presser foot for raised stitches (reference 41 11 389-01).
Thread the needles one at a time to prevent the threads from tangling.
Place a thimble on each spool holder.
Pass the threads on each side of the central tension disc, then thread each needle normally.
Set the machine to straight stitch (zigzag stitch is only possible on small or medium settings).
Adjust the thread tension to modify the height of the stitch: a higher tension creates a more raised stitch.

Tip for regular parallel stitches

Use the grooves located under the presser foot as a guide to position the previous stitch and achieve uniform spacing between parallel stitches.
