Introdução

Lubricating the bearings and coupling inside your stick mixer keeps the motor spinning freely, prevents overheating, and restores full speed. Follow this guide if the blade turns stiffly even after cleaning, or the motor sounds strained. The method uses only basic Torx drivers and a drop of light machine oil, and can be adapted to most fixed-shaft immersion mixers.

    • Observe if the shaft rotates stiffly, speed drops, or the mixer overheats; these are typical signs of a jammed drive.

    • A detachable blade unit can often be rinsed clean, but fixed-shaft models require internal maintenance.

    • Always unplug the mixer before any maintenance.

    • Immerse the blade end in boiling water for several hours to dissolve food debris and free the drive.

    • Wear heat-resistant gloves and keep the handle above water to protect the motor.

    • If the lower shaft can be unscrewed, remove it to expose the drive and check whether hot water freed the jam.

    • Skip to disassembly if the coupling still turns roughly after soaking.

    • Remove the two T10 security screws in the top housing.

    • Remove the front T10 screw near the speed buttons and the rear T8 screw beside the cable.

    • Keep screws organised; one may stay inside the shell until the halves separate.

    • Pull the upper housing straight off, pressing the speed buttons inward as it slides.

    • Lift the cable and small filter board clear of the shell so its weight does not tug on the lead.

    • The drive consists of a simple brushed motor coupled to the shaft.

    • Slide the motor assembly out of the plastic carrier and separate it from the drive shaft by pulling it rearward.

    • Place one tiny drop of machine oil on the rear motor bearing and move the shaft up and down to draw oil in.

    • Add another small drop to the front bearing, keeping lubricant away from the commutator.

    • A few rotations by hand should now feel noticeably smoother.

    • Apply one drop of oil to the plastic coupling and the reciprocating joint inside the lower shaft.

    • Move the coupling up and down to spread the oil until the parts glide freely.

    • Seat the motor onto its locating pins, ensuring alignment of the coupling.

    • Refit the lower shell, matching the moulded pins and screw imprints.

    • Tighten screws alternately to clamp the housing evenly and avoid distortion.

    • Reinstall the speed knob by aligning its slot with the front screw boss until it clicks.

    • Route the cable in its channel before snapping the top cover into place.

    • Plug in briefly and run at low speed; the drive should spin quietly without resistance.

    • Regular lubrication and cleaning prevent overheating and extend service life.

    • Screw positions and clip shapes may vary by model, so adjust the process to suit your mixer.

Conclusão

A single drop of oil on each bearing and joint restores smooth, quiet operation and saves the motor from unnecessary strain. Repeat the lubrication whenever the shaft begins to feel stiff, and always keep the blade end clean to minimise future jams.
