5. Bruksanvisning
Your tectake Racing Mike Office Chair offers several adjustment options for optimal comfort.
5.1. Justering av setehøyde
Slik justerer du setehøyden:
- For å heve: While standing, pull the lever located under the right side of the seat upwards. The seat will rise automatically. Release the lever at the desired height.
- For å senke: While seated, pull the lever located under the right side of the seat upwards. The seat will lower. Release the lever at the desired height.
5.2. Justering av vippemekanismen
The chair features an infinitely adjustable tilt mechanism:
- To activate/deactivate tilt: Push the same lever (used for height adjustment) inwards to lock the chair in an upright position, or pull it outwards to allow the chair to tilt freely.
- For å justere tiltspenningen: Rotate the round knob located under the front of the seat. Turn clockwise to increase tension (making it harder to tilt) or counter-clockwise to decrease tension (making it easier to tilt).

- Maskinvaresjekk: Sjekk regelmessig alle skruer og bolter for å sikre at de er stramme. Stram til om nødvendig for å opprettholde stabilitet og sikkerhet.
- Hjulpleie: Keep the wheels free of hair, dust, and debris to ensure smooth movement.
- Unngå direkte sollys: Langvarig eksponering for direkte sollys kan forårsake falming og materialforringelse.
