4. Monteringsvejledning
Assembly is straightforward and typically takes about 20 minutes. Two tools are included for your convenience. It is recommended to have assistance for attaching the armrests.
- Fastgør hjul til stjernebase: Insert each of the five casters into the holes at the end of the star base legs. Push firmly until they click into place.
- Indsæt gasløft: Placer gasløftecylinderen i det centrale hul på stjernebasen.
- Fastgør mekanismepladen til sædet: Align the mechanism plate with the screw holes on the underside of the seat cushion. Ensure the front of the mechanism plate faces the front of the seat. Secure with screws and washers using the provided Allen key.
- Attach Armrests to Seat and Backrest: Position the armrests on the sides of the seat cushion, aligning the holes. Secure the armrests to the seat using screws. Then, align the backrest with the upper holes of the armrests and the back of the seat. Secure the backrest to the armrests and seat. Note: It may require some force to align the holes correctly, especially for the backrest. Screw gradually and evenly on both sides.
- Tilslut sædeenheden til gasliften: Placer forsigtigt det samlede sæde og ryglæn på gasliftcylinderen, og sørg for, at mekanismepladens midterste hul flugter med toppen af gasliften.
Once assembled, ensure all connections are tight and the chair feels stable before use.
5. Betjeningsvejledning
Your tectake office chair offers several adjustment features to customize your seating experience for optimal comfort and ergonomic support.
5.1 Højdejustering
Sådan justeres sædehøjden:
- For at hæve: While standing, pull the lever located on the right side of the seat upwards. The seat will rise automatically. Release the lever when the desired height is reached.
- For at sænke: While seated, pull the lever located on the right side of the seat upwards. The seat will lower. Release the lever when the desired height is reached.
5.2 Tilt Mechanism and Tension Adjustment
The chair features a continuous tilt mechanism that allows the backrest and seat to recline together. The tension of this tilt can be adjusted to suit your weight and preference.
- Sådan aktiverer/deaktiverer du vipning: Pull the same lever used for height adjustment outwards to enable the tilt function. Push it inwards to lock the chair in an upright position.
- Sådan justeres hældningsspændingen: Rotate the round knob located underneath the front of the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
5.3 Ergonomisk støtte
The chair's design, including the padded backrest and headrest, provides ergonomic support to promote a healthy posture and reduce fatigue during extended use.

6. Vedligeholdelse og pleje
Proper care will extend the life and appearance of your tectake office chair.
- Rensning: The synthetic leather material should be dry cleaned. For minor spills, wipe immediately with a soft, damp en klud og en mild sæbe, og tør derefter grundigt. Undgå skrappe kemikalier eller slibende rengøringsmidler.
- Regelmæssig inspektion: Kontrollér regelmæssigt alle skruer og bolte for at sikre, at de forbliver stramme. Spænd dem igen om nødvendigt.
- Smøring: If the tilt mechanism or casters begin to squeak, a small amount of silicone-based lubricant can be applied to the moving parts.
- Undgå direkte sollys: Prolonged exposure to direct sunlight can cause the synthetic leather to fade or crack.
7. Fejlfinding
Here are solutions to common issues you might encounter with your office chair:
| Problem | Mulig årsag | Løsning |

| Stolen justerer ikke højden | Gas lift cylinder is faulty or lever is not engaged correctly. | Ensure the lever is fully pulled up. If the issue persists, the gas lift may need replacement. Contact support. |
| Stolen vakler eller er ustabil | Løse skruer eller ujævnt gulv. | Check and tighten all assembly screws, especially those connecting the armrests and mechanism plate. Ensure the chair is on a flat surface. |
| Squeaking noise during movement | Friction in moving parts (e.g., tilt mechanism, casters). | Apply a small amount of silicone-based lubricant to the pivot points of the tilt mechanism and caster stems. |
| Hjulene ruller ikke jævnt | Affald sidder fast i hjul eller slidte hjul. | Clean any hair or debris from the caster wheels. If casters are worn, they may need replacement. |
