5. Arahan Operasi
Your Yaheetech Ergonomic Office Chair offers several adjustable features to customize your seating experience:
5.1 Pelarasan Ketinggian Tempat Duduk
To adjust the seat height, pull the lever located on the right side under the seat upwards. While holding the lever, stand up to raise the seat or sit down to lower it. Release the lever at your desired height to lock it in place.

5.2 Recline/Rocking Function
To enable the rocking function, pull the same lever (used for height adjustment) outwards. To lock the chair in an upright position, push the lever inwards. The tension of the rocking motion can be adjusted by rotating the round knob located under the seat, towards the front. Turn clockwise to increase tension (harder to recline) and counter-clockwise to decrease tension (easier to recline).

5.3 Armrest Adjustment (Foldable)
The armrests can be folded upwards by 90 degrees. Simply lift the armrests to raise them. This feature allows the chair to be pushed closer to your desk, saving space when not in use.
