Problem: When reclining, the chair makes a squeaking noise
1. First, determine which function is making the squeaking noise by testing each of the recline motors with the
corresponding UP / DOWN buttons: FOOtrESt, BaCKrESt and rOtatE.
2. Once you have determined which motor makes the squeaking noise, lubricate the point where the motor moves
in and out of its housing, underneath the chair (with WD-40 or 3-iN-ONE oil). if the chair still squeaks, continue with
step 3.
3. Use WD-40 or 3-iN-ONE oil to lubricate the side bolts that connect the backrest with the seat frame of the chair.
these bolts are located between the backrest and the armrests on each side of the chair.
