1. Remove the body pad and head pillow from the chair (for more information, see Use & Care manual).

2. Fully recline the chair. NOTE: If you cannot recline the chair using the recline lever, tip the chair gently on its

side, then while using a flat-head screwdriver to push the brake tab toward the brake cable, manually move the

chair to the fully reclined position. (Fig.10).

3. Using a 5/16” Allen wrench, remove the three Allen bolts located on the left-hand inner side panel (Fig.1).

4. Using a 5/16” Allen wrench, remove the four Allen bolts located on the underside of the left-hand armrest,

which secure the armrest to the mounting plate (Fig.2).

5. Lift the left-hand armrest up to expose two bolts beneath it, then use a 5/16” Allen wrench to remove the

two bolts, freeing the mounting plate from the chair. Turn the armrest upside down (Fig. 4).

6. Using your fingers, fold back the armrest upholstery on the underside of the armrest at the rear of the

mounting plate to expose the cable end (Fig.5).

7. Locate the clamp on the underside of the armrest that secures the cable end, then use a wire cutter to split

open the clamp, freeing the cable end. CAUTION: Be careful not to damage the cable (Fig.5).
