L. SEATING AND SEAT SLING UPHOLSTERY
1. Seat Sling Upholstery
a.
Check monthly for excessive stretching of the upholstery, or loose attaching hardware. If you
determine the upholstery can no longer be adjusted tight, contact your Sunrise Medical
Authorized Dealer for a replacement.
2. Cushion Attachment
a.
Place cushion on the seat sling with loop material side down. The beveled edge of the cushion
should be facing toward the front of your chair. Cushion will fold over the front of the seat sling
and attach to the Velcro
®
underneath the seat sling. (Fig. 8.13)
b.
Press fi rmly into place.
WARNING
Loose or worn seat slings may sag to a point that they contact chair components positioned under the
seating surface. Using the chair in this condition may lead to pressure related injuries.
M. ADJUSTING RECLINE ANGLE (Back to Seat angle)
1.
Pull both latch handles halfway up until they contact the recline stop tab as shown in Fig 8.14. While
holding the latch handles in this position, pull or push the backrest to your desired back-to-seat angle.
2.
Check the recline angle marking on the side of the seat frame to ensure you are at the desired angle.
Possible back-to-seat angles are 85°, 90,° 95,° and 100°. (Fig 8.15)
3.
Confi rm that recline angle is positioned at the same setting on both sides of the chair.
WARNING
Ensure both recline latch pins are fully engaged. If not fully engaged, lightly rock backrest back and forth until
fully engaged. (Fig 8.16)
WARNING
Do not attempt to recline the backrest with the latch handle in the folding position, as you may
inadvertently unlock the frame. If this happens and the frame is not returned to the lock position,
completely fold and unfold the frame to return it to the lock position. Always check that the tilt link front
pivot is in the lock position as indicated on the seat frame prior to use. (Fig 8.15)
