1. Problem : Armrest Play
Corrective Action :
(a) Check for the tightness of the Hex Socket head screw. Tighten the Arm rest assemblies using 5mm allen key at least once a week to avoid armrest loosening.
(b) Replace the Nylon washers if found worn out. The average life of the nylon washer is one year.
2. Problem : Backrest Play
Corrective Action :
(a) Check for the tightness of the M10 Nyloc nut once in a month. If so, tighten the M10 Nyloc nuts (4 nos) of the backrest assemblies using 16/17 spanner to avoid backrest play.
(b) Adjust the gas spring mechanism by tightening the rear nut of the mechanism using 27 DE spanner to arrest the back rest play. Ensure that adequate gap is maintained between the gas spring eye and the reclining lever. Excess tightening may result in reclining lever getting struck which in turn may lead to auto reclining of the back rest.
3. Problem : Pushback not functioning / Auto reclining
Corrective Action :
(a) Check for proper functioning of the gas spring. If any oil leakage noticed, replace the gas spring immediately
(b) Check for the tightness of the mechanism. Adjust the gas spring mechanism by tightening the rear nut provided in the mechanism using the 27 DE Spanner. Ensure that adequate gap is maintained between the gas spring eye and the reclining lever. Excess tightening may result in reclining lever getting stuck which in turn may lead to auto reclining of the back rest.
4. Problem : Upholstery fading and dust getting accumulated
Corrective Action :
(a) Vacuum clean the upholstery once in a week to avoid dust getting accumulated on to the fabric. Regular vacuum cleaning avoids fabric fading and increases the life of the fabric.
(b) Dont not use any chemical based solution to clean the fabric as it may affect the quality of the fabric.
(c) Do not use water directly to clean the fabric as water may seep in to the foams and detoriate the quality of the foam which may result in foam getting harder over a period of time.
5. Problem : Leg rest mechanism not functioning
Corrective Action :
(a) Grease the sliding bracket of the mechanism at least once in a month to ensure smooth operation of the mechanism.
(b) Check for the condition of the lever mounting bolt atleast once in three months. If found worn out, replace the same immediately.
