The SYS95 range of seating as been designed to offer the most robust of stadium seating whilst at the same time giving the minimum of upkeep and maintenance, however the following points should be observed to maximize the longevity and trouble free operation.
a) CLEANING.
The polypropylene seats and backs should be washed down with a soft cloth or sponge using clean water or water with a small amount of domestic washing up liquid added. On no account should chemical or petrol based cleaning solvents be used as these may attack the surface of the plastic. Cleaning with a hosepipe or jet washer is acceptable but care should be taken in the area of the numbered recess in the backrest in order not to dislodge or loosen the self adhesive number.
b) MAINTENANCE.
The only moving parts of the SYS95 are the seat base pivots which will benefit from a spray of propriety oil occasionally , WD40 or such every 3 months. This should be sprayed lightly down each pivot over the pivot pin.
c) VISUAL CHECK AND INSPECTION.
The SYS95 is manufactured to a very high strength specification to withstand the use and abuse that modern stadium seats are subjected to however nothing is completely indestructible and a regular visual check will generally reveal any damage. The seat back rest is the most vulnerable part of the SYS95 and is normally subjected to the most abuse, in the event of damage the stainless steel bolts and nyloc nuts will
need to be undone using two 10mm spanners and the damaged backrest replaced. In the unlikely event that a seat base is damaged it is easier to drill out the four rivets with the seat still in place and then rivet a new seat on rather than try and remove the seat ring from the columns as the SYS95 is designed not to be easily removed by the supporters.
d) CERTIFICATION.
The SYS95 as been tested to and passed BS EN 12727:2000 Test level 4 and also BS4875; (1985) part 1 to level 5. It as also passed ignition source 0 and flame spread tests in accordance with Current regulations.
