Instruction
1. If it is necessary to lower the chair which does not have devices for change of height at first make sure that at it the warranty period has expired. Then look whether the design shortening of legs provides it. So, some chairs, for example, school, instead of three or four direct legs are supplied by two L-shaped. Their alteration is impossible. The same concerns also the products having the only leg with support: having separated these parts from each other and having truncated leg, again it is difficult to connect them.
2. In case the chair has three or four direct legs, in the beginning find out on what height it is necessary to truncate each of legs. Then by means of ruler and thin indelible felt-tip pen measure this distance on each of legs, beginning from the end. At the same time do not take thickness of rubber or other soft pad into consideration. Being guided by these tags, truncate metal legs hacksaw, and wooden - saw. Cuts have to be strictly perpendicular.
3. Make sure that the chair does not rock. If this is so, define what of legs is too long, and slightly truncate it abrasive paper or file. From the cut-off parts of metal legs pull out chisel plastic pads. Then remove small facets from the shortened legs of chair, using file. Hammer the taken pads into openings of legs. If legs wooden, cut out new pads from porous rubber and beat them to legs.
4. Lower the chair intended for playing piano or grand piano, rotating seat concerning support clockwise, and lift - rotating it against hour hand. In the second case be careful not to allow separation of seat from support. If at this time on it the person sits, it can fall to floor.
5. Office chair is supplied with the pneumatic mechanism for change of height. For valve opening of pneumatic cylinder press down the lever located on it. Until it is pressed, apply pressure to seat, and it will fall. If to release seat, but to continue to hold the lever, the chair will rise. Having achieved desirable height, release the lever.
