Adjustment of height of seat and handlebars

The height of seat and handlebars may be
adjusted by the driver as required. The inclination
of seat is adjusted after loosening of nut A (fig.12).
The tightening of nut A is to be checked from time
to time to avoid the tear of holder teeth. The height
of seat is adjusted after loosening of nut B. This is
able to be adjusted in the limits of 120 mm. The
height of handlebars may be adjusted after
loosening of screw A 

and both nuts B

 (fig.13)

within the limits of 100 mm. After adjustment of
seat and handlebars the nuts and the screws are
to be tightened thoroughly.

Adjustment of brakes

For the current adjustment of front and rear brakes
are used the screws arranged on the handlebars
(fig.14). When adjustment loosen the knurled nut
(1) and by screwing in or out the screw (2) is taken
up the clearance of brake lever so that after the
compression the lever is distant from the handle 20
to 30 mm. After adjustment of brake the nut (1) is
to be tightened.
If the brakes are not able to be tightened by the
screws arranged on the handlebars these may be
adjusted on the brake cams, (fig.15 and fig.16) by
tightening the brake cable. Then the final
regulation of brake adjustment is to be effected by
the screws arranged on the handlebars.
Check after adjustment of brakes whether these
are not tightened too much. Put the moped onto
the stand and ascertain by rotating the wheels
whether these rotate freely without the jerks.
