Gear shifters
14.1
The 805fe has 16 gears, comprising 2 front chainwheels
(32 and 50 teeth) and 8 rear sprockets (11 to 30 teeth). The front shifter will
move the chain between the high gear chainwheel H and the low L (please refer
to the picture). The rear shifter will move the chain from the highest gear to the
lowest by simply moving the lever from left to right.
IMPORTANT Make sure your handle bar grips are always intact and in good condition.
Uncovered handlebar tubes can be very dangerous.

then take the spacers and washers out
14.3.2. Install new brake pads, then with both
pads pressed against the wheel rim,
ensure that distance B (in the diagram)
does not exceed 65mm. To decrease
distance B, exchange wide & narrow
spacers on each brake pad. Before finally
tightening brake pads, make sure they are aligned correctly on the rim,
and there is a gap of 1mm between the top of the rim and the top of the
pad. Hold each pad against the rim (one at a time) & tighten bolt C.
Finally tighten to 6-8N.M
14.3.3. Insert cable under bolt A, slot cable guide pipe into holder and fit
protector over the guide pipe end. Set cable in bolt A so that combined
pad/rim clearance (the gaps from left pad to left rim surface and from
right pad to right rim surface) is 2mm, then tighten "A" bolt. Finally
tighten to 6-8N.M.
