• Driving shaft into gears
The motor shaft must be pressed into gears. To reduce
the sock and protect the gears and cranks, using a lever
is recommended. However, if one is not available, tap the
gears and cranks gently so as not to damage them.
Please pay careful attention to the procedure.
The flat side
• Parts made of Rubber
Parts made of rubber will stretch. Be careful not to stretch
them too much or they will break.
Use a diagonal cutter to detach the parts.
• Tightening the lock nut
Lock nut is a special kind of nut, which has a nylon ring
inside in order to prevent the nut from becoming loose
while the assembled kit is operating. When screwing in-
to a lock nut, its direction is important : it needs to be
screwed from the flat side of the nut. When screwing in-
to a lock nut, more power is needed compared to a reg-
ular nut. Use a screwdriver with a bigger handle, so that
the power for turning the screw is used more efficiently.
Use long-nose pliers or a nut driver to hold the nut, when
screwing.
• Tightening of nuts and screws
Tighten nuts and screws properly, or they may come
loose. Overtightening may also cause damage. Tight-
en them just enough to work properly.
