Final assembly
Your tricycle has been delivered to your spe-
cialist dealer only partly assembled.
Your dealer has carefully finished the assem-
bly, perhaps altered the specification of your
tricycle to meet your special requirements
and performed a test ride. Please make sure
that this pre-delivery service is recorded in
the Warranty Pass at the end of this manual.
All screws must be checked and tightened,
especially on the handlebar, stem, knuckles,
swing arm pivot and wheels. Please follow the
tightening torque settings listed in the table on
page 88.
Derailleurs and brakes must be checked and
adjusted. Please follow the instructions in the
manuals of the parts manufacturers that come
with this manual.
Bolts and nuts
Screws gradually settle in and hence they can
come loose. Therefore check the screws and
screws regularly if they are tightened appro-
priately with a torque wrench.
In the tables on page 88 and 89 you will find
the prescribed tightening torques, they refer
to greased screws!
Caution! Screws must be tight-
ened with prescribed tightening torque. In
this manual tightening torques are given in
"Nm“ (Newton meter). Always use a
torque wrench wherever a torque setting
is given in this manual. Never rely on "feel-
ing". Screws tightened too much or not
enough can break, which can lead to dan-
gerous accidents. In case you don't own a
torque wrench have your bicycle mechanic
do the respective work. You will find ta-
bles with the prescribed torque settings on
page 88 and 89 in this manual.
The grease also prevents your screws from
seizing in their threads so that they won't un-
screw anymore. In particular, screws made of
stainless steel are susceptible to this and
therefore have always to be put in with
grease.
Do use high quality acid free grease, if possible
a lubricant with added solid particles like Tef-
lon or MoS2. Their ingredients still work
properly after the thinner grease has been
removed from the contact surfaces.
Alternatively you can use thread locker that
you apply to the screw before you put it into
the thread.
Always check the screws very diligently for
signs of corrosion. Rust at the screw heads
may also lead to the screw seizing in the
thread. When the metallic and shiny coating
of galvanised screws comes off and discloses
dull, gray-brown steel you have to exchange
the screw.
When you exchange screws please only use
screws of the same type. Screws come in dif-
ferent strength classes. Please only use galva-
nised screws of the same type and strength,
corresponding to the German strength class
8.8 or stainless steel screws grade A2-70,
