Before you take your trike on the road
Danger!
Never attempt to straighten any bends in safety-relevant
parts, like the frame, fork, handlebars, pedal crank,
saddle bar, and pedals. make sure to replace these parts
instead to brevent breakage!

3.3 Spokes

Any lose spokes must be tightened by an authorised
workshop. Torn spokes must be replaced immediately.

3.4 Brakes

3.4.1 Special safety instructions

• Brake support assembly, cables and cable sleeves
must only be replaced by an authorised technician
• Check the proper alignment and thickness of the brake
pads along the wheel rim.
• Stop driving immediately if unusual brake character-
istics occur. Contact an authorised workshop im-
mediately.
• Brake pads with asbestos content must not be used.
• New brake pads will develop their full brake potential
only after several braking actions.
Danger!
• Familiarise yourself with the effectiveness of your
brakes. Practice emergency brake manoevers, as this
may prevent accidents on the road. Develop a feel
for the ef cacy of the front wheel brake in particular.
The front wheel must not lock during braking! A
locked front wheel could cause you to fall.
• Brake pads must be replaced only with identical
model versions. Check for a brand name or logo,
and compare the type description.
3.4.2 Adjusting and loosening the brake
lever
You can secure your trike with the hand brake.
Pull the hand brake and simultaneously push the
arrester forward (Fig. 20-B). Pulling the brake lever
(Fig. 20-A) will release the arrester.

3.4.3 Adjusting the brake pads

Make sure that the brake reaction is instant (taking
into consideration the relevant brake line clearance)
when the lever is pulled. Brakes will have to be read-
justed from time to time because of the "settling" of
the brake cables and natural wear of the brake pads.
Fine tuning the cantilever brakes:
Release the counter nut (Fig. 21) and unscrew the
knurled setting screw (Fig. 21-B) until the desired
"clearance" is set. Retighten the counter nut. Should
the setting range be insuf cient, then tighten the setting
screw up to 2-3 mm and release the cable clamp on
Fig. 21
the body of the brake assembly. Press both brake pads
against the wheel rim, tension the brake cable and
retighten the cable clamp. Ensure that the brake cable
sleeve ends (Fig. 21-A) are held securely in the cable
clamps. Repeat the ne tuning of the brake with the
setting screw.
3.4.4 Brakes & brake pad adjustment
For drum brakes please read the separate
operating instructions provided.
Measurement A must not be less than 39 mm when
you press the brake shoe against the rim. Swap the
grey setting rings where necessary (6 mm and 3 mm
thickness). Use the attachment nuts to attach the
brake shoes with a torque of 6-8 Nm. The steel plates
must lie at against the brake lever (Fig. 22).
Lead the brake cable through the cable guide tube
and attach it with the cable attachment screw to the
right-hand side brake lever. Make sure that the distance
between the brake shoes and the rim is approx. 2 mm
on both sides. Tighten the screw with a torque of 6-8
Nm (Fig. 22a).
Use the spring tension adjustment screw to adjust the
distance, until it is approximately the same on both
sides (Fig. 22b). Activate the brake lever at least 8
times in a row to check its proper function and then
