SAFETY
• The Spectro hubs are equipped
with permanent lubrication and
are maintenance-free under
normal conditions. For type
MH 3115, however, particularly
high loading of the coaster
brake can cause it to over
compensate. In this case, apply
special grease to the brake
sleeve. Lubrication should be
done by a professional only.
• Occasionally oil the control
cable and the small chain.
• Do not clean gear hubs using
water under pressure (Fig. 7.)
(e.g. sharp water jet, high pres-
sure cleaner etc.) – water in the
system can cause it to malfunc-
tion.
• Should the rear wheel develop
too much side play, have it
readjusted by a professional.

Improved braking in third gear.
Feature:
when braking in third gear, the

Deflection pulley by approx. one
chain link – after braking, the indi-
cator chain returns immediately to
its normal position.
