Shimano ULTEGRA SL-BS78 - TECHNICAL Service Instructions

General Safety Information
WARNING
– To avoid serious injuries:
Obtain and read the service instructions carefully
prior to installing the parts. Loose, worn, or damaged
parts may cause serious injury to the rider.
We strongly recommend only using genuine
Shimano replacement parts.
Read these Technical Service Instructions carefully,
and keep them in a safe place for later reference.
NOTE:
Do not turn the ring until the lever has been secured
to the body unit.
For smooth operation, use the specified outer casing
and bottom bracket cable guide.
Because the high cable resistance of a frame with
internal cable routing would impair the SIS function,
this type of frame should not be used.
The sliding surfaces of the inner cable and outer
casing should be greased before use.
The shifting lever can be installed to handlebars with
diameters of 19.0 – 22.0 mm.
Operation of the levers related to gear shifting
should be made only when the front chainwheel is
turning.
Parts are not guaranteed against natural wear or
deterioration resulting from normal use.
For any questions regarding methods of handling or
maintenance, please contact the place of purchase.
