WARNING
Do not open any of the components. Service
u
should only be carried out at an authorized
Bosch eBike dealer. Failure to follow above warn-
ing can cause death or serious injury. Refer to your
bicycle manual or component manual for all non-
Bosch drive system components.
Always remove the battery pack before per-
u
forming any bicycle inspection, maintenance or
repair. Failure to remove the battery pack before
performing bicycle inspection, maintenance or re-
pair can lead to serious injury.
If you suspect that something is loose, do not
u
ride your bike. See your Bosch eBike dealer, only a
qualified service provider should perform work on
your Bosch Drive System. All nuts, bolts, screws re-
quire the correct tightening force. Too little force
and the fastener may not hold securely. Too much
force and the fastener can strip threads, stretch,
deform or break. Either way, incorrect tightening
force can result in component failure, which can
cause you to lose control and fall.
If replacing your battery, buy only a genuine
u
Bosch battery pack from an approved source.
See your Bosch eBike dealer for original Bosch
parts.
Always switch the battery pack off, when insert-
u
ing or removing it from the holder. Never attempt
to insert or remove the battery pack while riding
the bike.
Do not charge or use your eBike in any area with
u
a potentially explosive atmosphere, such as at a
fueling area, or in areas where the air contains
chemicals or particles (such as grain, dust, or
metal powders). Obey all signs and instructions.
Do not submerge your eBike components in wa-
u
ter, or wash with pressurized hose. Your Bosch
drive unit is designed to be water tight to rain water
or non-pressure hose washing.

Taking care of your eBike
Please observe the operating and storage tempera-
tures of the eBike components. Protect the drive unit,

peratures (e.g. from intense sunlight without ade-

once a year (including mechanical parts, up-to-date-
ness of system software).
Please have your eBike serviced and repaired by an
authorized bicycle dealer.
