Chain / Drive; Chain Tension; Rims / Tires - Stromer ST1x Notice D'utilisation

• Open live parts should only be maintained and
cleaned at a Stromer dealer!
• Remove the battery before cleaning your
S-Pedelec. Ensure that the battery box is again
completely closed.
• Ensure that you do not touch and thus possibly
connect contacts when cleaning the battery.
You risk being hurt and the battery may suffer
damage if the contacts are live.
• Cleaning with a high-pressure cleaner may
damage the electrical system. The high pres-
sure might also push cleaning liquid into
sealed parts and thus damage them.
• Avoid damage to cables and electrical compo-
nents. When this has happened, the S-Pedelec
must be deactivated until it has been inspected
by a Stromer dealer!
Switch off the electrical system, remove the
battery and close the battery box before perform-
ing any kind of work on your S-Pedelec.

Chain / Drive

The drive chain must be regularly cleaned and
lubricated to ensure appropriate functioning (see
the "Deadlines and inspection work" section). Dirt
can be removed with the normal S-Pedelec wash.
Otherwise you can clean the chain by rubbing
it with an oily cloth. When the chain is clean, it
should be greased at the joints with suitable lubri-
cant. After being left to soak, the excess lubricant
should then be removed.

Chain tension

To ensure that the chain and gears can work safe-
ly, the chain must have a certain level of tension.
Otherwise it can come off and lead to a fall. Chain
gear systems tense the chain automatically.
Dirt and permanent strain wear the chain.
The chain should be replaced as soon as it can be
significantly lifted (approx. 5 mm) from the front
chain ring with your fingers.
Replacement of the chain is to be expected after
approx. 1500 km, depending on the load.
Chain OK
Chain worn
Many modern chains for derailleur gear systems
no longer have chain connectors. Special tools
are required to open/exchange/close them. They
should be exchanged by a Stromer dealer.
Other chains are supplied/mounted with chain
joints. In some cases, these can be opened with-
out the need for tools. These chain connectors can
also be used to repair a damaged chain on a ride,
if they have the correct width for the drive train.

Rims / Tires

Rims are subject to a great deal of strain
and are vital to your safety on the bike. They wear
during riding. Do not ride with a rim once you can
see damage. Have them checked by a Stromer
dealer and replaced, as required. Wear can weak-
en rims and lead to falls and serious accidents.
Also check the tyres of your S-Pedelec reg-
ularly. The lowest and highest authorised pres-
sures can be found on the side of the tyre. Please
adhere to them, otherwise the tyre may detach
from the rim of the wheel or burst. If differing
pressures are specified for the rim and the tyres,
the lower maximum pressure and the higher min-
imum pressure are to be taken into account.
For Stromer tyres in sizes 55-559 a pressure
of 3 bar/43.5 psi is recommended.
Tires are wear parts. You should therefore regu-
larly check the pressure, tread and condition of your
tires. Not every tire is designed for every type of use.
