Troubleshooting
If something doesn’t work…
Malfunctions are often caused by minor faults. You
can easily remedy most of these yourself. Check
against the following table first before contacting Ser-
vice. You will save yourself a lot of trouble and possi-
bly money too.
DANGER! Risk of injury! Switch off all
consumers in the vehicle and the ignition of
the vehicle to be started.
DANGER! Risk of injury!
Avoid contact
with moving and hot engine components.
DANGER! Risk of injury! Always pay
attention to the correct polarity and firm
seating of the battery terminals when con-
necting the device to a battery, and avoid a
short circuit by touching the battery termi-
nals.
NOTICE! Product damage! In case of
maintenance-free batteries, the charging
process must be immediately discontinued
when the indicator of the charging state dis-
play is on "full". Maintenance-free batteries
are closed. If the charging process is not
stopped, the overpressure valve of the
maintenance-free battery opens during "out-
gassing“. A fluid deficit arises, as it no longer
closes. The capacity is reduced during each
operation, and the battery is destroyed.
NOTICE! Product damage! The charging
cables must not be extended under any cir-
cumstances!
NOTICE! Product damage! Disconnect
the battery from the vehicle. This prevents
damage to the three-phase generator. To
prevent damage to the vehicle bodywork,
remove the battery completely.
Note: Use sufficiently strong metal parts of
the frame to earth the black minus terminal
to ground.
NOTICE! Product damage!
Stop the
charging process:
• If no progress can be detected on the
charge status indicator over a longer
period of time. The battery may then be
defective.
• If you detect intense heat generation or
gas formation.
NOTICE! Product damage! Water must
not penetrate the inside of the product.
DANGER! Risk of explosion! Avoid
intense heating of the device, (e.g. due to
exposure to sun radiation in the car or vehi-
cle heating).
DANGER! Danger to life and limb!
Improper repairs can result in the product
functioning unsafely. This endangers your-
self and your environment.
Fault/malfunction Possible cause Remedy
The device is not charging. Charging cable mixed up? Disconnect and switch off the charger.
Then re-connect and the charger and the
terminals.
