can mean that the battery cannot be charged.
• 
If the terminal clamps are connected to the 
battery terminals with the wrong polarity. The 
protection against swapped poles ensures 
that the battery and charger do not get da-
maged. Remove the charger from the battery 
and start the charging process from the 
beginning again. Caution! Protection against 
swapped poles is not available when the 
SUPPLY program is used.
• 
 If there is a short-circuit between the two ter-
minal clamps (the metal parts of the clamps 
come into contact with each other). The pro-
tection against short-circuits ensures that the 
battery and charger do not get damaged.
5.5 Finishing charging the battery
• 
Pull the plug out of the socket.
• 
First disconnect the black charging cable 
from the bodywork.
• 
Then release the red charging cable from the 
positive pole on the battery.
• 
Important! In case of positive earthing, first 
disconnect the red charging cable from the 
bodywork and then the black charging cable 
from the battery.
• 
Screw or push the battery stoppers back into 
position (if there are any).
Important! If the mains plug is pulled out but the 
charger cables are still connected to the battery, 
the charger will draw off  a small amount of elec-
tricity from the battery. We therefore recommend 
that you always completely remove the charger 
from the battery when not in use.
6. Overload cut-out
The charger has electronic protection against 
overloading, short-circuits and swapped poles 
when the 12V STD, 12V AGM, 12V Winter and 
12V M programs are used. One or more fi ne 
fuses are also fi tted. If the fuse suff ers a defect 
it must be replaced by a new fuse with the same 
amp value. If necessary, please contact our cus-
tomer service center.
7. Maintenance and care of the 
battery
• 
Ensure that your battery is always fitted se-
curely.
• 
A perfect connection to the cable network of 
the electrical system must be ensured at all 
times.
• 
Keep the battery clean and dry. Apply a thin 
coating of grease to the connection terminals 
using an acid-free, acid-resistant grease 
(Vaseline).
• 
Check the level of the acid in batteries that 
are not maintenance-free versions approxi-
mately every 4 weeks and top up with distilled 
water if necessary.
8. Cleaning, maintenance and 
ordering of spare parts
Danger!
Always pull out the mains power plug before star-
ting any cleaning work.
8.1 Cleaning
• 
 Keep all safety devices, air vents and the 
motor housing free of dirt and dust as far as 
possible. Wipe the equipment with a clean 
cloth or blow it with compressed air at low 
pressure.
• 
 We recommend that you clean the device 
immediately each time you have finished 
using it.
• 
 Clean the equipment regularly with a moist 
cloth and some soft soap. Do not use 
cleaning agents or solvents; these could at-
tack the plastic parts of the equipment. Ensu-
re that no water can seep into the device. The 
ingress of water into an electric tool increases 
the risk of an electric shock.
• 
 The charger should be placed in a dry room 
for storage. Any corrosion must be cleaned 
off the charging terminals.
8.2 Maintenance
There are no parts inside the equipment which 
require additional maintenance.
