7.2  STM 821/861

 WARNING

Danger of explosion from sparking!

When connecting and disconnecting the battery, make sure that the battery 

charger is not charging: "<-Start" is shown in the bottom row of the display.
Make sure that the battery to be charged complies with the battery charger's 

specifications.

 NOTE

The power cable and the connection cables to the battery must not be subjected 

to tension, be kinked, or laid over sharp edges under any circumstances.

Switch on the device with the mains switch (STM 861 only).
Check whether the settings displayed in the start screen match the battery 

to be charged.
If not, correct the settings as described in section 5..
Make sure that no charging process has yet started:

"<-Start" is shown in the bottom row of the display.

Otherwise, stop the charging process with <. 
Connect the charging clips to the battery:

Red: + pole, black: – pole

Stop the charging process with the < button.

The charging voltage, charging current, and battery capacity are dis-

played continually.
Once 90% capacity has been reached, "Recharge" is displayed.
Once 100% capacity has been reached, "Trickle charge" is displayed.

Trickle charging can continue for any length of time.

Stop the charging process with the < (stop) button.
Disconnect the charging clips from the battery.
Switch off the device with the mains switch (STM 861 only).

8  Care, maintenance and service

The device is maintenance-free. If functional faults occur, please consult your 

dealer and present the payment receipt/invoice.

8.1  Cleaning

Pull the mains plug before cleaning.
Regularly clean the outside of the casing with a damp cloth. Do not use 

solvents.
Ensure that the ventilation slots at the rear of the device are not obstructed 

and that the air can circulate freely. If necessary, remove dust by vacuum-

ing.

8.2  Maintenance and repair

Under normal operating conditions, the device's care and maintenance require-

ments are minimal. However, some points must be observed in order to ensure 

that the device remains operational for many years. 

Check the mains plug, mains cable, charging cables, and charging termi-

nals for damage before each use.

Repair work and servicing may only be performed by an authorised specialist. 

Only use original replacement parts and wearing parts (this also applies to stand-

ard parts). It cannot be guaranteed that third-party components are constructed 

and produced in accordance with operational demands and safety requirements. 
Do not modify or convert the device, or install any components in the device, 

without approval from the manufacturer.
