The changes in the acid density must be considered when using the mobile crane
in tropical zones. Monitor the acid temperature continuously when charging.
•
Always pay attention to a good charge condition in winters. If the mobile crane is idle for a prolonged time,
the batteries need to be recharged.
•
The charging current may amount to a maximum of 1/10 of the battery capacity.
- Grease the connecting terminals slightly with acid-free and acid-resistant grease (e.g. Vaseline).
•
Electroconductive parts such as tools, etc. may not be placed on the batteries because of a danger of
short-circuiting.
•
The batteries are not charged if the battery charging pilot lamp does not turn off at higher engine speed.
Repair the cause immediately (controller or generator).
7.1.2 Installing new batteries
•
Connect the positive cable ( + ) first and then the negative cable ( - ) when installing new batteries.
•
Proceed in the reverse order when removing the battery .
7.2 Three-phase generator
The service life of the three-phase generator is determined with the storage condition. Therefore, always
ensure that correct Vee belt tension is used (see the operating manual of the engine manufacturer).
•
Get the generator checked in a specialist workshop at regular intervals. It needs to be done earlier in case
of severe dust accumulation or high ambient temperatures.
•
Operate the generator only with the controller and when the batteries are connected.
•
Ensure the correct polarity when connecting the batteries, otherwise the diodes in the generator may get
damaged.
•
Carry out the installation work on live parts only when the engine is at a standstill and the batteries are
disconnected (precautionary measure).
•
Do not dab against the earth to check whether the current is available.
•
The generator is pre-excited by the batteries and this is indicated using the charging indicator lamp. A
damaged charging indicator lamp must therefore be replaced to ensure the proper pre-excitation.
7.3 Starter
Keep in mind the instructions of the engine manufacturer.
