7.3. Maintenance

Read carefully the attached instructions of use and maintenance, given by the company
manufacturing the battery.

7.4. Dangers and Preventive Measures
Dangers
The gasses developed
charging are explosive.
The electrolyte (diluted sulphuric
acid) is corrosive.
Lead and lead connections are
harmful.
Used batteries to be disposed according to legal regulations.
7.5. Operation in Winter Time or at low Temperatures
To avoid excessive cooling of the battery and the hydraulic system, the electric stacker with electric travel
shall not be unnecessarily exposed to cold areas.
The storage area should have normal temperatures not below + 15°C.
Charging of the batteries below +15°C will take longer and is not economical.

temperature of the electrolyte ° C
Batteries should be recharged daily or more often, although consumption has been less than 80% of the ca-
pacity.
The electrolyte of a battery discharged by 80% (acidity 1,13 kg/l) will already freeze at -12° C.
Heavy discharged batteries are subject to freezing at temperatures just under 0°C.
The electrolyte of a newly charged battery (acidity 1,28 kg/l) will freeze only at approx. - 68°C.
The cooling period of a newly charged battery may last up to 12 hours depending on temperatures.
Before taking the stacker into operation and in order to warm up the oil, the lifting system should be operated
in unloaded state several times prior to leaving the temperature storage area.
For permanent operation at winter temperatures we recommend the use of multigrade lubricants for the hy-
draulic system and the wheel hub gear.
Please contact our Technical Department for questions concerning application and type of lubricant.
Design changes under reserve!
Charge Battery
Control the electrolyte level. If required, refill cleaned water as per DIN
43530 (distilled water) towards the end of recharging.
Control all cells for equal gassing at the end of recharging. Check
acidity and temperature.
Check the pole terminals for tight connection.
Towards the end of the recharging control voltage
Check charging device and charge the battery.
Preventive Measures
Have charging area well ventilated. Avoid open flames and sparks.
during
Smoking prohibited.
Wear protective clothing, eye protectors and safety gloves.
When handling batteries do not eat or drink.
Wash your hands thoroughly after having worked on batteries.

At low temperatures the battery ca-
pacity is quickly reduced (reference
values see diagram), that means the
operating time is reduced with de-
scending temperatures.
