7.1 Dangers and Preventive Measures
Dangers
The gasses developed during charg-
ing are explosive.
The electrolyte (diluted sulphuric ac-
id) is corrosive.
Lead and lead connections are
harmful.
Used batteries to be disposed according to legal regulations.

Temperatur of the elektrolyte° C
Batteries should be recharged daily or more often, although consumption has been less than 80% of the
capacity.
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 pallet truck 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
hydraulic system and the wheel hub gear.
Please contact our Technical Department for questions concerning application and type of lubricant.
7.3

Cleaning operation

Using flammable fluids is strictly forbidden in cleaning the truck. Before cleaning work starts, safety
measures must be taken to avoid sparkling (e.g. caused by short circuit). Any operation of battery
should be performed after cutting off the power of the battery. All electric elements and electronic as-
semblies can only be cleaned by gentle wind blower, compressed air or in conductive and anti-static
brush.
If the truck is cleaned by water jet cleaner or high pressure cleaner, all electric elements and electronic
assemblies should be covered in advance to avoid humidity which will cause function fault. Noting that
cleaning by using steam nozzle is prohibited.

Maintenance and inspection works
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.
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.
To avoid excessive cooling of the battery and the hydraulic sys-
tem, the electric pallet truck with electric travel shall not be un-
necessarily 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.
At low temperatures the battery capacity is quickly reduced (ref-
10 20 30 40
erence values see diagram), that means the operating time is
reduced with descending temperatures.
