Battery Installation (battery) 

Two different types of battery may be installed: 

Leak proof battery: the electrolyte level must be checked regularly. When necessary, please fill up with distilled water 
until the plates are covered. 

Gel battery: this type of battery is maintenance free. The type of battery used must correspond to machine’s technical 
specifications. The use of heavier batteries could seriously jeopardise machine’s manoeuvrability and lead to motor 
brush overheating. While the use of batteries with lower capacity and weight requires more frequent charge. 

CAUTION 

To protect and extend batteries life, the machine cannot be used continuously when the power is used up. 

5.5.1.

Batteries - Preparation 

DANGER 

The operator must be provided with the necessary protection devices to limit the risk of accident when installing the 
batteries or doing maintenance. Keep away from naked flames, sparks, smokes and avoid short-circuit.  

The batteries are normally filled with acid and ready for use. If the batteries are dry, it should be proceeded before 
mounting. Remove the cap and fill every element with specific sulphuric acid solution until the plates are entirely 
covered. 

Leave for 4 or 5 hours to allow the plates to absorb the electrolyte. Make sure the level of electrolyte is still above the 
plates or fill up with sulphuric acid solution. Close the caps. Mount the batteries on the machine  

Before using the machine for the first time, please charge the batteries, following instructions.
