GENERAL SAFETY PRECAUTIONS
Specic warnings and cautions used to indicate potential damage to people and machines are shown below.
DANGER!
Before performing any maintenance, repair, cleaning or replacement procedure disconnect the battery –
connector, remove the ignition key and engage the parking brake.
This machine must be used by properly trained operators only. Children or disabled people cannot use this –
machine.
Keep sparks, ames and smoking materials away from the batteries. During the normal operation explosive –
gases are released.
Do not wear jewels when working near electrical components. –
Do not work under the lifted machine without supporting it with safety stands. –
When working under the open hood, ensure that it cannot be closed by accident. –
Do not operate the machine near toxic, dangerous, ammable and/or explosive powders, liquids or –
vapours. This machine is not suitable for collecting dangerous powders.
When lead batteries (WET) are installed on this machine, do not tilt the machine more than 30° from its –
horizontal position to not allow the highly corrosive acid to leak out of the batteries. When the machine is to
be tilted to perform maintenance procedures, remove the batteries.
If the machine is equipped with lead (WET) batteries, battery charging produces highly explosive hydrogen –
gas. Keep the hood open when charging the batteries and perform this procedure in well-ventilated areas
and away from naked ames.
