GENERAL SAFETY 

This appliance is not intended for use by persons (including children) with reduced physical, sensory or 
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or 
instruction concerning use of the appliance by a person responsible for their safety. Children must be 
supervised to ensure that they do not play with the appliance. Cleaning and user maintenance must not be 
undertaken by children without supervision.  

 
Gases: 

The charging process produces flammable and explosive gases - the area in which charging takes 

place should be kept well ventilated.  Only connect and disconnect the battery leads when the mains supply 
is disconnected.  Avoid flames or sparks! Do not smoke! 
 

Cables: 

Make sure mains lead is located so that it will not be stepped on, tripped over, or otherwise subjected 

to damage. An extension cord should not be used unless absolutely necessary. Improper use of an extension 
cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure it is in good 
electrical condition.
