Equipment Safety 

 

Locate  the charger  as far  away  from  the battery  as the charger  cables allow. 

 

Do  NOT  charge  a frozen  battery. If  battery  fluid  (electrolyte)  is frozen,  place  the battery  in a warm  area  to 
thaw  before  charging. 

 

Do  NOT  allow  battery acid to contact the charger  or  any of  its components. 

 

Do  NOT  place a battery  on top  of the  charger. 

 

Do  NOT  place the charger  directly above  a  battery being  charged.  Gases from  the battery may corrode 
and  damage  the charger. 

 

Do  NOT  allow  the battery terminal  clamps to touch  at any time when  the  charger  is energized. 

 

Do  NOT  start a vehicle  engine  with  the charger  connected  to the vehicle  battery. 

 

Boat batteries  should  be  removed  from  the boat and  charged  on  land.  

 

Always select the correct voltage  of  the battery  being  charged.  Do  NOT  charger  a battery  using a 
different  voltage  to the  battery rating. 

 

Always follow  battery manufacturer  instructions for  battery charging.  

 

Always follow  vehicle  manufacturer  instructions for  in-vehicle  battery charging  or  jump-starting. 

 

When  using the equipment,  basic safety precautions  detailed  here  must always  be followed  to reduce 
the risk of  fire, electric shock, personal  injury and  material  damage.  

 

To  provide  a good  electrical  connection,  ensure  that the battery  terminals  and battery  charging  clamps 
are  clean  before  connecting  them. 

 

Ensure  the electrical  supply conforms  to the equipment  requirements. 

 

To  reduce  risk of  electric shock, disconnect  the equipment  from  the  electrical supply before  connecting 
batteries,  cleaning  etc. 

 

Do  not use an  extension  cord unless  necessary. Use of  an  improper  extension  cord could  result in fire  or 
electric shock. If  an  extension  cord must be  used, make sure  that:  

 

The  extension  cord socket is compatible  with the  charger  plug.  

 

The  extension  cord is properly  wired  and  in good  condition.  

 

The  extension  cord wire  gauge  is suitable  for  the  charger  current  rating.
