the battery.
Position yourself and the free end of the cable you previously attached to the NEGATIVE 

7.4 

(NEG, N, -) battery post as far away from the battery as possible – then connect the 

NEGATIVE (BLACK) charger clip to the free end of the cable.
Do not face the battery when making the final connection.

RISK OF ELECTRIC ShOCK OR FIRE.

This battery charger is for use on a nominal 120-volt circuit and 

8.1 

has a grounded plug that looks like the plug illustrated. The 

charger must be grounded to reduce the risk of electric shock. 

The plug must be plugged into an outlet that is properly installed 

and grounded in accordance with all local codes and ordinances. 

The plug pins must fit the receptacle (outlet). Do not use with an 

ungrounded system.

8.2 

 Never alter the AC cord or plug provided – if it does not fit the outlet, 

have a proper grounded outlet installed by a qualified electrician. An improper 

connection can result in a risk of an electric shock or electrocution.  

NOTE

: Pursuant to Canadian Regulations, use of an adapter plug is not allowed in 

Canada. Use of an adapter plug in the United States is not recommended and should 

not be used.
