BATTERY FITTING


Ø  Before fitting the battery
Ø     Open (-) ve terminal first and  then (+) ve terminals
Ø  Wash terminals & posts with hot water to eliminate deposited oxides ( if  any )
Ø  Use puller wrench at the time of opening terminal from posts. Use spanner for nut & bolt.
Ø  Clean battery tray & clamp by cleaner.


BATTERY FITTING


Ø  Check all the connection properly & tightened as required.
Ø  Check the size to the terminals & replace by appropriate sizes if  necessary.
Ø  Install new battery with appropriate size.
Ø  Fix positive terminals to positive post first & check.
Ø  Use petroleum jelly & cover the post & terminal by plastic cover.
Ø  Don’t cover the battery with rubber sheet to avoid bursting.
