the battery yourself:

Always replace a faulty battery with a battery

which meets the specic vehicle require-

ments.

elbow ttings or terminal covers from the bat-

tery which is to be replaced.

Make sure that the vent hose is always con-

nected to the original opening on the side of

the battery.

Fit any existing or supplied cell caps.

escape.

Make sure that detachable parts are recon-

nected in the same way.
