Battery fluid level checks are unnecessary o n M F
(Maintenance Free) batteries.
Open type batteries should be checked for fluid level.

contact with the skin. eyes or clothes as
it
will cause
burning. If acid is spilled on you, be sure to wash off
quickly with large amounts of water. If battery fluid
enters the eyes, wash with water and consult a
physician.
Check for cracks in the battery case.
If the battery's electrodes show accumulation of a white
substance (sulphation) or heavy deposits are observed at the
base of the battery, the battery should be replaced.
Check the level of each cell by the UPPER and LOWER level
lines inscribed on the side of the battery.
If levels are approaching the LOWER level line, remove the bat-
tery, take off the filler caps and refill to the UPPER level with
distilled water.
Check the battery capacity with a battery tester (page 22-1 1 ) .
If the battery tester is not available, check the gravity of the
battery fluid (see below).
CAUTION
/
.
Always refill batteries with distilled water. Tap water

contains minerals that will shorten the life of the battery.
Filling the battery above the UPPER level mark may
cause spillage while riding and subsequent corrosion of
vehicle parts.
After refilling, replace each of the filler caps firmly and re-
install the battery.
Follow the instructions on the battery's CAUTION label. Make
sure that the breather tube is correctly positioned, and not
kinked, trapped or bent in such a way as to obstruct the
passage of air.
CAUTION
-
If the tube is blocked, the battery's internal pressure will
not be relieved. the breather may come off, or the bat-
tery could crack as a result.
