Inspection of maintenance-free battery charge state
The charge indicator on the battery shows the state of
charge of the battery:
• If the color is green the charge is correct.
• If the color is black the charge is insufficient.
Recharge the battery until the indicator turns green.
• Transparent (colorless): replace the battery as soon
as possible.
Checking the electrolyte level of a maintenance-free battery
Remove the cell caps and check the level in each bat-
teries cell.
• The level should be between 10 mm (0.4 in) and
15 mm (0.6 in) above the plates.
• Add distilled water if necessary, then install the cell
caps.
NOTE: When adding distilled water at temperatures below
0 °C (32 °F), the batteries must be charged or the engine
run for two hours approximately in order to ensure that the
distilled water and the electrolyte are properly mixed.
NOTE: Make sure the battery terminals are clean and
coated with grease and that the cables are properly tight-
ened.
Replacement of the battery
To replace the batteries proceed as follows:
1. Set the battery disconnect switch to the OFF po-
sition. Remove the terminal protection caps, and
cut-off the negative-terminal cable. Next, cut-off
the positive-terminal cable. Remove the anti-sul-
furation pellets and the battery clips.
2. Attach a new battery, and return the clips to their
original positions.
3. Clean the cables and the battery terminals, and
apply grease.
4. Attach new anti-sulfuration pellets, and connect the
positive and the negative cable to the positive and
the negative terminal of the battery respectively.
Attach the terminal protection caps. Set the battery
disconnect switch to the ON position.
5. Attach the skid plate.
