BATTERY INSTALLATION AND SERVICE INSTRUCTIONS
CAUTION
Batteries must not be filled or "topped up" whilst in normal
operating position - always remove from machine.
TO REMOVE BATTERIES
1. Remove the lower rear panel (radiator end.)
2. Disconnect the battery leads. Always disconnect the
negative lead first.
3. Undo clamps and lift clear of machine.
COMMISSIONING AND RECHARGING
1. Always remove the battery from the machine before filling
or recharging.
2. Remove and retain vent plugs.
3. Fill each cell of the battery to the top of the separators with
the correct grade electrolyte* (ie. 1.260 specific gravity).
Using higher or lower specific gravity electrolyte than
recommended can impair the battery performance.
4. Boost charge the battery at 15 amps until the specific
gravity of the electrolyte is 1.250 or higher and the
electrolyte temperature
CONDITIONS MUST BE MET. If electrolyte bubbles
violently while charging, reduce the charging rate until the
excessive bubbling action subsides, then continue until
both of the above conditions are achieved.
If the ambient temperature is 10ºC or less, it is imperative
that the above instructions be followed.
5. After boost charge check level of electrolyte in all cells. Add
additional electrolyte to bring level to that shown on
labelling. DO NOT OVERFILL. After the battery has been
in service, add only approved water. DO NOT ADD ACID.
Note: Depending on the age of the dry charged battery
correct activation may take up to 48 hours.
6. Disconnect the battery from the charging source and refit
the vent plugs ensuring they are screwed or pushed all the
way home.
7. Wash away any split electrolyte with water and dry the
battery completely before installing it into the machine.

INSTALLATION
1. Inspect the battery tray and remove any foreign objects that
may be present.
2. Place the battery in the tray.
3. Connect the positive battery lead (marked with a red band),
then connect the negative lead.
Note: Always connect the negative lead last when installing
a battery.
4. Refit the battery hold-down assembly. Do not over tighten
this assembly as battery case damage is possible.
Note: To prevent acid surge from bottle when filling,
carefully pierce a small hole in the top of the acid bottle to
WARNING
allow bottle to breath.
• Battery electrolyte contains sulphuric acid which is
corrosive to skin and clothing.
• Batteries also contain explosive gasses.
• When charging provide adequate ventilation to allow the
safe escape of explosive gases.
• Do not do anything to cause sparks near a battery. Keep
naked flames and cigarettes away from batteries.
• If acid contacts eyes or skin flush immediately with large
quantities of clean drinking water.
• After use wash out empty electrolyte bottles with water and
dispose of carefully - do not use empty electrolyte bottles
for any other purpose.
• Always keep batteries and electrolyte out of reach of
children.
• Dispose of old batteries carefully.
BATTERY MAINTENANCE
1. Keep the electrolyte levels about 6mm above the plates
and separators.
2. Keep terminal posts free of corrosion.
3. Keep battery clean and dry.
4. Do not leave machine switched on without the engine
running as this will discharge the battery.
5. Do not fast charge any battery over 18 months old.
6. Never add acid to a battery unless it has been lost through
spillage.
