WARNING
Do not top the battery up with acid. The electrolyte could boil out and burn you.
1. Make the machine safe.
2. Open the battery compartment cover.
3. Remove the vent caps.
4. Check the electrolyte level.
4.1. The minimum level is at the top of the plates.
4.2. If necessary, add just enough distilled water to cover the plates at this time.
5. Install the vent caps.
6. Put batteries on a complete charge before adding any additional distilled water.
7. Remove the vent caps.
8. Add distilled water until the electrolyte level is below the bottom of the fill well by the specified value.
Distance: 3.175mm
8.1. If necessary, use a piece of rubber as a dipstick to determine this level.

Check (Charge Level)
WARNING Do not connect the charger when the batteries are not connected. Doing so could result in
danger of live terminals from the charger.
Do not carry out maintenance on a machine whilst the charger is connected to an external power supply
(i.e. do not work on a live machine). Cables from the charger to the batteries may remain live even if the
batteries are disconnected/removed from the machine. There is a risk of serious electrical shock.
