CHARGING WET BATTERIES

Charge the batteries each time the machine is used or when the Battery Indicator (K5) is reading less than full.
To Charge the Batteries...

2 Open Side Access Panel (27) and push the connector from the charger into the Battery Connector (20).
3 Follow the instructions on the battery charger.

WARNING!
Do not fi ll the batteries before charging.
Charge batteries in a well-ventilated area.
Do not smoke while servicing the batteries.
When Servicing Batteries...
• Remove all jewelry
• Do not smoke
• Wear safety glasses, rubber gloves and a rubber apron
• Work in a well-ventilated area
• Do not allow tools to touch more than one battery terminal at a time
• ALWAYS disconnect the negative (ground) cable fi rst when replacing batteries to prevent sparks.
• ALWAYS connect the negative cable last when installing batteries.
CAUTION!
To avoid damage to fl oor surfaces, wipe water and acid from the top of the batteries after charging.

CHECKING THE BATTERY WATER LEVEL

Check the water level of the batteries at least once a week.
After charging the batteries, remove the
vent caps and check the water level in each
battery cell. Use distilled or de-mineralized
water in a battery fi lling dispenser (available
at most auto parts stores) to fi ll each cell to
the level indicator (or to 10 mm over the
top of the separators). DO NOT over-fi ll
the batteries!
CAUTION!
Acid can spill onto the fl oor if the batteries
are overfi lled.
Tighten the vent caps. Wash the tops of
the batteries with a solution of baking soda
and water (2 tablespoons of baking soda to
1 liter of water).
