BATTERY MAINTENANCE
Follow the SHUT DOWN PROCEDURE in the OPERATOR’S MANUAL before doing any
battery maintenance. For your safety always abide by the following:
Shield entire face, especially your eyes, and wear rubber gloves to avoid acid burns whenever doing
anything with the battery. Battery caps must be tightly in place if the battery has removable caps.
WARNING
: The battery contains sulfuric acid that can cause blindness and severe burns. Avoid
contact with eyes, skin, and clothing. If acid contacts eyes, call 911 immediately and flush eyes
with water for 15 minutes or until emergency medical help arrives. If acid contacts skin, flush area
with plenty of water. If acid is ingested, drink large quantities of water or milk then follow with
milk of magnesia, beaten egg, or vegetable oil, and get medical attention immediately.
Avoid contact with battery components. Wear rubber gloves and wash hands after handling any
battery components.
WARNING
: Battery posts, terminals, and related accessories contain lead and lead compounds,
chemicals known to cause cancer and reproductive harm. Acid can cause blindness and severe
burns if leaked from the battery.
Do not charge or jump-start the battery near flames or sparks, or while smoking.
WARNING
: Battery fumes are flammable and explosive. Avoid explosion hazard that could blind
and burn. Tools and jumper cable clamps can make sparks, so use them with care. Shield eyes
and face, and wear rubber gloves.
ELECTROLYTE LEVEL: Check the battery electrolyte level every 25 hours of machine use and
if necessary add distilled water following this procedure:
1.
Disconnect the battery cables, removing the negative cable first.
2.
Remove the battery from the machine.
3.
Clean the battery exterior with paper towels.
4.
If the battery posts and cable terminals are corroded, clean them with a wire brush cleaner
tool. A solution of four parts water and one part baking soda is helpful.
5.
Remove the battery caps.
6.
Slowly pour distilled water into each battery cell until the electrolyte level is up to the full line
indicated for each cell on the battery.
Do not overfill
. Overflow of electrolyte, which contains
sulfuric acid, can cause severe corrosion to the stump grinder.
7.
Reinstall the battery caps tightly in place.
8.
Apply a light coating of grease to the battery terminals to help prevent corrosion.
9.
Reinstall the battery securely into the stump grinder.
10.
