Battery Maintenance
The batteries are deep cycle 12 volt batteries. The lifetime of the batteries is limited by the number of
charges the batteries receive. To get the most life from the batteries, charge them when the battery
discharge LED(Red) starts to blink (20% charge left). Use only the on-board battery charger supplied to
charge the batteries. Periodically clean the top surface of the batteries and the terminals, and check for
loose connections. Use a strong solution of baking soda and water. Brush the solution sparingly over the
battery tops, terminals, and cable clamps. DO NOT ALLOW ANY BAKING SODA SOLUTION TO ENTER
THE BATTERIES! Use a wire brush to clean the terminal posts and cable connectors. After cleaning,
apply a coating of clear battery post protectant to the terminals and the cable connectors. Keep the tops
of the batteries clean and dry. To prevent a possible short circuit, keep all metallic objects
off the top of the batteries. Replace any worn or damaged wires.
.
Lead Acid Batteries
Never add acid to the batteries, only distilled water. Always keep the battery caps on, except when adding
water or taking hydrometer readings. Check the electrolyte level in each battery cell before and
after charging, and after every 50 hours of operation. Do not charge the batteries unless the fluid is
slightly above the battery plates. If needed, add just enough distilled water to cover the plates.
Never add
acid
to the batteries. Do not
overfill.
Measuring the specific gravity, using a hydrometer, is a way to determine the charge level and condition
of the batteries. If one or more of the battery cells test lower than the other battery cell (0.050 or more),
the cell is damaged, shorted, or is about to fail
.
Sealed batteries no additional maintenance required.
CAUTION!
When working with batteries, always wear eye protection and protective clothing.
CAUTION!
Batteries emit Hydrogen Gas. NO SMOKING!
CAUTION!
Battery damage will occur if the electrolyte level does not cover the battery plates.
CAUTION!
Machine and/or battery damage can occur if the electrolyte level is above the bottom of the
tube in each cell.
CAUTION!
Never use tap water to fill battery cells. Tap water contains contaminants that will damage the
battery. Only use distilled water to fill battery cells.
Repacking the Machine
Refer to Unpacking section on page 5 and repack machine using original packing materials and
container.
Transporting the Machine
When shipping the machine, make sure the batteries are disconnected and the machine is secured in the
transporting vehicle.
