LUBRICATION
REAR CASTER
The rear caster has one grease fitting on the
caster swivel. Lubricate the caster with a grease
gun containing Lubriplate EMB grease every 100
hours of machine operation.
BATTERIES
The batteries are unique in that they hold their
power for long periods of time. 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
indicator needle remains in the red zone of the
indicator.
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 the 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.
Keep all metallic objects off the top of the
batteries, which may cause a short circuit.
Replace any worn or damaged wires.
