Machine Specifications and Operator Maintenance
6.7.1 Battery Charging (Daily)
When battery charger is to be used, charging harness must be plugged into a
grounded receptacle. If receptacle is not grounded and a malfunction should occur,
the machine could cause serious electrical shock.
For increased battery life:
• Batteries should be kept at highest state of charge permitted by availability at job
site and machine use. Charge batteries before they reach 20% state of charge. Avoid
completely discharging the batteries.
• Fully charge the batteries each day the machine is used.
• Charge the batteries at available times between use. Flooded lead acid/AGM
batteries do not develop a charging memory.
• If applicable, be sure the battery fluid covers the battery plates before charging. To
avoid overflow, do not top off the fluid level until after charging.
When adding distilled water to the batteries, non-metallic containers and/or
funnels must be used. Add water until electrolyte covers plates. Do not charge
batteries unless electrolyte covers the plates.
Note: To avoid electrolyte overflow, add distilled water to batteries after charging.
When adding water to the battery, fill only to level indicated or 3/8'' above
separators.
6.7.2 Battery Maintenance (Quarterly)
When adding distilled water to the batteries, non-metallic containers and/or
funnels must be used. Add water until electrolyte covers plates. Do not charge
batteries unless electrolyte covers the plates.
Note: To avoid electrolyte overflow, add distilled water to batteries after charging.
When adding water to the battery, fill only to level indicated or 3/8'' above
separators.
1. Open battery compartment cover to allow access to battery terminals and vent
caps.
