Safety Instructions DANGER This safety symbol means danger. When you see this symbol, carefully read the instructions that follow. Failure to obey the instructions could cause serious permanent injury, disability, or death. WARNING This safety symbol means warning. When you see this symbol, carefully read the instructions that follow. Failure to obey the instructions can result in serious injury. CAUTION This safety symbol means caution.
Think Safety First (continued) Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes and clothing. Battery gases can explode. Keep cigarettes, sparks and flames away from the battery. Avoid injury from lithium-ion batteries… If any smoke is observed, call the local emergency services immediately. Always service lithium-ion batteries with the machine parked near a service door large enough to move the product or battery outside in case of an emergency and keep a fire blanket nearby.
Think Safety First (continued) penetrate the skin and cause serious injury. Seek medical attention right away if hydraulic fluid gets in the skin. Personal Protective Equipment… Tie back long hair, and do not wear loose clothing or jewelry. Use appropriate personal protective equipment (PPE) for protecting yourself from potential hazards in the environment in which you will work. Each process outlined in this manual may need different PPE to protect the service person.

General Troubleshooting Problem The tool will not operate Possible Cause Corrective Action The charger is not charging the battery. 1. Is the charger physically damaged? If yes, replace the charger. 2. Check if LEDs light up on the battery. If the LEDs do not light up when the battery State-of-Charge (SOC) button is pressed, replace the battery. 3.

See Operator’s Manual for additional information. Battery Architecture Inside the battery pack are the cell/power pack and BMS (Battery Management System) combined to ensure the battery in the tool works the way it’s supposed to. Cell/Power Pack The first component of the battery pack is the cell pack. Cell packs come in a variety of formats, different shapes and sizes, for different applications.
Features Managed by Product Features managed by the product include tool operations and power usage control. The BMS does not tell the tool what to do and it does not dictate how much power is being used, the tool does. Battery Configuration When thinking about battery configuration, the 3 key terms are: voltage, amp hours, and watt hours. Individual cylindrical cells are configured in parallel and series to form a battery pack.

Service and Repairs Battery and Charger g336764 Figure 6 At 60 VDC the charger will indicate a full battery. If left on the charger, the battery will continue to charge for a period of time bringing the battery voltage up to 62 VDC. A battery with a reading of under 40 VDC has been over discharged and will likely not recover requiring replacement. The 60v batteries have 4 terminals. To test the battery voltage, place a multimeter on the DC voltage auto range.
