CHARGING GEL/AGM (VRLA) BATTERIES
Charge the batteries each time the machine is used or when the Battery Charge Level Indicator (C3) is reading less than full.
WARNING!
Charge batteries in a well-ventilated area. If battery acid makes contact with your skin, flush the affected area with water for 5
minutes and seek medical attention.
Do not smoke while servicing the batteries.
When Servicing Batteries...
*
Remove all jewelry
* Do not smoke
*
Wear safety glasses, rubber gloves and a rubber apron
* Work in a well-ventilated area
* Do not allow tools to touch more than one battery terminal
at a time
* ALWAYS disconnect the negative (ground) cable first when
replacing batteries to prevent sparks.
* ALWAYS connect the negative cable last when installing
batteries.
CAUTION!
Your valve regulated lead acid (VRLA) battery will
deliver superior performance and life ONLY IF IT IS
RECHARGED PROPERLY! Under or overcharging
will shorten battery life and limit performance.
Be sure to FOLLOW PROPER CHARGING
INSTRUCTIONS! DO NOT ATTEMPT TO OPEN
THIS BATTERY! If a VRLA battery is opened, it
loses its pressure and the plates become oxygen
contaminated. THE WARRANTY WILL BE VOIDED
IF THE BATTERY IS OPENED.
If your machine shipped with an onboard battery charger do the following:
1 Turn the machine off at the Power Switch (H).
2 See Figure 4-4. Tip the seat forward for battery, charger access and proper ventilation, gas spring holds the seat open.
3 Unwind the electrical cord (18A) for the onboard charger and plug it into a properly grounded outlet. Refer to the OEM product manual for more detailed
operating instructions. While AC power is applied to the onboard charger all machine functions are disabled.
The Battery Charge Status Indicator (C3) will begin showing the batteries' state of charge. This indicates that the charging cycle has begun. As the charging
4
cycle continues, the battery charge level will fill in.
When the Battery Charge Status Indicator (C3) is completely filled, the machine senses fully charged batteries, however the charging process may not be
5
complete. Rely on the status lights on the Charger (18) (and its OEM manual) to verify when the batteries are completely charged. This may take several
hours depending upon the condition of the batteries before charging.
6 After charging is complete unplug the charger and wind up the Cord (18A). Wait at least 10 seconds before turning on the machine after unplugging the
charger.
If your machine shipped without an onboard battery charger do the following:
Turn the machine off at the Power Switch (H).
1
2 See Figure 4-4. Tip the seat forward for battery access and proper ventilation, gas spring holds the seat open.
3 Disconnect the batteries from the machine and push the connector from the charger into the Machine Battery Connector (19). Follow the instructions on the
battery charger and OEM product manual. SERVICE NOTE: Make sure you plug the battery charger into the connector that attaches to the batteries.
IMPORTANT: Make sure you have an appropriate charger for use on Gel cell batteries. Use only "voltage-regulated" or "voltage-limited" chargers.
Standard constant current or taper current chargers MUST NOT be used. A temperature-sensing charger is recommended, as manual adjustments are
never accurate and will damage any VRLA battery.
