Rungu Electric Juggernaut Maintenance and Care
Before Each Ride
See section labeled “
After Each Ride
1.
Clean and inspect Electric Juggernaut. Hose off (Use a shower mode or light spray, avoid
powerful spray settings) or wipe down Electric Juggernaut and dry it with a towel. Look for any
damage to the frame or components that may need maintenance.
2.
Wipe and lubricate the chain. Depending on the riding environment apply a dry or wet lubricant
after wiping the chain clean and dry. We use brands like Boeshield T-9 and White Lightning;
there are others with similar reputations available worldwide on line.
Battery Care
There are three rules to extend battery life in day to day use:
1.
Charge the batteries in a cool, dry location. Heat is not a friend of the charger or the battery.
2.
Only fully charge the batteries if you plan to use the Electric Juggernaut within the next few
days.
3.
If you plan to not use the Electric Juggernaut for more than a few days, keep the batteries
charged around 50% of their capacity (Voltage level of 50-52 V) and recharge the battery the
day before your next ride.
CAUTION: IT IS IMPORTANT THAT THE BATTERY CHARGER GETS AIR FLOWING OVER THE
HEATSINK AND IS OUT OF DIRECT SUN TO AVOID OVERHEATING OR BATTERY FAILURE
WARNING: NEVER CHARGE BATTERIES AT TEMPERATURES AT OR BELOW FREEZING (32⁰F OR 0⁰C).
CHARGING AT THESE TEMPERATURES CAUSES PERMANENT DAMAGE TO THE BATTERY REDUCING LIFE
AND CAPACITY. BATTERY DAMAGE IS EXCLUDED FROM YOUR WARRANTY.
Storage When Not Using Electric Juggernaut for Periods of Two Weeks or
Longer
Standard Bearer Machines selected these batteries and the electrical system to be as maintenance free
as possible. In the event you plan to not use the Electric Juggernaut for a period of more than three
weeks, open the battery case (or cases), disconnect the battery from both connectors, and remove the
battery(ies) and store it (them) with ~50% charge (around 50-52V). For long term storage (for the
winter) store batteries in a room temperature location and away from Electric Juggernaut. For best
results, every month you don’t use
Electric Juggernaut, hook the battery up to the charger for 10-20
minutes as the battery will lose charge over time and this will allow you to put some extra charge in the
battery and balance the cells.
Note: You can purchase an outlet timer that switches the charger on every week for a period of 10
minutes and keep the charger connected to the battery. In this situation, the charger is only powered
by AC when the outlet timer is on.
