Rungu Dualie Maintenance, Care and Repair
Before Each Ride
See section labeled “
Securing your Dualie
When riding the Dualie in areas where theft is a concern, use appropriate cable or chain locking devices
and make sure to thread the cable/or chain through the frame, wheels and saddle/seatpost to avoid
quick removal.
Standard Bearer Machines recommends you use the Password feature found in the display settings
described in an earlier section of this document.
After Each Ride
1.
Clean and inspect Dualie. Hose off (Use a shower mode or light spray, avoid powerful spray
settings) or wipe down DUALIE 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. See more about chain maintenance in Chain Maintenance
section below.
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 Dualie within the next few days.
3.
If you plan to not use the Dualie 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 Dualie 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 Dualie 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 Dualie.
For best results, every month you don’t use
Dualie, 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.
