EMU Maintenance

 

Avoid completely discharging the battery

Unlike NiCad and SLA batteries, lithium-ion batteries do not have a ‘charge memory.’ This means that you do not need to run your battery down to empty. In fact, you should NEVER allow a lithium-ion battery to completely discharge.

If a lithium ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger and battery will then be of no use and should be discarded. This is the nature of this type of battery and is not a manufacturer defect. The original one-year warranty will not cover the replacement of a new battery and/or charger if the need for a replacement is due to the user allowing the battery to completely discharge. NEVER attempt to recharge deeply discharged lithium-ion batteries.

The exception is when you need to re-calibrate the power gauge. Your power guage is located on the pod that sits atop the handle bars. This is where you can see how much power remains in the battery while the EMU Trike is turned on. You will need to periodically ‘recalibrate’ this for a more accurate measurement display. Follow these steps to do so:

  • After approximately 30 charges, allow your lithium-ion battery to discharge just past the LOW level on your power guage
  • When the word EMPTY lights up, plug in your EMU Trike to recharge the battery
  • This process, done after every 30 charges, will re-calibrate the power gauge for more accurate readings.

 

Do NOT store a battery at full charge

All types of batteries will begin to self-discharge while not in user, therefore, if you know that your EMU Trike is going to sit for two-weeks or more, you will want to store it with SOME charge remaining. The recommended status of charge when storing a lithium-ion battery is approximately 40-50%. This will allow for a slower self-discharge than if stored with the battery at 100%. We do not recommend that you store your lithium-ion battery for more than 2-3 months without recharging back to 40-50%. Not only will this ensure that you will get a longer life out of your battery, but it will also help prevent a full self-discharge which may render your battery useless. For extended periods of non-use, it is best to remove the battery from the unit and store it in a cool and dry environment (the cooler the better but no less than 35F).  The ideal temperature for storing a lithium-ion battery long-term is approximately 65F with the status of the charge between 40-50% for 2-3 month intervals. Following any period of extended non-use, be sure to recharge the battery prior to using your EMU Trike.

 

Always monitor the charging process of your EMU Trike

When charging any type of battery, do not leave it unattended. You should monitor the status of the charge anytime the EMU is plugged in. Once the charge is complete, always disconnect the charger from both the battery and the wall.

It is important to note that overcharging any type of battery can reduce its efficiency, shorten its lifecycle, and can even lead to a meltdown – creating the possibility of a fire hazard. Discontinue use of the battery and charger if either gets excessively warm. Regardless of the many safety measures put in-place by the manufacturer, never leave your battery unattended while charging.

 

Always turn off the power while charging

Make sure that the power on your EMU Trike is in the OFF position while charging the battery. This allows the battery to reach the threshold voltage unhindered. A parasitic load confuses the charger.

 

Always disconnect the charger when complete

When you connect the charger to the EMU Trike, and it is plugged into the power source, you will hear the soft hum of the cooling fan. You will also see that the charger’s two indicator lights are illuminated red. One red light indicates that the electric power is reaching the charger and the other red light will turn green once the battery is fully charged. To ensure your safety, once the battery is charged to your satisfaction, ALWAYS unplug the charger from the trike and the wall.

 

Never use a different charger

Not all chargers are compatible with the lithium-ion battery installed in your EMU Trike. Therefore, you must use ONLY the charger that originally came with your EMU Trike. To avoid damage to the battery, charger, property or person, do NOT use an alternative charger. Please contact EMUWest if you need a replacement charger. Use of a different charger with you EMU Trike is done so at your own risk and will result in an immediate void of your warranty and user will hold harmless EMUWest and American Scooter Company should damage to product, person, or property occur.

 

Water & Electricity do NOT mix

Your EMU Trike is an electric powered vehicle. As with anything electronic, you want to avoid the chance of electrical parts becoming affected by humidity, excessive moisture and of course any form of water, including falling rain or standing puddles.

If you are riding your trike and it begins to rain, find shelter as quickly as possible and be sure to wipe down your trike with a dry towel. Do no use a water hose to wash your EMU Trike. Instead, use a damp cloth to wipe off any dirt or debris. If you suspect that water or excessive moisture may have leaked inside the battery cover, be sure to remove the battery cover and dry all electrical components prior to using the Trike again.

 

Take care of your pneumatic tires

We use pneumatic (air) tires instead of solid rubber tires because air tires absorb shock better and therefore offer a more comfortable ride. To ensure rider safety and comfort, all tires on the EMU Trike® should be at 35psi.

As with any air-filled tire, there may be times when they get punctured by debris (such as nails). Unlike other scooters, our two-rear tires have what we call 'split-rim' wheels. This means that when you need to change the inner tube or tire, you no longer have to struggle to pull and pry them off of the wheel. The 'split-rim' wheel that sits inside of the tire/tube is able to be split apart, allowing the tire/tube to be removed and replaced easily and quickly. Step-by-step instructions for changing the rear-tires are posted below. 



Note:  Unlike other scooters or bikes, the EMU Trike does not require you to periodically lubricate the wheel bearings, as our wheel bearings are self-lubricating and sealed for protection from the elements.
