Temperature and Humidity
Operate the Firefly
TM
2.5 only at temperatures from 14 to 104 degrees F (-10 to 40 degrees C). Charge the
battery at temperatures from 41 to 77 degrees F (5 to 25 degrees C). Store the battery at temperatures
from 14 to 77 degrees F (-10 to 25 degrees C). The Firefly
TM
2.5 is water-resistant, not waterproof. A light
drizzle is not detrimental, but we recommend covering the battery and controller with a plastic bag if
you’re caught in heavy rain. Clean the Firefly
TM
2.5 with a damp cloth. Do not soak or spray with water or
use detergent. Lubricate as needed after cleaning.
Tighten axle nuts
Tighten both nuts on the ends of the axle monthly to a torque of 30 ft-lb (40 Nm). Failing to tighten the
axle nuts can result in the axle turning, which will cause the motor cable to wrap around the axle, pulling
the cable out of the motor and damaging it.
Tighten hex bolts
Tighten the bolts on the mounting clamps and U-bar on a weekly basis when using the Firefly
TM
2.5
regularly. All four hex bolts on the mounting clamps and all twelve hex bolts on the U-bar must be
tightened using the torque handle set to 12 Nm of maximum torque (included in the set of accessories).
Do not adjust Torx bolts
Do not attempt to adjust any Security Torx bolts (which have six-pointed star pattern heads and a pin the
middle). These bolts have been adjusted at the factory and do not need any additional adjustment.
Battery care
Use only the supplied charger to charge your battery. Remove the battery from the charger when it is
finished charging; never leave the battery plugged into the charger overnight or unattended. Never
charge the battery near a bathroom, sink, drain, microwave, heater, fireplace, air conditioner, or other
appliance. Avoid leaving the battery in an automobile or garage, as it could be exposed to excessive
temperature or moisture. Store the battery in a cool, dry place away from heat, moisture, and sunlight.
Never leave the battery fully charged or fully depleted while in storage, as this may decrease the overall
lifespan of the battery. When in storage, the battery should be charged to about 65%, and then charged
every two months for 30 to 45 minutes in order to maintain this level of charge.
Damaged or missing parts
Immediately replace any damaged, missing, or badly worn parts with manufacturer-approved parts.
Please contact your dealer or: support@riomobility.com for information on replacement parts.
Flat tires
Inflate the tire to 35 psi (2.4 bar) of air pressure. Screw the L-shaped valve extender onto the tire's valve
stem if you are unable to insert a pump head onto the valve stem without the extender.
Keep the box
We recommend keeping the cardboard box the Firefly
TM
2.5 was shipped in, for convenient storage of
the Firefly, accessories, and tools. The box can also be used to ship the Firefly to our shop for repairs.
