Rungu Maintenance
1.
ALWAYS check rear axle nuts BEFORE AND AFTER riding to make sure nothing is loose. Riding at
high speeds induces vibrations which may loosen components on the bike. This includes wheels,
the battery case, brake system, etc. If the nuts are not tight on the electric wheel, the axle can
spin in the dropouts leaving broken wires and damaged forks. These nuts must be very tight to
assure the proper performance.

DROPOUTS OR MOTOR CABLING!
2.
ALWAYS store and charge your batteries in a cool, dry place. Failure to do so will decrease
performance and the life of the batteries.
3.
DO NOT store lithium batteries at a fully charged state (40%-60% is ideal)
4.
ALWAYS check the integrity of the battery case and battery system. Make sure it is securely
fastened to the bike
5.
Check spokes on all three wheels. The electric wheel often requires more attention due to the
torque of the motor. Spoke and wheel maintenance are part of a normal bicycle maintenance
procedure and will be accelerated with an electric motor. Do not take chances with the spokes
and if you think they are loose, chances are you are correct. The spokes should all have the
same tension. If they are loose, tighten them yourself, or take it to your local bike shop to get
fixed.
6.
Check the pressure in your tires. The required pressure can be found on the sidewall of the tire.
Normal pressure is 5-10 PSI. Though the tires perform better in sand and deep snow at lower
pressures, pressures may cause sidewalls to collapse, and that is how most blowouts occur.
NOTE: HPC and Standard Bearer Machines are NOT RESPONSIBLE FOR FLAT TIRES!
7.
Check all electrical connections making sure that they are all tight. Bad contact means energy is
wasted as heat, which can cause a breakdown of wire insulation. Any wire with melted
insulation indicates a poor connection nearby. Disconnect the batteries and do not operate if
insulation is melted or wire is exposed.
