0.2 General safety warnings for repair personnel
Before working on the scooter and even when preparing any repair, make
sure you understand the basic workshop rules for providing a safe
environment for the execution of repairs. Such workshop rules may include
wearing proper clothing to prevent the risks posed by sharp objects or heavy
equipment or parts necessary for the execution of a repair.
The scooter operates at voltages below 60V and therefore does not fall under the
classification of high voltage. However, some precautions need to be made when working on
the scooter in order to prevent electrical shock or other types of injury.
● When working on any element usually covered by the body of the scooter, turn off the
scooter, detach the battery from the scooter and then turn the scooter back on for at
least two seconds to discharge any electricity stored in the electrical components.
● Wear safety gloves when performing any type of work on the scooter to prevent cuts
as well as provide additional protection against electrical shock.
● Protect your eyes with proper safety goggles or glasses when performing steps such
as drilling, hammering, and polishing.
● Wear a safety mask with an air filter when applying and type of spray, especially
when working in an enclosed environment. Generally all types of work involving
sprays should be performed in a well-ventilated environment.
● Wear a safety helmet also for short test drives as some unexpected behavior of the
scooter after a repair can lead to a loss of control and result in a fall or crash.
● Carefully follow all of the instructions laid out in this repair guide to ensure the proper
reassembly of all parts. Pay attention also to applying the proper torque to all screws
and bolts, which have been worked on during the repair. A list of all relevant torque
values can be found in the according chapter of this repair guide.
● Make sure to use only parts provided by unu to ensure proper quality and fit of the
parts. We advise strongly against the use of inferior parts, even if they appear to be
fitting with the scooter.

1. Part replacement
The following articles describe the work needed for the detachment of each part from the
scooter a group of its parts. For reassembly execute the steps in reverse order, unless
otherwise specified. The listed durations describe the time needed for dis- and reassembly
combined. The durations do not include the time needed for the preparatory steps.
1.1 Fixtures
1.1.1 Rear handhold
Duration: 4 minutes
Preparatory steps: None
Work steps
Remove the four screws on the underside of the handhold.
With the screws removed, stretch the ends of the handhold away from the bodykit and pull
the handhold towards the rear to remove it. If you can’t find the right angle for taking off the
handhold, look at the angle at which the middle part of the handhold enters the bodykit. It is
only slotted in and does not need to be unscrewed anywhere.
