1. Introduction
We congratulate you on the purchase of the automatic chain
lubrication system "MOFESSOR“.
For a start, the system will not only extend the lifespan of your chain,
it will also reduce the maintenance expense of your motorbike. The
MOFESSOR is conceived to support you reliably on every mile you
go.
If you have any criticism, tips, improvements or a special wish, do not
hesitate to contact us.
2. Safety Instructions
2.1 Basic Safety Instructions
This manual contains the safety requirements for a proper and safe
use of the device. This manual, in particular the safety instructions,
has to be respected by the user.
The chain lubrication system MOFESSOR operates with oil. If the
installation is done improperly, an uncontrolled loss of oil can lead to
soiling the motorbike or even worse safety issues (e.g. oil on the tire).
For that reason, the system has to be checked carefully before every
departure and also after having done the first miles.
2.2 Intended Use
The chain lubrication system is intended for the use on chain-driven
motorbikes. For all otherpossible types of use, correctfunction cannot
be guaranteed. Its use is at your own risk and without any warranty.
This in particular means the use of non-authorized fluids (see chapter
3.3).
The installation and the use have to be done according to this manual.
In case of any improper use of the device or neglecting this manual
the manufacturer is not liable for possible damages.

3.3 Oil
We recommend the use of BEROTEC chain oil, tried and tested with
the MOFESSOR.
The use of other types ofoil is possible. However, so-called “biological
oils“ as well as sunflower oil and rape oil have to be avoided. These
kinds of oil have the tendency to gum and will block the system.
Solvent-based liquids are not allowed.
Viscosity recommendation:
Viscosity /40°C / ASTM D 7042: 100 mm²/s
Viscosity-index / ASTM D 2270: 135
Depending on the operating conditions and the installation, the
average oil consumption is about 1ml per 100 km.

3.4 Rain
While riding inthe rain, lubricity of the chain is wearing off much faster.
By using the integrated rain-mode of the system, the oil flow can be
increased. A quick push on the button of the switch increases the oil
flow by the factor eight of the normal amount. A red LED, integrated
in the switch, indicates if the rain-mode is active. The rain-mode will
be set back to normal by either pushing the button of the switch again
or by turning of the ignition. Also in dusty or dirty environment the rain-
mode can be used to increase the oil flow.
3.5 Flushing
A mode to flush the system can be activated easily. The button of the
switch has to be pushed and held for 4 seconds. If activated, the red
LED will give feedback by flashing fast. This mode opens the
dispensing valve permanently. This can be helpful in the following
situations:
Bleeding the system (see chapter 4.6)
Re-oiling a dry chain fast
Restoring lubricity after a long ride in heavy rain or dirt
Warning: This mode leads to a very high flow of oil. The rear wheel
can be soiled with oil. This is a safety danger. Use this mode with
caution while riding.
3.6 Temperature Influence
The common use of a motorbike lies in a temperature span between
-10°C and +50°C. Beyond these temperatures man and machine
reach the limits of what is bearable.
Within this temperature span, the viscosity of oil changes bythe factor
60. To guarantee a steady oil application on the chain, the control unit
is measuring the outside temperature permanently and adjusts the oil
flow automatically.

4. Installation
4.1 Preparations
There is no need for special tools. Often the needed tools can be
found in the on-board tool set of your motorbike. For some models
special installation manuals exist.
See our website for more information:
https://berotec.de/produkt/chain-oiler/?lang=en
The MOFESSOR is turned on and off with the ignition of the
motorbike. It is necessary to find a power supply on the motorbike
which is switched by the ignition. Often this is already prepared bythe
manufacturer of the motorbike (e.g. for navigation systems, often
called “ACC2”). Otherwise the power supply of the front- or taillight,
the mark lighting or the power supply of the horn can be used. The
forked current is very low (20mA), so there is no influence on the
electrical system of your bike.
4.2 Place of Installation
The MOFESSOR works gravity based. For that reason, it can be used
worldwide. To achieve its correct function, the oil tank has to be
installed higher than the dispensing valve (see chapter 3.2, Figure 1).
No part of the system should be mounted close to hot components
such as exhaust or engine. Under the passenger seat you may find
enough spacefor the installation. The self-adhesive foam can beused
for the installation to protect the parts from scrubbing.

4.3 Application Nozzle
The application nozzle is made of copper and can be easily bended
to optimal application position. It is not functional to bend a very tight
radius or to kink the tube. This will block the oil flow. The application
nozzle is a capillary tube and shouldn’t be shortened.
The oil outlet must be at the lowest point of the mounted application
nozzle, otherwise correct oil delivery will not be guaranteed.
The nozzle can be located in the area of the sprocket or the pinion.
According to experience, oil consumption is a little lower by placing
the nozzle on the sprocket. The disadvantage of this position is that
the nozzle is more exposed to dirt and can be misadjusted when
changing tires. Installation of the nozzle at the pinion is almost
invisible and protected.
Installation of the nozzle at the sprocket is the most effective way
bringing the oil on the chain. The oil is transported through centrifugal
force along the sprocket into the chain. The same principle works at
the pinion. But due to the smaller diameter and the higher rotation
speed, the centrifugal force is higher and a bit more oil gets wasted.
The best place for the installation of the nozzle always depends on
the motorbike.
For the installation of the nozzle, a nozzle mounting clamp and some
self-adhesive cable tie mounts are provided. When using the cable tie
mounts, the surface needs to be degreased properly. Bended or
structured surfaces are not suitable for the use of the cable tie
mounts. The processing temperature is at least 20 ° C.

4.4 Oil Tank and Dispensing Valve
The oil tank must be installed with the hose connection at the lowest
point. The golden ventilation of the tank must be at the highest point,
so that no oil can escape during driving.
Figure 2: Dimensions of the Oil Tank
To refill the system, a t-connector is placed between oil tank and
dispensing valve. The end cap, located at the end of the filler pipe,
needs to be attached. The removable end cap should be placed in an
accessible area, so refilling can be done easily. The oil flow direction
is marked with an arrow on the dispensing valve.
4.5 Electrics
The MOFESSOR is delivered completely wired and tested. Don’t
connect/disconnect the plugs in energized condition.
The following steps are necessary for the electrical installation:
Chose installation place for the control unit
Connect dispensing valve to the control unit
Place switch for rain-mode activation on the motorbike
(Recommendation: handlebar / field of view, use switch
holder) and connect the switch to the control unit
Avoid placing the cable of the switch close to the ignition

MOFESSOR
Manual
Warning: The wire connection at the backside of the switch is not made
to be bent forcibly. The switch will break and this is no issue of warranty.
We recommend laying the M8 connector side of the cable through the
motorbike and not the switch. The cable on the backside of the switch
needs to be mounted completely traction-free, especially with the
handlebar at maximum steering angle.
The control voltage cable (white/black with red connector)
needs to be connected to a 12V wire that is switched by the
ignition (see chapter 4.1). Use the red connecting terminal.
The red clip can be connected to a wire by closing it with a pair
of pliers with a cable in it. The red cable lug can now be
pushed into the red connecting terminal.
Last step: Battery connection cable with ring cable lugs need
to be connected to the battery (positive pole = red; negative
pole = black).
Note: Battery connection cable and control voltage cable can also be
connected together to a switched current source (for example, on-
board socket), as long as an adequate power supply (520mA) is
guaranteed.
4.6 Commissioning
Before using the chain lubrication system, the chain should be
cleansed. Otherwise old dirt and grease will come lose due to the
chain oil and get centrifuged on the motorbike. We recommend the
use of a chain cleaner.
The system can now be activated. If you turn on the ignition, the red
LED light inside the switch will flash once. This is a self-test of the
system. The system is now ready to go. You can also activate the rain
mode with a single push on the button of the switch.

Manual
The system needs to be bled after filling it for the first time or running
it completely empty (see chapter 5.2). Push the button of the switch
for 4 seconds. The red LED will start flashing. The dispensing valve
is now open. Wait until oil starts dripping out of the nozzle. If the oil is
very cold, you can speed up this procedure by taking the oil-filled
syringe and give the system a light over-pressure. Keep in mind to
close the golden bleeding valve of the tank with your finger if you do
this. When finished, deactivate the flushing mode with a push on the
button of the switch.
Warning: Before every departure have a close look at all parts of the
system, check if all tube connections are mounted properly and if there
is no leaking or malfunction.

5. Operation and Maintenance
5.1 Adjusting the Oil Flow
We recommend to initially set the rotary switch to level 1. This is the
setting for minimal oil flow. After 5 miles, check the amount of oil on
the chain and the whole system to ensure there is no malfunction.
After another 50 miles, start adjusting the rotary switch for a higher oil
flow. Find the optimal setting by turning the rotary switch step by step.
Keep in mind, changes in the oil flow need around 150 miles before a
valid evaluation is possible.
By following this procedure, soiling of the motorbike can be avoided.
Adjusting a high flowrate of chain oil can lead to the soiling of the rear
wheel. The oil flow has to be reduced immediately. A closed lubricity
on the chain rollers is sufficient and important.
The driver is responsible for a correct amount of oil. We are not liable
for damages caused by the oil flow being too low or too high.

5.2 Refill
Refilling the chain oil is easy and fast. The syringe can be raised
directly on the cap of the oil bottle. Push the syringe into the small
opening of the cap, turn the bottle upside down and raise the syringe.
The end cap of the filler pipe can be removed by pushing the locking
edge. With the syringe, oil can be filled into the system. The oil tank
is bleeding automatically. This has to be repeated until the oil tank is
full, but don’t overfill the tank, otherwise oil will leak out of the
ventilation of the tank.
5.3 Check and Maintenance
The MOFESSOR is maintenance-free. After the installation do some
visual inspection to check the correct setting of the oil flow.
The oil level of the oil tank should be checked and refilled every 1700
miles (long range tank every 3400 miles). Thus you can avoid the
system running dry.
