2 Raket 95 Manual - English
Congratulations, you have made a
good choice when you picked our
engine Raket 95.
Now we beg you to read through this
User Manual before you start using
the engine. The manual is an impor-
tant part of our delivery and it is a
proof of our endeavour to deliver a
good and safe product that both you
and we can be proud of.
Raket 95 is a brand new type of kart
engine. It is a two stroke engine, but it
is built on a completely new principle
for scavenging, which is called Dual
Charge. Thanks to this the Raket
95 engine has much less exhaust
emissions than any other comparable
kart engine. Dual Charge also means
a number of other advantages, e.g.
lower fuel consumption and improved
oiling of all bearings in the crankcase.
Should you one day sell your Raket
95 engine, you should pass on this
User Manual to the new owner.
If the User Manual has got lost you
can order a new one free of charge
from Radne Motor AB.
Owners Manual Raket 95

Under no circumstance is it
allowed to change the original
design of the engine without
a written acceptance from the
manufacturer. You should always
use original spare parts. Unau-
thorised changes or non original
spare parts can lead to serious
damages.

1. Safety
1.
Raket 95 engines including accessories,
as supplied by Radne Motor, are only in-
tended to be assembled on a kart and for
the purpose of driving the kart. Any other
use is forbidden unless written approval
has been received from Radne Motor.
Radne Motor accepts no responsibility
whatsoever for anything that may happen
if a Raket 95 engine is used for any other
purpose than that for which it is speci-
cally intended.
2.
A kart that is equipped with a Raket 95
engine can attain speeds at which the
driver is exposed to obvious danger to life
and limb if the kart is handled in an irre-
sponsible manner. Radne Motor accepts
no responsibility whatsoever for injuries
to people or damage to property that may
arise if a kart that is equipped with a Ra-
ket 95 engine, either directly or indirectly
is the cause of an accident or damage as
a result of carelessness or negligence on
behalf of the driver.
3.
During normal use, some parts in a Raket
95 engine become so warm that they can
cause burns to people who come into
contact with the warm parts. Examples of
such parts are the silencer and cylinder. It
is up to the driver to ensure that the kart
is equipped with appropriate protection
so that contact with warm and hot objects
is avoided, and to act in an appropriate
fashion so that such possible burn injuries
do not occur. Radne Motor accepts no
responsibility whatsoever for injuries that
may occur as a result of a person coming
into contact with the hot or warm parts of
a Raket 95 engine.
4.
During the normal use of a Raket 95
engine installed on a kart, there is a risk
for personal injuries that may occur as
a result of body parts or objects being
trapped between, or rubbing against, the
engine’s rotating parts. An example of this
could be getting a nger stuck between
the sprocket on the outbound axle and
the chain that drives the rear axle. It is
up to the driver to ensure that the kart
is equipped with appropriate protection
so that such incidences of contact are
avoided, and to act in an appropriate
fashion so that no injuries of this type
occur. Radne Motor accepts no respon-
sibility whatsoever for injuries to people
that may occur as a result of something
becoming trapped between the rotating
parts of a Raket 95 engine.
5.
A Raket 95 engine is propelled using a
ammable fuel – alkylate petrol or 95
octane petrol. Careless handling of the
fuel can lead to res that can cause injury
to people or damage to property. Radne
Motor accepts no responsibility whatso-
ever for accidents and injuries that may
occur as a result of careless handling of
fuel, for instance when lling the fuel tank,
incorrect mounting of the fuel tank onto
the kart, inappropriate construction of the
fuel tank, a fuel tank made of inappropri-
ate materials or the existence or use of
IMPORTANT

Raket 95 Manual - English 5
inappropriate materials in, or with the
drawing of, a fuel line.
6.
Raket 95 is equipped with an electric
starter system consisting of a starter
motor and a starter battery. The battery is
of the NiMH type (Nickel-metal hydride).
Please refer to the separate section in this
manual regarding handling and care of
the NiMH battery that is included with the
delivery of a Raket 95 engine. Radne Mo-
tor accepts no responsibility whatsoever
for accidents or injuries that may occur to
people or property if any battery is used
other than that which is supplied with the
original delivery or as an original spare
part battery.
7.
The driver is responsible for the mount-
ing of the battery, battery box and cables
between the battery box and the starter
motor, in accordance with the instructions
provided in this manual. Radne Motor
accepts no responsibility whatsoever for
accidents and
injuries that
may occur
as a result
of incorrect
mounting of
the bat-
tery, battery
box and/or
the cables
between the
battery and
the starter
motor.
8.
The charging
and storage
of the NiMH
battery should occur in accordance with
the instructions provided in this manual.
Radne Motor accepts no responsibility
whatsoever for injuries to people or dam-
age to property that may occur as a result
of incorrect handling, storage or charging
of the Raket 95 NiMH battery.

2. Instructions for handling
and charging a Raket 95
starter battery.
PLEASE NOTE: These instructions
regarding the handling of a Raket 95
starter battery are an important part of
Radne Motor’s delivery of the Raket 95
kart engine. These instructions contain
information about handling of the battery
and the charging of the same. Before you
may use the NiMH battery it is important
that you read these instructions in their
entirety. If in the future you sell your Raket
95 engine together with its starter battery,
then you must ensure that the new owner
receives these instructions.
IMPORTANT! Radne Motor accepts no
responsibility whatsoever for damages to
a Raket 95 engine that may occur if you
use any other battery than a Raket 95
original battery.
If you have previous experience of lead-
acid batteries then please be aware that
NiMH batteries are radically different
from these. As long as a NiMH battery is
used correctly then it is a very good and
environmentally-friendly source of power
that is far superior to both lead-acid and
nickel-cadmium batteries. However, if a
NiMH battery is not handled correctly and
in accordance with these instructions,
such incorrect handling may drastically
shorten the battery’s lifespan, or else
cause injury to people or damage to
property.

Safety instructions for the use of
the battery and the charging of the
battery:
1.
Read these instructions in their entirety
before you begin to use the NiMH battery.
2.
The handling and care of the NiMH bat-
tery should never be entrusted to children
unless there is a supervising adult in
attendance.
3.
Always check that the NiMH battery is in
good condition every time before using
it. If you see that the battery is mechani-
cally damaged, or if it appears to have
expanded in volume or if electrolyte (a
sticky gel-like substance) has penetrated
the battery, then you should discard the
battery immediately.
4.
A NiMH battery should not be thrown out
with household garbage but should be
taken for recycling in accordance with
your local guidelines regarding the man-
agement of recyclable waste.
5.
A NiMH battery should never be shorted
or exposed to high levels of heat.
6.
A NiMH battery should never be over-
charged. That is why you should always
use the Raket original battery charger that
automatically stops charging when the
battery has reached its full capacity.
7.
A NiMH battery should not be discharged
so that the terminal voltage drops to be-
low 11.0 volts. If you discharge the battery
too deeply then one of the battery’s cells
may be damaged in which case you will
no longer be able to recharge the battery
to its full capacity.
8.
A NiMH battery should not be charged
until most of its capacity has been used
up. At that point the terminal voltage will
have dropped to 12.0 volts. In practical
terms this means that you can start your
kart approx. 50 times before you need
to charge the battery. Try to get into the
habit of charging your battery after you
have started the kart 35 – 45 times.
9.
You should always charge the battery
using the original special charger that is
supplied with the delivery of a Raket 95
engine. The charger is an intelligent-type
charger which means that it initially charg-
es with a high current until the battery
reaches maximum capacity. After that the
charger switches over to trickle charge
mode. If you were to use a charger that
does not have this automatic function
then you would almost certainly “burn-out”
your battery because of overcharging.
10.
Never charge a battery that is warm. Let
the battery cool to normal room tempera-
ture before you start to charge it again.
11.
The time required to charge a battery that
is typically discharged is 5 hours. When
the charger notices that the battery is
fully charged it switches to trickle charge
mode.

8 Raket 95 Manual - English
12.
When charging the battery, the charger
should be connected to the charger plug
that is located on the battery box. If the
battery is to be charged once it has been
removed from the box then the charging
process should occur on an inammable
surface. Connect the charger’s positive
terminal to the battery’s positive terminal
and the battery’s negative terminal to the
charger’s negative terminal. If the charger
is connected incorrectly it is most likely
that both the battery and the charger will
immediately and irrepairably damaged.
13.
The battery does not need to be super-
vised during charging. The automatic
functionality of the charger takes care of
any need for supervision.
14.
The battery should not be altered in any
way, for instance by taking it apart and
putting it back together in a different
conguration.
15.
It is not permitted to solder the battery. If
one of the connection cables should come
loose from the battery as a result of care-
less handling then it should be disposed
of immediately.
16.
If a re should start in a NiMH battery
then the re should be extinguished with
sand or alternatively the battery should be
cooled down by using a CO2 re extin-
guisher.
17.
If the battery’s electrolyte should come
into contact with a person’s hands then
the electrolyte should be immediately
washed away to avoid any burns to the
skin. If someone were to get electrolyte
in their eyes then assistance from a
specialist eye doctor should be sought
immediately.
18.
Prior to winter, when you are no longer
using your kart, it is important that you
charge your battery before you put your
kart into storage for the winter. If you
store away your kart in the autumn with
a discharged battery then the battery will
almost certainly be inoperable when you
take out your kart again in the spring. For
this reason you should allow your battery
to remain charging on trickle charge mode
during the period that you will not be us-
ing it.
19.
If your kart is to be stored in cold stor-
age, in other words a storage area where
minus temperatures may occur, then you
should remove the battery and store it
somewhere at normal room temperature.
20.
For information regarding handling of
the charger we refer you to the general
instructions that can be found on Mascot’s
website. Please see: http://www.mascot.

Installing the NiMH battery.
1.
The battery is delivered in a battery box
made of extruded aluminium.
2.
The battery box is to be mounted onto a
console that is in turn to be mounted onto
the frame to the left of the driver’s seat,
using the supplied mounting components.
3.
The start button and the charger plug can
be found on the battery box. In the box
there is also a 40 A fuse that prevents the
battery from being destroyed if a short
should occur outside of the battery box.
The fuse may only be changed for an
identical fuse that can be purchased as a
spare part from a Raket reseller.
4.
A cable leads from the battery box which
should be connected to the starter motor.
There is a plug on the cable that should
be connected to the equivalent plug on
the starter motor.
5.
The cables between the battery box and
the starter motor should be carefully
fastened to the frame by using suitable
cable clips or ties. The cables should
be fastened in such a manner that they
cannot come into contact with any hot or
warm parts of the engine that might melt
the cable casing, nor with any moving
parts that might render holes in the cable
casing.

3. Instructions for mounting
the Raket 95 engine onto the
kart.
The process for mounting the Raket 95
engine onto your kart can of course vary
somewhat depending on what type of kart
you have. Below we provide some advice
and guidelines that are normally appli-
cable to most types of karts.
1.
The Raket 95 engine is designed to t di-
rectly onto the engine support that already
exists on your kart. You will need four M8
Allen (hexagonal) bolts in order to attach
the engine to the engine support.
2.
Your engine has an engine sprocket with
11 teeth. It is normally a good idea to try
an 80-tooth sprocket on the rear axle,
but then it is of course up to you to test
different settings for different tracks. A
curvy track may require a larger sprocket
= more teeth, while a straight and long
track may require a smaller sprocket on
the rear axle.
3.
The great majority of karts have a holder
for the silencer as standard, and the ac-
companying silencer is suitable for use
with such a standard holder. It comes
with three springs that hold the silencer
against the engine’s exhaust pipe, and it
will require two slightly longer springs to
hold the silencer in the support, for which
you can use the kart’s standard springs.
4.
A holder for the throttle cable can be
found between the carburettor and the
carburettor ange, while a lever with a
holder for the cable can be found on the
throttle shaft.
5.
You need to have a CIK-approved inlet
silencer to be able to drive and race your
kart. There are several different models
available and all are suitable for use with
the ange on the inlet crown.
6.
How you will then fasten the inlet silencer
to your kart depends on the type of inlet
silencer that you have chosen. We recom-
mend that you are careful when it comes
to fastening the inlet silencer since this
normally is required to absorb quite hard
knocks. We can certainly recommend
the use of Radne Motor’s holder (article
number 5208).
7.
When it comes to mounting the battery,
battery box and the connection between
the battery and the starter motor, a de-
scription of how to do this can be found in
a separate section of this manual.
