Workload adjustments
When pedaling the subject stores energy in the
flywheel. The flywheel is then braked by means
of a brake belt/cord which runs around the fly-
wheel. The workload is changed either by using
other pedaling speed or by increasing or decrea-
sing the tension of the brake belt/cord against the
flywheel by place weights in the weight basket.
Weights are in sizes 1 kg, 0,5 kg and 0,1 kg. This
makes it possible to vary the workload from 1 kg
up to maximum 12 kg in steps of 0,1 kg. NOTE:
1 kg is the lowest work load that can be set as
this is the weight of the basket itself. A weight
basket that only weighs 0,5 kg is available as an
option.
Cycle adjustments
Seat height should be adjusted to a comfortable
position. A suitable height is when your knee is
slightly bent and the middle of the foot is straight
above the pedal axle with the pedal is in its lo-
west position. To adjust the seat height loosen the
lever on the seat tube. See fig: Adjustments.
The handlebar setting shall give a comfortable
position when cycling. During longer exercise
sessions it is recommended to occasionally chan-
ge the handlebar position. To adjust the handle-
bar loosen the quick release lever. See fig: Adjust-
ments.
NOTE! The handlebar stem should be inserted
into the frame tube at least 3 inches (about 8 cm).
this measure is marked out on the stem(3).

Computer Instruction
The ergometer is equipped with a Fitness compu-
ter showing pedal revolutions per minute (RPM),
heart rate in bpm (HR), exercise time in minutes
and seconds (TIME), cycling speed in km per
hour or miles per hour (SPEED), covered distan-
ce in km or mile (DISTANCE). Furthermore the
workload (kp = weight basket + weights in kg)
can be set which gives a reading of burned calo-
ries (CAL) as well as power (WATT) on the com-
puter display. The energy is usually expressed in
kJ (kilo Joule) or cal (kilocalorie, kcal). One kcal
is aprox.4,2 kJ. The power is depending on the
pedaling speed which makes it possible to adjust
the workload/power by increasing or decreasing
the pedalling speed.
Press any button or move the pedal to turn on
the meter. At the display for heart rate (HR) a
♥ is lit which means that the meter is trying to
find a pulse signal from an external source (chest-
belt with electrodes, our part.no 9339-98). If the
meter can not find such a signal this HR func-
tion is automatically turned of after 30 seconds.
When the function is turned off the ♥symbol is
not lit any more. The heart rate function can be
turned on again by pressing a button.
Timer starts automatically when pedals are
moved. Meter values for Time, Distance and Ca-
lories can be set to zero by pressing the RESET
button for more than 2 seconds.
To get correct readings for calories and watts
the kp value on the electronic meter has to be
set to the same value as the workload that is the
weight of the basket including the weights in it.
Example: The workload is 3 kg (weight basket 1
kg + 2 x 1kg weight). Press the kp button to the
left on the meter. The lower display window is
now flashing and showing figures in kp. Increase
or decrease in steps of 0.1 kp by pressing the kp
button () or the RESET button () until the
reading is corresponding with the actual or de-
sired kp values (workload) from the weight bas-
ket. After that press the CAL/WATT button to
either show the CAL or WATT figures. The watt
reading on the display depends on the pedalling
speed. The watts can be adjusted accordingly by
increasing or decreasing the pedalling speed.
Km/Miles
Km and km/h is the default setting from the fac-
tory. If you want the settings to be in miles, take
the meter out of the panel. Turn off the meter
by taking out one battery. On the back side is
a switch with two settings - 1 and ON. See fig:
Batteries in section ”Batteries”. 1 is equal to km
and km/h and is the default setting. ON is equal
to mile and mph. Choose position and install the
battery again. Put the meter back again into the
panel.
Do not expose the fitness computer to direct
sunlight or extremely high temperature. Do not
use any dissolvents when cleaning. Use only dry
cloth.

Service action Time? Service interval
Keep your Ergometer clean and properly lubricated 5 min once per week
Periodically wipe the surface with a rust preventative, especially when it
has been cleaned and the surface is dry. This is done to protect the chrome
and zinc parts as well as the painted parts.
5 min 4 times per year
Check now and then that both pedals are firmly tightened. If not the th-
reading in the pedal arms will be damaged. Also check that pedal arms are
firmly tightened on the crank axle, tighten if necessary. When the Ergome-
ter is new it is important to tighten the pedals after 5 hours of pedaling.
5 min 4 times per year
Check that the pedal crank is secure to the crank axle. 5 min 4 times per year
Be sure that the pedals are moving smoothly, and that pedal axle is clear
of dirt and fibers.
5 min 4 times per year
When cleaning and lubricating be sure to check that all screws and nuts
are properly tightened.
10 min 2 times per year
Check that the chain is snug and there is no play in the pedal crank. 15 min 2 times per year
Check that pedals, chain and freewheel sprocket are lubricated. 5 min 2 times per year
Be sure that the brake belt does not show significant signs of wear. 15 min 2 times per year
Check that the handlebars and seat adjustment screws are lubricated. 5 min 2 times per year
Be sure that all moving parts as crank and flywheel are working normal
and that no abnormal play or sound excsists. I.e. play in bearings causes
fast wearing and with that follows a highly reduced lifetime.
Pay attention, if
any mislead or mal-
function.The faults
must be attend to
at once before any
further use of the
bike.
Check that the flywheel is placed in the center and with plane rotation.
Service check & maintenance
To keep your Ergometer in good shape you should make a regular service.

Batteries
The batteries are in a separate package at deli-
very. The batteries may need to be replaced upon
assembly. To replace the batteries at any time,
take the meter out of the housing by bending up
in the lower end with a coin or similar. The bat-
teries, 2 x 1.5V size AA(R6), which are placed in
the holder on the backside of the meter, can then
easily be changed. See fig: Batteries.
After the batteries has been replaced all segments
in the display are visible and a buzzer will sound
for two seconds. After 2 seconds the meter turns
to main display again and normal function. Put
the meter into the housing again.
Note: On the backside of the meter is a switch to
change meter function from km to mile or mile
to km(2).

Replacement of brake cord/belt
Remove the instrument cover by loosening the
screws on each side of the cover. Loosen the cord/
belt bracket, see fig: Brake device, and take away
the brake belt from the tension center. Loosen or
cut away the knot or tie up the knot at the other
end of the belt. After that take away the belt from
the bike. When assembling a new brake cord/
belt, first enter one end into the belt hole in the
tension center, see fig: Brake device, and make a
knot and let the knot fall into the bigger part of
the hole. Then assemble the new belt exactly as
the old one.
When replacing the brake belt it is recommen-
ded to clean the brake surface. See section ”Brake
belt contact surface”.

Adjusting the brake cord/belt tension
At first check that the brake belt is lying correctly
on the flywheel brake surface. See fig: Brake cord
and Brake device.
Put 4 kg in the weight basket(4). Rotate the fly-
wheel by hand. The basket shall now lift up so
the distance to the flywheel is at least 40 mm and
maximum 60 mm. If this is not the case the brake
belt has to be loosened or tightened a little at the
tension center. If the basket is too low, shorten
the belt somewhat. If the basket is too high, len-
ghten the cord somewhat.
Loosen the cord bracket(2) somewhat so that
the cord length can be adjusted. Turn the tension
center(3) approximately 45 degrees and after that
tighten the braket again. Release the basket and
check if the measurements above are OK when
the flywheel is rotated by hand. Repeat the above
if necessary.
Note: The basket gives the correct workload whe-
rever it hangs between the upper stop position and
the lower stop just above the ywheel. Note that the
tension center can’t get in contact with it’s upper or
lower stop. In that case you will not receive correct
brake level. The measurements above (40-60) gives
a good margin.
