Tip the cycle backwards. Assemble the front suppor-
ting tube with two nuts onto the two fixed bolts. See
fig 5.
Note! Use the accompanying spanner.
Plastic tape
Take off the brake belt and remove the plastic tape from
the flywheel.

Note! It is very important that all of the plastic tape is
removed. Residue of the plastic tape may cause an uneven
operation.

The pedal marked R (right) to be assembled on the
right hand side of the cycle (the chain wheel side). The
pedal axle has a right hand thread and must be thread-
ed onto the crank clockwise. Tighten firmly. See fig 7.
The pedal marked L (left) to be assembled on the lefte

OPERATION INSTRUCTIONS
Exercise cycle 915E
This testing cycle is provided with a brake system, which
power can be read in watts at two different speeds, 24
km/h (60 rpm) and 28 km/h (70 rpm). See fig 8.
This model is also equipped with an electronic meter
which – on one big display – at the same time shows:
PULSE (heart rate), SPEED (km/h), TIMER, CALO-
RIES and DISTANCE (km). See more under Fitness
Computer.
When pedalling the test person supplies the flywheel
with a certain kinetic energy. This kinetic energy is
braked by means of a brake belt which runs around
the bigger part of the brake surface of the flywheel.
The brake power is changed either by using another
pedalling speed or by increasing or decreasing the ten-
sion of the brake belt against the flywheel by means of
the tension handwheel. See fig 8.
The height of the saddle is adjusted so that, when you
sit comfortably with your foot exactly above the pedal
axle and with the pedal in its down position, your knee
is only slightly bent.
The adjustment of the handlebar should give a com-
fortable ride. When cycling for a long time, it may be
suitable some time during the exercise to change the
position of the handlebar.

Keys and function
MODE key
Use ”MODE key to set mode and cycle through the
display windows as below:
PULSE HI – PULSE LOW – TIMER – CALORIES
– DISTANCE
SET key
Press ”SET” key to set desired value. If you hold/press
this key for two seconds or more, you can advance the
function value at a faster rate.
RESET key
A press on the key will clear the values separately for
TIME, DISTANCE, CALORIES (kcal) and HI/LOW
pulse limit individually.

OPERATION INSTRUCTIONS cont.
If you hold down the button for more than two se-
conds at normal display, all values except upper and
lower pulse limit will be set to zero at the same time.
PROGRAMMING EXERCISE TIME
Press ”Mode” key to advance to the time window, then
use ”SET” key to enter your desired time. Each press
of the SET key will advance time by one minute.
PROGRAMMING TARGET TRIP
Press ”MODE” key to advance to the distance win-
dow, then use ”SET” key to enter your desired target
trip distance. Each press of the SET will advance dis-
tance by 0.5 km.
PROGRAMMING CALORIES
Press ”MODE” key to advance to the calories window,
then use ”SET” key to enter your desired calories bur-
ned. Each press of the SET will advance calories by 10
Kcal.
PROGRAMMING HIGH AND LOW PULSE
RATE LIMIT
Press ”MODE” key to advance to the pulse window,
then use ”SET” key to enter your desired high and low
pulse rate/herat rate limit. Each press of the SET will
advance 5 bpm. If your heart rate is above the high
pulse limit you programmed, the computer will gene-
rate a beeping to warn you to stop exercise. In con-
trast, if your pulse rate is lower than your desired low
pulse rate limit, the buzzer will also beep to remind
you to continue your exercise.
PROGRAMMING TIMER
Use the MODE key to advance to the timer function.
Then use the SET key to adjust to desired time. Every
push on the SET key will increase the time by one
minute.
PROGRAMMING CALORIES
Use the MODE key to advance to the KCAL func-
tion. Then use the SET key to adjust to desired amount.
Every push on the key will increase the value by one
minute.
PROGRAMMING DISTANCE
Use the MODE key to advance to the DISTANCE
function. Then use the SET key to adjust to desired
distance. Every push on the key will increase the dis-
tance by one km.
NOTE:
When no key has been pressed for 5 seconds the dis-
play will return to normal. The computer starts auto-
matically when one of the keys is pressed or meter get
speed indication – is pedalled.
In normal display, please make sure the ❤-symbol ap-
pears on the display before measuring your pulse rate.
The ❤-symbol will automatically disappear to save po-
wer when no key has been pressed or no signal has
been received for 30 seconds or more. By pressing
”SET” or RESET” the symbol will turn on again.

SETTING OF WORK LOAD
If you intend to exercise with a work load of 50 watts
and a pedalling speed of 24 km/h (60 rpm), do as fol-
lows:
Check on the RPM-display of the meter that you have
achieved the correct pedalling speed.
After that the tension handwheel should be adjusted
so that 50 watts are shown on the scale for 24 km/h.
Power conversion table at other pedalling speeds
The conversion table below shows the conversion into
watts at other pedalling speeds than 24 and 28 km/h
respectively. The result is achieved according to the fol-
lowing example:
Chose as work load any of the watt numbers on the
scale for 24 km/h at the same time as you pedal with
this speed.
Let us imagine that you have chosen 120 watts as work
load. If you now increase the pedalling speed to 90
rpm the table should be read as follows:
Start from the line 24 km/h and continue to 120 watt
and further to the line for 90 rpm. You can then read
that the actual power is 180 watts. See the markings in
the table below.

CALIBRATION
Fig 12
Fig 11
Adjust the tension handwheel so that there is no ten-
sion in the brake belt.
Fasten a 4 kg weight (our part no 9000-211) around
the joint clamp. See fig 11.
When correctly set the weight – 4 kp – will be read on
the scale for watts – 60 rpm. See fig 12. Should there
be a deviation, dismantle the left cover. See page 12.
Adjust into the correct position by means of the adjus-
ting screw and locking nuts. See fig 11.
