Operating Instruction
Operating Instruction
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 using the tension knob(2). A change
of brake force is showed in the window(1). See
g: Workload device.
Cycle adjustments
The pedalling unit can be moved forward or
backward and locked in a comfortable position.
To move the unit pull the catch(1) and place the
pedals at a suitable distance. Let go of the catch
and make sure that it locks ( a ”click sound”).
The back support can also be adjusted up and
down to a comfortable position by loosing the
knob(2). See fig: Adjustments.

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
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.

tightened to prevent it from falling off the fly-
wheel.

Replacement of brake belt
Remove the left or the right frame cover by undo-
ing the mounting screws (5pcs). Put the crank in
a backward position. Move the cover somewhat
out in the front end and then take it backwards to
remove it. Set the tension device in min position
(min load - only white). Loosen the brake belt a
little more if needed at the adjustment nut. See
fig: Brake belt. Remove the old brake belt from
the spring and tensioner. Attach the new brake
belt and assamble the bike in reverse order.
NOTE: When replaceing the brake belt it is re-
commended to clean the brake surface. See sec-
tion ”Brake belt contact surface”.
Fig: Brake belt contact surface
Brake belt contact surface
The brake belt should be regularly checked to en-
sure that it has not suffered excessive wear. If it
looks worn it should be replaced. Deposits of dirt
on the brake belt and on the contact surface may
cause the unit to operate unevenly and will also
wear down the brake belt. The brake belt contact
of the flywheel surface should then be ground off
with fine sand paper and any dust removed with
a clean dry cloth.
Dismantle cover and remove the brake belt/cord
according to section ”Replacement of brake belt”.
Grind with a fine sand paper. See fig: Brake belt
contact surface. Grinding is easier to perform if
a second individual cautiously and slowly pedals
the cycle.

Chain 1/2“ x 1/8“
It is strongly recommended to keep the chain
clean. Dirt build-up on the chain will cause ex-
cess wear. A chain lubricant and solvent for nor-
mal road bikes may be used.
Check the lubrication and tension of the chain in
regular intervals. In the middle of its free length
the chain should have a minimum play of 10 mm
(1/4in). See fig: Chain adjustments. When the play
in the chain is about 20 mm (3/4 inch) the chain
must be tightened otherwise it will cause abnor-
mal wear of the chin and chainwheels. Because of
this it is always recommended to keep the chain
play as little as possible. When the chain has be-
come so long that it can no longer be tightened
with the chain adjusters it is worn out and shall
be replaced with a new one.
Irregularities on the brake belt contact surface
are removed by means of a fine sand paper or an
abrasive cloth. Otherwise unnecessary wear on
the brake belt may occur and the unit can be-
come noisy.
Always keep the brake belt contact surface clean
and dry. No lubricant should be used. We recom-
mend to replacing the brake belt when cleaning
the contact surface. In regard to assembly and
adjustment of the brake belt, see ”Replacement
of brake cord/belt”.
