Thank you for choosing a test cycle from Monark!
Ideal position is important for performance to reach its maximum. LC6/LC7 has a brand new frame that is adjustable in all directions. The frame also allows the Q-factor to be reduced, which further increases the possibilities for a perfect performance. The new setting options, along with an upgraded braking system, make Monark's renowned bike even better.
LC6/LC7 gives the conditions; the rest is up to the rider.
In today's society we are used to customizing our machines and tools for our own needs. The same applies to LC6/LC7. Through intelligent solutions parts can be customized according to user requirements. LC6/LC7 is also prepared for additional equipment, channels behind the covers make it easy to install different equipment for different needs. LC6/LC7 is a great bike as it is, with additional equipment, it can be even better.
Force is a strong word which brings many associations. For us, force is interesting when it can be measured and calibrated. For a brake-force to be correct, regardless of the system, it must be calibrated and controlled. On LC6/LC7 the brake system and calibration have been updated so that it is safer and more accurate. It is also quicker to adjust and has more options in that it is speed-independent, but can be switched into constant braking force as an alternative.
Monark has always been known for the bikes measurement accuracy, now it's even better.

Cycle adjustments
Seat height should be adjusted to a comfortable position. The appropriate height is to have the knee slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position. When adjusting the saddle height and vertical position, loosen the respective locking handles. See Fig: Overview at page 7.
The handlebar setting should be in a comfortable position when cycling. During longer exercise sessions it is recommended to occasionally change handlebar position. The handlebar can be adjusted both horizontally and vertically. This is done by loosening the respective locking handles. See Fig: Overview at page 7.
NOTE! Be sure that the stem and seat post are inserted to at least 100 mm in the frame. This is marked with “MAX” on the stem.
Initial operation
LC6 / LC7 is mechanically calibrated in the factory. The user may wish to verify this by performing the mechanical calibration of the pendulum weight. See ”Electronic calibration”.
Apply power to the test bike by first connecting the cable from the power adaptor to the test bike at the power connector (3) at the right side of the bike, see Fig: Front cover right. Then plug the power adaptor into the wall outlet. Turn on the power switch (2) and a green LED (1) lights up.
The cable from the power adaptor can be locked with the clamp (4) which is placed below the power connection.
Perform the electrical calibration as specified in section "Calibration Electronics”. Test by pedalling the bike. If the bike is working properly, it is ready for use.

Power on crank or ywheel
Monark bikes measure the effect of the flywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (measure the effect of the crankshaft, the difference is 4-5 %). These percentages will be primarily due to friction in the chain, pedals and bearings.
LC6 / LC7 is designed for fitness tests and is set for power measurements on the flywheel. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).

Measured quantities
The following units are normally used. Where multiple units are specified, the user can select, see the software documentation.
Control of the bike
LC6 / LC7 is built on a solid framework, a large well-balanced flywheel, a brake belt and a pendulum that measures the braking force. The pedals operate around the brake wheel via a chain, while a stretch mechanism tightens the brake belt to regulate the braking force to affect the flywheel. This brake force is given directly by the pendulum against the scale on the right side of the bike.
The computer system consists of a main unit (built in the bike) and a control unit (integrated computer on the bike, PC, terminal or other external equipment). The main unit reads pedal speed and braking force and to determine the test subject's heart rate by a chest belt, where applicable. In addition, the main unit activates an actuator, which adjusts the brake belt tension that regulates the braking force. This brake force is varied automatically in relation to changes in pedal speed, so that a constant power is maintained The bike is as default rpm-independent.
For information about how respective control units works, see respective sections.
The bike can be controlled externally by PC, terminal or other external equipment.
Here are instructions for connection and options for connection to external devices. If advanced technical documentation / data protocol for system builders or similar are required, contact Monark Exercise AB.
The control is performed over a serial line using ANSI/ ISO/ASCII format commands. Connector, a 9-pin D-Sub (male) located below the RPM meter, see Fig: Connector, is compatible with the RS232 standard.
The bike need not be switched off when connecting external components, but it is recommended to pre­vent transmission of incorrect data between devices over the connection.
Be careful when connecting different types of external equipment to prevent flash-over and subsequent injury. The user must ensure that the correct cables are used, otherwise you risk serious injury or equipment damage.

Checking the pulse function
This bike does not have a meter that shows the heart rate. However, the heart rate is displayed in the computer software or other external equipment.
While the patient rests, with the chest belt on, compare heart rate in the software with the manually taken pulse. If it does not correspond, check the chest belt contact area and moisten if necessary the electrode surfaces with water. Electrodes on the back of the chest belt. If this fails, call customer service.
The following procedure ensures that the bike works for daily use.
Check the pulse function, see section.• Check the brake force, see section.• Test by pedalling and check that a reasonable •
rpm is obtained - verify by a clock. Feel if the pedals move smoothly. Listen for unusual sounds. Remedy if necessary.
Adjust the handlebar and saddle and make sure • they are securely attached and that the adjustment is working properly.
Make sure the support legs are in position by • rocking the bike. Tighten if necessary.
If something unusual is found during the daily inspection that you cannot resolve, please call customer service.

Validation
Validation of force
Start the PC software (it is available for free download from our web site: www.monarkexercise.se) and select a test programme from the menu "Test". In the dialogue box that opens is a box showing the braking force in Newton, see Fig: Force and HR display. You do not have to press "Start" (1) to get the heart rate showed (2), but you must press "Start" to show the force (3).
With the pendulum pointer at 0, the display should 1. read "00N".
Move the pendulum pointer to 4 kp and the display 2. should now show "39N".
If the braking force is not displayed correctly, an electronic calibration must be done. See section "Calibration electronics".
NOTE! After this verification, the brake belt will be loose, which means that it takes about 15 seconds before the regulating device has tense the brake belt to normal again (5 N).

Zero adjustment of scale
Check that 0-index (3) on the scale (2) is in line with the pendulum pointer when the bike is at a stand still and the brake belt is loose. If not, an adjustment must be done. Loosen the screw and adjust the scale. Tighten the screw (1) after adjustment. See Fig: Adjustment scale.
Calibration
All LC6 / LC7 are calibrated in the factory, but a calibration of the pendulum can still be done to verify this. If so, please do the following.
Open the front cover. Check that the brake belt (3) is loose. If not, move the pendulum to 4 kp and hold it there a while to loosen it. Unhook the brake belt from the spring. Check that scale 0-index is in line with the pointer. Adjust if necessary, see section "Zero adjustment of scale".
Calibration weight 4 kg (Art. No: 9000-211) is hooked on the spring.
NOTE! The flywheel must be completely stopped before the weight is hung on!
This weight (4 kg) can, when properly adjusted, be read at the corresponding point on the scale. If there is a deviation, adjust the pointer to the correct position by adjusting the weight (2) inside the pendulum. To change the adjustment weight loosen the adjustment screw (1). If the pointer shows too low, the internal weight must be moved upwards. If the pointer shows too high, the adjustment weight is moved down. This process is repeated until pointer is in the correct position. Hook the brake belt in the spring and close the front cover.
Check the calibration of the pendulum weight once a year or when needed.

The following steps show how electronics are calibrated against the pendulum.
Open the front cover. 1. Check that the brake belt is loose on the flywheel, 2.
see Fig: Control loose brake belt. If not, move the pendulum pointer to 4 kp and hold it there for a few seconds. Move the pendulum pointer to 0 again, and check again that the brake belt is loose.
Adjust the scale, see "Zero adjustment of scale," 3. so that the pendulum pointer is pointing at the 0-index of the scale, see Fig: Zero position.
Turn off the power to the bike and move the 4. pendulum pointer to 4 kp, as shown in Fig: 4 kp.
Hold the pendulum pointer at 4 kp and turn the 5. power on the bike again and wait for a beep. Move the pendulum pointer to 0, see Fig: 0 kp. Wait for a beep.
Move the pendulum pointer to 2 kp, see 6. Fig: 2 kp. Wait for a beep.
Move the pendulum pointer to 4 kp, see 7. Fig: 4 kp. Wait for a beep.
Move the pendulum pointer to 6 kp, see 8. Fig: 6 kp. Wait for two beeps. Move the pendulum to 0 again.
The calibration is complete. Close the front cover.
Electronic calibration - with the pendulum
Calibration electronics
Usually it is not necessary to recalibrate the cycle electronically, but it should be done after each service, change of electronic part, movement, if you adjusted the 0-index, or after you have programmed the "Reset" by default settings.
The calibration coefficient calculated by the computer is stored in main memory. No matter when the power is turned on, the last stored calibration will be placed in main memory. New calibration automatically replaces the old.
A check of the electronic calibration can be done in the computer programme, see section "Validation of force".
NOTE! The pendulum must be kept still at the different positions. This is done by pressing down the pointer into the groove on the scale at each kp value.
Calibration
LC6 / LC7 has a mechanical brake and pendulum weight, making performance validation a simple procedure. Calibration is necessary so that the electronic and the mechanical parts of the cycle conform. The work carried out on the bike is a result of the braking force (pendulum mode) and the number of pedal revolutions (= distance). The effect is then counted out by dividing the work done by the time it took to accomplish it. Validation includes both mechanical and electronic procedures. For detailed information, see the computer programme's user manual. If the bike fails to pass any section of the validation, proceed to the calibration and/or service menu.
After any repair or service, a "Daily Check" should be done.
It is also possible to calibrate from the software. See the menu "Monark Ergomedic" - Check calibra­tion..." in the computer software.

Testing with LC6 / LC7
The versatility of the LC6 / LC7 enables it to be utilized in a variety of testing environments. The precision and reproducibility of the test values obtained with the bike, along with the uncomplicated way to set up the tests, means the bike can be used in clinical work tests, in occupational health services for the fitness tests as well as fitness centers, schools, sports clubs and the like.
In general, one should note that stresses on the tested person can become quite severe, whether in a clinical work test or a simple fitness test in physical activity contexts. As a precaution, it may be advisable, prior to beginning an exercise protocol, that each subject consults with a physician.
Before testing, the operator should review the entire protocol operation with the test person, explaining the work which will be required and the duration of the procedure. One should also agree on how the test person shall give signs of any fatigue, chest pain or other abnormal physical reactions.
The test person should not engage in heavy physical activity for several hours prior to testing to establish maximum oxygen consumption. In addition, all testing and exercise protocols should be performed a reasonable time after meals. The test person should also refrain from smoking within an hour of the testing period.
The tested person shall also have the appropriate clothing for a work test. Training suit or loose­fitting clothing is best. More detailed instructions are rarely needed, regarding the ride, but it may still be appropriate for the test leader to give some advice on pedalling, saddle height and position of the handlebars. It should be comfortable to ride. The appropriate height of the saddle is when the knee is slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position.
Let the test subject try to ride with low workload and see how it feels to hold a steady rpm.
Finally, the chest belt shall be put on, see Fig: Placement heart rate belt in section "Heart Rate (telemetry)" for correct placement. Check for a minute that a proper heart rate is displayed. The baseline heart rate may also be of assistance in determining the nervousness of the test subject. It may be appropriate to let the test person rest long enough before the test so a more or less stable resting heart rate can be read.
Power calculation
1 rpm = that a point on the flywheel moves 6 meters per minute.
50 rpm = 300 m 2 kp force makes 2 x 300 = 600 kpm/min
100 rpm= 600 m 1 kp force makes 1 x 600 = 600 kpm/min
Exact calculation: Watts = rpm x kp x 0.98065
"Rule of thumb" calculation: Watts = rpm x kp (2% error, but may be good enough in many cases)

Test person enforcement
The bike performs automated tests virtually by itself, requiring minimal intervention by the test operator. This allows the operator to pay careful attention to the test person without distraction. The response to the exercise protocol can be accurately estimated and appropriate action taken to assist the test person, if necessary. Some programmes have sections where the test person may develop significant physical activity. The effect on the test person should not be underestimated.
During the test it is important to observe the test person's appearance and heart rate. The testing should be stopped immediately if the test person reports chest pain, difficulty in breathing, etc. A system of prompt medical attention should be set up prior to testing, in case of emergency.
The test person may also have difficulty in keeping a steady pedalling speed. This is of minor importance (except in cases where the program assumes a constant braking force, since the effect is automatically adjusted to the correct value as long as the pedal speed is at least 35 revolutions / min (rpm)). However, it is important to consider what each test documentation says about the pedal speed.
Heart Rate (telemetry)
A person's heart rate can be measured with a chest belt that senses the electronic output of the heart. The chest belt is standard equipment.
The bike does not have a meter that shows the heart rate, however, the HR is displayed in the computer programme or in other externally connected devices.
Fuss-free HR measurement requires that the belt is correctly placed. When it is correctly fitted the logo on the belt will be central and readable, outward and upright, by another person. Before putting on the belt, clean the skin where the belt is to be placed. The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle, see Fig: Placement of the chest belt. Moisten the electrodes before use, see Fig: Electrodes on the back of the chest belt. To make contact with the HR receiver on the bike, the distance should not be more than 100 cm / 39 1/3". It is especially important when first used to identify the chest belt with the sensor, by standing close to get the HR (maximum 60 cm). This relates especially to the Polar heart rate belt.
NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.
In case of problems, turn off WiFi, Bluetooth and similar on computers nearby (including the display with integrated computer on LC7).

Reviewing results
The maximum oxygen uptake is a standard measure of the condition of the heart- and lung-functions. Dependent on the linear relationship between work and oxygen uptake and between work and heart rate, the heart rate response to work may be used to estimate the oxygen consumption. If the maximum heart rate is considered, the maximum oxygen consumption may be determined.
The YMCA and Åstrand protocols estimate the maximum oxygen consumption, based on a submaximal workload while all others report the oxygen consumption required by the final workload. The Bruce and Naughton protocols require that the test subject exercise at a workload level for a minimum of one minute to establish the oxygen consumption. If less than one minute is observed, the previous workload value is used.
The estimated maximum oxygen consumption derived from some of the ergometer tests is subject to the error of the “age related predicted maximum heart rate“. Although there is a definite and linear relationship between work and oxygen uptake, there are some differences in actual oxygen uptake based on individual work efficiency. Test persons who are less familiar with bike exercise and those individuals who are less fit, are more likely be less efficient than those who ride bikes frequently.
It should be noted that these results are estimates or predictions of maximal response and have a greater chance of being in error than if the individual were tested to their actual maximum value. Interpretation should therefore be made more carefully with an understanding of the possibility of errors in the methodology.
A relative fitness index can be obtained from the following tables:

on the electrodes, a low clicking sound will be heard at the battery cover, alterna­tively that the heart rate is displayed in the computer software. Make sure the belt fits correctly on the test person, see • Fig: Placement of chest belt in section "Heart Rate (telemetry)", and that the strap is sufficiently tightened. Moisten the electrodes, in severe cases it may be necessary to use gel alternative, one drop of dish washing liquid mixed in water. Pulse signal strength varies from person to person. Try the belt with a person known to have a good pulse wearing a chest belt. Check for loose cables or jack if you have a plug-in receiver. Use another HR re-• ceiver (HR watch or test bike monitor) to check the chest belt. Check that it is the correct receiver and that it is in the correct place. If it have a • round Polar logo, the logo should be readable.
Uneven heart rate Use an external unit, for example a HR watch, to check if it also indicates an ir-•
regular pulse. If this is the case, there is probably disturbance in the room. The disturbance may be electronic fields from power cables, elevators, lamps etc. or other electronic devices which are too close (eg. cell phones). Move the bike to a different location in the room or change rooms. If an irregular HR remains it should be checked manually. If the HR remains irregular at work the person's
health should be examined. No rpm reading Check cable.• Unable to calibrate force The potentiometer shaft is not attached to the pendulum shaft, tighten the screw. •

Operation interferences
It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences, i.e. at short over voltage. These interferences can often be caused by different machinery, which is started or stopped. The processor in the computer is then reacting incorrectly or is not working at all. The problems can be solved by means of a mains interference protector, which is connected between the wall outlet and the AC adaptor. .

Service check and Maintenance
It is important to carry out a regular service on your ergometer, to ensure it is kept in good condition.
Always keep the bike clean and well lubricated.
Service action:
We recommend isopropyl alcohol to disinfect the • surface of the bike. Use a damp but not wet cloth to clean the surface you wish to disinfect.
Surface treatment with a rust inhibitor, especially • when the bike is clean and the surfaces are dry This is done to protect the chrome and zinc parts as well as the painted parts (4 times per year).
Check now and then that both pedals are firmly • tightened. If not the threading in the pedal arms will be damaged. When the Ergometer is new it is important to tighten the pedals after 5 hours of pedalling (4 times per year).
Check that the pedal crank is secure to the crank • axle (4 times per year).
Be sure that the pedals are moving smoothly, and • that the pedal axle is clear of dirt and fibres (4 times per year).
When cleaning and lubricating be sure to check that • all screws and nuts are properly tightened (twice a year).
Check that the chain is snug and there is no play in • the pedal crank (twice a year).
Check that pedals, chain and freewheel sprocket are • lubricated (twice a year).
Be sure that the brake belt does not show significant • signs of wear (twice a year).
Check that the handlebars and seat adjustment • screws are lubricated (2 times per year).
Be sure that all moving parts, crank and flywheel • are working normally and that no abnormal play or sound exists. Play in bearings causes fast wearing and with that follows a highly reduced lifetime.
Check that the flywheel is placed in the center and • with plane rotation.
Grind the brake belt contact surface, see section • "Brake belt contact surface" (once a year).

If the meter is battery-operated, the batteries are in a separate package at delivery. If the storing time has been long the battery power can be too low to make the computer act correctly. Batteries must then be changed.
Flywheel bearing
The flywheel bearing is long-term greased and re­quires no supplementary lubrication. If a problem arises, please contact your Monark dealer.
Crank bearing
The crank bearing is greased and normally requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.
Transportation
During transport the brake cord should be tightened to prevent it from falling off the flywheel.
Replacement of brake belt
To replace the brake belt remove covers if necessary. Make sure that the belt is loose.
Pendulum bike with engine:
To loosen the brake belt on pendulum bikes with engine, connect power to the unit and raise the pendulum to 4 kp. Hold it there until brake belt is loose. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.
Weight basket bike: To loosen the brake cord on cycles with a weight
basket set the basket to its upper position. Loosen the lock washer that is holding the cord and remove it from the tension center. Loosen or cut off the knot on the other end of the cord and then remove the whole cord from the bike. When assembling a new brake cord, first enter one end into the hole in the tension center, and tie a knot and let the knot fall into the bigger part of the hole. Lock the end of the cord with the lock washer.
Brake belt contact surface
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 contact surface of the flywheel should be smoothed with fine sandpaper and any dust removed with a clean dry cloth.
Remove any potential covers and all workload on the brake belt and then remove it. Grind with a fine sand paper. Grinding is easier to perform if a second individual cautiously and carefully pedals the cycle.
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 become noisy.
Always keep the brake belt contact surface clean and dry. No lubricant should be used. We recommend replacing the brake belt when cleaning the contact surface. In regard to assembly and adjustment of the brake belt, see ”Replacement of brake belt”.
Manual pendulum bike / exercise bike:
To loosen the brake belt on the bike remove all tension. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.
NOTE! When replacing the brake belt it is recommended to clean the brake surface. See ”Brake belt contact surface”.

Chain 1/2“ x 1/8“
Check the lubrication and tension of the chain at regular intervals. In the middle of its free length the chain should have a minimum play (3) of 10 mm (1/4 inch). 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 abnormal wear of the chain and sprockets. Therefore it is always recommended to keep the chain play as small as possible. Loosen the hub nut (2) on both sides and tense the chain with the chain adjuster (1) when needed.
When the chain has become so long that it can no longer be tightened with the chain adjusters it is worn out and should be replaced with a new one.
To adjust or replace the chain, remove covers if required.
To adjust the chain the hub nuts (2) should be loosened. Loosening or tightening the nuts on the chain adjusters (1) will then move the hub and axle forward or backward. Then tighten the nuts on the hub axle again. See Fig: Chain adjustments.
To replace the chain, loosen the chain adjusters as much as possible. Dismantle the chain lock (6) and remove the chain. Use pliers to both release the lock washer and mount it again (4). Put on a new chain and assemble the chain lock. The spring of the chain lock should be assembled with the closed end in the movement direction (5) of the chain. See Fig: Chain replacement.
NOTE! At assembly the flywheel has to be parallell with the centerline of the frame. Otherwise the chain and sprockets make a lot of noise and wear out rapidly. kuggtoppar.
Then assemble the removed parts as above but in reverse order.

Freewheel sprocket
When replacing the freewheel sprocket remove frame covers if necessary. Remove the chain according to section ”Chain 1/2” x 1/8””.
Loosen the axle nuts and lift off the flywheel. Remove the axle nut, washer, chain adjuster and spacer on the freewheel side. Replace sprocket-adaptor and assemble the new parts in reverse order according to the above.
NOTE! Do not tighten the axle nut completely. It must be possible to loosen the adaptor-sprocket half a turn.
The sprocket should be lubricated with a few drops of oil once a year. Tilt the cycle to make it easier for the oil to reach the bearing. See Fig: Lubrication.
