Thank you for choosing a test cycle from Monark!

Ideal position is important for a performance to reach its maximum and increases the potential for a perfect performance. The new setting options, along with an upgraded workload adjustment, make Monark's renowned bike even better.

LC4 has a brand new frame that is adjustable in all directions• LC4's new frame also means the Q-factor can be reduced, which increases the opportunities for •

a better workout experience LC4 gives the condition, the rest is up to the rider• LC4 is also prepared for additional equipment - channels behind the covers make it easy to install •

different equipment for different needs LC4 is a great bike as it is, with additional equipment, it can be even better• LC4 can be calibrated, both mechanically and electronically•

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 LC4 the brake system and calibration have been updated so that it is safer and more accurate. LC4 has also a new and more powerful engine for faster workload control.

NOTE! Use of the product may involve considerable physical stress. It is therefore recommended that people who are not accustomed to cardiovascular exercise or who do not feel completely healthy, should consult a physician for advice.

Product Information

NOTE! Before you start using the bike - remember to remove the pendulum locking devices and protective tape on the ﬂywheel.

Serial number

The serial number is located on machine plate (4) according to Fig: Overview.

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.

LC4 is set to measure the workload at the ﬂywheel. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).

Initial operation

LC4 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 (14) at the right side of the bike, see Fig: Overview. Then plug the power adaptor into the wall outlet. Turn on the power switch (10) and a green LED (9) lights up.

The cable from the power adaptor can be locked with the clamp (15) which is placed below the power connection.

Perform the electrical calibration as speciﬁed in section ‘Calibration’. Test by pedalling the bike. If the bike is working properly, it is ready for use.

PC software

If you need a pc software to do exercise tests on the bike, our software is available for free download from our website: www.monarkexercise.se.

Calories

There have been different theories on how to calculate this, since it depends on several factors and this means that it can only be seen as an estimate.

As a standard calculation when we display calories on our calibrated bikes we use: 1 minute with 100W gives 7 kcal. It is easy to convert watts to calories if it was on the ﬂywheel, the formula is 1W=0,2388x10

-3

kcal/s with four decimals. But when you normally show calories you want to show the total amount of calories your body has used during your training, not only the calories "burnt" on the ﬂywheel.

We have chosen the formula given above that we think complies with the results given for a standard cycle position.

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: Saddle

adjustment.

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: Handlebar

adjustment.

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.

Validation

Fig: Saddle adjustment

Fig: Handlebar adjustment

The following procedure ensures that the bike works for daily use.

Check the HR function if you use chest belt, see • section, on 'Heart rate'.

Check the braking force by putting on a certain • workload and check that the load is applied.

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.

The user's heart rate can be measured with a chest belt that senses the electronic output of the heart. Chest belt ANT+ is supplied as standard.

Fuss-free HR measurement requires that the belt is correctly placed. Make sure that your skin is clean where the chest belt should be placed. When it is correctly ﬁtted the logo on the belt will be central and readable, outward and upright, by another person. The chest belt should be placed with a comfortable tension around the mid section of the chest, just below the breast muscle, see Fig: Placement chest belt. Moisten the electrodes before use, see Fig: Moistening

the electrodes.

NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.

Pulse standard (chest belts)

The following pulse standard / chest belts can be used:

Standard, uncoded 5K chest belts (5-5.6 kHz)• Chest belts with ANT+•

Short range ANT+: 0.6-0.8 m (24"-31 ½") Long range ANT+: 4-5 m (13-16 ft) Range 5K: 0.8 m (31 ½")

Pairing display and chest belt

Normally the display connects to the ﬁrst ANT+ chest belt in "short range" and shows the heart rate until the chest belt is outside the "long range". If there is no ANT+ chest belt but a 5K chest belt in "short range", the heart rate from the 5K chest belt is displayed until the signal is lost.

ANT+ is prioritized and the ﬁrst choice of the display. 5K is discriminated, but after 30 seconds with only 5K the display is locked to this chest belt as long as you do not lose the signal.

Pulse function

Monark Exercise AB recommend that you

use an ANT+ chest belt for best function.

(The display can be powered by batteries, 4x1.5V, R14, but only when you make the basic settings.)

If the values for rpm and watt start ﬂashing during use, the set workload requires higher brake power than 7 kp. To solve this, increase the rpm or decrease the set workload.

Cycle constant

The cycle constant is as default set to 1.00. Change using the (+/-) button.

When the cycle constant is set to 1.00 the power is measured at the ﬂywheel. This is used in Astrand test, YMCA etc.

When the cycle constant is set to 1.05 the power is measured at the crank. This is often used on electronically-braked bikes.

Metronome cadence

Metronome diodes show pedalling revolutions (rpm) relative to the set reference value. The metronome is located at the back of the meter. The default value is 60 and can be adjusted with (+/-) button. The green LED in the middle ﬂashes twice for each pedal revolution which helps to keep the right pedal cadence, see Fig: Display and Fig: Metronome.

The meter can be rotated so that the rider does not see the values in the display, but only sees the ﬂashing diodes (in order to keep the right pedal cadence).

If START STOP is pressed, or if no button is pressed for 20 seconds (in all steps), the changes are saved and the display returns to normal with the new settings active.

Calibration

Two short beeps are heard and the calibration is nished.

The bike is ready to use.

Check the potentiometer value at 0 kp

Zero the scale, see ‘Scale - Zero adjustment’ • Release the brake belt tension by lifting the •

pendulum over 0.5 kp (the motor starts). (The brake belt tension can also be loosened •

by running the engine manually. This is done by pressing (-) in the calibration mode.)

Move the pendulum to current value and hold it still until the potentiometer value stabilized

Press ENTER for next step

Repeat according to the pictures to the right

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 or if you adjusted the 0-index.

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.

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.

= Tightens brake belt

= Slackens brake belt

Manual motor control

By pressing the (+/-) button in the calibration mode, the motor can be run manually if rpm is less than

30. This is to ensure the functioning of the engine for service or support, and to release the brake belt tension.

Press START STOP and PROGRAM for 2 seconds to enter calibration mode.

To calibrate the bike, you must have a 4 kg calibration weight. This is available as an accessory.

If you have started the calibration mode

but change your mind, you can press the

START STOP button to exit without saving.

(However, if you press ENTER the calibration process has begun and must also be completed.)

NOTE!

Calibration can only be done from the display!

Calibration

All LC4 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 0.5 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.

During the test METS and l/min are continuously counted and displayed.

Calculation

METS values are displayed and calculated from the current workload. The two VO

values displayed during the test continuously calculate the average value for 5 seconds.

The formula used (values from ASTRAND original table) to calculate VO

2

at different workloads is:

0.2333 ... l / kpm = 0.01428 L / W (2.8 l / min at 1200 kpm)

This is according to Astrand's table between 150 W and 300 W, and a good approximation for 15-700 W and a cadence of about 50-65 rpm.

(Except LC4r)

The test is automatically stopped after six minutes if Steady State (SS) is active. If not, the test continues until SS is reached or the time reaches 12 minutes.

Steady State (SS) is checked by comparing the average HR during the period 4:45 to 5:00 with the average HR during the period 5:45 to 6:00. If the difference between these two average values is the same or less considered SS.

When the test is completed the results are calculated and shown directly in the display.

You can stop the test manually after six minutes by pressing START STOP even if SS is not active (an error message is shown). The result is calculated and displayed.

If the test is stopped because of the low rpm it starts automatically even if the rpm increases again.

About Increment test Increment is a testing protocol, where the power is

increased according to a predetermined schedule. An increment is used to see the HR increase in relation to the rising power. It is used in both submaximal to maximal tests to track the maximum capacity.

The test continues until the test manager or test person cancels the test.

penultimate step P2 = 15-second average HR at the end of the last

step PT = Target HR: 130, 150 or 170 beats / min

Formula for the WPT: WPT = W1 + (W2-W1)x(PT-P1)/(P2-P1) [W]

Relative WPT: WPT / kg = WPT / Weight [W / kg]

How it works

At the end of each step calculated average HR during the last 15 seconds, a beep sounds, 25 W or 50 W is applied workload, and a new countdown starts. In the ﬁrst ﬁve seconds of the next steps the display shows test time, workload and estimated average HR during the previous step. During these ﬁve seconds the values ﬂash.

This continues until the 15-second average HR is higher than the target HR (130 / 150 / 170). Then the test is stopped, a beep sounds, the workload reverts to start power, the ﬁnal 15 seconds of average HR is displayed. The text "COOL" is displayed and the sixminute countdown starts. A 15-second average HR is displayed after 1, 3 and 5 minutes of the countdown.

You can skip the "cool down" by pressing the START STOP and the results appear instantly.

Testing using LC4

The versatility of the LC4 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 chest belt for correct position. 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.

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 30 rpm. However, it is important to consider what each test documentation says about the pedal speed.

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 Astrand protocols estimate the maximum oxygen consumption, based on a submaximal workload while all others report the oxygen consumption required by the ﬁnal workload.

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.

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)

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).

Service

Note! Make sure the voltage indicated on the appliance corresponds to the local mains voltage before making connections.

Note that the text about service and maintenance is universal and that all parts may not be relevant to your bike.

LC4 / LC4r

32

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 (1) 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 (3) 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.
