Product Information

Serial number

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

Initial operation

LT2 is mechanically calibrated in the factory. The user may still want to check this. For the procedure, see section ‘Calibration’.

Apply power to the test bike by ﬁrst connecting the cable from the power adaptor to the test bike at the power connector (5) at the right side of the bike, see Fig: Overview. Then plug the power adaptor into the wall outlet.

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.

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.

LT2 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).

NOTE! Before you start using the bike - remember to remove any transport protection and protective tape on the ﬂywheel.

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 1 W=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.

Monark Exercise AB recommends that you make a mechanical calibration once a year to ensure the cycle’s accuracy.

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 respectively 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.

Fig: Saddle 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 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.

Fig: Placement of the chest belt

Fig: Electrodes on the back of the chest belt (1)

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

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 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.

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.

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.

The display returns to start view.

Press PLUS and PROGRAM for 5 seconds to set ‘User settings’.

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.

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. Make sure there are no loose cables. Use another HR receiver (HR watch or • test bike monitor) to check the chest belt.

Uneven heart rate Use an external unit, for example a HR watch, to check if it also indicates •

an irregular 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 (e.g. 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

Warranty

EU countries - Private use

If you are a consumer living in the EU you will have a minimum level of protection against defects in accordance with EC Directive 1999/44/EC. In short, the directive states that your Monark dealer will be liable for any defects, which existed at the time of delivery. In case of defects, you will be entitled to have the defect remedied within a reasonable time, free of charge, by repair or replacement.

EU countries - Professional use

Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period, Monark Exercise will repair or replace the product. Monark Exercise will not, however, refund costs for labour or shipping.

Other countries

Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period above, Monark Exercise will repair or replace (at its option) the product. Monark Exercise will not, however, refund costs for labour or shipping.

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

Warning

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.

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 belt / 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 axle 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 axle 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.

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 sprocket-adaptor 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.
