Product Information

Facts

Congratulations to your new Ergometer.

The Monark 928 Pro VO2 is designed to in a simple way be able to perform sub maximal ﬁtness tests and make calculations of the maximal cardiovascular capacity. The device can of course also be used for normal exercise. The ergometer has an adjustable brake system, which shows workload in watts at a pedalling speed of 60 pedal revolutions per minute.

The Monark 928 ProVO showing pedal revolutions per minute (RPM), heart rate in beats per minute (HR), exercise time in minutes and seconds (TIME), workload in watts (WORK LEVEL WATT) and calculated maximal oxygen uptake capacity in litres per minute (L/MIN) and in millilitres per minute and per kilo bodyweight (ML/ MIN/KG). For a complete directions for the computer please read the part ”Computer speciﬁcations”.

All 928 Ergometers are calibrated at the factory. This means that you can begin to use the ergometer directly after assembly. However, if the user wish to verify the scale calibration please read the instruction for “Calibration” in this manual.

Operating Instruction

Workload device

Through cycling supplies the test person kinetic energy to the ﬂywheel. This is braked by means of a brake belt which runs around the bigger part of the brake surface of the ﬂywheel. The workload is changed either by using another pedalling speed or by increasing or decreasing the tension of the brake belt against the ﬂywheel by means of the work load control knob. A change of the workload is done either by changing the pedal speed or by turning the tension knob, see ﬁg: Tension knob. Turning the knob clockwise will increase the workload and turning it counter clockwise will decrease the workload. The power level can be read on the big scale on the left side of the bike. At 60 RPM the workload level is from 0-250 watts.

Fig: Tension knob

Power measurement

The cycle is designed to measure the power on the ﬂywheel, because tests/protocols are made for it (for example Åstrand’s and YMCA).

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 to the bottom position. To adjust the seat height turn the quick release bolt(1) on the saddle post and pull until the saddle post is loose. See ﬁg: Adjustments.

The handlebar setting shall give a comfortable position when cycling. During longer exercise sessions it can be recommended to change handlebar position. To adjust the handlebar loosen the quick release lever(2). See ﬁg: Adjustments.

Computer Instructions

Press any button or turn the crank and the computer will be activated.

When pressing START/STOP the heart symbol will light up in the display for heart rate (HR), which means the computer tries to detect a pulse signal from an external wireless transmitter. This signal comes from a chestbelt with electrodes which is delivered with the bike. The electrodes on the belt shall be moistened a little before it is put on the chest. Moistening makes the signal good already from start. The chestbelt is to be placed just below the chest muscle. If the computer can not ﬁnd any signal this function for measuring is automatically turned off after 30 seconds. When this occur the heart symbol is turned off and time stops. This function can be reactivated by pressing START/ STOP again.

(rpm)

Time starts when START/STOP is pressed once. At next press on START/STOP all calculations are stopped. When pressing START/STOP after time is stopped, the time function is set to zero and started again. Calculations made on oxygen uptake (L/MIN and ML/MIN/KG) are stored in the display for three minutes after pressing STOP to ﬁnish the test. Also the ﬁnal HR is stored during this period. After three minutes all data is erased automatically.

LED-indicator bar for RPM

A pedal speed indicator bar is located on the upper side of the computer. If the display is put on in a forward direction the subject can see it to hold correct rpm.

HR-limits

Upper and lower HR-limits can be set for exercise.

HR alarm function

A sound alarm can be turned on or off. The alarm is turned on /off by, at the same time, pressing the keys (+) and (-). When function is turned on a repeated alarm sounds when exceeding the upper or the lower limit.

The computer can be used in two different ways

1. For automatic HR detection and calculation of maximal oxygen uptake.

2. For manual setting of HR and workload after which a calculation of the maximal oxygen uptake is made. The computer always has a default setting for automatic calculation when it is turned on.

Let the subject begin pedalling at 60 rpm. Set workload to correct level by turning the tension device near the handlebar and check the workload reading on the big scale behind the left pedal. Press (+) on the computer and adjust by (+) or (-) to the same reading as on the scale. When work level stops ﬂashing press START/STOP and the test starts.

Let the subject pedal for six minutes and then stop test if the HR reading has reached steady state. The test result is then stored in the display for 3 minutes.

Manual Mode

Press MODE and hold for two seconds. Indication ”MANUAL” will appear in the upper left corner in the display.

When the computer is set to Manual mode it can be used as a calculator for calculating oxygen uptake when the ﬁnal HR and workload are known ﬁgures. See example below.

Auto Mode (default)

Take the chestbelt and moisten the electrodes a little. Put on the transmitter belt just below the chest muscle and adjust to a comfortable feeling. The logo on the belt shall face straight forward. Press START/STOP on the computer. The heart symbol is lit in the display and the HR is displayed in a few seconds. Check that HR reading is steady.

After that make personal settings. Adjustment of ﬁgures can only be made when numbers are ﬂashing.

EXAMPLE:

Press (+) and then MODE. The upper HR limit is • ﬂashing and can be adjusted by (+) or (-). Press MODE again. The computer changes to • lower HR limit. Adjust by (+) or (-). Press MODE again and computer shows “SEX” • symbol. Adjust by (+) or (-) if needed. Press MODE and the computer shows “AGE” • ﬂashing. Adjust by (+) or (-) if needed. Press MODE, and (Kg) is ﬂashing. Adjust to lb if • preferred. If weight is set in kg just press MODE again and increase or decrease with (+) or (-) to correct ﬁgure.

EXAMPLE:

Press (+), (WORK LEVEL) begins to ﬂash.• Press (+) or (-) , to adjust work level.• Press MODE, the heart symbol lights up and • heart rate (HR) numbers begins to ﬂash. Adjust by pressing (+) or (-) until correct HR-ﬁgure shows. Press MODE again and symbol for sex begins to • ﬂash. Press (+) or (-) for adjustment. Press MODE and adjust age (AGE) by pressing • (+) or (-). Press MODE and (KG) ﬂashes.• Press MODE again if no change is to be done for • input of weight in pounds. Adjust the weight in kg by (+) or (-) and wait until the display stops ﬂashing.

The calculated maximal oxygen uptake in LITER/ MINUT and MILLILITER/MINUT/KILO bodyweight can now be read in the display.

Maintenance

Do not expose the computer to direct sunlight or extremely high temperatures. Do not use solvents when cleaning, just a dry cloth.

Personal settings are now ﬁnished and the computer will turn to normal display after ﬁve seconds.

Scale - zero adjustment

Calibration

Loosen possible tension in the brake belt by turning the knob at the handlebar counter clockwise as far as possible. Check that the moving pointer is aligned with the 0-index on the scale. If adjustment is needed, ﬁrst loosen the locknut(1) and then change the position of the scale board, so that it will have its 0-index in line with the moving pointer. Tighten the locknut after the adjustment.

1

Although all Ergometers are calibrated at the factory the user may wish to verify this by performing a mechanical scale calibration. If so please do according to the following.

Loosen possible tension in the brake belt by turning the tension devise (knob) at the handlebar counter clockwise as far as possible. Check that the scale 0-index is in line with the pointer(1). See ﬁg: Calibration. If adjustment is needed adjust according ”Scale -zero adjustment”.

A known weight(4), preferably 4 kg (Art. No: 9000-

211), is attached at(5). See ﬁg: Calibration. The pointer shall at correct calibration point at the calibration index(6) slightly above 225 watts.

If there is a deviation, adjust the pointer to correct position by the adjustment weight inside the pendulum(2). To do this the left cover has to be removed. To adjust the position of the adjustment weight the locking screw in the centre of the pendulum(3) must be loosened. If the pointer shows too low the internal weight must be moved upwards somewhat. If the pointer shows too high the adjustment weight is moved down a little. This procedure is repeated until pointer is in the correct position.

It is important to carry out a regular service on your ergometer, to ensure it is kept in good condition.

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. Clean and lubricate your Ergometer weekly. • 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 (4 times per year). Check that pedals are ﬁrmly tightened. If not, the • threading in the pedal arms will be damaged. Also check that the pedal arms are ﬁrmly tightened on the crank axle, tighten if necessary. 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 (2 times per 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 (twice a year). Be sure that all moving parts, 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. Check that the ﬂywheel is placed in the center and • with plane rotation.

Batteries

Monark 928 E Pro VO

13

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 be changed.

Crank bearing

The crank bearing is greased and normally requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.

Flywheel bearing

The bearings in the ﬂywheel are greased and do not normally require maintenance. If a problem arises, please contact your Monark dealer.

Transport

At transport the brake belt should be tightened to prevent it from falling off the ﬂywheel.

Replacement of brake belt

Alt. 3: To loosen the belt on other bikes remove all possible tension. Observe how the belt is connected. Take it apart and 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”.

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 covers and loosen the tension on the brake belt. Smoothe with ﬁne sandpaper. This 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 sandpaper or an abrasive cloth. Otherwise unnecessary wear on the brake belt may occur and the unit can become noisy.

To replace the brake belt remove covers if necessary. Make sure that the belt is loose.

Alt. 1: To loosen the belt on pendulum bikes with a motor, turn the power on and move the pendulum to 4 kp. Hold it there until the brake belt is loose. Observe how the belt is connected. Take it apart and remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.

Alt. 2: 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, 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.

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”.

It is strongly recommended to keep the chain clean. Dirt build-up on the chain will cause excess wear. A chain lubricant and solvent for normal road bikes may be used.

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) it must be tightened otherwise it will cause abnormal wear of the chain and chainwheels. Because of this it is always recommended to keep the chain play as little as possible. Loosen the hub nut(2) on both sides and tense the chain with the chain adjuster(1) when needed.

2

3

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 frame covers if necessary.

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. Adjust according to above recommendation. Then tighten the nuts on the hub axle again. See ﬁg: Chain adjustments.

To replace the chain, loosen the chain adjuster as much as possible. Dismantle the chain lock(6) and remove the chain. 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. Use a pair of tongs for dismantling and assembling the spring(4). See ﬁg: Chain replacement.

NOTE: At assembly, the ﬂywheel has to be parallel with the centerline of the frame otherwise the chain and chain wheels make a lot of noise and wear out rapidly.

When replacing the freewheel sprocket remove frame covers if necessary. Dismantle the chain as described in part ”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. Place the special remover (Art. No: 9100-14) in the adaptor and place the spacer and axle nut outside. See ﬁg: Special remover. 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.
