Press any key or move the pedal gives a signal to the meter that activates all functions.
At the display for heart rate (HR) a heart symbol is lit which means that the computer is trying to find a pulse signal from an external source (chestbelt with electrodes, Art. No: 9339-98 is delivered with the ergometer). If the meter cannot find such a signal the HR function is automatically turned off after 30 seconds. When the function is turned off the heart symbol is not lit any more. The heart rate function can be turned on again by pressing a key.
The timer starts automatically when pedals are moved. Meter values for Time, Distance and Calories can be set to zero by pressing the RESET button for more than two seconds. The watt reading in the display is depending on the pedalling speed. The watts can accordingly be adjusted by increasing or decreasing the pedalling speed. Calories are calculated all the time.

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.
We have chosen the following formula that we think complies with the results given for a standard cycle position.
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=0,2388×10-3 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.
891 E
To receive the correct value for calories and watts the workload (kp) has to be set on the display. Kp value correspond to the total weight in the weight basket (weight of the basket, including the weights in it).
Example: The workload is 2.1 kg (weight basket 0.1 kg + 2 x 1 kg weight). Press the kp key to the left on the meter. Down in the display window figures is now flashing (kp). Increase in step by 0.1 with kp button (up arrow) alt. the RESET button (down arrow) until the value is consistent with the weight basket, in this case 2.1. After that press the CAL/WATT button to either show the CAL or WATT figures. At further press on the CAL / WATT-button the display toggles between calories and watts.

891 E Wingate Option
To get correct readings for calories and watts the kp value on the electronic meter has to be set to the same value as the workload that is the weight of the basket including the weights in it. The rubber plates are included in the calibrated weight of the 1 kg weight basket.
Example: The workload is 3 kg / 6.6 lbs (weight basket 1 kg / 2.2 lbs + 2 x 1 kg / 1.1 lbs weight). Press the kp key to the left on the meter. Down in the display window figures is now flashing (kp). Increase in step by 0.1 with kp button (up arrow) alt. the RESET button (down arrow) until the value is consistent with the weight basket, in this case 3.0. After that press the CAL/WATT button to either show the CAL or WATT figures. At further press on the CAL / WATT-button the display toggles between calories and watts.
Do not expose the meter to direct sunlight or extremely high temperature. Do not use any dissolvent when cleaning. Use only dry cloth.

Heart rate 891 E and 891 E Wingate Option
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.
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 / 23 2/3″).
NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.

Work load control Monark 891 E
Monark Ergomedic 891 E is a test device, applied with a braking system, where the brake force can be adjusted with weights on a weight carrier. Weights are available in 0.1 kg / 2.2 lbs, 0.5 kg / 1.1 lbs and 1.0 kg / 0.2 lbs. This allows the brake load to be varied with 0.1 kg / 0.2 lbs. NOTE! 0,1 kg is the minimum weight, which is the weight of the weight carrier. The weight basket can also be set in its upper free/resting position and does then not give any work load at all. Disengage the basket by pushing the knob (1). See Fig: Adjustments.

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).

Settings
To adjust the height on the support stand pull the handle (2) outwards. Turn the handle clockwise to raise the stand and counterclockwise to lower it.

Work load control 891 E Wingate Option
Through pedalling the test person supplies kinetic energy to the flywheel. The flywheel is then braked by means of a brake belt/cord which runs around the flywheel. The workload is changed either by using other pedalling speed or by increasing or decreasing the tension of the brake belt/cord against the flywheel by place weights in the weight basket. Weights are available in 1 kg / 2.2 lbs, 0,5 kg / 1.1 lbs and 0,1 kg / 0.2 lbs. This makes it possible to vary the workload from 1 kp up to maximum 11 kp in steps of 0,1 kp. Braking power is expressed in kp where mass 1 kg / 2.2 lbs gives the braking force 1 kp.
NOTE! 1 kg /2.2 lbs is the lowest work load that can be set as this is the weight of the basket itself. A weight basket that only weighs 0,5 kg /1.1 lbs is available as an option. The weight basket can also be set in its upper free/resting position and does then not give any work load at all. The weight basket is released by pushing the release button(1), on the cover. See Fig: Workload adjustment.

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).

Settings
To adjust the height on the support stand pull the handle(2) outwards. Turn the handle clockwise to raise the stand and counterclockwise to lower it. See Fig:

**Adjustments.

Anaerobic tests 891 E Wingate Option
Model 894 E has a computer for anaerobic testing and makes the bike possible to connect to an external PC, PC-cable is included. A Windows application, included in the bike, makes it possible to make a lot of different type of anaerobic tests for ex. Wingate tests and so forth. The anaerobic tests can easily be set from 5 up to 300 seconds duration. For a closer explanation of the application look in the program manual, ”Monark Anaerobic Test Software User Manual”.
NOTE! To carry out anaerobic tests must cycle computer equipped with power from a wall outlet. Connect the supplied power adaptor into an appropriate wall outlet (230V). The circular connector on the secondary cable from the power adaptor is connected to the corresponding socket on the cycle under the instrument cover on the right side. PC cable is connected into the serial port underneath and to a serial port on an external PC. See Fig: Brake device. The LED’s on the top of the instrument panel indicates both that there is power to the unit and that the weight basket in its upper position / neutral. If the weight basket produces resistance it must be moved up in its upper locked position where it does not give any workload. Then the LED is lit – with a delay of about five seconds – indicating that the computer and cycle is in a ready position for a test.

Adjustment brake cord tension 891 E
At first check that the brake cord is lying correct on the flywheel surface, see Fig: Brake cord and Fig: Brake device Loosen the stop lever(2) from the tension centre(1). Put 1 kg in the weight basket(4). Rotate the flywheel by hand. The basket shall now lift up so the distance to the flywheel is at least 150 mm /5.9″ and maximum 190 mm / 7.5″. If this is not the case the brake belt has to be loosened or tightened a little at the tension centre. Lock the weight basket in its upper position with the stop(3) and after that loosen the lock washer(5) somewhat so that the cord length can be adjusted. If the basket is too low, shorten the belt somewhat. If the basket is too high, lengthen the cord somewhat. Tighten the bracket again and check that the distance between the weight basket and flywheel is between 150 and 190 mm when the flywheel is rotated by hand.
NOTE! To receive correct workload it is important to place the weight basket according to the description above. If the basket hangs too low it may touch the flywheel. If the basket is too high, wrong workload may obtains.

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.
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.
• Always keep the bike clean and well lubricated (once a 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 (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. Also check that 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 (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.

Batteries
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.
Alt. 1: 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.
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, 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.
Alt. 3: 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”.

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”.

Fig: 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 shall 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 a pair of tongs for dismantling spring. 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 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. Place the special remover (Art. No: 9100-14) in the adaptor and place the spacer and axle nut outside. See Fig: Special remover.
NOTE! Do not tighten the axle nut completely. It must be possible to loosen the sprocket-adaptor half a turn.
Replace sprocket-adaptor and assemble the new parts in reverse order according to the above.
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.
