CONGRATULATIONS ON YOUR NEW EXERCISE BIKE designed by Monark Exercise AB, Sweden. Monark has been the worlds leading manufacturer of high quality ergometers and exercise cycles for more than 40 years. GENERAL It is important that you keep your ergometer clean and properly lubricated. Most important is to protect the chromed and zinced parts but also painted parts benefit from the same protection. When cleaning and lubricating be sure to check that all screws and nuts are properly tightened.
PARTS BELOW ARE NOT ASSEMBLED. ASSEMBLY INSTRUCTION: See pages 6-9.
Serial number Fig. 1 Tip the cycle forward. Assemble the rear supporting tube with two bolts and two nuts. NOTE: Use the accompanying spanner. See fig 1. 6 Fig. 2 Tip the cycle backwards. Assemble the front supporting tube with two nuts onto the two fixed bolts. NOTE: Use the accompanying spanner. See fig 2.
Saddle bracket Fig. 3 Check that the inclination of the saddle is comfortable and that the sadle post bracket is firmly tightened. In order to change the inclination of the saddle, loosen the saddle bracket and tighten firmly again. Adjust to desired height position of saddle/saddle post by loosening the saddle post bolt. NOTE: Tighten firmly. See fig 3.
Before the handlebar stem is assembled be sure the expanding wedge is loose. Insert the handlebar stem into the frame tube and tighten the expanding bolt firmly by means of the lever. NOTE: The handlebar stem should be inserted into the frame tube at least 7.5 cm (about 3 inches). See fig. 4. Usually this measure is marked out. 7.5 cm To change the height of the handlebar, loosen the expanding bolt about 5 mm. Give the bolt a light push to release the expanding wedge.
Pedal marked R (Right) is to be assembled on the right hand side of the cycle (the chain wheel side). The pedal axle has a right hand thread and must be threaded onto the crank clockwise. Tighten firmly. See fig 6. L left Pedal marked L (Left) is to be assembled on the left hand side of the cycle. The pedal axle has a left hand thread and must be threaded onto the crank counter clockwise. Tighten firmly. See fig 5. NOTE! Check now and then that both pedals are still firmly tightened.
OPERATION INSTRUCTION The Monark Exercise Ergometer Model 828E is a test cycle which has an adjustable brake system where the brake force can be set/read in kilopond (kp) and Newton (N). The actual brake power is showed in Watts on the electronic meter.
The height of the saddle should be adjusted so that, when sitting comfortably with the middle of the foot above the pedal axle and with the pedal in its lowest position, the knee should only be slightly bent. The adjustment of the handlebar should give a comfortable ride. When cycling for a long time, it may be suitable some time during the exercise to change the position of the handlebar.

ELECTRONIC METER Press any button or move the pedal to turn on the meter. At the display for heart rate (HR) a © is lit which means that the meter is trying to find a pulse signal from an external source (chestbelt with electrodes, not included. Our part.no 9339-91). If the meter can not find such a signal this HR function is automatically turned off after 30 seconds. When the function is turned off the © symbol is not lit any more. The heart rate function can be turned on again by preessing a button.
REPLACEMENT OF BATTERIES Take the meter out of the housing by bending up in the lower end with something sharp. The batteries, 2 x 1.5V size AA(R6), which are placed in the holder on the backside of the meter, can then easily be changed. See fig.8. After the batteries has been replaced all segments in the display are visible and a buzzer will sound for two seconds. After 2 seconds the meter turns to main display again and normal function. Put the meter into the housing again.
ZERO ADJUSTMENT OF METER BOARD Remove the transport tape for the pendulum. Loosen tension device so the brake belt feels loos. Check that the pendulum will hang in vertical position. The index on the pendelum weigh shall now be aligned with the index at the 0-position on the board. Lock nut If adjustment is necessary, first loosen the lock nut and then change the position of the board, so that it will have its 0-index in line with the index of the weight. Tighten the lock nut after the adjustment.
CALIBRATION OF PENDULUM SCALE 1. Loosen the tension device so the brake belt feels loose. 2. Check 0-adjustment. See ZERO ADJUSTMENT page 15. 3. Detatch the front screw in the frame covers. 4. Fasten a known weight, e.g. 4 kg (our ref No. 9000-211) at the balancing spring. Note: The weight should not be less than 3 kg, due to the possibility of inferior accuracy. Take the left cover a little to the side so the weight cord hangs between the covers. See fig. 5.

REPLACEMENT OF BRAKE BELT Remove the tension lever. Dismantle the front cover over the pendelum weigh by detatching the 4 screws underneath. Remove the left or the right frame cover by undoing the mounting screws (5pcs). Put the crank in a backward position. Move the cover somewhat out in the front end and then take it backwards to remove it. Loosen the brake belt from the pendelum at the screw and lock washer. Take it apart at the spring and clip and remove it from the bike. See fig 11.
BRAKE BELT CONTACT SURFACE - BRAKE BELT The brake belt should be regularly checked to ensure that it has not suffered execessive wear. If it looks worn it should be replaced. 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 brake belt contact of the flywheel surface should then be ground off with a fine sand paper and any dust removed with a clean dry cloth. Dismantle cover see REPLACEMENT BRAKE BELT.
CHAIN ½ x 1/8 It is strongly recommended that a cahin solvent be used to keep the chain clean. Excess dirt built up on the chain will cause excess wear. A chain lubricant and solvent for normal road bikes may be uaed. 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 of 5 mm. See fig 12.

REPLACEMENT OF THE FREEWHEELING SPROCKET Remove left and right frame cover. See REPLACEMENT OF BRAKE BELT. Dismantle the chain as described on page 20 - 21. 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 (part No. 9100-14) in the adapter and place the spacer and axle nut outside. See fig 15. NOTE: Do not tighten the axle nut completely. It must be possible to loosen the adapter-sprocket half a turn.

CRANK BEARING The crank bearing is long term greased and needs normally no supplementary lubrication. If problem arises, please contact your Monark dealer. FLYWHEEL BEARING The bearings in the flywheel are lifetime greased and require normally no maintenance. If problem arises, please contact your Monark dealer.
THE IMPORTANCE OF REGULAR EXERCISE The human body is built for action not for rest. Once upon a time this was a necessity: the struggle for survival demanded good physical condition. But optimal function can only be achieved by regularly exposing the heart, circulation, muscles, tendons, skeleton and nervous system to some loading, i.e. training. In the old days the body got its exercise both in work and at leisure.
What kind of exercise to choose? 1. You should have fun when exercising. Choose something you find pleasure in doing regularly. 2. To get o good effect out of the training you should choose a form of exercise that engages large muscle groups. Then the demand of increased blood flow and oxygen transport will be so great that heart will increase its pump capacity. Jogging, calesthenics, aerobic dancing, bicycling, swimming, skiing and walking are excellent examples of exercises meeting this requirement.
DO I GET STRONGER? Cycling strengthens the muscles of the back, abdomen and legs. Daily chores become easier. Cycling also makes your heart stronger. Your pulse rate gets lower even when you exert yourself a little extra. Regular exercise also has a favourable influence on high blood pressures. HOW DO I TRAIN? 1. Warm up 3-5 minutes with a low pedal resistance. Pedal about 12 mph (20 km/h). 2. Increase the resistance until you feel the training somewhat hard. Keep the speed for 2-5 minutes.
