Operating Instruction

Workload device

When pedalling the subject stores energy in 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 using the tension knob(2). A change of brake force is showed in the window(1). See g: Workload device.

Cycle adjustments

The pedalling unit can be moved forward or backward and locked in a comfortable position. To move the unit pull the catch(1) and place the pedals at a suitable distance. Let go of the catch and make sure that it locks (a ”click sound”). The back support can also be adjusted up and down to a comfortable position by loosing the knob(2). See ﬁg: Adjustments.

Trouble shooting guide

Symptom Probable Cause/Corrective Action

The display is not working. Check that the batteries are OK.

No heart rate. Check the chestbelt (battery). Wet the thumbs and place them on the elec-

trodes. A low clicking sound will appear near battery lid while you click on the electrodes with one thumb. Use another external HR monitor to check the belt.

Check that the chestbelt is positioned correct on test person and tight enough. Check that the electrodes are wet, in hard cases it is necessary to use a contact gel or a mixture of water with a few drops of washing-up liquid.

The level for HR signal can vary from person to person. Put chestbelt on another known person who has a good pulse rendering.

Uneven heart rate. Use an external unit for example a pulse watch to check if it also indicates

irregular pulse. If it is the case there are probably disturbance in the room. Magnetic ﬁelds from high voltage cables, elevators, ﬂuorescent tube etc can cause the disturbance. Other electronic equipment could be placed to close.

If irregular pulse remains we recommend measuring HR manually. If HR still remains irregular at workload test person’s health need to be examined.

There is a click noise with every pedalling (increases with the weight).

The pedals are not tightly drawn, tighten them or change pedals. There is a loose in the crank cheek, tighten. There is a loose in the base bearing, contact your dealer for service.

Scratching noise is heard when pedalling. Check that the carriage block is taken off and that none of the covers is

scratching.

There is a click noise and a squeak noise when pedalling.

Untighten the chain a bit.

Service check & Maintenance

To keep your Ergometer in good shape you should make a regular service.

Service action:

If you wish to disinfect the surface of the bike we • recommend isopropyl alcohol. Use a damp but not wet cloth to clean the surface you wish to disinfect. Keep your Ergometer clean and properly lubricated • (once a week). Periodically wipe the surface with a rust preventa-• tive, especially when it has been cleaned and the surface is dry. This is done to protect the chromeand 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 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 (2 times per year). Check that the chain is snug and there is no play in • the pedal crank (2 times per 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 (2 times per year). Check that the handlebars and seat adjustment • screws are lubricated (2 times per year). Be sure that all moving parts as crank and ﬂywheel • are working normal and that no abnormal play or sound exists. I.e. play in bearings causes fast wearing and with that follows a highly reduced lifetime. Check that the ﬂywheel is placed in the centre 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 be changed.

Crank bearing

The crank bearing is long term greased and require 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.

Transport

At transport the brake belt should be somewhat 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 belt on pendulum bikes with motor, turn the power on and move the pendulum to 4 kp. Hold it there until 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 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 of the knot in the other end of the cord and then remove the hole 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 brake belt contact of the ﬂywheel surface should then be ground off with ﬁne sandpaper and any dust removed with a clean dry cloth.

Remove if there are any covers and loosen the tension on the brake belt. Grind with a ﬁne sandpaper. 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 sandpaper 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”.

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”.

Chain 1/2“ x 1/8“

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 in 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.

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 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 center line of the frame otherwise the chain and chain wheels makes a lot of noise and wears out rapidly.

Adjust chain adjusters to allow chain play according to above. Tighten hub nuts ﬁrmly. Put on frame covers again.

Freewheel sprocket

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 adapter and place the spacer and axle nut outside. See ﬁg: Special remover. Replace sprocket- adapter 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 adapter-sprocket half a turn.

The sprocket should be lubricated with a few drops of oil once a year. Tilt the cycle somewhat to make it easier for the oil to reach the ball bearing. See ﬁg:

Lubrication.
