Operating Instruction

Workload device

The Monark Rehab Trainer model 881 E is an arm

and leg ergometer provided with a brake belt. The

power can be read in watts at 50 pedal rpm moreover,

the work can be read in kilo pond metres (kpm). The

Rehab Trainer is also equipped with an electronic

meter, showing pedal revolutions per minute (RPM),

the total pedal revolutions (TOTAL COUNT) and

time (TIME) function.

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.

Calibration

Calibration is done at the factory. If you for some

reason want to check the calibration, do as follows:

Tighten the brake belt through turning the control

knob so that pointer goes up to about 25-50 Watt at

rotation of the crank. Put the Rehab Trainer at the

edge of a table. Loosen the screws for the clamping

plate(3), so that the end of the belt is loose. See ﬁg:

Calibration. Fasten a 2 kg weight (Art. No: 9000-

212) to the brake belt(2). This weight should now be

read on the scale at 2 kp. See ﬁg: Watt scale.

Should there be a deviation between the position of

the pointer and the 2 kp marked on the scale, adjust

the loading spring by turning the adjusting screw until

the correct position is obtained. See ﬁg: Calibration

and ﬁg: Watt scale. Turn clockwise if the pointer is

placed too high and turn counter clockwise if the

pointer is placed too low. Remove the weight and

fasten the brake belt with the screw for the clamping

plate so that the pointer does not go below the zero

(“0”) marked on the scale.

The height level of the cranks is adjustable when

loosen the nuts, see ﬁg: Adjustments. Set the crank

arms at the desired position and fasten with the nuts.

If the cranks are not in line, adjust these. First set the

left hand crank straight upwards. Then loosen the

right hand crank by undoing the crank arm screw(6).

Adjust the position of the right hand crank so it is in

line with left hand crank and tighten the screw.

Service

Warning

Make sure the voltage indicated on the appliance

corresponds to the local mains voltage before making

connections.

Service check & 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.

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

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

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.

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.

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”.

Fig: Brake belt contact surface

Monark 881 E 11

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 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.

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.

Adjust chain adjusters to allow chain play according

to above. Tighten hub nuts ﬁrmly. Replace frame

covers.

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 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.
