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: 9000212) 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 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 preventative, 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 center and
with plane rotation.
Monark 881 E
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. 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 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. 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.

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 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.
Fig: Chain adjustments
1) Chain adjuster
2) Hub nut
3) Chain play
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 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 sprocketadapter 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.
