Troubleshooting guide

Batteries
If the meter i sbattery-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.
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 cord 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
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 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.
Alt. 3: To loosen the belt on other bikes, turn off all
workload. 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 brake belt
contact of the flywheel surface should then be ground
off with fine sand paper 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”.
