Inspect and tighten all parts of the exercise cycle reg-
ularly. Replace any worn parts immediately. 

The exercise cycle can be cleaned with a soft, damp
cloth. Avoid spilling liquid on the console. Keep the
console out of direct sunlight or the display may be
damaged. Remove the batteries when storing the
exercise cycle.

BATTERY REPLACEMENT

If the console does not function properly, the batteries
should be replaced. See assembly step 4 on page 5.
In addition, make sure that the console wire is
plugged into the console. 

HOW TO TIGHTEN THE CRANK

If the arms of
the crank
become
loose, they
should be
tightened in
order to pre-
vent exces-
sive wear.
Loosen the
crank nut on
the left arm of
the crank.
Place the end of a standard screwdriver in one of the
slots in the slotted crank nut. Lightly tap the screw-
driver with a hammer to turn the slotted crank nut
counterclockwise until the arms are no longer loose.

Do not overtighten the slotted crank nut.

When the

slotted crank nut is properly tightened, retighten the
crank nut.

HOW TO ADJUST THE RESISTANCE STRAP

If there is not enough pedaling resistance when the
resistance knob is turned to the highest setting, the
resistance strap may need to be adjusted. To adjust
the resistance
strap, first turn
the resistance
knob to the
lowest setting.
Next, locate
the slotted tab
on the front of
the exercise
cycle. Grip the
main part the
resistance
strap underneath the slotted tab and pull it towards
the slot. When a little slack is created, pull the end of
the resistance strap tight and then let go of the strap.
Turn the crank for a moment to make sure that there
is not too much resistance. 

HOW TO ADJUST THE CHAIN

The exercise cycle features a chain that must be kept
properly adjusted. If the chain causes excessive noise
or slips as you pedal, the chain should be adjusted.

To tighten the
chain, loosen,
but do not
remove, the
axle nuts on
both sides of
the flywheel.
Pull the fly-
wheel slightly
forwards.
Make sure that
the flywheel is
straight and tighten the axle nuts.
