Octane Fitness Q45 Service Manual page 19

Issue
Resistance is too high (unit
is difficult to pedal on lowest
resistance setting).
Possible Cause
Arm pivot shaft collar nut is
too tight; pivot shafts should
feel solid, neither wobbly nor
too tight.
Drive belt tension is too high.
Belt tracking is off center.
What to Do

Loosen the two set screws on the collar
nut while holding the pivot shaft in place,
then re-tighten the set screws so that the
handlebars move freely but do not wobble.
The collar nut should be oriented so that
the set screws are positioned toward the
holes on the shaft (toward the middle
of the machine), as illustrated in Figure
2.10. (The white dot in Figure 2.10 is for
illustration only and does not appear on
the actual hex collar.)

With your fingers, twist the drive belt
between the belt tensioner and the drive
pulley; it should twist approximately 90º.

To loosen the belt, locate the double nut
setup on the adjuster rod (Figure 2.11).
Loosen the first one, back off the other one
full turn, then re-tighten the first. Recheck
the drive belt tension as above, making
sure that slippage does not occur between
the belt and the pulley while pedaling the
unit and when changing direction while
pedaling.

The drive belt should ride in the center, not
shifted to the right or left (Figure 2.12). If
it is off center, you may feel some added
resistance and will hear a rubbing or
swishing noise.

Inspect the belt tensioner (Figure 2.11).
If it is bent, causing the belt to be off
center, replace it following the directions in
Section III.
