The drive belt

Adjusting the drive belt tension
The drive system on your Helio Cycle is designed
to require very little maintenance. However, if one
of the two the drive belts become loose, the belt
may slip; making popping, snapping or clicking
sounds, and will need to be tightened. There are
two belts, the 'primary' is located inside the
chassis and the 'secondary' is visible on the rear
wheel gear. If you hear a popping sound during
acceleration or deceleration, stop as soon as
practical and follow the directions below. Ridding
with a loose belt will quickly lead to belt failure.
Increase tension on the secondary drive belt first.
If the problem persists, tension the primary belt.
Secondary Belt Tension Adjustment
1. Place a block of wood (or other support)
under the chassis so that the rear wheel is
slightly off the ground.
2. Slightly loosen the large rear wheel axle
nuts with the 15 mm wrench.
3. Turn the RIGHT belt tension adjuster nut clockwise one complete revolution
with the 10mm spanner. Then turn the LEFT tension adjuster nut clockwise
one complete revolution. Turning the belt tension adjuster nuts the same
number of revolutions will ensure that the wheel remains properly aligned in
the chassis.
4. Test the belt tension. If you can push it inward much more than ½ inch (1 cm)
with your thumb (using as much pressure as you would to affix a postage
stamp to an envelope) it's too loose. If the belt is too loose, continue to
