☺ "Be Prepared."
Although it is usually possible to repair a damaged tube with a patch, a
patched tube may be weakened and may not hold the high pressure required
for Helio Cycle tires. Replace punctured tubes with new ones, and if you must
use a patch temporarily, replace a patched tube as soon as possible.
Here's what you'll need to repair a flat tire:
1. New inner-tube
2. 15 mm spanner (plus a 10mm spanner for the rear wheel)
3. Tire levers
4. Pump with pressure gauge
5. A support for your Helio Cycle while the wheel is off
Front tire puncture:
1. Place the support under the front chassis of the Helio Cycle so that it is
supported with the front wheel slightly off the ground.
2. Loosen the two front-wheel-retaining nuts.
Use only a proper fitting spanner to tighten or loosen the wheel nuts. Using
grips or a loosely fitting wrench will damage the wheel nuts.
3. Remove the front wheel.
4. Depress the tire valve to let all the air out of the tube.
5. Remove one side of the tire by gripping the tire with both hands and bending it
downward until one side of the tire peels off the rim. If this proves difficult, use
the tire levers to carefully pry the tire bead over the rim. It's not necessary to
remove the tire completely from the wheel. Removing one side is sufficient.
DO NOT use a screwdriver to pry the tire off the rim. If you do, you'll likely
damage the tube, rim, and/or the tire. You can buy inexpensive tire levers at
any bicycle shop.
6. Remove the inner-tube and inspect the inside of the tire for damage or sharp
objects protruding into the tube cavity.
7. Inflate the new tube just enough to give it some shape and replace the old
tube with the new one.
8. Start at the valve stem and work the tire bead back into place on the rim. If you
have trouble getting the tire seated over the rim, carefully use a tire lever to
pry it into place, making sure not to pinch the tube.
9. Inflate the tire to the proper pressure, checking to make sure it's properly
seated on the rim. (see page 35 for details on proper tire pressure).
10. Reinstall the wheel on the fork.
11. Retighten the wheel retaining nuts.
