cause and mark the location on the tire.
7. Remove the tire completely and inspect for a nail, glass, etc. and remove if
located. Also inspect the inside of the rim to ensure there are no protruding
spokes, rust or other potential causes. Replace the rim tape which covers the
spoke ends, if damaged.

toward the center of the rim. Start on either side of the valve and work around
the rim.

the tire.
14. Check that the tube is not caught between the rim and the tire bead at any point.
15. Using a hand pump, inflate the tube until the tire begins to take shape, and check
that the tire bead is evenly seated all the way around the rim. When properly
seated, fully inflate the tire to the pressure marked on the sidewall. Use a tire air
pressure gauge to check.

Hub Bearing Adjustment
When checked, the hub bearings of either wheel will require
adjustment if there is any more than slight side play.
1. Check to make sure neither locknut is loose.
2. To adjust, remove wheel from scooter and loosen the locknut on
one side of the hub while holding the bearing cone on the same
side with a flat open end wrench.
3. Rotate the adjusting cone as needed to eliminate free play.
4. Re-tighten the locknut while holding the adjusting cone in position.
5. Re-check that the wheel can turn freely without excessive side play.
How To Fix a Flat Tire
If you need to repair a tire, follow these steps:
1. Remove the wheel from the scooter.
2. Deflate the tire completely via the valve.
Loosen the tire bead by pushing it inward all the way around.
3. Press one side of the tire bead up over the edge of the rim.
Note: Use tire levers, not a screwdriver, otherwise you may
damage the rim.
4. Remove the tube, leaving the tire on the rim.
5. Locate the leaks and patch using a tube repair kit, carefully
following the instructions, or replace the tube.
Note: Ensure that the replacement tube size matches the size
stated on the tire sidewall and that the valve is the correct type
for your scooter.
