Changing Tyres - Otto M1 Intro Bedienungsanleitung

8 Changing Tyres (Fig. 62-65)
Changing flat tyres requires only the necessary tools and minimal technical skills. Users may
change tyres themselves if they wish. We recommend carrying an emergency repair kit and tyre
pump at all times (if using pneumatic tyres).
Suitable tyre pumps are listed on the order form and are supplied with the product. Alternatively,
users can keep a spray can of hardening foam (available at bicycle shops) to fill a tyre in case
of punctures.
• In case of a flat tyre, carefully remove the tyre from the rim using the appropriate tools.
• Take care not to damage the rim or the inner tube.
• Repair the inner tube according to the directions in the repair kit, or, replace the damaged
inner tube with a new one.
• Before re-mounting the tyre, inspect the inner rim surface and the inside of the tyre for any
object that may have caused the puncture.
• Be sure that the rim bands are not damaged. They protect the tube from being damaged by
the ends of the spokes.
Mounting
• Place the protective rim band over the valve. Then push the valve through the rim. Screw on
the valve nut. The rim band can then be easily applied.
• Ensure that all spoke ends are covered.
Tyres
• Beginning behind the valve, place the lower side of the tyre over the edge of the wheel rim.
Pump the tube with a small amount of air until it assumes its round shape, and then insert it
into the tyre.
• Check to ensure the inner tube is properly positioned all around and is free of folds; if this
is not the case, release some of the air. Now you can easily install the upper side of the tyre
starting across from the valve, using both hands and working towards the valve.
