Tire Removal/Seating - Dynacraft MOUNTAIN BIKE Owner's Manual

WARNING:
Do not attempt chain repairs. If there is a
problem with the chain, have a bicycle service shop make any
repairs.
The chain must be at the correct tightness. If too tight, the
bicycle will be difficult to pedal. If too loose, the chain can
come off the sprockets. When the chain is at the correct
tightness, you can rotate the crank freely and you can pull
it no more than one-half inch away from a straightedge as
shown (see Figure 74).
Adjust the tightness of the chain as follows:
• Loosen the axle nuts of the rear wheel.
• Move the rear wheel forward or backward as necessary.
NOTE: Make sure the rear wheel is centered in the bicycle
frame (see Figure 75).
• Hold the wheel in this position and tighten the axle nuts.

TIRE REMOVAL/SEATING

Before adding air to any tire, make sure the edge of the tire
(the bead) is the same distance from the rim, all around the
rim, on both sides of the tire. If the tire does not appear to be
seated correctly, release air from the inner tube until you can
push the bead of the tire into the rim where necessary. Add
air slowly and stop frequently to check the tire seating and
the pressure, until you reach the correct inflation pressure
(see Figure 76).
