Dynacraft MOUNTAIN BIKE Owner's Manual page 21

The stem should be pointing towards the
front of the bike, aligned with the front tire
(see Figure 18). Depending on the type of
bolt, tighten the stem bolt with either (B)
an adjustable wrench or (C) a 4, 5, or 6 mm
Allen wrench (see Figure 19).
If your bicycle comes with a threadless
stem (see Figure 20), we must first remove
the headset in order to install. Use (C) a 4,
5, or 6 mm Allen wrench to remove the pre-
load bolt, cap and cardboard spacer from
the headset. Discard the cardboard spacer
(see Figure 22).
Loosen the bolts on the side of the stem,
slide the stem into place, making sure it
lines up with the fork (see Figure 18). Check
the gap between the steerer tube and stem,
ensuring there is enough space to reinstall
the cap and bolt. (See Figure 21) If you need
it higher or lower, your local bike mechanic
can help you out with the adjustment. Snug
the pre-load bolt on top. Then tighten the
two bolts on the side of the stem, alternating
each bolt.
