IMPORTANT
In the unlikely
event of a brake line
snapping in ight, or
a handle becoming
detached, the glider
can be own by
gently pulling the rear
risers (D-risers) for
directional control.
WARNING
Never y with your
trimmers released in
turbulent conditions.

PREPARATION
07
IMPORTANT
Using the accelerator
or the trimmers
decreases the angle
of attack and makes
the wing more prone
to collapse, therefore
using the accelerator
or releasing the
trimmers near to the
ground or in turbulent
conditions should be
avoided.
Never apply the brakes
whilst using the speed
system - it makes the
wing more prone to
collapse.
It is recommended
to pilot the wing with
the rear risers during
accelerated ight.
Accelerator System
To set up the accelerator system, rst route the lines supplied with the speed system through the
harness.Makesurethisisdonecorrectlyandthatthelinespassthroughallofthepulleys(checkyour
harnessmanualforinstructions).Attachthespeedsystemlinestotheacceleratorsystemontherisers
withtheBrummelhooks.

IMPORTANT
Never take off with
a glider that is not
fully inated or if you
are not in control of
the pitch/roll of your
wing.
Launching
Your Zero 3will launch with either the forward or reverse technique. The wing shouldbe laid out in

IMPORTANT
Only ever initiate
spiral dives with
the trimmers set in
the slow position.
Spirals with open
trimmers increases the
likelihood of nuetrality
or instability.
IMPORTANT
Always be prepared
to pilot the wing out
of a spiral dive. Use
opposite weight shift
and apply enough
outside brake to
stop the wing from
spiralling.

IMPORTANT: Do NOT lay the wing
at on the ground before packing the
glider, this will cause abrasion damage
to the top surface as you pull the glider
towards the middle. ALWAYS pack from
a mushroom or lift the wing off the
ground when gathering the wing and
grouping the leading edge.
IMPORTANT: Do not fold the glider in the centre, you
will bend the plastics, instead pack the wing with a full
concertina method from tip to tip before packing into the
stuff sac.
