ongratulations, you are the proud owner of the finest
c
production crossbow in the world!
Please follow all safety, assembly and trouble shooting
instructions contained in this manual. It is extremely important
to read and follow the instructions before attempting to use your
crossbow. Serious injuries to yourself or others, damage to your
crossbow, or poor performance from your crossbow could result
from failure to thoroughly read and understand these
instructions. If any part of this manual is unc lear to you, contact
the Sales Department at 800-237-4507. After assembly of your
crossbow, please keep your manual for future reference.
For the Quad 400 Barnett highly recommends using a 22”
Carbon or Aluminum arrow with half moon nock weighing at least
450 total grains including a 125-grain practice tip or broadhead.
Depending on your state regulations, we recommend using
mechanical broadheads, which result in a more consistent flight
pattern.

Safety Guidelines
Quad-400
Barnett Quad-400 crossbows are equipped with an automatic
safety, which engages every time the crossbow is cocked. The
safety must be released before each shot. This, as with any
other mechanical device, does not guarantee total safety, as no
safety device is a substitute for common sense and safe
handling. The crossbow trigger is only to be pulled when the
safety is in "fire" position and NEVER when it is in the "safe"
position or anywhere between "safe" and "fire." Do not attempt
to alter or modify the safety or the trigger mechanism. When the
trigger is pulled before the safety is released, the safety may not
release. To correct this, push the trigger pull forward, then
release the safety catch.
The following rules should be followed at all times:
EXTREME CAUTION SHOULD BE USED AT ALL TIMES WHEN
HANDLING A CROSSBOW. FAILURE TO FOLLOW THESE
RULES COULD RESULT IN SERIOUS INJURY OR DEATH.
• Always keep your fingers below the flight track and
out of the path of cables and strings when firing the
crossbow.
• Never dry-fire the crossbow (shooting without an
arrow or too light of an arrow). Dry firing will void
the warranty and can result in damage to the limb
assembly and possibly cause personal injury.
• Never fire the crossbow until you are sure of your
target.
• Always use an adequate target and backstop when
target shooting.
• Always use suitable crossbow arrows, such as
Barnett's 22" 2216 Aluminum or Carbon arrows
with half moon nocks made by BARNETT for the
Quad-400. Arrows of improper stiffness or mass
weight may damage the limb and cable assembly,
voiding the warranty and possibly cause personal
injury.
• Always inspect the crossbow and arrows before
firing. Bent or damaged arrows are not safe to fire
and should be discarded or repaired.

**Please note: Peep sight is not included when a
crossbow package with scope is purchased.
1. Slide the rear peep sight onto the
attached dovetail with setscrew
facing the front of the bow.
2. Tighten setscrew when the peep is in
the proper eye relief position with
the hex key provided. See Figure 6
Fig. 6
Installing an Optional Scope
The recommended crossbow scope is a Barnett 4x32 mm fivereticle scope, which includes 1” rings to fit a 3/8” dovetail mount.
1.) Remove peep sight from the scope rail.
2.) Position your scope by moving it forward or backward
until the proper eye relief is found . This is typically three
to four inches from your eye to the eyepiece when you
are holding the crossbow in a shooting position.
3.) After the scope is installed you may remove the front
sight bracket and pins.
Important: Be sure to tighten scope mount rings before shooting
crossbow.

CROSSBOW OPERATION
Cocking your Crossbow
Be sure to apply Barnett lubewax to the center string
serving, cables and the flight track area from the string to
the trigger area.
1.) Place the foot stirrup on the ground with one foot in the
stirrup and the stock resting against your mid section.
See Figure 7
2.) Place both hands on the string at each side of the
crossbow body no more than ½ inch from crossbow body.
3.) Using even pressure pull the string back until it locks into
the trigger mechanism with an
audible “click”. Be sure to apply
downward pressure against
flight track.
4.) Slowly release hand
pressure on the string until you
are sure it is locked securely
into the trigger mechanism.
The crossbow is now cocked
with the safety on.
Note: The serving on the string has had a line on each side of
the flight surface marked at the factory. After cocking the
crossbow make sure that the marks on the string are showing
equally on each side of the trigger mechanism. Unevenly cocked
crossbows will have erratic arrow flight. When restringing your
crossbow mark the serving of the string, on each side of the
flight track at rest, where the string leaves the flight surface
(track) and apply Barnett Lubewax to the string serving and
track surface.
Arrow Retainer
When loaded, the arrow should lie “flat” in the f light grove. The
arrow retaining spring should not be twisted to the left or right
and should exert only enough pressure on the rear of the arrow
to hold it in place. It should not lift the front of the arrow off the
flight grove. At this point, the arrow should be ly ing directly
parallel with the flight grove. We recommend the use of Barnett
arrows manufactured specifically for your Barnett crossbow.
Fig. 7

Loading your Crossbow
1.) Place the arrow forward under the front sight bracket and lay the
arrow on the flight surface. When using arrows with half moon
nocks, be sure that the odd colored fletch is placed in the
flight grove and that the concaved nock is parallel to the
string.
2.) Slide the arrow back under the arrow retaining spring and
fully into the trigger mechanism. Note: The arrow
retaining spring should only exert enough pressure to
hold the arrow in place without lifting it from its position
on the flight surface.
Firing your Crossbow
To fire the arrow from your crossbow:
1.) Point the crossbow in a safe direction.
2.) Slide the safety forward to the off position. The crossbow
will now fire when the trigger is pulled. The safety MUST be
disengaged in this manner prior to every shot. BE SURE TO
KEEP YOUR FINGERS BELOW THE STOCK FORE END
(FLIGHT TRACK) WHILE SHOOTING. Note photos below
This will prevent your hands from being struck by the
string as it travels forward. The velocity of the string
hitting your fingers will cause severe injury.
Unloading your Crossbow
By far, the easiest way to un-cock a cocked crossbow is to fire an
arrow into a target or into the ground away from debris, loose
rocks or other people.

Sighting-In the Crossbow
Using the rear peep sight and front sight pins:
1.) Place the first sight pin near the top of the front sight
bracket.
2.) Shooting at a target from 10 yards, aim for the bulls eye. If
the first shot is above the bulls eye, move the pin up (or down if
the shot is below the bulls eye).
3.) If the first shot is to the left of the bulls eye, screw the pin to
the left (or right if the shot is to the right)
TIP: Move the pin in the direction of the error, follow the arrow.
Continue in this manner until you have three consecutive shots
into the bulls eye. Repeat this procedure with the other pin,
starting near the bottom of the sight bracket. It is
recommended that the bottom pin be sighted in to the 30- to 35yard range.
Arrow Selection and Proper Flight
Due to the unique design of your Barnett crossbow, it is
imperative that only specified arrows are used. These arrows
are correctly weighted to absorb the high energy generated by
the compound design. Lighter arrows simulate a “dryfire”
condition and will result in damage to the crossbow VOIDING t he
warranty. Barnett’s 22” 2216 Aluminum and Carbon arrows are
correctly “spined”. DRY FIRING WILL VOID THE WARRANTY.
• Use Barnett’s 22” 2216 Aluminum or Carbon arrows with
straight, offset or helical fletches with Half Moon Nock.
• Recommended fixed blade broadheads can be any threeblade low profile broadhead with a cutting diameter no
larger than 1-3/16”.
• When using fixed blade broadheads, the blades must be
aligned with the fletches of the arrow. This can be done
by placing a rubber o-ring between the broadhead and
the arrow front insert.
• Mechanical broadheads that simulate the flight of a field
point may be used where legal.
11
IMPORTANT DISCLAIMER
Because of the power of the Barnett Crossbow and the
inconsistent properties of wooden shafts, which have a tendency
to warp, vary in spine stiffness; density; moisture absorption, all
of which result in inaccuracy. Barnett International DOES NOT
RECOMMEND their use under any circumstance.
Possible injury could result from shaft breakage, ect., we accept
no responsibility or liability arising from the use of wooded shaft
arrows.
TROUBLESHOOTING
Arrow Flight
Possibly the greatest variable in accuracy are the arrows. These
differ greatly and have totally different flight characteristics.
Generally speaking, target arrows are more accurate than
hunting arrows. Because of the surface area of the fixed bladed
broadheads used in hunting there is a tendency for the arrow to
“plane”. To help overcome this we suggest that practice be made
well in advance of the hunting season with the type of arrows
you will be using to achieve consistent groupings. Consider the
following when selecting arrows; heavy, st iff spined arrows with
fletching hold more energy for humane harvesting at reasonable
ranges (15-35 yards). Lighter arrows are much faster however
hold less energy.
1. If the string has been changed was it a Barnett string?
2. Are the arrows straight and fletches (vanes) in good
condition?
3. Does the arrow lie flat (true) on the flight groove? Is the
arrow retainer to tight or twisted? (Adjust arrow retainer
with a pair of needle nose pliers – USE CAUTION)
4. Does the arrow slide smoothly and evenly into the trigger
mechanism?
5. When cocking your crossbow, are you pulling equally on
each side on each side of the string? (Mark your new
strings on each side of the flight track as stated earlier)
After cocking the crossbow, make sure the marks are
showing evenly on each side of the trigger mechanism.
6. When cocking your crossbow make a conscious effort to
hold the string on the flight track so as not to lift over the
arrow retainer.
7. Are you putting one fletching down in the flight groove?
12
8. When using broadheads, line up the blades with the
fletches on the arrow (using o-ring).
9. Have you checked the tiller to see
if any adjustments should be
made? Figure 8
**Tiller is the measurement between
the base of the limb and the
bowstring. The tiller measurement
tells you if both limbs are equally stressed. Your bow is in
proper tiller when this measurement is the same for both
limbs. Uneven tiller will cause erratic arrow flight. All
crossbows are accurately tillered at the factory prior to
shipping. To adjust the tiller, use an allen wrench and
measuring tape as shown in the illustration.
String Fraying
1. Are you using Barnett lubewax on the center string
serving and flight track every 5-10 shots and on the
cables when needed?
2. Keep the trigger mechanism and flight surface free of
obstruction.
3. Check for metal burrs on the flight track and arrow end
caps.
Limbs Weak or Losing Power
1. Has the crossbow been dry fired? (could cause limb to
crack).
2. Inspect the limbs for splits or cracks.
3. Are you using Barnett string (the proper length)?
Fig. 8
CARE AND MAINTENANCE
Care of String
The owners kit contains a tube of lube wax that should be
applied to the center serving and flight track every 5 – 10 shots.
Lube wax should also be applied anywhere the cables make
contact with the Teflon tape or flight track every 20 – 30 shots.
To extend the life of your cables it is important to apply
ARCHERY STRING WAX to all areas of the cables and string every
30 - 50 shots or when white fuzz begins to appear. If the
13
crossbow has been exposed to excessive moisture you may need
to apply wax sooner.
PRIOR TO EVERY SHOOTING SESSION, IT IS
RECOMMENDED THAT A COMPLETE CHECK OF CABLES,
WHEELS, SCREWS AND ARROWS BE MADE.
• Always store your crossbow in a safe, dry place.
• Do not expose your crossbow to extreme heat, such
as closed, hot vehicles or near heat sources.
• Inspect cables and strings for signs of wear. An
authorized service center or the factory should
replace Cables showing wear immediately.
• Periodically put a few drops of quality lightweight
machine oil in the trigger mechanism.
• Periodically lubricate the eccentric wheel axels with
lightweight machine oil.
• Keep the flight track and the string serving waxed,
reducing friction.
• Your prod can be left strung indefinitely although
we do not recommend that the bow be left in the
cocked position for periods longer than four hours.
With reasonable care of your equipment and diligent practice,
your crossbow will remain an accurate, highly efficient hunting
weapon.
