B. Pressurizing (Filling) the Airgun with a High Pressure Tank
The Marauder may be filled from a high pressure tank (bottle). Scuba tanks and other high pressure tanks
can be outfitted for the task. Make certain that only clean, dry, compressed air is used in your filling
apparatus. A reputable dive shop or paintball shop is best suited to fill and service tanks and bottles used
for filling your PCP airgun.
Be sure to wear eye protection•
Make sure the airgun is unloaded and not cocked. •
(See section 6 for instructions on unloading and un-cocking.)
Read all instructions with your tank so you are familiar with its operation. •
Put the airgun “ON SAFE” (see section 2A).•
Point the airgun in a SAFE DIRECTION.•
Remove the cap that covers the fill nipple on the airgun.•
Connect the quick-disconnect fitting on the tank’s hose to the fill nipple (fig. 3).•
Slowly open the valve on your tank and start filling the gun SLOWLY. Filling too quickly will cause heat •
buildup that can affect accuracy of the fill pressure.
Watch the gauges on the airgun and your tank (if equipped) until the desired pressure is •
reached (2000-3000 psi)
DO NOT fill the airgun to more than 3000 psi. See “Overfill” information in section 3C.•
Turn the valve on your tank off when the desired fill pressure is reached.•
BLEED the fill hose COMPLETELY to avoid hose whip from pressure in the fill hose•
Disconnect the tank’s fill hose from the fill nipple on the airgun.•
Replace the cap over the fill nipple and tighten. Always keep the fill nipple capped to eliminate the pos-•
sibility of dirt entering the check valve.
TIP: If your airgun is being filled from completely empty (zero pressure) the tension of the hammer pressing
against the valve may keep the valve open which will cause air to leak down the barrel. This is most likely
to happen with a gun tuned for a high fill pressures, where the hammer spring preload is adjusted to a high
rate. In the event this occurs try cocking the bolt and leaving it in the rear (fully open) position to eliminate
the force on the valve allowing it to close. Always make certain the airgun is not loaded and there is not a
pellet in the chamber.
C. Overfill
Over filling beyond the “as tuned” best fill pressure does not improve performance. It will actually lessen •
performance and may cause the valve to lock. For instance a gun tuned for best performance at 2,000
psi may partially valve lock at 3000 psi. If you discover that the airgun has been over filled, try to dry fire
the airgun (cock and shoot with no pellet loaded) in a SAFE DIRECTION until pressure on your airgun
drops to 3,000 psi or less depending on where your gun’s tuned best fill pressure is.
If the airgun will not discharge air with each shot, the valve may be completely pressure locked and will •
require use of the degassing tool included with your airgun. Follow the instructions included with the
degassing tool to fully or partially depressurize the airgun.
4. Depressurizing the Airgun
Your Marauder airgun, like most PCP airguns, is best stored
with some pressure in the reservoir. This keeps the seals in the
airgun forced against the sealing surfaces. In the event you
want or need to depressurize (e.g. for service) follow the
following steps:
A. Dry Fire Method
Keep the air rifle pointed in a SAFE DIRECTION.)•
Remove all the air from your air rifle by repeatedly cocking •
and dry-firing with the air rifle pointed in a SAFE DIREC-
TION) until the pressure gauge on your airgun shows no
pressure and air cannot be heard when the shot is fired.
Put the air gun “ON SAFE”.•
B. Degassing Tool Method
Make certain the airgun is not in the cocked position by:•
o Pointing the airgun in a SAFE DIRECTION.
o Removing the clip.
o Closing the airgun bolt by sliding forward and latching.
o Pulling the trigger.
Insert the degassing tool included with your Marauder airgun •
into the threaded plug as shown in Figure 5A.
Turn the tool into the airgun in a clockwise direction until resistance is felt. This will indicate the nose of •
the tool has come in contact with the internal valve.
WARNING:
Performing the following procedure will exhaust air from the barrel at a high
rate. Make certain the airgun is pointed in a SAFE direction.
Using an Allen wrench or screwdriver through the hole in the degassing tool (fig 5B) apply leverage to •
turn the tool and force the internal valve open. This may require approximately 1-2 complete turns to
totally degas the airgun.
Remove the degassing tool completely from the airgun. Leaving the tool in the airgun will interfere with •
the normal operation of the firing mechanism.
5A
5B
Cock the airgun and dry-fire (no pellet) in a SAFE direction to make certain all pressure has been •
relieved from the airgun
Check the gauge to make certain all pressure has been relieved from the airgun.•
5. Loading the Airgun
WARNING:
Use .177 caliber pellets only in your Model BP1763 and .22 caliber pel-
lets only in your Model BP2263. Never reuse ammunition. Use of any other ammunition can
cause injury to you or damage to the airgun.
A. Loading the Clip
Lift the clear cover over the catch point and rotate in the •
direction of the arrows (clockwise) per Figure 6A. Turn
until the cover appears as shown in Figure 6B.
Place a finger under the clip covering the hole, place •
the first pellet in the clip, nose first (Fig. 6C). Make
certain the pellet does not protrude out the back of the
clip. In the event the pellet does protrude simply push
the pellet inward.
Rotate the cover counter clockwise and place the •
remaining pellets into the clip. Upon completion of filling
the remaining positions rotate the cover until it comes to
rest at the catch point as shown in figure 6D. The clip is
now ready for use.
B. Inserting the Clip
NOTE: Following these directions will result in your gun
being loaded and ready to fire.
Put the air rifle “ON SAFE” (see section 2A) and point in •
a SAFE DIRECTION.
Pull the bolt back to the cocked position.•
With the cover of the clip facing the butt of the air rifle insert •
the clip from the right side and push it inward until it snaps
into place. (fig 7)
Push the bolt forward fully and latch to chamber a pellet.•
The air rifle is now ready to fire.•
6. Un-Loading and Un-Cocking
A. Unloading- Removing the Clip
Put the air rifle “ON SAFE” (see section 2A) and point in a •
SAFE DIRECTION
Push the clip out of the receiver from the left side.•
Refill the clip and re-insert for continued shooting.•
B. Un-Cocking
In the event you are finished shooting, remove the clip as instructed and un-cock the air rifle by the
following steps:
Point the air rifle in a SAFE DIRECTION.•
Take the air rifle “OFF SAFE” (section 2B). •
Pull the bolt back to the rear position.•
While firmly holding the bolt in the rear position, pull the trigger.•
Continue to hold the trigger back while sliding the bolt forward to the latched position.•
Release the trigger.•
Put the air rifle on “ON SAFE” (see section 2A).•
The air rifle is now ready for storing.•
7. Aiming and Firing Safely
Always point your airgun in a SAFE DIRECTION. •
Follow the instructions for filling the air gun (sections 3A or 3B) and loading pellets (section 5A and 5B).•
You and others with you should always wear shooting glasses to protect your eyes. •
Do not shoot at hard surfaces or at the surface of water. The pellet may bounce off or ricochet and hit •
someone or something you had not intended to hit.
Always choose your target carefully. It is best to shoot at paper bull’s-eye targets which are attached to •
a safe backstop. A heavy blanket should be hung behind the backstop to prevent ricochet should you
miss the backstop.
Your airgun is designed for target shooting and is suited for both indoor and outdoor use. Always •
remember to place your target carefully. THINK about what you will hit if you miss the target.
Before firing the airgun make certain there is sufficient pressure for proper operation. The gauge needle •
should be pointing to the area between 1000 and 3000 psi on the gauge.
