Your new airgun is unique because it operates on either compressed air or CO
2
. To fill and shoot with CO
2
, an optional
CO
2
fill adapter must be purchased. This owner’s manual describes operating the gun with compressed air only. The
manual that comes with Crosman’s CO
2
adapter describes operation on CO
2
.
2. Operating the Safety
A. To Put the Airgun “ON SAFE:”
• Locate the safety directly in back of the trigger.
• Push the safety from the left side all the way in (Fig. 2). The safety is
not “ON SAFE” unless it is pushed all the way in and the RED ring
around the left side of the safety is NOT showing.
Like all mechanical devices, an airgun safety can fail. Even when the safety is
“ON SAFE”, you should continue to handle the airgun safely. NEVER point the
airgun at any person. NEVER point the airgun at anything you do not intend
to shoot
B. To Take the Airgun “OFF SAFE”:
• Push the safety from the right side all the way in.
• The airgun is ready to fire when “OFF SAFE.” When you can see the
RED line on the left side of the safety, the airgun is “OFF SAFE” and
can be fired.
3. Pressurizing and Depressurizing the Airgun
A. Pressurizing (Filling) the Airgun
[NOTE: Operation instructions for CO
2
operation are contained in the manual that comes with the CO
2
adapter]
WARNING:
Use only compressed air in this airgun. When using Crosman’s optional CO
2
adapter, you may use CO
2
. Use no other gasses, including oxygen, which can cause a re or
explosion that may result in serious injury or death.
• Be sure to wear eye protection
• Make sure the airgun is unloaded and not cocked. (See
step 4B. for instructions on uncocking and unloading.)
• Read all instructions with your high pressure hand
pump so you are familiar with its operation. Use only
a pump designed for filling a pre-charged airgun. Do
not use a standard “shop air” compressor as these
types of air compressors cannot produce the high
pressures required to operate the airgun.
• Put the airgun “ON SAFE” (see step 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 hand pump hose to the fill nipple (fig. 3).
• Make certain the bleed valve on the hand pump is fully closed (tighten in a clockwise
direction) (fig.4).
• Pressurize the airgun by pumping and continue until the gauge on the pump and the
gauge on the airgun are at 2,000 psi.
DO NOT fill the airgun to more than 2000 psi. See “Overfill” information below.
• Open the bleed screw on the pump base in a counter-clockwise direction to
bleed the hose.
• Disconnect the pump from the fill nipple.
• Place the cap over the fill nipple. Always keep the fill nipple capped to eliminate the
possibility of dirt entering the check valve.
Over Fill
• This airgun is designed for optimal performance at a pressure no greater than 2,000
psi. Over filling does not improve performance. It will actually lessen performance and
may cause the valve to lock. 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 2,000 psi.
• If the airgun will not discharge air with each shot the valve may be locked. In this case, contact Crosman
Customer Service at 1-800-724-7486.
WARNING:
Do not attempt to repair the airgun or to disassemble to correct an over ll
or valve lock. Parts can y from the airgun at dangerous speeds when it is disassembled while
pressurized.
B. Depressurizing the Airgun
• Keep the rifle pointed in a SAFE DIRECTION (see section 5A)
• Remove all the air from your rifle by repeatedly cocking and dry-firing with the rifle pointed in a SAFE DIRECTION
(see step 5A.) until the pressure gauge on your airgun shows no pressure on the gauge and air cannot be heard
when the gun is dry fired.
• Put the air gun “ON SAFE”.
• If the pressure in the gun cannot be relieved by using the dry firing process it may indicate a valve lock condition.
Contact Crosman customer service.
• Alternatively, a special tool (Crosman part number PCPDT1) is available that will de-pressurize the gun. Contact
Crosman customer service for information.
4. Cocking, Loading, Unloading and Uncocking the Airgun
WARNING:
Use .177 caliber pellets only in your .177 caliber Benjamin Discovery and .22
caliber pellets only in your .22 caliber Benjamin Discovery. Never reuse ammunition. Use of any
other ammunition can cause injury to you or damage to the airgun.
A. Cocking and Loading Pellets
• Put the airgun “ON SAFE.” (See Section 2A)
• Point the airgun in a SAFE DIRECTION.
• Be sure your airgun is properly pressurized (see section 3).
• Open the bolt by pushing the bolt handle up and pulling it all the way back until you hear two clicks.
• With the bolt in the rearward position, place one pellet, nose first, into the loading port
(breech) (fig. 6). This is a single shot pellet airgun. Load no more than one pellet
at a time.
• Lightly push the pellet into the barrel by closing the bolt and pushing the bolt handle
down to lock. DO NOT jam the bolt forward. This will damage your airgun.
• Be sure the bolt is closed and locked before firing. If it is not closed and fully locked,
the pellet may not be discharged.
B. Unloading Pellets and Uncocking Your Air Gun
Unloading
• The most common way to unload a pellet is to fire your airgun in a SAFE DIRECTION
following Section 5 on Aiming and Firing Safely. If a pellet has become lodged in the barrel follow the steps in
section 6 Removing a Jammed Pellet.
Un-cocking
• To uncock the action, take the airgun “OFF SAFE.” With the muzzle pointed in a SAFE DIRECTION, open the bolt
and pull all the way to the rear. Holding the bolt handle securely, pull the trigger with your other hand and slowly
ease the bolt as far forward as it will go with your hand. You may now lower the bolt and the airgun is un-cocked.
• Put the airgun “ON SAFE”.
5. Aiming and Firing Safely
A. Aiming the Airgun
• Always point your airgun in a SAFE DIRECTION.
• Follow the instructions for filling the air gun (section 3A) and loading pellets (section 4A).
• 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.
• The airgun is correctly aimed when the front sight blade is positioned exactly in the center of the notch of the rear
sight. The top of the front sight blade should be even with the top of the notch in the rear sight. The bulls-eye
should appear to rest on the top of the front sight.
• Before firing the airgun make certain there is sufficient pressure for proper operation. (see Figure 5).
B. Adjusting the sights
• The rear sight may be adjusted to shoot higher or lower (elevation). To move the point of impact up, turn the
elevation screw clockwise. To move the point of impact down, turn the elevation screw counter-clockwise.
• The rear sight may also be adjusted to shoot right or left (windage). Loosen the windage adjustment screw by
turning counterclockwise. Move the sight to the right to move the point of impact to the right. Move the sight
to the left to move the point of impact to the left. Tighten the windage adjustment screw by turning it clockwise.
6. Removing a Jammed Pellet
A jammed pellet is usually the result of trying to fire the airgun when the pressure is too low. Before firing the airgun make
certain there is sufficient pressure for proper operation. The gauge needle should be pointing to an area in the green zone
on the gauge (see Figure 5).
WARNING:
In this procedure you will put a cleaning rod down the barrel of a charged
airgun. It is extremely important that while you are doing this that the airgun be “ON SAFE”, the
bolt remain in open position and that your nger be kept away from the trigger. Always keep
the airgun pointed in a safe direction. Failure to follow this warning may result in serious injury
or death.
• Point the airgun in a SAFE DIRECTION.
• Put the airgun “ON SAFE”.
• Open the bolt by pushing the bolt handle up and pulling it all the way back until you hear two clicks.
• With the bolt in the rearward position insert a ramrod of the proper size into the barrel (start at the muzzle).
The barrel could be damaged if the proper sized cleaning rod is not used
NOTE: The bolt must be cocked and open for the jammed pellet to clear the breech when it is pushed out by the ram rod.
• Using the ramrod push the pellet into the pellet loading port (forward of the bolt), remove and discard the pellet.
Do not reuse that pellet.
• Point the airgun in a SAFE DIRECTION, close the action take “OFF SAFE” and fire. Put the airgun “ON SAFE”.
• If you are not able to unjam your airgun by following this procedure, take no further action. Crosman Corporation or
an Authorized Service Station will unjam your airgun. (no cost during the warranty period)
7. Maintaining Your Airgun
• Put one drop of Crosman silicone chamber oil (part number RMCOIL) on the O-ring on the nose of the bolt every
6 months or every 2,000 shots.
• DO NOT use petroleum-based lubricants with this airgun.
• Keep all petroleum-based lubricants away from the fill nipple. They MUST NOT be introduced into the high pressure
chamber. Use of petroleum-based lubricants in this area could result in an explosion resulting in personal injury.
• DO NOT MODIFY OR ALTER YOUR AIRGUN. Attempts to modify the airgun in any way inconsistent with this
manual may make your airgun unsafe to use, cause serious injury or death, and will void the warranty.
• If you drop your airgun, visually check to see that it works properly before you use it again. If anything seems
changed, like a shorter or weaker trigger pull, this may mean worn out or broken parts. Call Crosman customer
service for assistance before using your airgun again.
8. Reviewing Safety
• Never point the airgun at any person or at anything you do not intend to shoot.
• Always treat the airgun as though it is loaded and with the same respect you would a firearm.
• Always aim in a SAFE DIRECTION. Always keep the muzzle of the airgun pointed in a SAFE DIRECTION.
• Always keep the airgun on safe until you are ready to shoot.
• Always check to see if the airgun is “ON SAFE” and unloaded when getting it from another person or from storage.
• Always keep your finger off the trigger and out of the trigger guard until ready to shoot.
• You and others with you should always wear shooting glasses to protect your eyes.
• If your reading or prescription glasses are not safety glasses, make sure you wear shooting glasses over your
regular glasses.
• Use .177 caliber (4.5mm) pellets only in your .177 caliber Benjamin Discovery or use .22 caliber (5.5 mm) pellets
only in your .22 caliber Benjamin Discovery. Never reuse ammunition. Use of any other ammunition can cause
injury to you or damage to the airgun.
• 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.
• Place the backstop in a location that will be safe should the backstop fail.
• Your backstop should be checked for wear before and after each use. All backstops are subject to wear and will
eventually fail. Replace your backstop if the surface is worn or damaged or if a ricochet occurs.
• Do not attempt to disassemble or tamper with your airgun. Use an Authorized Service Station. Using unauthorized
repair centers or modifying the function of your airgun in any way may be unsafe and will void your warranty.
• Always keep your CrosBlock® trigger block in place when storing this airgun. Store the airgun in a secure location.
(See CrosBlock instructions packaged with this airgun for assistance)
• Before you store your airgun make sure it is not loaded or cocked. Store this airgun charged with compressed air or
CO
2
to keep the valves closed against dirt.
• Whenever you store the airgun, make sure it is “ON SAFE.”
