2. Operating the Safety
A. To Put the Airgun “ON SAFE:”

• Locate the safety on the right side of the airgun.

• Push the safety in and all the way forward toward the “S” for “ON SAFE” (Fig. 2). The safety

is not “ON SAFE” unless it is pushed all the way forward.

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 in and all the way backward toward the “F” for “OFF SAFE”.
• The airgun is ready to fire when “OFF SAFE”. When the safety is all the way back the airgun is “OFF SAFE” and can

be fired.

cartridges may explode at temperatures above 120°F (48.9°C). Do

not mutilate or incinerate them. Do not expose them to heat or store CO

2

cartridges at

temperatures above 120°F (48.9°C).

• Put the airgun “ON SAFE” (see Section 2A).
• Make sure the airgun is UNLOADED and POINTED IN A SAFE DIRECTION.
• Holding the airgun as shown, slide the grip plate straight back to open (Fig. 3).
• Turn the piercing knob left until it is all the way down.

force any CO

2

cartridge into or out of place. Do not store your airgun with a CO

2

cartridge in it. If you know you will not be using

your airgun for an extended period of time, empty the CO

to remember, as it will prolong the longevity of your airgun seals.

cartridge in it.

WARNING:

Keep hands away from escaping CO

2

gas. It can cause frostbite

if allowed to come in contact with skin. Always make sure the CO

2

cartridge is

empty before attempting to remove it from the airgun by slowly turning the knob

counter-clockwise all the way until you no longer hear the escape of CO

2

gas.

5. Aiming and Firing Safely

Always point your airgun in a SAFE DIRECTION.

Follow the instructions for inserting CO

2

(section 3A) and loading (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 BB may bounce off or ricochet and hit someone or
something you had not intended to hit.

Always choose your target carefully. For example, you may wish to shoot at paper bulls-eye targets that are attached
to a safe backstop such as the Crosman 850 Target Trap. A heavy blanket should be hung
behind the Target Trap 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 (Fig. 5).

When you are sure of your target and backstop, and the area around the target is clear,
take the airgun “OFF SAFE” (See Step 2B) and pull the trigger to fire.

6. Removing a Jammed BB
Follow the instructions for unloading BBs under section 4B. If you are not able to unjam your airgun by following the unloading pro-
cedure, take no further action. An Authorized Service Station will unjam your airgun at no cost during the warranty period.

7. Maintaining Your Airgun

Putting 1 drop of Crosman 0241 Pellgunoil

®

on the tip of every CO

2

cylinder will help to maintain your airgun. DO NOT

use petroleum distillate based oil or solvent and DO NOT over-oil as this can cause damage to your airgun.

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 ser-
vice 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 (4.5 mm) BBs only. Never reuse ammunition.

Do not shoot at hard surfaces or at the surface of water. The BB 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 even-
tually 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.

Before you store your airgun, make sure that it is unloaded, not charged, and that the airgun is “ON SAFE.”
