How to Use: Byrna Self-Defense Launchers EP, SD AND LE User Manual

byrna Self-Defense Launchers EP and LE 

Introduction

The byrna Self-Defense Launchers EP and LE represent a cutting-edge line of non-lethal personal protection devices designed for effective self-defense in various scenarios. These launchers utilize compressed air (CO2) technology to fire .61 or .68-caliber chemical and kinetic projectiles capable of disabling threats without causing permanent harm. Ideal for civilians, law enforcement, and security professionals seeking a powerful but less-lethal alternative to firearms, these launchers enable users to protect themselves safely and legally.

Key benefits include rapid deployment with patented Pull-Pierce technology, an effective range of up to 60 feet, and versatility in ammunition—allowing for kinetic impact rounds or chemical irritants like pepper or tear gas. The ergonomic designs cater to both right- and left-handed users and prioritize ease of use, even under stress. Price ranges vary by model, with the SD model around $379, the LE model approximately $479, and the EP model positioned competitively within the lineup, making them accessible options for those committed to non-lethal defense. Available online with direct shipping and no required permits, these launchers provide peace of mind where traditional firearms may be impractical or legally restricted.

  While holding your hand over the top opening of the magazine to receive the exiting projectile, gently pull down on the projectile retainer bar.

INSTALLING THE MAGAZINE

1. Make sure the breech indicator is down and the breech is empty (Refer to “BREECH INDICATOR” on page 16).
2. Align the top of the magazine with the magazine well, and make sure the CO2 cap tool is facing the rear of the launcher.
3.  Insert the magazine into the magazine well of the launcher, pushing upward until you hear a click and the magazine locks in place.

REMOVING THE MAGAZINE

1. Always keep the barrel pointed in a safe direction when removing the magazine.
2. Put the launcher in SAFE mode.
3. Position your hand under the magazine to stop the magazine from dropping when it exits the launcher.
4. Firmly depress the magazine release button.
5. Remove the magazine.
6. Make sure there is no a projectile in the breech. If the breech indicator is in the raised position, press the breech indicator down to clear the breech (refer to “HOW TO CLEAR A LOADED BREECH” on page 17).

MAINTENANCE

Basic maintenance should be performed every 500 shots, or as needed. A list of currently approved maintenance procedures can be found at byrna.com/maintenance. For any service not listed, please contact customer service. The Byrna launcher features a 1-year limited factory warranty that may be voided if unauthorized service is attempted, the launcher is modified, or used with unauthorized projectiles or unauthorized gas cylinders. 

• Always remove the CO2 cylinder and magazine and clear the breech before performing any maintenance.

USING BYRNA OILER KIT (SOLD SEPARATELY)

• Note: Byrna Launchers require lubrication with the Byrna oiler kit every 10 CO2 Canisters.
• STEP 1 Make sure to wear appropriate eye protection,n andandthen follow the instructions: 
• Confirm the safety lever is engaged, (refer to “SAFETY OPERATION” on page 9). 
• Confirm the CO2 cylinder is removed, (refer to “REMOVING THE CO2 CYLINDER” on page 11). Confirm the breech is cleared, (refer to “BREECH INDICATOR” on page 16).
• STEP 2 Place the oiling guide into the CO2 chamber. 
• STEP 3: Insert the oiling tool into the CO2 chamber.
• STEP 4 Squeeze the oil bottle gently to dispense 2-3 drops of oil. Do not overoil.
• STEP 5 Operate the launcher, (refer to “LAUNCHING PROJECTILES” on page 18). Operating the launcher immediately after oiling allows air to force oil through the entire launcher. This step can be performed without firing any projectiles if preferred (i.e. , with an empty magazine); however, make sure to observe all warnings and safety precautions. 

TROUBLESHOOTING

FIRST AID

Chemical irritants may cause serious injury, permanent disabilities , and, in rare cases, death. Children, the elderly,y, and those with chronic diseases are more vulnerable to the effects of chemical irritants.  People with preexisting respiratory conditions,s such as asthma, are likely to need medical attention and may sometimes require hospitalization or even ventilation support. Skin exposure to CS may cause chemical burns or induce allergic contact dermatitis.  When a person is hit at close range or severe exposure to chemical irritants takes place, eye injuries involving scarring of the cornea may lead to a permanent loss in visual acuity. 
In case of accidental discharge or chemical exposure, irritants, seek medical assistance immediately.

AFTER INHALATION:

• Supply fresh air; consult a doctor in case of complaints.
• Provide oxygen treatment if the affected person has difficulty breathing.

AFTER SKIN CONTACT:

• Immediately wash with water, soap, and rinse thoroughly.
• If skin irritation or rash occurs: Get medical advice/attention.

AFTER EYE CONTACT:

• Remove contact lenses if worn.
• Rinse open eye(s) for several minutes under running water. If symptoms persist, consult a doctor.

AFTER SWALLOWING:

• Rinse out your mouth and then drink plenty of water.
• Do not induce vomiting; immediately call for medical help. 
• MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED:
• May cause respiratory irritation.
• Coughing.
• Breathing difficulty.
• Causes eye irritation.
• Allergic reactions.
• Danger: Suspected of causing cancer.
• Route of exposure: Inhalation.

INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED:
