Overview

The Byrna SD is built for durability, but regular maintenance is essential to keep it operating at peak performance. The most important part of maintenance is routine oiling, which protects internal seals and ensures proper pressure and function.

Proper lubrication supports smooth operation, consistent velocity, and reliable firing. Without it, performance can decline due to seal wear, air leaks, or pressure inconsistencies. By sticking to a regular maintenance schedule, users can extend the lifespan of their launcher while maintaining dependable performance.

Maintenance Schedule

To keep the Byrna SD in optimal condition, oiling should be performed:

• Every 10 CO2 cylinders, or
• Every 3-6 months if the launcher is not used frequently

This schedule ensures proper lubrication whether the launcher is used often or stored for extended periods.

Oiling Methods

Method 1: Oiler CO2 Cylinder (Recommended)

• Insert an oiler CO2 cylinder into the launcher
• Fire the launcher normally or dry fire
• Oil is distributed automatically throughout the internal system

Method 2: Oiler Kit

• Apply lubricant manually using a Byrna oiler kit
• Follow product instructions to ensure proper distribution
