Setup
1. Initial Inspection
Carefully remove all components from the packaging. Inspect the air gun and accessories for any signs of damage during shipping. If any damage is found, do not attempt to use the air gun and contact customer support immediately.
2. Filling the PCP Air Tank
The M25W is a Pre-Charged Pneumatic (PCP) air gun and requires an external air source (e.g., high-pressure hand pump, scuba tank, or compressor) to fill its internal air reservoir. Locate the fill port, typically at the front of the air cylinder. Use the provided fill probe and connect it to your air source. Fill the reservoir to the recommended pressure (refer to specifications for maximum pressure). Do not overfill.

3. Loading the Magazine / Single-Shot Tray
The M25W utilizes a new magazine design for multi-shot capability and also supports an optional single-shot function for precision. To load the magazine, insert pellets of the correct caliber (5.5mm / .22 Caliber) into each chamber. Ensure pellets are seated correctly. For single-shot use, insert a single pellet directly into the breech or single-shot tray after cocking the bolt.

Operating Instructions
1. Cocking the Air Gun
With the air gun pointed in a safe direction, operate the bolt action lever. Pull the bolt fully rearward until it locks into place. This action cocks the hammer and prepares the air gun for firing. If using the magazine, this action will also index the next pellet into the breech.

2. Engaging/Disengaging Safety
The M25W features a manual safety. Before firing, ensure the safety is disengaged (FIRE position). When not ready to fire, always engage the safety (SAFE position). Familiarize yourself with the safety mechanism's location and operation before use.
3. Firing the Air Gun
Once the air gun is cocked, loaded, and the safety is disengaged, aim at your target. Place your finger on the trigger only when you are ready to shoot. Slowly and steadily squeeze the trigger until the air gun fires. After firing, keep the air gun pointed in a safe direction until you are ready for the next shot or to unload.
4. Adjusting Trigger Pull
The trigger pull on the M25W is adjustable from 2-5 Lbf. Refer to the tooling set for the appropriate wrench or screwdriver. Adjusting the trigger pull can customize the shooting comfort and precision. Make small adjustments and test the trigger pull carefully to avoid accidental discharge.
Maintenance
1. Cleaning
Regular cleaning is essential for maintaining the accuracy and longevity of your air gun. Clean the barrel periodically using a cleaning rod and appropriate patches. Avoid using harsh solvents that could damage seals or finishes. Wipe down the exterior with a soft, dry cloth after each use to remove dirt and moisture.
2. Lubrication
Apply a small amount of silicone oil to moving parts, such as the bolt and trigger mechanism, as needed. Do not over-lubricate. Avoid petroleum-based oils, as they can damage rubber seals in PCP systems.
3. Storage
Store the air gun in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the air gun is unloaded and the safety is engaged before storage. It is recommended to store the air gun with some air pressure in the reservoir (e.g., 1000-1500 PSI) to maintain seal integrity, but not at maximum pressure for extended periods.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Loss of Air Pressure | Leaking seals, improper fill probe connection | Check fill probe connection. Inspect O-rings and seals for damage; replace if necessary. Contact support if leak persists. |
| Pellet Not Firing / Low Power | Insufficient air pressure, incorrect pellet size, misfeed | Check air pressure gauge and refill if low. Ensure correct 5.5mm (.22 Caliber) pellets are used. Verify magazine is properly seated or pellet is correctly loaded in single-shot mode. |
| Bolt Action Stiff | Lack of lubrication, dirt/debris | Clean the bolt and receiver area. Apply a small amount of silicone lubricant to the bolt. |
| Trigger Not Resetting | Internal mechanism issue, debris | Ensure the air gun is unloaded and de-pressurized. Do not attempt to disassemble the trigger mechanism unless you are a qualified technician. Contact support. |
