Setup

1. Initial Inspection

Upon unpacking, inspect the air rifle for any visible damage. Ensure all components, including the scope and mounting rings, are present. It is normal for new air rifles to have a protective grease coating; wipe this off before use.

2. Scope Mounting

Attach the included 4x32mm scope using the provided mounting rings. Ensure the scope is securely fastened to the rifle's rail. Proper alignment is crucial for accuracy. Refer to the separate scope manual for detailed mounting and zeroing instructions.

3. Barrel Break-in

New air rifles, especially break barrel models, often require a break-in period. This typically involves firing approximately 100-200 shots. During this period, accuracy may improve as the internal components settle. The first few shots may be louder due to a phenomenon known as "dieseling," which is normal for new air rifles.

Operating Instructions

1. Loading the Air Rifle

Ensure the air rifle is pointed in a safe direction.
Grasp the barrel and firmly break it downwards until the spring mechanism engages and the automatic safety is set.
Insert a single .177 caliber pellet into the breech. Ensure the pellet is seated correctly.
Return the barrel to its original position, ensuring it locks securely. The automatic safety will remain engaged.

2. Firing the Air Rifle

With the air rifle loaded and the safety engaged, aim at your target.
When ready to fire, disengage the automatic safety.
Place your finger on the trigger and squeeze gently to fire.
After firing, the air rifle must be re-cocked and re-loaded for the next shot. The automatic safety will reset.

3. Pellet Selection

For optimal performance and accuracy, experiment with different brands and types of .177 caliber pellets. Pellet weight and shape can significantly affect accuracy and velocity. The rifle is rated for velocities up to 1000 fps with appropriate pellets.

Maintenance

1. Cleaning the Barrel

Regularly clean the barrel using pull-through patches until they come out clean. Avoid using harsh solvents that could damage the barrel's rifling or finish.

2. General Care

Wipe down all metal parts with a lightly oiled cloth to prevent rust. Inspect the wooden stock for any signs of wear or damage. Store the air rifle in a dry, secure location.

3. Stock Bolt Maintenance

Periodically check the stock bolts for tightness. It is recommended to check and tighten them every 20-30 rounds during the initial break-in period. For long-term stability, consider applying a small amount of blue thread locker (e.g., Loctite 242) to the stock bolts once the rifle is fully broken in and consistently accurate.

Troubleshooting

Problem	Possible Cause	Solution
Inconsistent Accuracy	Incorrect pellet choice Loose scope mounts Barrel droop (common in break barrels) Rifle not fully broken in	Experiment with different .177 pellets (e.g., H&N Baracuda Match, Field Target Trophy). Ensure scope mounts are tightened, consider blue thread locker. If significant barrel droop, consider a compensating scope mount. Continue break-in period (100-200 shots).
Loud First Shots / "Dieseling"	Excess lubricant or residue in the compression chamber.	This is normal for new air rifles and typically subsides after the first few shots as the rifle breaks in.
Missing Scope Mounts	Packaging error or missing components.	Contact Beeman customer support or the retailer for assistance.
