L NOTICEThe safety can only be engaged when the rifle is cocked. In case the rifle is not cocked the safety bounces back to its forward posi-tion.

The manual safety is to minimize the potential for firing in the event of an unintentional pulling of the trigger. The manual safety and the rifle’s other safety features provide only partial protection against firing from other causes. The safety is only a mechanical device. It is not a substitute for safe firearm handling.

WARNING!Don’t shoot unless you are absolutely sure of your target and what is beyond it. Remember that a bullet from the rifle can cause serious injury or damage even at a distance of 8 kilometers (5 miles).

Always store your firearm absolutelyunloaded in a secure, dry place, where itwill not be damaged and where childrenand unauthorized persons cannot gainaccess to it. Also, keep cartridges storedseparatelyinasecureplace.

L NOTICEAlways follow the national legis-lation and regulations concern-ing the storage of the rifle. Rules depend on the country.

Follow the instructions supplied with the suppressor when attaching the suppressor to the rifle. Never store the rifle with the suppressor on.

CAUTION!

Even with a small number of rounds, the suppressor becomes extremely hot during firing. Use protective gloves or cloth when inspecting tightness or when removing the suppressor in order to avoid burn injuries.Do not shoot with a loose or misaligned suppressor.

WARNING!

Attachment of the suppressor may become loose during firing due to heat expansion. Verify proper tightness of the suppressor periodically during firing.

CAUTION!Unstable or projectiles that disintegrate after the muzzle (frangible, sabot etc.) are not to be shot through the suppressor. If in doubt, further information can be received from the manufacturer.

es,clothpatchtip,cleaningpatches).2. Screwdrivertypehexkey1,5mm3. Screwdrivertypehexkey4mm4. Screwdrivertypehexkey5mmFor continuous and routinemaintenance,we recommend to use full-sized high-qualitytools.

When fired even a minor obstacle in the barrel may lead to a permanent damage to the rifle and cause a severe injury to the shooter or bystanders.

WARNING!

Always read instructions and precautions of all chemical products. Make sure that the chemical is suitable for corresponding use.

WARNING!

Be careful when cleaning “soft touch”, camouflage or other special finishes. Too powerful rubbing and improper cleaning agents may damage these finishes.

CAUTION!

Use only lubricants and chemicals provided with the rifle or the ones that have been previously approved for maintenance of small arms.Excessive amount of oil gathers dirt particles which can interfere with reliable fuctionality of the rifle. Moreover, the dirt in the barrel may, when fired, cause deformation in the barrel and render the barrel unserviceable.Never use emery paper, sand paper or other abrasive products to clean the rifle, especially the bore.

CAUTION!Make sure the rifle is not loaded with ammunition and that the magazine is out of the rifle before any kind of cleaning or maintenance procedures.
