12. CARE & MAINTENANCE
NEVER STORE A LOADED OR COCKED AIRGUN. Unload projectiles from the airgun and degas
it completely. Keep the airgun away from children and untrained shooters. Store projectiles
separately from the airgun to keep them from untrained shooters. Protect your airgun from
moisture and dirt; clean airgun and wrap it in a smooth, dry cloth. If you are going to store
your airgun for an extended length of time, be sure the barrel is protected. This can be
Oils that contain acid or resin can damage seals and possibly the finish of
the airgun.
Before any care, cleaning or maintenance, always be sure your airgun is on SAFE, is unloaded, and empty
of air. Keep it pointed in a safe direction. It is important to perform routine inspections and maintain your
airgun properly.

PROBLEMS
11C. REMOVING A JAMMED PROJECTILE
If a projectile is jammed in the barrel, DO NOT reload or try to fire the air rifle again.
If you believe the air rifle is jammed, keep pointed in a safe direction, engage the manual
safety and field safety screw (Section 2), degas the rifle (Section 4), remove the magazine
(Section 9), and insert the correct caliber ramrod (at least 32" in length) into the muzzle
and push out the jammed projectile. Do not try to reuse that projectile. If you are not able to
unjam your airgun, contact Umarex USA’s Service Department.
11D. IF THE GUN EXPELS ALL AIR
While rare, the Umarex Hammer could expel all the contents of its air reservoir when
the valve is dirty. If this happens,first follow degassing procedures (Section 4 in this
manual).Then make sure it is pointed in a safe direction, on safe, it is unloaded and an
empty magazine is inserted in the magazine well. Verify it is unloaded and pointed in a
safe direction. Cock the rifle and dry fire it. Refill the gun with air (see Section 3B). If air
continues to leak from the barrel, repeat the process.
11B. UNLOADING PROJECTILES FROM MAGAZINE WHEN THE GUN IS NOT COCKED
To unload a projectile from the Umarex Hammer, always keep the barrel pointed in a safe
direction. Put the rifle ON SAFE by engaging the manual safety on the right side of the
receiver (Section 2A). Then remove the magazine (Section 9) and push the projectile(s) out
of the magazine. Visually inspect the breech to verify a round is not in the barrel. Always
reinsert the EMPTY magazine in the magazine well.
