AMMUNITION
A GENERAL PRINCIPLES
- There are different types of ammunition for different types of firearms. Your firearm has been designed for ammunition of a specific type
and a specific caliber. It is important to select the proper ammunition for your firearm.
NEVER USE AMMUNITION NOT SPECIFICALLY DESIGNATED FOR USE IN YOUR FIREARM. FAILURE TO USE
THE CORRECT TYPE OR CALIBER OF AMMUNITION MAY CAUSE THE FIREARM TO JAM, FAIL TO FIRE OR EVEN GENERATE EXCESSIVE
PRESSURE WHICH CAN DAMAGE OR EVEN RUPTURE YOUR FIREARM, CAUSING PERSONAL INJURY, DEATH OR PROPERTY DAMAGE.
- You are responsible for selecting ammunition that meets industry standards and is appropriate in type and caliber for this firearm.
- Locate the caliber designation marked on the left side of the lower receiver. This information indicates the ammunition caliber that should
be used in this firearm.
B HANDLOADED OR RELOADED AMMUNITION
NEVER USE NON-STANDARD, RELOADED OR ``HANDLOADED`` AMMUNITION WHICH HAS NOT BEEN
SUBJECTED TO INTERNAL BALLISTIC PRESSURE TESTING. RELOADED OR HANDLOADED AMMUNITION MAY HAVE MANY
MANUFACTURING AND QUALITY VARIABLES (SUCH AS THE TYPE AND AMOUNT OF GUN POWDER). ANY AMMUNITION THAT IS
IMPROPERLY MANUFACTURED, EVEN IN THE SLIGHTEST DEGREE, MAY FAIL TO FIRE OR MAY GENERATE EXCESSIVE INTERNAL
PRESSURES WHICH CAN DAMAGE OR EVEN RUPTURE THE FIREARM, CAUSING PERSONAL INJURY OR DEATH TO THE SHOOTER OR
THOSE IN THE IMMEDIATE VICINITY.
YOUR SAFETY RESPONSIBILITIY
WARNING:
WARNING:

YOUR SAFETY RESPONSIBILITY
- Use only commercially manufactured ammunition with internal ballistic pressure which are in strict accordance with the specifications of
the Sporting Arms and Ammunition Manufacturers´ Institute (SAAMI). If you are uncertain, contact your ammunition supplier for verification.
C AMMUNITION SPECIFICS
- Use only ammunition specifically recommended for your firearm.
- Never mix ammunition.
- Never use a cartridge not specifically designated for use in your firearm.
- Pressure from the wrong type of ammunition may exceed the capability of your firearm and may damage or even rupture your firearm.
- In some cases, a round of ammunition not specified on your firearm may fit into the chamber. Firing ammunition not specified on your
firearm may cause it to rupture and cause serious injury or death to you or others.
- Always inspect your ammunition before using it. Never use dirty, corroded or damaged ammunition which can lead to a burst cartridge
which may cause damage to the firearm and personal injury or death.

FIELD STRIPPING
10.4 Setting of the Bolt Speed
The bolt speed can be adjusted for different ammunition requirements. To reach the screw for bolt speed
adjustment the gun has to be disassembled as described in Section 11 Field Stripping.
Only adjust the bolt speed if problems are encountered when firing a different type of ammunition.
For high velocity ammunition, use the correct size Allen wrench (hex key) to increase the bolt speed by
turning the screw clockwise (fig. 15). First, position the adjustment screw so that the screwhead is flush
with the surrounding surface. Then, incrementally turn the screw clockwise up to a maximum of 9
complete revolutions to achieve maximum performance. Do not turn more than nine (9) turns
clockwise.
For standard ammunition, use the correct size Allen wrench (hex key) to decrease the bolt speed by
turning the screw counter clockwise (fig. 15). The screwhead must never rise above “flush” with the
surrounding surface.
fi g. 15
To mount an optical sight you need a low profile mount (Section 18.2 Accessories). Place the low profile

Any implied warranties, including the implied warranties of merchantability and fitness for a particular purpose, are limited in duration to 1 year
from date of retail purchase. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE
LIMITATIONS MAY NOT APPLY TO YOU. TO THE EXTENT ANY PROVISION OF THIS WARRANTY IS PROHIBITED BY FEDERAL STATE, OR MUNICIPAL
LAW WHICH CANNOT BE PREEMPTED, IT SHALL NOT BE APPLICABLE. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO
HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE AND COUNTRY TO COUNTRY.
UNDER NO CIRCUMSTANCES SHALL UMAREX USA AND CARL WALTHER GMBH BE RESPONSIBLE FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES WITH RESPECT TO ECONOMIC LOSS, INJURY, DEATH OR PROPERTY DAMAGE, WHETHER AS A RESULT OF BREACH OF THIS

SHIPPING GUIDELINES
• Ensure that the firearm is unloaded.
• Do not attempt to ship a firearm via US Postal Service; only federally licensed firearm dealers may ship a firearm by US Postal Service.
• DO NOT SHIP ANY AMMUNITION.
• Enclose a letter which includes your full name and address (no P.O. Boxes, please), daytime telephone number, e-mail address, the serial
number of the firearm, and details of the problem experienced (stating the brand and type of ammunition used when the problem occurred)
or work desired.
• Record the serial number before shipping, in case you wish to check on the repair status of your firearm.
• Please remove all custom parts and accessories, such as stocks, special sights and scopes, or slings from your firearm before returning.
• Place the firearm in its original box and then pack it securely within another container to avoid damage.
• The package must NOT bear any markings which indicate the identity of the contents.
• It is recommended that shipments be insured by the owner, since Umarex USA will accept no responsibility for loss or damage in transit.
• It is most important that you comply with federal, state, and local laws and regulations. The following guidelines are meant to help, but you
must seek assistance from the appropriate authorities if necessary.
• If your firearm must be replaced, it may be necessary to ship the replacement to a dealer rather than directly to you. You will be requested to
furnish a signed FFL (Federal Firearms License) from your dealer in such an instance.
