!WARNING – LEAD EXPOSURE
Discharging firearms in poorly ventilated
areas, cleaning firearms, or handling
ammunition may result in exposure to
lead and other substances known to the
state of California to cause birth defects,
reproductive harm, and other serious
physical injury. Have adequate ventilation
at all times. Wash hands thoroughly after
exposure.

Practice the important aspects of gun handling described below (with an

Never carry the rifle loaded with the safe-
ty selector in the “FIRE” position.If
dropped or struck with the safety off, the
rifle may fire. Such a discharge can occur
with or without the trigger being directly
struck or touched. Never rest a loaded
rifle against any object. (wall, fence, vehi-
cle, tree, etc.) because there is always the
possibility that the rifle will be jarred or
slide from its position and fall with suffi-
cient force to discharge. Keep safety on
unless actually firing.
Never lower...

This precision trigger has been
carefully adjusted at the factory
and permanently secured. Do
not alter any factory setting! You
can create an unsafe condition
and the rifle may fire unexpect-
edly, or not fire at all.
You should be especially careful
to keep the safety on at all times
except when actually firingand
keep your finger of
f the trigger
unless you are squeezing it to
fire,in order to minimize the
possibility of accidental dis-
charge.
DO NOT TAMPER

KEEP SAFETY ON UNLESS FIRING...

When there is a cartridge in the cham-
ber and the safety selector is in the
“Fire” position, the cartridge will dis-
charge if the trigger is pulled. It is
absolutely essential for the user to know
how to completely unload it.
“Completely” means fully opening the
lever, removing a chambered cartridge,
and checking to be sure the rifle is
empty. The safety selector should always
be in the “Safe” position when the rifle
is being unloaded.See the “Operation of
Safety” section of this manual.
ALWAYS CHECK...

CARTRIDGE EXTRACTION AND EJECTION
When the lever is lowered the fired cartridge case is automatically extracted and
ejected. Check the chamber to be sure it is empty before closing the lever. If
automatic ejection is not desired, remove the forearm and back-off the ejector
strut adjustment screw until the ejector spring unit can be removed.
(See Figure 4) The ejector will then function as an extractor only, and the car-
tridge (or fired cartridge case) will be partially removed from the chamber by...

If a cartridge hangs up, jams, or binds
when being chambered or when the
breech block is closed, do not attempt to
force it into the chamber by pushing or
striking the lever. Most failures of a car-
tridge to feed or to chamber are caused by
ammunition that is incorrect, dirty, or
defective.
Whatever the cause, the gun user must,
above all, recognize that jams can result
in the very potentially dangerous situation
of a cartridge discharging before it is
chambered. If this occurs, the cartridge
case will...

To minimize the possibility of such occurrences the gun user should:
–Use ammunition of the correct caliber and type which is loaded to U.S.
Industry Specifications. Do not use cartridges that are deformed, or car-
tridges that have been reloaded.
–Clean and lubricate the gun in accordance with the instructions in this
manual.
–Learn to correctly operate the lever and how to properly load and empty
the chamber.
–If the mechanism shows signs of not functioning correctly, or if a part is
damaged or...

position of the part in the gun before starting to remove it. If a part is under
spring tension (such as, the Safety or Trigger) remove it cautiously and anticipate
the direction the spring and plunger are most likely to “jump.”
WARNING: If a spring or plunger become lost do not use a substitute. Springs of
correct tension are vital to the safe and reliable performance of firearms. Before
starting disassembly, remove the sling, scope and rings and place the rear sight
blade in its down flat position....

3. Check the sights for tightness, setting and alignment.
4. Rest the forend on your hand, not
directly onto a rest. Neverrest the barrel
directly onto a rest.
If everything is tight, the bore is clean, the sights are properly aligned and secure
but the accuracy problem persists, DO NOT alter the stock bedding in any way.
Do not scrape away wood and do not bed with “glass,” plastic, epoxy, etc. Once a
rifle stock has been altered, it cannot be reworked by our Product Service
Department.
