3. Again, raise the bolt handle and draw the bolt fully
to the rear.

The bolt has been carefully selected and fitted at the
factory to assure correct headspace. The bolt is etched
with your rifle’s serial number for identification purposes.
To assure your safety, never interchange bolts, as they
may not have the proper head space. If the bolt is lost or
damaged, return your rifle to the factory for replacement
with a properly fitted bolt.

The barrel and action of this rifle have been made with
substantial safety margins over the pressures developed
by established American loads. However, we assume
no responsibility for incidents which occur through
the use of cartridges of nonstandard dimension or
those developing pressures in excess of SAAMI

The bolt of your rifle may have been packed separately
in the carton in which your rifle is shipped. You will
need to insert the bolt into the action. In addition,
it is always advisable to remove the bolt before cleaning.
Consequently, becoming familiar with removing
and inserting the bolt assembly quickly and easily
is absolutely essential.

Before inserting the bolt into your Model 70 for the first
time, make sure the firing pin is cocked and the “safety”
is in the intermediate position. Under most conditions it
should be (and remain) cocked. When the firing pin is
cocked, the cocking indicator is visible at the rear of the
bolt. If the indicator is protruding from the bolt sleeve a
minimum of 1 /

", the firing pin is cocked. If the firing pin
is not in the cocked position this means that the bolt has
been partially disassembled. To remedy this simply turn
the rear section of the bolt — clockwise when viewed
from the indicator end — until the bolt sleeve lock
engages the notch in the bolt (Figure 11). On a new gun
where surfaces are not yet burnished from use, it may be
difficult to rotate the bolt sleeve by hand. If so, carefully
grasp the lower section of the firing pin in a padded vise,
pull and turn.

3. Push fully forward and lower the bolt handle down to
a locked position. The “safety” can now be operated.

in) either the intermediate or rear on safe positions.
