2.5.1. To check the rifle for good condition, as well at to set its
further ready-for-use condition periodically inspect the rifle.
During inspection make sure that all the rifle parts are present and
the external parts are free of rust, dirt, dents, scratches, nicks,
chipping and other damage, since they may interfere with the normal
operation of the rifle mechanisms and the optical sight.
Besides, check condition of the lubricant on the rifle parts visible
without disassembling the rifle. Make sure that the magazines, the
knife bayonet, the accessories, the slip cover for the optical sight,
the carrier for the optical sight and magazines, as well as the bag for
SPTA are not missed, make sure that there is no foreign matter in the
barrel bore.
Check the parts and mechanisms for proper operation. When checking
the operation of the rifle parts and mechanisms, release safety lock,
retract the bolt support by the reloading handle all the way back and
release it; the bolt support should be stopped in the rear position by
the bolt catch.
Detach the magazine, slightly retract the bolt support by the handle
and release it; the bolt support should energetically return to the
front position. Set the rifle at safe and press the trigger; the
trigger should not move rearward completely, and the hammer should
remain cocked.
