  1. PROCEDURE
  2. Uses of Rear Sight

There are five scale marks on the rear sight elevator and one on the slide.  At the target of 50m, the scale mark on the slide is aligned with the third scale mark on the rear sight elevator.  When shooting distance changed, loosen the screws on the rear sight elevator and adjust the slide to the proper position.  In order to install an optical sight, a dovetail groove is made on receiver, when needed, it can aim accurately by means of an optical sight.

4. Operating Procedure

To fire the rifle, turn the bolt handle upward to unlock the breech bolt with the right hand, and pull it rearward until it stops against the bolt stop, push forward the bolt handle, and then turn it downward to its original position to lock the bolt.  At this time, a cartridge is loaded in chamber.  Take aim at the target, the rifle will fire a single round when the trigger is pulled to the point of trigger slack with the index finger of the right hand.

5. Correction of Deflection

If the sight system occurs the deflection (the point of bullet impact deflects from the aiming centre to the left or right).  The adjustment of the rear sight must be taken.  The method is as follows.  A small wood rod or soft metal rod should be used to bear against the side of dovetail in front of the rear sight during tapping.  If a horizontal deflection occurs, tap lightly the dovetail of the rear sight base.  The point of bullet impact deflects from the aiming centre to the left, tap the dovetail to the right, inversely, tap the dovetail to left.  If a vertical deflection occurs, loosen the slide retaining screw with a screwdriver and adjust the slide to a required position, then retighten the slide retaining screw.  The point of bullet impact deflects above the aiming centre, remove the slide downward, inversely, remove the slide upward.

6. Uses of Safety

After the bolt has been locked fully, by turning the safety lever with the right thumb about 45° counter clockwise, be sure that it is moved all the way to the extreme position.  At this time, the safety lock, the firing pin and the bolt handle and place the rifle in the safe condition.  Even if the trigger is pressed, the rifle cannot be fired and the bolt handle cannot be turned either.  Only when the safety is returned to its original position, the rifle can be armed.
