AIR RIFLE DESCRIPTION AND TERMINOLOGY 
The names of all air rifle parts are listed in the section Illustration and List of Parts. 
The Slavia 630 break-barrel air rifle is intended for leisure activities and basic training in sport shooting. The air rifle 
features a rear sight adjustable for elevation and windage and the trigger is provided with an adjustable trigger pull. The 
automatic safety secures the air rifle against any accidental discharge during cocking. The stock is made of beech wood 
and is designed so as to be ambidextrous.  
						

							SLAVIA 630, 631  -  INSTRUCTION MANUAL  15 The Slavia 631 break-barrel air rifle is intended for general sport shooting and to this purpose its design has been 
adapted. The more robust stock is now made either from beech wood with a polyamide buttplate or plastic with an 
adjustable buttplate. The barrel is fixed in its idle position, the receiver is factory milled for a receiver sight or scope mount. 
The rear sight is adjustable for elevation and windage and the trigger pull weight is adjustable as well. The adjustments 
are carried out manually or with the use of a regular coin without need of special tools. Also this version is equipped with 
an automatic safety. 
 
 
OPERATING INSTRUCTIONS 
 
Ammunition 
When shooting use only Diabolo pellets or 4.5 mm (.177) shots. The use of smaller shots, nails, little stones etc. can 
cause damage to the barrel bore. Additionally there is a danger that such an object may fall through the bypass channel 
into the air tube resulting in damage to the seal and other functional surfaces. 
 
Air rifle Cocking and Loading 
ALWAYS MAKE SURE THE AIR RIFLE IS POINTED IN A SAFE DIRECTION WHEN LOADING! Hold the forend of the air rifle in the right (left) hand and press the stock with your elbow or arm towards the body    (Fig. 1). With the other hand grasp the barrel as close to the front sight as possible. Then apply downward pressure on the 
barrel until you hear a distinct click sound. This sound assures you that the weapon is cocked with the safety on, thereby 
preventing any unintentional discharge. The automatic safety protrudes from the rear face of the receiver (Fig. 2) and its 
white neck indicates the safe position. 
Ease the pressure on the barrel, now insert a Diabolo pellet or 4.5 mm (.177) shots into the breech end of the barrel and press 
it flush with the end (Fig. 3). Then gradually return the barrel to its initial position. Now the air rifle is ready to fire while the safety is 
still on. The safety is disengaged by pressing the safety inside the receiver (white strip disappears). Disengage the safety of the 
weapon just before you intend to shoot, making sure the air rifle is pointed in a safe direction. 
The air rifle can also be put on safe mode anytime by pulling the safety out.  
						

							SLAVIA 630, 631  -  INSTRUCTION MANUAL 16 Trigger Pull Adjustment 
The trigger pull is adjustable in about 3-10 N range. For safety reasons the trigger pull has been adjusted at the factory 
to the maximum setting. Adjustments can be carried out only after removing the stock from barreled action (it is necessary 
to unscrew both front screws and rear screw of the stock). Loosen the spring which is slipped on the trigger (Fig. 3) and 
shift it to the lower recess or as the case may be take it out entirely. Then rescrew the stock on to the barreled action. 
During this procedure follow illustrations 4, 5 and 6: 
– place the barreled action on a mat with the trigger facing upwards, put the cocking lever into the groove in the 
receiver and piston (Fig. 4) 
– put the guide (Fig. 5) into the stock, so as to hold the guide in its place apply some preserving grease to the central 
section 
– slide the stock from above onto the barreled action (Fig. 6), install the screws and tighten them properly 
 
Be more careful when handling the air rifle with the trigger pull weight reduced ! 
 
Sight Adjustments 
The air rifle has been sighted-in at the factory with an air rifle target at a distance of 10 m (11 yards). When you want to 
shoot at other distances or under different shooting conditions, it will be necessary to adjust the sights. 
Elevation correction is performed by a rear sight vertical screw (Fig. 7) Turning the rear sight vertical screw to the right 
elevates the rear sight (and in turn, the point of impact on the target). One full turn of the elevation screw adjusts the 
height by 3 cm (1.2 in) at a distance of 10 m (11 yards). 
Windage correction is performed as shown in Fig. 8. Partly lift up rear sight blade and move it to the side where you 
want your point of impact on the target to be shifted. Moving the blade by one spacing of the serration shifts this point of 
impact by 1 cm (.4 in) at a distance of 10 m (11 yards).  
						

							SLAVIA 630, 631  -  INSTRUCTION MANUAL  17 THE SLAVIA 631 MODEL DIFFERENCES 
Cocking and Loading of Air Rifle 
Hold the forend of the air rifle in the right (left) hand and press the stock with your elbow or arm towards the body. With 
the other hand grasp the barrel close to the barrel housing, pull the pull bar to the front with the thumb and slightly tilt the 
barrel (Fig. 9). Then hold the barrel as close as possible to the front sight and apply downward pressure on the barrel to 
cock the air rifle. 
Further proceedings are the same as with the Slavia 630 air rifle. When returning the barrel to its initial position the 
locking pull bar self-locks into place. 
 
Trigger Pull Adjustment 
The trigger pull is adjustable in the 3-10 N range. For safety reasons the trigger pull has been adjusted at the factory to the 
maximum setting. Adjustments can be carried out with the screw located at the front part of the trigger guard (Fig. 10). By unscrewing 
the adjusting screw, the trigger pull weight is reduced. One full turn changes the trigger pull weight approx. .5 N. For easier operation, 
the screw is provided with a wide coin slot. Be more careful when handling the air rifle with the trigger pull weight reduced! 
 
Sight Adjustments 
The air rifle has been sighted - in at the factory with an air rifle target at a distance of 10m (11 yards). When you want 
to shoot at other distances or under different shooting conditions, it will be necessary to adjust the sights. 
Elevation correction is performed with the elevation dial knobs (Fig. 11). Turning the elevation dial knobs to the higher 
numbers elevates the rear sight (and, in turn the point of impact on the target). Turning the elevation dial knobs by one number 
shifts the point of impact by 3 mm at a distance of 10 m (11 yards). Windage correction is performed by a windage screw which 
is provided with a wide coin slot (Fig. 11). Turning the screw to the right shifts the rear sight to the right (and, in turn the 
point of impact on the target). For the checking there are scale lines on the rear sight leaf and the rear sight blade. One full 
turn of the windage screw shifts the point of impact by 10 mm at distance of 10 m (11 yards). 
WARNING: The numbers on the elevation dial knobs are just informative and do not refer to the actual range. 
 
Using the scope and receiver sight 
The Slavia 631 air rifle is provided with grooves on the receiver for the scope or receiver sight attachment.  
						

							SLAVIA 630, 631  -  INSTRUCTION MANUAL 18 MAINTENANCE INSTRUCTIONS 
Cock the air rifle only a short time before shooting. Unnecessary cocking causes fatigue of the main spring and 
subsequently decreases the power. From time to time check the tightening of both front screws and also the rear screw of 
the stock and if necessary tighten them. 
After a few hundred shots, but at least once every 3 months the air rifle should be cleaned and preserved. Wipe the 
barrel bore with a clean and dry patch attached to the end of a cleaning rod. Repeat changing patches until the last patch 
comes out clean. When the barrel bore is very dirty clean it with a brush dipped into gun cleaning solution or into an oil. 
Wipe the barrel bore dry with a clean patch and check that all the lead residues have been removed (lead is more mat and 
darker than the steel surface). In case of need repeat this procedure. 
Finally preserve the barrel bore and all metal parts with a cloth soaked in gun oil. With the barrel cocked dip 1 or 2 
drops of oil into the air channel in the body tube to lubricate the piston seal and also the body tube inner surface. Remove 
all excess oil. 
The cleaning rod and the brush must be inserted into the barrel bore from the chamber to prevent wear or damage to 
the muzzle. Pass the brush all the way through the barrel before reversing the movement. If you try to change directions 
with the brush in the barrel, the brush could stick. 
The maintenance of the stock can be carried out with a dry cloth or by some furniture polishing product. 
Keep your air rifle stored in a dry and dust-free environment. Regular care and proper handling will keep your air rifle 
looking always as new and its functioning will not be compromised. 
 
Piston Seal Replacement 
Using a screwdriver remove the piston seal by levering it out (Fig. 12). If the seal remains in the air rifle body tube, 
push it downwards, and to the hole in the center, screw - in a long enough rod provided with the M5 thread. Then by 
gradually pulling take the rod with the seal out. 
Press the new seal with the hand on to the piston front. To facilitate this operation the seal can be lubricated with 
a preserving grease or heated in oil to 50°C hot. In no case is the seal to be allowed to be forced on! After correct 
installation, there must be no gap between the seal and the piston front. Proceed carefully when introducing the piston 
back into the tube to avoid damage to the seal.
