SAFETY INSTRUCTIONS

Always follow the safety instructions for your safety and the safety of others.

1. Always handle your firearm as if it were loaded.

2. Never point your firearm at anything you do not intend to shoot.

3. Never take anyone's word that a gun is unloaded.

4. Always make sure that your firearm is not loaded before laying it down, or handing it to another person.

5. Always store your rifle unloaded with the striking mechanism released.

6. Never abuse your firearm by using it for any purpose other than shooting.

7. Never leave a loaded firearm unattended.

8. Prior to loading the firearm make sure that barrel bore, chamber, and action are clean and clear of obstructions. Clean a dirtied firearm immediately so that it will function properly and safely.

9. Always use only clean, dry, original high quality commercially manufactured ammunition, which is appropriate to the caliber of your rifle.

10. Never drink alcoholic beverages or take drugs before or during shooting.

11. Always wear safety glasses and ear protection during shooting whenever possible.

12. Always keep the safety on when the rifle is loaded with cartridge in the chamber, until you are ready to fire. Keep firearm pointed in a safe direction when disengaging the safety.

13. A rifle with an activated set-trigger should be handed with maximum care, as even jolts during handling operations could cause an unintended discharge.

14. Always keep clear and keep others clear of the ejection port.

15. Never squeeze the trigger or put your finger in the trigger guard until you are aiming at a target and ready to shoot.

CZ 550 - INSTRUCTION MANUAL

16. Always be absolutely sure of your target, and the area behind it, before you squeeze the trigger. A bullet could travel through or past your target up to several hundred meters.

17. Never shoot at a hard surface such as rock, or a liquid surface such as water.

18. Never fire your firearm near an animal unless it is trained to accept the noise.

19. Never indulge in "horseplay" while holding your firearm.

20. Failure to fire: always hold the firearm, keeping it pointed towards the target, or a safe open area and wait 30 seconds when the firearm fails to fire. If a hangfire (slow ignition) has occurred, the round will fire within 30 seconds. If the round does not fire, remove the magazine, eject the round and examine the primer; if the firing pin indent on the primer is light, or off center, or non-existent, have the rifle examined by a competent gunsmith.

21. Always make sure your firearm is not loaded before cleaning, storing or travelling.

22. Always keep and store your firearm and ammunition in separate locked receptacles out of reach and sight of children and untrained people.

23. Never alter any parts of your rifle as the safety and proper function of your rifle could be seriously compromised.

24. Always be aware that corrosion, use of damaged ammunition, dropping the rifle on hard surfaces or other "coarse treatment" could cause a damage you may not see. If something like this happens, allow let the firearm to be examined and tested by a competent gunsmith.

CZ 550 - INSTRUCTION MANUAL

OPERATING INSTRUCTIONS Ammunition

Use only factory-manufactured standard ammunition of appropriate caliber, which are in compliance with CIP regulations (International Proof Commission for Firearms and Ammunition) or SAAMI (Sporting Arms and Ammunition Manufacturers' Institute Inc. of the United States). The use of other cartridges could damage the firearm or cause malfunctions or injury to the shooter.

Magazine Removal

(Pertains only to rifles equipped with detachable magazines). With one hand depress in the forward direction magazine catch located at the front part of the trigger guard (Fig. 2). Remove with the other hand the magazine.

Magazine Loading

(Pertains only to rifles equipped with detachable magazines). With the open end uppermost, grasp the magazine in one hand. Place a cartridge on the magazine follower with the base just forward of the retaining lips. Press the cartridge down and back until its base touches rear flat edge of the magazine. Place the next cartridge on top of the previous cartridge and slide in as already described.

Loading of the Rifle

ALWAYS MAKE SURE THE RIFLE IS POINTED IN A SAFE DIRECTION WHEN LOADING!

The rifle in detachable magazine version

First push in the full magazine by its front side obliquewards until it stops, then push the rear side (Fig. 3).

Grip the rifle with the left hand by its fore-end, place the buttplate against your body and grip the bolt handle with the other hand. Open the bolt by raising the bolt handle and pulling to the rear to its stop. Then push the bolt vigorously to its forward position again and by rotating the bolt handle in a downward direction close the bolt action. This procedure inserts the cartridge into the cartridge chamber and cocks the striker mechanism. The rifle is now ready to fire. If you do not intend to fire immediately, ensure the firearm safety as described further in the section Safety and its Operation.

Note:

Loading is also possible for single cartridges by directly inserting into the chamber without the use of a magazine.

CZ 550 - INSTRUCTION MANUAL

The rifle in magazine box version

Open the bolt by raising the bolt handle and pulling to the rear to its stop.

Place a cartridge on the follower and press it downward into the magazine box. After releasing the downward pressure, the cartridge is caught by the side walls of the magazine. Place the next cartridge on top of the previous one, and slide in as described above. When the magazine box is loaded, push the bolt vigorously to its forward position, and by rotating the bolt handle in a downward movement close the bolt. This procedure inserts the cartridge into the cartridge chamber, and cocks the striker mechanism. The rifle is now ready to fire. If you do not intend to fire immediately ensure the firearms safety as described further below in the section Safety and its Operation.

Unloading of the Rifle

ALWAYS MAKE SURE THE RIFLE IS POINTED IN A SAFE DIRECTION!

- open the magazine box floorplate (Fig. 4) and drop released cartridges into your hand (in the detachable magazine version, remove the magazine in the manner as already described - see operating instructions, removal of the magazine)

- move the safety to its "Safety-Off" position in order that the bolt can be opened. If your rifle is fitted with a threeposition safety, shift it to its mid-position which allows the bolt operations, but the trigger mechanism remains on safe

- open the bolt and check to ensure that the cartridge has been extracted from the chamber and ejected

- close the bolt

- depress the trigger (dry fire)

The Safety and its Operation

Shift the safety rearward to its "Safety-On" position (Fig. 5) until the red dot is fully covered. This procedure locks the

trigger mechanism and the bolt, it is not possible to discharge a cartridge or manipulate the bolt.

If your rifle is fitted with a three-position safety, it has an additional mid-position which permits the opening of the bolt,

but the trigger mechanism remains on safe. At this position of the safety, only the white dot is showing.

Cocking Indicator Operation

The cocking indicator is located on the rear face of the bolt sleeve (Fig. 6). If the (striker) firing pin is cocked, the

cocking indicator protrudes from the bolt sleeve. This protrusion can be checked both by sight and by touch.

CZ 550 - INSTRUCTION MANUAL

Set-trigger Operation

The set-trigger is activated by pushing it in the forward. For the reason of safety, activate the set-trigger only after the rifle is loaded and shortly before shooting. Do not carry your rifle with an activated set-trigger! If you have activated the settrigger and you do not follow through with firing, keep your firearm pointed in a safe direction while carefully engaging the safety and then squeeze the trigger. Subsequently unload the rifle in the manner described above.

Trigger Adjustment

Independent of whether there is a mounted set-trigger or not, the trigger mechanism can be adjusted with respect to the trigger pull weight, and the trigger travel, before and after discharge. The adjustment can be performed after taking the barreled action out of the stock by means of the setting screws A (trigger pull), B (trigger travel before) and C (trigger travel after discharge) - see Fig. 7.

If the CZ 550 rifle is fitted with a set-trigger, the adjustment of the set-trigger is carried out by the screw located in front of the trigger (Fig. 8). For safety reasons do not adjust the set-trigger travel as too short, as the rifle with an activated settrigger is very sensitive to shock, and during handling the rifle could unintentionally discharge. The safety of the set-trigger adjustment can be checked with the rifle unloaded by repeated opening and closing of the bolt combined with moving of the safety to its "ON" and "OFF" positions. The spontaneous release of the trigger must not occur.

Note:

There is a possibility of dismantling the set-trigger from the rifle, without any impairment to the functional properties or adjustment of the conventional trigger.

Sight Adjustment

The elevation and windage correction is carried out after loosing the screws H (horizontal) and V (vertical) by shifting the rear sight blade (Fig. 9). One part displacement changes the point of aim at 100 m distance in vertical by 3 cm and in horizontal direction by 15 cm.

Rifle Scope

Mounting of the riflescope and sighting-in of the rifle should be entrusted to a qualified gunsmith's workshop.

CZ 550 - INSTRUCTION MANUAL

MAINTENANCE INSTRUCTIONS Stripping for Cleaning - Disassembly

1. Remove the magazine. With the magazine box version, open the floorplate and remove the cartridges.

2. Shift the safety to its "SAFETY-OFF" position in order that the bolt can be manipulated.

3. Open the bolt, and after depressing the bolt stop (Fig. 10), pull the bolt rearwards out of the receiver.

Disassembly of the Bolt

BEFORE BOLT DISASSEMBLY CHECK FOR YOURSELF THAT THE CARTRIDGE CHAMBER IS EMPTY.

Cock the firing mechanism by opening the bolt, move it slightly backwards and close it again. Press the disassembly catch (Fig. 6) and keep it depressed, while at the same time open the bolt and move it partially rearwards with the other hand. Unscrew the bolt sleeve together with the firing pin assembly and as already described above pull the rest of the bolt rearwards out of the receiver.

CAUTION:

Do not strip your firearm any further. If you assume that your firearm requires adjustment or repair, entrust this work to a competent gunsmith in a specialized workshop!

Cleaning the Rifle

Clean the Rifle

- each time you use it

- if you get your rifle wet

- as soon as possible after shooting

- at least once a year in a temperate climate

- as often as once a month in a tropical climate, or other demanding environment

CZ 550 - INSTRUCTION MANUAL

Cleaning the Barrel Bore and the Cartridge Chamber

If the firearm has not been fired or if only a few cartridges have been fired clean the barrel bore and cartridge chamber by the clean patch attached to the cleaning rod. Repeat the cleaning, changing patches, until the last patch comes out clean.

When the barrel bore is very dirty, apply a gun cleaning solution using cleaning brush. Let the solvent act for about 10 minutes (this time may vary depending on the solvent agent being used). Then thoroughly scrub out the barrel bore. Subsequently, dry the barrel bore and cartridge chamber with a clean patch and check that all powder residues, or fouling have been removed. If necessary repeat this procedure.

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 bore before reversing the movement. If you try to change directions with the brush in the barrel, the brush could stick.

Cleaning of Other Rifle Parts

Other parts of the rifle can be cleaned with a dry cloth, old toothbrush, copper bristle brush or a wooden scraper. Preserving oil or paraffin oil can be used for proper cleaning. Never use the agent designed for barrel bore cleaning! These solutions could remain in the joints, and after some time could cause corrosion. Check that cloth particles or brush bristles have not become lodged in any part of the rifle.

The maintenance of the stock can be carried out with a dry cloth or by some furniture-polishing product.

Preserving

When the barrel bore, cartridge chamber, and all accessible parts are clean and dry, wipe these parts with a cloth soaked in gun oil or apply the oil in a spray. Remove all excess oil.

Before the shooting always wipe the barrel bore dry. At very low temperatures remove the oil from all accessible parts or apply a lubricant prepared especially for these conditions.

Use thick preserving agents for example, preserving grease only for long-term storage in demanding climate environments, and before any use of the rifle, it must be thoroughly removed from all parts of the firearm.

CZ 550 - INSTRUCTION MANUAL
