If so, use extreme care. Lock the bolt open with the bolt stop before attempt-

ing to clear the jam. Drawing the bolt fully to the rear may bring the jammed

cartridge along. Keep your face away from the ejection port during this opera-

tion. When attempting to clear a jam, use only wood ‘tools’ so that a cartridge

will not be ignited if you strike a primer, and so that the chamber and maga-

zine will not be damaged. A 3/16” wood dowel rod with a point on one end is

useful.

3. Visually check to make sure all cartridge have been removed from the rifle.

Safely dispose of any cartridges involved in a malfunction incident. Do not use

damaged ammunition in any firearm.

TO MINIMIZE MALFUNCTIONS (“JAMS”)

Most malfunctions are caused by improper or damaged magazines, incorrect

ammunition, or poor maintenance. RUGER

chambers must be scrupulously cleaned at least every 50 shots (see “Care

and Cleaning”, pp. 21 - 22).

1. If it appears that the gun and magazine are not at fault and that the jam was

caused by the type of cartridge being used, then try another type.

2. If changing to another type or brand of cartridges does not at once eliminate

malfunctioning, then the following steps should be taken:

a. Make certain the gun and the magazine are unloaded and that the safety

is “on”. Remember, the magazine should be removed first, then check the

chamber and be certain it and the magazine-well are clear of cartridges.

b. Thoroughly clean the magazine and bolt mechanism, paying particular

attention to removing accumulated grease. Use a bristle brush and solvent

to remove grease and fouling from the bolt face, the extractor, the chamber,

and the feed ramp. (See the “Care and Cleaning” section of this manual for

detailed cleaning instructions).

c. Check to see that the magazine spring tension is adequate.

d. Check the magazine lips to be certain they are free of nicks and burrs and

are not deformed.

e. Remove excess oil and solvent from all cleaned components, load the

magazine, and try the firearm again. As always, proceed slowly. Be certain

bystanders are not close and that you are wearing eye and hearing protec-

tion and that your face is a safe distance from the rifle so that any discharge

resulting from a jammed cartridge will not injure anyone.

If the above procedures do not result in a smooth and reliably functioning

firearm, don’t use the gun. The rifle can be returned directly to our Newport,

New Hampshire Product Service Department for repair. See the Service and Parts

Policy section (p. 24) of this manual for packing and shipping information.

Another precaution: When using any firearm chambered for rimfire cartridges,

form the habit of examining fired cartridge cases. If they have bulged heads or

frequently show splits on any part of the case, the rifle or pistol should be

returned to the factory for inspection.
