Ruger P89DAO Double Action Only Instructions Manual

							TO REASSEMBLE
1.Be certain chamber and magazine are empty.
2. With slide held upside down, replace barrel and push it rearward into its
locked position.
3. Replace guide rod and recoil spring assembly (the smaller diameter end of
spring against collar) into position. Rear end of guide rod seats against barrel
lug. Barrel link must be in vertical (hole showing) position, or pistol cannot
be reassembled.
4. Be certain that ejector is locked in its lower (forward) position and that ham-
mer is in its fired (uncocked) position.
5. Replace slide onto frame.
6. Pull slide back until disassembly notch is opposite lug on slide stop. Press
slide stop all the way through the frame to the right.
7. Allow slide to move fully forward.
8. Replace empty magazine in frame through butt of pistol. This action returns
the ejector to its working position. This pistol will not function normally
unless the ejector is in its upward (rearward) position.
MAGAZINE INSPECTION AND CARE
Check the magazine frequently. The magazine follower must move freely and
have adequate tension so that each cartridge is quickly raised to the feeding posi-
tion. The magazine lips should be clean and free of cracks, dents, or nicks, so
that cartridges are held in their proper feeding position.
If the magazine becomes dirty, it should be disassembled and thoroughly
cleaned. You could encounter two types of Ruger magazines, with either a
pinned base or a snap-on base. The following disassembly instructions apply:
21
Always unload a firearm
before cleaning, lubrication,
disassembly or assembly.
UNLOAD BEFORE DISASSEMBLY
WARNING - DISASSEMBLY!
2
13 
						

							Pinned Base(used on 10 round 9mm magazines) - Use a punch to remove the
roll pin that extends through the side of the magazine body. Once the roll pin
has been removed, pull the magazine base from the bottom of the magazine
body, taking care to prevent the forcible ejection of the compressed magazine
spring. Withdraw the magazine spring from the magazine body. Turn the maga-
zine upside down and remove the follower.
Snap-On Base- Use a punch to press in on the magazine spring seat where it
protrudes into the hole in the magazine floorplate. Slide the magazine floorplate
toward the front of the magazine, taking care to prevent the forcible ejection of
the magazine spring seat and compressed magazine spring. Withdraw the maga-
zine spring seat and magazine spring from the magazine body. Turn magazine
upside down and remove magazine follower. Reassemble in reverse order.
When cleaning is necessary, use a solvent that will not rust the metal compo-
nents or adversely affect the magazine body. After the magazine has been soaked
to loosen foreign matter, be certain to shake it vigorously (with the loading open-
ing away from you) to remove solvent or residue from within the magazine.
Penetrating oils and solvents inside a magazine can “kill” or weaken cartridge
primers which can result in failures to fire or other possibly dangerous malfunc-
tions, such as leaving a bullet in the bore!
After cleaning always check to be certain that the magazine follower movement
and tension are correct, and that no solvent or debris remain. Improper reassem-
bly of the magazine spring can cause a potentially dangerous malfunction. If
cleaning does not restore proper tension, or if you experience a problem with the
magazine, don’t use it. Get a new one.
CARE AND CLEANING
Make Sure Gun Is Unloaded!
Before cleaning, be certain the pistol and its magazine contain no cartridges.
(See “Unloading Warning”, p. 15)
At regular intervals, or whenever the pistol has been exposed to sand, dust,
extreme humidity, condensation, immersion in water, or other adverse condi-
tions, disassemble, clean, and oil it. Proper periodic maintenance is essential to
the reliable functioning of any firearm.
To clean the pistol, proceed as follows:
1. Disassemble (fieldstrip) the pistol to the extent described on pages 19 - 21.
2. Using a cleaning rod, run a solvent-wetted patch through the bore several
times. Then attach a solvent-wetted bristle brush to the rod and run it back
and forth the full length of the bore as many times as necessary to remove
grease and dirt from the bore and chamber. Clean bore with dry patches and
examine. Bore fouling can contribute to reduced accuracy, and grease accu-
mulation in the chamber can interfere with proper feeding of cartridges from
the magazine.
22 
						

							3. Using powder solvent on a clean patch or bristle brush, remove powder
residue from all components of the mechanism. After cleaning, run a dry
patch through the bore, then follow with a patch that is very lightly oiled.
Wipe all surfaces clean with cloth, then wipe all surfaces with a patch or cloth
that has been very lightly oiled.
4.NOTE:Only a light application of oil is needed to provide adequate lubrica-
tion of moving parts and to prevent rust. Excess accumulations of oil tend to
attract particles of dust and dirt and may congeal in cold weather, which can
interfere with the safe and reliable function of the pistol.
5. Before firing, remove all oil and grease from the bore.
23
WARNING - LUBRICATION
IMPROPER LUBRICATION
DESTROYS GUNS
!
Firing a pistol with oil, grease, or any other material
even partially obstructing the bore may result in damage
to the pistol and serious injury to the shooter and those
nearby. Do not spray or apply lubricants directly on
ammunition. If the powder of a cartridge is affected by
the lubricant, it may not be ignited, but the primer fir-
ing may push the bullet into the bore where it may be
lodged. Firing a subsequent bullet into the obstructed
bore may damage the pistol and cause serious injury or
death to the shooter and those nearby.Use lubricants
properly. You are responsible for the proper care and
maintenance of your firearms.
STORAGE
GUNS SHOULD NOT BE STORED LOADED!
Do notkeep the pistol stored in a leather holster or case. Leather attracts mois-
ture, even though the holster or case may appear to be perfectly dry.
TO RENDER THE PISTOL INOPERATIVE FOR SAFE STORAGE
With the muzzle pointed in a safe direction, remove the magazine, retract the
slide, and check the chamber to be sur
e the pistol is completely unloaded! Keep
the muzzle pointed in a safe direction, and press upward on the slide stop. Insert
a finger into the action and press the ejector assembly fully forward. Next, pull
the slide stop pin out the left side of the pistol frame until it stops. Now remove
the slide and barrel assembly forward off the front of the frame.
USE THE LOCKING DEVICE SUPPLIED WITH THE PISTOL FOR STORAGE.
(SEEPAGE5) 
						

							24
Store the pistol’s frame and the barrel/slide assembly in different locations. When
disassembled in this manner, this pistol is inoperable. It is impossible to fire the
pistol until the barrel/slide assembly and frame have been correctly reassembled.
To reassemble the pistol for firing, carefully slide the barrel/slide assembly onto
the frame. Align the disassembly marks on the frame and slide, and then push
the slide stop pin fully into the receiver from the left. Either reinsert an empty
magazine or lock the slide open and push the ejector back upward and rearward
with a finger. The pistol is now reassembled and can be loaded and fired normal-
ly.
While the pistol is less likely to be used by unauthorized persons when disas-
sembled in the above manner, it is always safest to store any firearm with the
supplied locking device correctly installed, or to store the firearm in a gun safe
or other secure location away from children and unauthorized adults. Guns
should always be stored securely, unloaded
and separate from their ammuni-
tion.
Never place or store any firearm in
such a manner that it may be dis-
lodged. Firearms should always be
stored securely and unloaded, away
from children and careless adults. Use
the locking device originally supplied
with this firearm for storage.
The use of a locking device or safety
lock is only one aspect of responsible
firearms storage. For increased safety,
firearms should be stored unloaded and
locked in a location that is both sepa-
rate from their ammunition and inac-
cessible to children and any other
unauthorized person.
STORE SECURELY & UNLOADED

SERVICE AND PARTS POLICY
If you have any questions with regard to the performance of your RUGER®
P-SERIES pistol, please write or call (928)778-6555 our Product Service
Department in Prescott, Arizona, fully describing all circumstances and condi-
tions involved. If you should return your pistol to the factory for repair, or order
parts for it, please comply with the following suggestions for prompt service:
SIGHT ADJUSTMENT
The RUGER®P-SERIESPistols are equipped with a rear sight which is
adjustable for windage only. After the rear-sight lock screw has been loosened
(for those pistols equipped with a rear sight lock screw), the rear sight can be
drifted laterally in its dovetail on the top of the slide by tapping it with a wood-
en- or plastic-headed hammer or similar implement. Move the rear sight in the
direction you want the shot to move on the target. After the rear sight is adjust-
ed, tighten the rear-sight lock screw. The front sight is fixed. Both front and rear
sights are provided with white-dot inserts for rapid target acquisition and easy
alignment of the sights to obtain a correct sight picture.
