1 Trigger weight
Adjusting the trigger weight by means of adjusting screw [6]:
 
y turn clockwise = trigger weight is increased (+)
 
y turn anticlockwise = trigger weight is reduced (–)
The trigger and first stage weights are mechanically interdependent. Any adjust-
ment always results in a small concurrent change in the  
trigger or first stage weight.
Moving the trigger cam  
y lowest setting of the cam = least trigger weight
 
y highest setting of the cam = highest trigger weight
A 2 mm Allen key and maybe tweezers will be 
needed to adjust the trigger cam.
NOTE!
 
y turn anticlockwise = loosen fixing screw
 
y turn clockwise = tighten fixing screw
After the trigger cam has been moved it will be necessary to check  
the sear engagement (according to the subsection "Sear engagement") and 
readjust it if necessary.
Fine adjustments are made to the trigger and first stage weights  
by means of adjusting screws [6] (trigger weight) and [5] (first stage weight).
Material damage! Risk of fracturing the clamping screw with too high  
a torque.  
h Ensure that the trigger cam is correctly seated.
CAUTION!
22     
						

							Setting the optimum sear engagement: 
I The rifle must be unloaded.
 
X Cock the rifle and release the trigger (check whether the trigger releases 
as desired).
If the sear engagement is too long:
There is a short travel from the second stage to the release of the trigger (so-
called "pull" or "tug").  
X After cocking and releasing the trigger, turn adjusting screw [2] clockwise 
in steps (approx. 
1/8 turn each time).
 
X Repeat the procedure until the second stage is no longer  
perceptible.
 
X Then turn back 
1/5 turn anticlockwise.
 
9 The optimum sear engagement is now set.
If the sear engagement is too short:
There is no longer any second stage. The trigger releases indefinably without a 
second stage.  
X After cocking, turn the adjusting screw [2] at least 
1/4 turn  
anticlockwise, release the trigger and check whether  
there is a second stage.
 
X If not, repeat the procedure until there is a perceptible second stage.
 
X As soon as there is a perceptible second stage, proceed according to the 
subsection "If the sear engagement is too long" to achieve the optimum 
sear engagement.
To set the sear engagement with a single-stage trigger using adjusting screw 
[2],  see Point 7.
2 First stage weight (only with two-stage triggers)
Adjusting the first stage weight by means of adjusting screw [5]:
 
y turn clockwise = first stage weight is increased (+)
 
y turn anticlockwise = first stage weight is reduced (–)
The trigger and first stage weights are mechanically interdependent. Any adjust-
ment always results in a small concurrent change in the  
trigger or first stage weight.
3 Sear engagement
The sear engagement denotes the travel from the second stage to the release 
of the trigger.
Danger to life!
Unintentional discharge as a result of too short a sear en-
gagement and/or too low a trigger weight.  
h Do not set the sear engagement too short.
 
h Do not set the trigger weight too low.
 
h Do not subject loaded and unsecured rifles to  
impact and do not use force to close the breech.
WARNING!
Adjusting the sear engagement on a two-stage trigger by means  
of adjusting screw [2]:  
y turn clockwise = sear engagement is shortened
 
y turn anticlockwise = sear engagement is lengthened
23     
						

							4 First stage travel (only with two-stage triggers)
First stage travel denotes the travel of the trigger blade from the zero position to 
the second stage.
Setting the first stage travel by means of adjusting screw [1]: 
y turn clockwise = first stage travel is shortened
 
y turn anticlockwise = first stage travel is lengthened
Danger to life!
The first stage travel adjusting screw is set beyond the second 
stage function.
 
h Never turn the first stage travel adjusting screw beyond 
the second stage function.
 
h Never remove the first stage travel completely in order to 
convert the two-stage trigger to a single stage trigger.
WARNING! 5 Trigger stop
The trigger stop denotes the travel from the second stage to the end stop for the 
trigger blade.
Setting the trigger stop by means of the trigger stop adjusting screw [4]:
 
y turn clockwise = trigger stop is shortened
 
y turn anticlockwise = trigger stop is lengthened
Malfunction!
Trigger stop adjusting screw has been turned beyond the 
actuation point (trigger does not actuate).
 
h Do not turn the trigger stop adjusting screw in  
beyond the actuation point.
CAUTION!
6 Moving the trigger blade
Release clamping screw [3]. The trigger blade can both be moved along the 
guide and also pivoted to the side.
24     
						

							7 Converting a two-stage trigger to a single stage trigger
Adjustments: 
y Turn the screw for the first stage travel [1] anticlockwise until the maximum 
first stage length has been set.
 
y Cock
 
y Turn adjusting screw [2] (second stage) antickockwise until the  
trigger releases.
 
y From this setting, turn adjusting screw [2] approx. 
1/4 turn  
clockwise.
 
9 The trigger is now adjusted for single stage; there is no longer  
any first stage travel.
Danger to life from automatic firing!
Automatically firing shots and malfunctions caused by mini-
mally set trigger weight and too short a sear engagement.
 
h Do not set the trigger weight too low.
 
h Do not set the sear engagement too short.
WARNING! 8 Converting a single stage trigger to a two-stage trigger
 
y Turn the trigger stop adjusting screw [4] approx. 2  
1/2 turns  
anticlockwise (set the max. trigger stop longer).
 
y Release the safety catch and cock the rifle.
 
y Turn adjusting screw [2] clockwise by approx. 2  
1/2 turns.
 
9 The second stage is now perceptible.
 
I To set the optimum sear engagement, the procedure in Chapter 3  
("Setting the optimum sear engagement") must be followed.
 
X If required, the trigger characteristics can be set to the desired  
values as follows: first stage travel per Point 4, trigger stop per Point 5, trig-
ger weight per Point 1 and first stage weight per  
Point 2.
9 Trigger malfunctions caused by misadjustment
Proceed as follows in the event of malfunctions caused  
by a misadjusted trigger:  
X The trigger function must be checked after every change.
 
X When the malfunction has been rectified, check the desired trigger charac-
teristic and adjust it again if necessary.
The trigger catches the firing pin but does not fire when pulled:  
y Check whether the safety catch is engaged.
 
y Check that the trigger cam [7] is present and screwed on correctly.
 
y The trigger stop adjusting screw [4] is screwed in a few turns too far (turn 
screw [4] anticlockwise by a few turns until the firing pin [8] releases once 
more when the trigger is pulled).
25     
						

							The trigger does not catch the firing pin: 
y Adjustiing screw [1] (first stage) is screwed in several turns too far.
 
y Check that the tension spring is not damaged and is fitted correctly.
The single stage trigger is set too tight:  
y Turn adjusting screw [2] clockwise in 
1/4 turn steps until the firing pin [8] is 
caught.
The catch link return spring is too weak or is defective:  
y The trigger must be returned to the factory for repair.
18 Dry firing device 
The length of the firing pin is factory-adjusted to ensure that the  
cartridge detonates reliably. Long periods of dry firing without a  
cartridge or a case in the chamber can cause damage to the firing  
pin or the rim of the chamber. For this reason, either a spent cartridge case 
(replace approx. every 5 shots) or a damping disc (1927F-40) should always 
be used.
With this device, match training can be carried out at any time  
without the use of ammunition.
Installation
 
X Remove the bolt [2] (see Chapter 13).
 
X Unscrew the connecting nut [c].
 
X Withdraw the bolt body [d] from the rear part of the bolt.
 
X Fit the damping disc [b] on the firing pin [a].
 
X Screw the bolt body [d] and the rear part of the bolt together evenly by 
means of the connecting nut [c].
 
X Cock the bolt [2] and commence use.
 
I The damping disc must be removed again before a competition.

							19 Maintenance/cleaning
19.1  General 
Danger to life!
Danger to life from loaded firearm.
 
h Ensure that the rifle is unloaded before use or  
during maintenance and cleaning work.
WARNING!
Injury and material damage!
Danger of injury or material damage as a result of  
not removing the oil from the barrel and chamber.
 
h Each time before shooting, any oil or foreign objects must 
be removed from the barrel and chamber.
CAUTION!
The rifle should be protected from dust, sand,  
moisture, heat and damaging influences.
NOTE!
After each use of the rifle, apply a thin film of oil 
to the steel parts and thoroughly clean the barrel.
When the rifle is transported from cold to warm 
rooms, condensation can form on the metal 
parts and inside the barrel. If this condensation 
is not quickly dried off, it can possibly lead to 
surface rust. Cleaning the synthetic parts (e.g. 
magazine butt plates, follower) only with oil 
which do not damage, attack or decompose  
the synthetic material!
NOTE!
The rifle case / soft case should be cleaned regu-
larly and any dust and fluff removed.
Rifle cases and soft cases should have a smooth, 
dust-repellent lining.
When not in use, the rifle case / soft case should 
always be left open to allow moisture to escape.   
Enclosing a desiccant can reduce the moisture  
content.
NOTE!
To reduce the risk of breaking the stock during  
transport, ANSCHÜTZ recommends separating 
the barrelled  action from the stock, especially 
during air travel.
NOTE!
27     
						

							Always look out for any changes or damage 
that may occur to the rifle.
In the event of a change or damage, the rifle 
must immediately be taken to an authorised 
gunsmith or sent to ANSCHÜTZ for inspection.
CAUTION!19.2 Cleaning the barrel
If the barrel is only slightly dirty, use a plastic brush to clean it.
 
X Lightly oil the plastic brush and push it through the barrel from  
the cartridge chamber end with a suitable cleaning rod.
Fig.26 Plastic brush
If the barrel is very dirty, use a bronze brush together with a suitable barrel 
cleaner.
Pay attention to the user instructions for the 
cleaner!
NOTE!
Fig.27 Bronze brush
 
X Pull a woollen swab through the barrel several times to dry it.
It is essential to re-oil the barrel after using 
ammonia-containing cleaning agents, to avoid 
the risk of corrosion. 
NOTE!
28     
						

							19.3 Maintenance intervals
Pay attention to the instructions supplied with 
the cleaner.
NOTE!
Before shooting  
y Carefully remove any oil from the rifle.
 
I The de-oiling of the rifle should be carried out at room temperature, as too many residues can be left 
in the barrel if it is very cold.
After shooting  
y Pass a dry brush through the barrel (to remove powder residues).
 
y Do not bring the rifle into warm rooms with the bolt locked and  
the snow cover closed (condensation).
After the competition  
y Allow the rifle to warm up to room temperature with the breech  
and the snow cover opened.
 
y Carefully remove condensate from the outside parts.
 
y Dismantle the bolt action (see Chapter 14) and likewise remove  
the condensate from the individual parts.
 
y Oil the rifle (including the stock) with a suitable gun oil.
 
y Clean the barrel with a plastic brush and gun oil.
 
y Cleaning the synthetic parts (e.g. magazine butt plates, follower)  
only with oil which do not damage, attack or decompose the  
synthetic material!
If very dirty  
y Clean the barrel with a bronze brush and a suitable barrel cleaner.
 
y Wipe the rifle (including the stock) with an oily rag.
Yearly  
y Take the rifle to a dealer/gunsmith for inspection.
19.4  Trigger maintenance 
 
y Lubricate the pivot bearing once a year with a thin,  
low-temperature oil.
 
y Dab a small quantity of oil between the bearing parts with a    needle.
 
y To avoid gumming, adhesion or soiling of the trigger parts,  
never wash out the inner parts of the trigger with a spray or oil.
 
I No dirt, solvent residues, grease or unsuitable oils must get into the trigger assembly  
during maintenance of the rifle. ANSCHÜTZ recommends cleaning the rifle on its side  
or with the stock pointing upwards, which will prevent any adverse effects on the  
trigger assembly.
19.5  Maintenance of the optical sights 
The ANSCHÜTZ rear sight is a precision unit and 
consequently requires the utmost care when  
handling. 
Intensive care and maintenance guarantee per -
fect function.
The rear sight must be protected from dust and 
dirt.
Spindles must not be oiled or greased.
NOTE!
29     
						

							20 Optical sights
Operating and maintenance instructions can be 
found in the individual manufacturer's documen-
tation.
NOTE!
20.1  Mounting 
The rear sight is slid on to the 11 mm wide V-block rails and locked in a suitable 
position using the 2 clamping screws (just tighten hand-tight).
20.2 Elevation and windage adjustment 
The elevation and windage adjusting screws have click stops. The position of 
the aiming point is moved from click to click.
 
y Elevation when shooting high = turn rotary knob in "H" direction
 
y Elevation when shooting low = turn rotary knob in "T" direction
 
y Windage when shooting to the right = turn rotary knob in "R"      direction
 
y Windage when shooting to the left = turn rotary knob in "L"         direction
20.3  Zero adjustment 
After the sights have been zeroed, the two adjusting screws can be set to the 
"0" position.
 
X Release the set screws in the rotary knob.
 
X Position the rotary knobs to "0" on the scale.
 
X Tighten the set screws in the rotary knob hand-tight.
 
I The ANSCHÜTZ rear sight is aligned with zero clearance at the factory and does not require further 
adjustment. For this reason only the elevation and windage screws may be operated.
 
I Do not turn the knobs beyond the stops at the end of the adjustment travel  
(the pre-tensioned threaded drive can be damaged).
21 Troubleshooting
In the event of malfunctions (e.g. shots not di-
scharged, etc.) the rifle must be unloaded, se-
cured and taken without delay to a specialist 
dealer/gunsmith or sent to ANSCHÜTZ.
