TIP: Too little hammer energy at high fill pressures may result in very low velocities which is the result of partial valve lock.
See the Overfill section (3C) to correct. Make only the adjustments identified in this manual. Do not attempt to adjust any
other parts of a pressurized airgun, or make any repairs to a pressurized airgun.
Tuning the air rifle to obtain various velocity profiles can be achieved through the adjustment of the hammer spring and
the striker and should be done in harmony with each other. Start slow to understand how each one affects the air rifle’s
performance. Experience and testing is the best way to understand these capabilities.
do Not attempt to repair the airguN or to disassemble to correct aN over fill or valve lock. Never
repair a pressurized guN. parts caN fly from the airguN at daNgerous speeds WheN it is disassembled While pressurized.
C. Tuning for Various Velocities
The Marauder air rifle has been factory set to an efficient
velocity that will suit most hunting and target uses. If you, as
the owner, wish to alter the factory settings you should do so
only after reading the following instructions carefully. Unless
you are experienced with working with airguns, Crosman
Corporation suggests seeking the aid of a qualified gunsmith
to perform these velocity adjustment procedures.
Put the air rifle “ON SAFE”, remove the clip and keep the airgun
pointed in a SAFE DIRECTION. Remember that the airgun is
pressurized and make only the adjustments identified in
this manual.
The Marauder may be tuned for various velocities by adjusting the valve
metering screw. This will require removal of the stock. Remove the stock screws
(Fig 12) (using a 3/16” Allen wrench) to separate the stock from the action.
Remember the action is pressurized. Keep it pointed in a safe direction.
Do not remove the trigger guard screws as the trigger guard should remain with
the stock.
Using a 5/64” Allen wrench, remove the jam set screw first to allow access to
the metering screw. (fig 13) (Be sure to stow the jam set screw in a safe place).
Find the metering screw beneath the jam set screw previously removed. Using
a 5/64” Allen wrench turn the metering screw clockwise to restrict the flow of air
into the barrel and reduce the pellet velocity.
TIP: Turn the metering screw in all the way until it bottoms, counting how many turns it took to achieve the desired velocity.
Record this value for future reference. 4 - 41/2 turns out from the bottomed position will completely clear the nose of the
metering screw from the air path. Do not adjust the metering screw beyond this point. Though the metering screw will
restrict air flow a great deal it will not completely shut off air flow. For use with CO
2
it is recommended to use a more open
setting (metering screw out to clear air path)
Replace and tighten the jam screw. Re-insert the action into the stock, and replace and tighten the stock screw.

Changing the Bolt Direction
The bolt direction on your PCP rifle is capable of being changed to the opposite hand. The rifle is factory assembled with
the bolt handle pointing to the right. Disassembly of the Breech and Barrel assembly from the Reservoir Tube assembly
is required to access the parts contained within the Breech that facilitate the change to the opposite hand. Crosman
Corporation recommends the use of an approved Service Station to perform the change. An approved Service Station may be
found through www.crosman.com or by calling Customer Service at 1-800-724-7486.
13. Adjustable Comb
The stock comb may be adjusted up and down to suit the shooter’s preference.
To adjust, loosen the two set screws shown in figure 14 using a 3/32”allen
wrench. Move the comb up or down then retighten the set screws gently first
and trial the change. After a satisfactory position is found tighten the set screws
an additional 1/8 turn to ensure the comb does not slip during use. Do not over
tighten the set screws or permanent damage could occur to the stock.

This airgun has been classified as an adult airgun, and is recommended for adult use only. Because it is considered to be a special-purpose airgun, it is
exempt from specific types of trigger pull, safety mechanism and drop tests.

PERFORMANCE
Many factors affect velocity, including brand of projectile and weight of projectile.
Your Marauder has been designed for quiet shooting. However when using light weight pellets the sound barrier may be
broken resulting in a loud muzzle report.
