Warnings and Important Safety Guidelines

Warning! The Excalibur paintball marker is not a toy!

Careless or improper use, including failure to follow

instructions contained within this manual, may result in

injury or death.

Read Operator’s Manual before use and comply with all

safety instructions. Do not fire this, or any marker, at a

person when at a close range. Observe all local laws,

regulations, and ordnances when using this marker. Use

only at paintball fields where safety codes are strictly

enforced.

You must be at least 18 years of age to purchase this

marker. Users under the age of 18 must do so only

under adult supervision. Use only bottles approved for

Nitrogen, compressed air, or CO2. Make sure all bottles

are hydro-tested according to DOT regulations.

Use only .68 caliber paintballs in this marker. Do not

attempt to fire foreign objects from this marker. Use an

approved barrel blocking device when your marker is

not in use. Always disconnect air source and switch off

power source when not in use. Never shoot at velocities

in excess of 300 FPS. Never put your fingers or foreign

objects in the feed tube of the marker.

Never expose battery to open flame or heat source.

When connecting or disconnecting the battery, take care

not to short out the battery.

Always wear eye protection when adjusting, servicing,

or using your marker. When doing any work to your

maker, make sure the power and air source have been

disconnected. Be sure all paintballs have been

removed. Seek professional assistance if you unsure

of anything.

Introduction This manual is a work in progress and will be continously updated as needed. If you see an area that needs work, contact us thru e-mail and let us know. If you have sugestions or a different method of doing something that pertains to the Excalibur and its components, write us with your suggestions. We decided to place the manual on disk for the simplicty of keeping it up to date and to eliminate paper waste.
PAGE 3
Power Source The Excalibur(tm)(pat pend) uses a 9-volt battery stored in the grip as its power supply. For maximum number of shots and velocity stability you should only use high capacity rechargeable batteries or lithium batteries. The Excalibur’s(tm)(pat pend) circuit board is designed with a special voltage regulator system to allow the use standard alkaline batteries. For best performance it is still better to use rechargeable or lithium batteries.
PAGE 4
Excalibur Notes AKALMP is continuosly refining the Excalibur to push its performance to the extreme. Here is a list of things that have changed between the different batchs of markers. This manual covers most things on the Excalibur but be careful becuase there may be a change that is not in this version of the manual yet. AKALMP reserves the right to revise and improve its products as it sees fit. Serial numbers: 0 thru 57. These are original production units.
PAGE 5
Cleaning and Maintenance The barrel on the Excalibur(tm)(pat pend) can be cleaned during a game by either unscrewing the barrel from the marker or by removing the bolt and swabbing through the marker and the barrel. Every 50,000 cycles or 6 months: Inspect, and replace if needed, the Ram and hammer orings. Inspect the regulator seat on the pneumatics regulator and the Sidewinder(tm)(pat pend) regulator for wear.

Troubleshooting Is the battery fresh and new? - See Power Supply. Excalibur(tm)(pat pend) will not fire Is there a battery in the Excalibur(tm)(pat pend)? - See Power Supply. Is there air/nitrogen or CO2 gas present? - See Air Supply. Was the compressed air or nitrogen clean? Is the Excalibur(tm)(pat pend) turned on? - See Power Supply. Is the trigger adjusted correctly? - See Trigger Adjustment. Firing too slow Is your rate of fire (ROF) set correctly? - See Electronics.

Custom Work For the customers that want splash, custom color anodizing and have custom mill work, there are versions of the Excalibur(tm)(pat pend) available through our authorized airsmiths that can be made into custom markers. These markers are still covered under factory warranty if the work is done by an authorized airsmith. AKALMP will be doing a limited number of custom Excaliburs. A complete list of our authorized airsmiths can be found on our web site, akalmp.com.

Electronics The Excalibur(tm)(pat pend) is controlled by a state of the art software driven computer board. The newer design runs the Excalibur(tm)(pat pend) at its true fire rate capability unlike the original circuit board in the first 40 Excaliburs(tm)(pat pend). The board is equipped with many features that are not found on other electronic paintball markers. First the board is equipped with a special voltage regulator system that will increase the life span of the battery.

Excalibur(tm)(pat pend). You can change these numbers directly or set them and then change the rate of fire control. Dwell adjustments: To change the firing parameters of the Excalibur(tm)(pat pend), first make sure the marker is unloaded, degassed and turned off. Plug the programmer cable into your computer. Then remove the cover plate on the left side of the grip plate. Gently plug the cable into the connector on the circuit board. Load the manual and start the “parameters adjusting” program.
PAGE 10
Hammer Mechanical Hammer adjustment: There is no mechanical adjustment to the hammer itself. Simply screw the hammer cartridge in until it stops against the body. Hammer maintenace: The o-ring on the hammer piston is sized to maintain a constant fricton to the inside of the bore of the hammer cartridge. Keeping a constant fricton on the bore is important to keep a consistent velocity.
PAGE 11
push the bolt pull pin down until it latches into the Hbar. tube you can order one from your local airmsith or from AKALMP. The screw in the back of the bolt adjusts the tension and locking of the bolt pull pin. You should not have to adjust this. But, if you do, adjust the ball plunger in until you cannot pull the bolt pull pin up. Then slowly back it off until the pin moves at the desired tension. Do not adjust the tension too far out or the pin can come loose.
PAGE 12
The pneumatics regulator controls the air pressure fed to the solenoid valves, which in turn operate the rest of the gun. The maximum operating pressure of the solenoid valves is 120 psi., but the components of the Excalibur(tm)(pat pend) need only 90-100 psi to operate. Use of the pneumatics regulator keeps the solenoid valves from receiving too high a pressure, and will keep them operating properly for many years.
PAGE 13
Pneumatic Ram Removal of Pneumatic Cyclinder (ie: the Ram): De-gas the marker and remove all paint. Remove the bolt, the body endcap, and pneumatics regulator. Then remove the set screw pin that holds the ram in place. Using a 1/2" dia wood dowel rod, gently push the ram out through the back of the marker body. Disassembly. Screws and O-Rings Insert a 1/4" dia metal rod in the set screw pin hole. You may have to polish the 1/4" rod just a little to get it to fit properly.

PAGE 15
Dead Zone: Since the Sidewinder(tm)(pat pend) regulator was designed to go down to zero psi output, there is space after it reaches zero that the adjuster screw can be turned farther. If you turn the adjuster screw gently until it bottoms out, then it will be 4 to 5 turns counter clockwise until the pressure starts to rise again. This is the dead zone.
PAGE 16
Solenoid Valves Trigger Frame Removal of the solenoid valves: Adjusting the trigger pull: Remove the grip frame and grip plate as one piece. Carefully pull the grip and grip plate straight away from the body. The grip plate locates on two pins in the marker body. There are 3 set screws for adjusting the total trigger movement: (1) forward stop, (1) rearward stop and (1) mirco-switch activation screw. Carefully unplug the solenoid valves from the circuit board.
