Adjusting hop up:
Be sure to follow the manual's directions on how to adjust your hop up. Depending on your gun's velocity, you will need at least 30 yards of range to set your hop up. Try to achieve as flat a trajectory as possible.
Almost all Electric BBGuns have very sensitive hop up adjustments. A minute movement of the adjustment wheel or arm can cause large variations in BB trajectory.
Hop up mechanism can move and shift as the gun is being used. Expect to reset your hop up periodically.
Many factors can affect your gun's trajectory: cleanliness of the barrel, brand of BB, weight of BB, wind, humidity, and air density. Don't assume your gun will fire the same way anywhere, anytime, anywhen.
Cleaning airsoft guns:
*WARNING*: Never use petroleum lubricants or strong solvents and cleansers to clean your gun. Only use a soft, damp cloth to clean the exterior and 100% silicone oil spray to clean the barrel and lubricate the hopup. Maintenance on the internal gearbox mechanisms should only be performed by a trained professional. Do NOT soak the gun in any sort of lubricants or water. Liquids and electricity do not mix!
Electric BBGuns require minimal cleaning. The most important part that should be cleaned regularly is your barrel.
To clean your barrel, take your cleaning rod and thread a .22 caliber patch (or similar sized patch of cloth) through the slit. Spray a small amount of silicon spray to the patch.
Before inserting your cleaning rod into the barrel, turn your hop up off. If you leave your hop up on you run the risk of damaging your hop up and getting your cleaning rod stuck.
Insert your cleaning rod into the barrel. Swab the inside of the barrel with a back and forth motion. Remove the patch from your cleaning rod. Insert a new, dry patch into the slit and repeat the process to clear any remaining residue from the inner barrel.
Once there is no dirt left in the barrel, test fire your gun and reset the hop up (You may need to fire several hundred BB's before the hopup functions correctly after cleaning and lubrication, this is normal). We recommend you have your Automatic Electric Gun gearbox cleaned and relubricated every 6 months to a year, depending on how heavily your gun is used. This should be performed by a trained professional.

BB's:
Only use premium brand BBs with Automatic Electric BBGuns. Using cheaper BB's as found EBAY ECT may cause damage to your gun and barrel due to seams, burrs, deformation and inconsistencies in the BB's size resulting from poor manufacture.
*WARNING*: Do not reuse BBs. Reusing BB's may also cause a jam or breakage in your gun.
If you are not sure about what BB's to use, consult with bbguns support regarding what type of BB's to use.
Loading magazines:
Be sure to thoroughly read your manual on loading magazines.
Make sure your BB's are clean and new. Dirty or deformed BB's can cause your magazine or gun mechanisms to jam.
Keep foreign objects, debris, and dirt away from your BB's and your magazines.
Always remove and throw away the staple from your bag of BB's! They are notorious for jamming magazines.
Occasionally lubricate your magazines by spraying a small amount of 100% silicone lubricant into the magazine.
If your magazine has been subjected to significant amounts of dirt and dust, you will need to disassemble your magazine and clean out all of the dirt and dust, this should not be performed without prior experience.
High capacity magazines are fairly complex mechanisms.
In order for them to feed reliably, at least 50 BB's must be loaded in them.
There will always be some BB's left in the magazine.
A fully wound magazine will typically shoot 50%-75% of the magazine's full capacity before requiring rewinding.
You can overwind high capacity magazines, if the winding wheel is clicking, it is overwound. If a high capacity magazine jams, tap the side of the magazine sharply against a solid surface. That will unjam the winding wheel.
Unjamming airsoft guns:
BBguns typically jam due to excessive dirt in the barrel, dirty BB's, deformed BB's, foreign objects in the magazine or barrel, or overly tight hop up.
In more extreme cases, a gun can jam due to a damaged or deformed hop up bucking, damaged nozzle, or damaged tappet plate.
If a BB jams in the gun stop firing it immediately! Continued firing may result in a broken gear or piston.
Use the opposite end of your cleaning rod (The tip has a slanted angle) Turn your hop up off and insert that end into the barrel.
Turn the gun upside down to look at the magazine well.
Gently force the BB back into the area of the magazine well.
Once the BB's have been cleared from the barrel, test fire the gun without any BB's.
If the gun sounds fine, test fire it again with BB's.
If jamming persists, consult with bbgguns4less regarding repairs.
