Setting you velocity is simple, fire a few clearing shots then shoot you PRO-COMPv.3 over the chrono. If the velocity is to low slip a 3/16 hex wrench into the end of the cocking knob and engage it into the adjusting screw and turn it counter clockwise (note: some times the adjuster will be hard to turn if it has not been turned for some time, if you encounter this always turn the adjuster clockwise to free it up then counter clockwise.) If the velocity is to high turn adjuster clockwise to slow it down. Check the tuning of your velocity by removing the upper bolt after you get the velocity set where you want it and see how far open the air hole is open in the upper bolt. If it is almost completely closed the gun is over tuned and you should try turning the valve to the next smaller hole or try a stiffer valve spring, you will have to experiment with it to get the best performance and efficiency.

Always use a high quality light weight pneumatic oil, never use grease, heavy oil of oils with solvents in them. The proper oil is vital to good performance!

There are two ways lube your gun. The first way is to add a few drops of oil into the ASA adaptor before airing up (always cock gun before airing up) and shoot your gun about ten times, remove barrel before shooting to avoid depositing oil in it. This works good if you haven't cleaned your gun from the time you played. The second is to field strip the gun and wipe off old oil then put a thin coat on all moving parts and hammer O-ring. Field stripping and washing receiver and parts with warm soapy water, drying and lubricating is recommended periodically.

Proper maintenance will give your PRO-COMPv.3 a long trouble free life.
