Attach the filler device to your rifle in the manufacturers handbook.NOTE: Before starting to fill your rifle consult the rifles manufacturers handbook to ascertain the correct fill pressure.2-Check that the Bleed Valve Screw is fully in and tightened up.3-Place your feet on the pumps base plate, this ensures a stable platform whilst pumping.4-With the rifle placed on a mat and no kinks in the hose, begin pumping. Raise the handle upwards and press down to force air into the rifle. The most efficient way of pumping is to use the momentum of the upward stroke and your own body weight to push the handle down on the downward stroke.5-Continue pumping until the desired fill pressure is reached. Unscrew the Bleed Valve Screw and release the air still in the pump and hose. The Bleed Valve screw is situated underneath the Pressure Gauge. There will be an escape of air, this is perfectly normal and is simply the air venting from the pump body and the hose. By bleeding the system pressure is lowered in the connectors making them easier to detach from the rifle.WARNING:NEVER try to disconnect the filler device from the rifle whilst the system is still pressurised as this can lead to accidents and injury to the person and damage the rifle.NEVER put your hands anywhere near the Air Release Hole at the base of the pump when unscrewing the Bleed Valve Screw.

If for any reason it does not function correctly, consult the ATTENTION of the manual. If the symptoms still persist or you cannot find a solution via the trouble shooting guide call the dealer.NEVER use this pump to fill any vessel that has not been fully tested.ATTENTION:When you start pumping the gauge does not move. Please check that the bleed valve has been fully tightened up. Air could be leaking out through the air vent hole.When you pump the gun up and then release the air from the pump,a large amount of air comes hissing out. This could be one of two things, depending on the amount of air escaping. You get a small volume of air escaping when you bleed the system, this is perfectly normal and is necessary for the safe working of the pump. If the volume appears excessive then the problem could well lie with the rifle or vessel being charged and its non return valve not operating correctly. Try the pump on a different vessel, ifthe problem persists there is a fault with the pump and you should return it to your dealer for repair, if the problem does not manifest itself the fault lies with the rifle or vessel and these should be dealt with as outlined in their own user instructions.
