Question 1

How much stamina does it take to pump up this rifle with a hand pump?

Accepted Answer

I am 66 years old and weigh about 180 lbs. To pump it to 2500 psi is not too hard. From 2500 to 3000 takes a fair amount of effort. You will want to push down putting the handle at your belt line and come down with all your weight to get it to the bottom. You can do it, just saying that the effort is a lot more pronounced from 2500 to 3000. It takes about 90 pumps to go from 2000 to 3000 and about 50 pumps from 2500 to 3000. Don't pump more than 50 strokes at a time. Let the O-rings cool off otherwise you will melt the O-rings and then you will have to re-build the pump replacing the O-rings.When you do burn up the O-rings (and you will) you can order a re-build kit from Sun Optics USA (the makers of the pump) for about $6.00, you can look them up on the web. You can find directions for the procedure on youtube. Most people will tell you to lube the O-rings with silicon grease. Do not use silicon grease, use Nuvair 455, you can order it on the web from Nuvair Corporation. One quart will last forever and will work much better than silicon grease.I am not trying to talk you out of buying the pump. It is a well made pump that manages to compress a lot of air in a small amount of space. The weak link has always been the o-rings and I don't care whether you are talking about the Air Arms Pump or the Hill pump or the Benjamin pump ... they all have one thing I common ... they all use O-rings to seal the pump and all O-rings fail on high pressure pumps. Good luck and happy shooting

Question 2

I plan to store my rifle for about 6 months.  should i store it with air or without air?  thanks for taking the time to answer.

Accepted Answer

You should keep at least 1 bar,  1000lb in pressure canister for storage to keep from valve problems.
Use a good Air Ventura Hill Pump to limit moisture from the beginning to absorb moisture when pumping air.

Question 3

I fill it up to 3000 psi but in two days the pressure drops 2000psi. Is it normal for this gun or is my gun leaking?

Accepted Answer

It is normal with a PCP rifle to lose some pressure over the course of a couple days, however, this sounds different. For assistance, please call Benjamin Customer Service at 800-724-7486.
