Hi Malc,

Do you still have the original supplied handbook?

I think it shows you how to adjust the power - if you have no other problems then you do not need to take the pistol to a dealer.

If you are stuck, let me know and I will dig a TAU 7 handbook out and let you know how to adjust it yourself.

Hi Malc,

I have checked the Tau 7 handbook and the muzzle velocity can be adjusted by turning screw 20.

If you loosen and then slide the front wooden cover forwards, it exposes a large screw that faces towards the muzzle. This screw is usually held by two small grub screws, so these may need to be loosened before adjusting it and tightened again afterwards.

This should only take a few minutes to do and test to see if it fixes the problem for you.

Hope this helps - Bob.

I was just checking to see if Malc had fixed it himself without having to take his Tau to a dealer to repair it for him.

I was hoping a simple adjustment (as we mentioned) would solve his problems at no expense.

There are many dealers that can service this simple air pistol if a home fix does not work.

Yep Iam sure it would , however I have since discovered that one of the O rings at the breach had fallen out! and I somehow feel that this may, just possibly , how somthing to do with the problem Doh!

Yeah, this usually happens when the loading tray isnt shut properly and flies open with the shot..

I should not have laughed.

My son was shooting a TAU 7 last night ( and getting good scores too) - but the pistol was hissing from the breech all night and using plenty of gas, so it looks like we have to take a look inside and inspect the suspect valve!

The previous owner never used the gold coloured CO2 containers - only the cheapest possible types - and I am guesing the lack of any suitable lubricant has accelerated the valve seal wear?

Others TAU 7 owners that use the gold coloured cylinders from Walther/RWS etc or add a small blob of Pelgun oil to the tip of the cylinder before piercing seem to have less seal problems, so when we repair the leak/seal/valve I think we will use the gold cylinders from now onwards, or a spot of the new type of red Pelgun oil on the neck of the cheaper silver types.

I always used Crosman bulbs. Nowadays I'm using Umarex (cant find anymore crosman's). Never lubed any bulbs in the Tau's life. Never had a problem.
Tau 7's have been made from the 80's. Dunno how old yrs is, but they ALL start leaking 1 day. Seals arent made to last forever.
Tau used quite hard seals ex factory on their newest models(iirc, white one's). Together with the softish hammer spring, this makes for suburb co2 adjustability (for varying temperature etc) but it also enlarges the chance of a leakage. Lateron, they got softer blue one's. Also, its quite often caused (leakages) by dirt/oil between the valveseal. Too much oil or the wrong one can cáuse leakages.
In yr case, change the valveseal (screw in a bolt or anything into it to pull it out). Or you could try to tap it(valve), to reseal/reseat it.(often helps with the many leaky NEW Tau's )
