Ernie,

You won't have any problem jacking the nose and working the nose gear with the pump... just pull the breaker before the nose gear completely retracts. The hydraulic pressure isn't going to get switched to the mains until the nose gear is all the way up. Once you've pulled the breaker on it, then you can freely move the nose gear up into the wheel well all the way if you like by hand. When you're ready to put it back down, move the gear handle to the down position and then push the breaker in. Pretty simple, but as GMAs says, you don't want to be putting a strain on the motor/pump, so just don't let it go all the way... when it kicks up, and it will happen pretty fast... pull the breaker.

Hope this helps... BTW, we've done this a few times and you're not going to break anything... but DO make sure the jackpoint is secure on the jack... and make sure the nose wheel is off the floor... you don't want the nose gear kicking up and causing the airplane to 'roll' and cause it to fall off the jack. Just be cautious and careful. And block the mains so in case the nosewheel isn't off the ground it won't cause the plane to move.
