Hill pull trouble

I have 1 problem stuck in my head, I made a routine adjustment 2 months ago from Atiker, they did not demand a fee, (we said it was 20 days since the tube was inserted) and now it is losing traction on the hill. Even though I am down, I fall down to 2 gears & nbsp; every morning I go 600m on average 45 degrees uphill & nbsp; is it normal or need to increase the gas slightly according to a friend? do they demand money? Do you have a friend who meets? Is there a problem with gas consumption? 1.6 engine

tried on gasoline losing traction later than the other, but 2500 revs can reach peak in 3rd gear. throttle falls to 1600 rpm in 3rd gear I have to drop to 2

speed and speed condition seems normal, there is no kidnapping in the press pad.
