HOW DO I CHANGE THE AMOUNT OF AIR SUCTION?
On every machine (except the Rotor) you can bend the flaps upwards to reduce their angle. This creates less air displacement, thus decreasing the amount of suction. You can bend the flaps downwards to increase their angle. This creates more air displacement thus increasing the amount of suction.
CAUTION: When bending the flaps downwards, make sure the flaps do not hit the metal wire brake line.
