Feed speed: Adjusting the feed speed is done by turning the B1 valve. Clockwise decreases the speed. Coun-
terclockwise increases the speed.
Default setting: Close the valve and then open 3/4 turn.
Brake force: In order to maintain tension, the film roller is slowed down when being laid on the bale. Adjust-

decreases the brake force.
Default setting: Increase the pressure and notice the pressure on the manometer when the film breaks.
Then slightly decrease the pressure.
NOTE: When starting the machine cold, the brake pressure might be higher. Therefore, set the pressure by cold
oil or readjust when the oil temperature has increased.
Brake release valve: The brake is controlled electrically from the display unit or from the remote control on
the platform. See and section 3.6.4 "Remote control"
