By turning the valve clockwise, the ow is reduced and therefore the speed. The opposite occurs
when turning the valve counter clockwise.
Valve 50 is controlling the total ow to the wrapper. If the valve is turned clockwise, the total oil volume will
decrease and all the movements in wrapper unit will be slower.
Valve 51 is controlling the amount of oil to the wrapper arm. If the valve is turned clockwise the arm speed is
reduced.
Close the valve nr.50, then open 3/4 turn (basic seng). Close valve nr. 51 completely, then open gradually
unl correct speed on the arm is achieved. Maximum 25 RPM. Adjust the speed on the belt with valve 50, to
correspond, the rotaon of arm and overlap of lm layers.
Aer the fast speed is correctly adjusted, the slow speed must be set. By turning valve nr. 69 adjust and set
the slow speed to maximum 10 RPM.
The slow speed must be correctly adjusted to ensure the lm cuer is working properly. The speed
will increase when the oil is warm. Observe the wrapper arm carefully and adjust the slow speed once again
if necessary.
The rise and lowering speed of the arms must be correctly set. If the speed is too high, the lm is torn in-
stead of a controlled cut. The speed of knife arms is adjusted by turning valve nr. 53 (right arm), and valve nr.
54 (le arm) The speed is reduced by turning clockwise.
Both sides need to be adjusted equally, the arms should have a smooth moon, and not slammer.
Close the valve, then open 1/2 turn.
By adjusng the wrapper lt -speed, we can change the bale drop speed. By turning valve nr. 52 clock wise,
the drop speed will increase. To avoid the risk of uncontrolled unloading of bale, the drop speed shouldn't
be set to fast.
Close valve, then open 3/4 turn..
