Econo-Wrap EW-450A, Руководство оператора, Страница: 10 / 22

After making sure that the inclusion of the drive does not endanger the surroundings, can start wrapping
including hydraulic drive from the tractor cab. When wrapping, the tractor engine must maintain approximately
1500 rpm. Bale wrapping should occur after 24 (film 20” setting) or after 16 (film 30” settomg) rotations of
rotating frame (after about 1 minute of the wrapping). Fully wrapped the bale should have two layers of film, what
provides a fully leak-proof protection before the access of air and water. After wrapping, one should stop the
machine at the time when rotating frame with drums is in perpendicular position to the axle of the tractor and
the direction of travel. After unlocking the locking pin and lifting of bale wrapper on Three Point Hitch of tractor,
will occur the tilting of the lower frame and self-acting unloading the bale. Do not cut off the film prior to loading.
For the purpose of loading the next bale, one should lower of bale wrapper and lock the lower frame with the
locking pin. The drums must be set in the position as for first loading.
Recommendations for use
During operation of bale wrapper, special attention shall be paid to the technical condition and tension of
driving chains. After starting a new bale wrapper and after wrapping approx. the ten of bales, check tension
of driving chains, in particular of driving chain of rotating frame. To carry out the adjustment of the driving
chain of rotating frame, A)Remove Center Table Guard, B)Remove Gear Covers C) Rotate Bale Tray 90
degrees and D) Remove Front Frame Guard.
Once the chains are exposed, loosen the four nuts M12 (1) of the base of the hydraulic motor. Then, after
loosening the counter nut (2) screw in the bolt of chain tension (3) so that the deflection in the middle of the
longest segment of chain had about 20 mm.
After
the adjustment and control/inspection of the technical condition, lubricate the
chain with oil for driving chains.
