McHale F5500 Baler

9.6 Unblocking system
The machine is equipped with an unblocking system. In the case of a blockage in the
feeding channel, the PTO overload clutch will disengage and a loud clicking noise will
be heard. Once this sound is heard, immediately turn off the tractor PTO. Push and
hold the drop floor diverter on the control box, while using the tractor pick-up spool lever
in the down direction, to lower the channel floor. (See the following image). Then restart
the tractor PTO at a slow speed, increasing speed slowly up to normal working speed.
Any lumps of material can now be easily transported into the bale chamber. (Note: The
knives will also be retracted when the floor is lowered and they will be reengaged when
the floor is raised.)
If a blockage occurs near bale completion, difficulty will be encountered in restarting
the PTO. The solution to overcome this, is to select Manual mode, then open the
chamber door a small amount so that the bale density gauge goes into the yellow zone.
(See ‘Bale density gauge’). Then restart the PTO and once the PTO is back up to
speed, close the chamber door fully and reselect Auto mode.
After having cleared the blockage, reset the channel floor closed, by pushing the drop
floor diverter on the control box, while using the tractor pick-up spool lever in the up
direction, to raise the channel floor back up into the working position. Baling can then
resume as normal.
Unblock mode, knives retracted and channel floor lowered
WARNING: Never go near the pick-up reel, while the reel is still
rotating and the tractor is running!
Never attempt to go near the pick-up reel while the reel is still rotating
and the tractor is running. In the rare case that the reel cannot be
unblocked using the procedure above, then the pick-up reel will require
manual unblocking, by removing the excess blocked material. To do this
safely ensure the PTO is disengaged, tractor shut down, key removed
and that all parts have stopped rotating. Also ensure machinery can’t roll
by parking machinery on level ground with the brakes applied and
wheels chocked. Remove excess material carefully. Always wear
protective clothing and gloves, beware of sharp edges!
