McHale Fusion 3 Baler & Wrapper

10.4 Crop guard adjustment
The function of the crop guard plate is to hold down the baling material in order to
achieve an even flow of material. The height of the crop guard place can be adjusted
to suit the material type and volume, by means of adjusting the chain length.

10.5 Unblocking system
The McHale Fusion 3 is equipped with an unblock 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 and
push “Unblock” (Button 11) on the control box for three seconds, while in the Automatic
cycle. This will start the unblock routine and the knives, if set to ON, (see Section
“Electronic Control System” on page 58) will retract along with the channel floor. Then
restart the tractor PTO at a slow speed, increasing speed slowly up to 540 rpm and not
exceeding 610 rpm. Any lumps of material will now be easily transported into the bale
chamber.
After having cleared the blockage, a quick push of “reset” (Button 10) will return the
channel floor to the working position, followed by the knives, if previously set to ON.
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 pickup 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!
