5.
Rotate the pulleys by hand and check the alignment. If okay, assemble the protection
cover.
@ When the V-belts are worn, adjusting the tension wouldn’t help preventing the slip.
Replace the V-belts.
@ Do not overtighten the belts. Damage to the machine may appear.
13.2 REPOSITIONING THE HEAD.
The head is positioned in the main frame with two top guide rods 3 ( see Fig.8.) and two
bottom guide rods 7. All these rods have pivot eyes at their ends, which makes the head
extremely flexible.
Since the head is so flexible, the head should have a certain distance to the hopper. This
distance can be adjusted, within certain limits, as follows:
1.
When the head is fully down, the rubber seal 2 ( Fig.8.) may be against the hopper
edge 1. Adjust the length of top guide rod 3 to accomplish this. Adjust both sides the
same all the time. Next lock the rod with the two nuts 6.
2.
When the head is fully raised, the rear roller 4 ( in highest position) may not hit the
hopper 5. A clearance of 5 mm ( 5/16”) is required. This should be adjusted with the
bottom guide rod 7. Adjust both sides evenly and lock it with nuts 6.
After the adjustment has been carried out, check whether the head does not hit the main
frame at any place during its full stroke. If so, readjust the rods.
14.0 OPTIONS, SAFETY NOTES.
The main rotor can be equipped with several attachments, which are explained later.
Maintaining and exchanging items on the main and second rotor is done via the access door
25 of the head ( see Fig. 5). Some important notes:
•
The machine may never run without the access door correctly fitted.
•
When repair, maintenance is planned, the head should be firm on the ground, or
secured with D- shackle 13 ( Fig 5).
•
Be sure that the secure spring pins 1 ( Fig .9.) are correctly assembled.
•
If the lock pin 3 or the secure spring pin 1 is worn, they should be replaced
immediately.
•
Check that the brushes ( when mounted) are tightly fitted.
