When using the ring wrench to install the 
feedscrew, lift the feedscrew slightly while 
pushing it in.  

If the feedscrew does not slide up on the 
spline, it may be necessary to push down 
and in, while turning the feedscrew slightly 
to engage the drive spline.   B drives engage  
easier than the older A drives.  Never reach 
into the hopper to engage the drive spline.   
The feedscrew will jump in another inch 
when it is seated on the spline.  Check the 
head space!

3/4"

FEEDSCREW

HEAD

The head space should be checked on a 
weekly basis.  The head space is 3/4" on all 
DGI grinder units.  This should be done 
with the excluder seal removed.   Spacers 
should be added if the measurement is more 
than 3/4".  Spacers should be removed if 
less than 3/4". 

When using the ring wrench to install the 
feedscrew, lift the feedscrew slightly while 
pushing it in.  

NOTE:  THE FEEDSCREW 

SHOULD NEVER RUB THE HEAD
