The ground control lever, however, when 
in automatic neutral position, should allow 
any forward or reversing creeping of the 
grinder (providing the grinder is on level 
ground, on unlevel ground, see disk brake 
control. Neutral position is adjusted by 
removing the quick disconnect from the 
control arm located on the bottom side of 
the transmission. Turn the socket in one 
complete turn in either forward of reverse 
position to adjust transmission onto 
neutral, more than one turn may be 
needed sometimes.
