Inserting Needles 

 

Your machine came equipped with a set of needles.  Each needle has qualities 
that are more suited to different types of seed.  Below are some examples of 
seeds and the needles you should use for each.  Use this as a general guide to 
help determine the proper needle for the seed you are sowing.  If you have 
questions, or need another needle size, please contact us.

Before you insert the needles, select the tray you are going to use to sow.  Adjust 
the front and rear slide rails to fit the tray width (if necessary).  To adjust the slide 
rails, unlock the left and right handles, slide the rail to the desired width, then 
relock the handles.  Insert the tray into the machine far enough so that the tray 
slides under the drop tube bar.  If necessary, replace the drop tube bar to match 
the tray you are using (see next chapter for instructions to replace drop tube bar).  
Having the tray in place will aid you in correctly placing the needles into the 
proper slots to match the holes to the cells. 
 
Insert needles into the tip on the needle bar and turn clockwise until secured.  Do 
not over tighten as this can damage the tip.  Place needles in tips to align to the 
cells in the tray you are planting.  You may not fit needles into all the needle tips.  
Your needle kit came complete with a set of blank needles, and you should insert 
these in the same fashion into tips that do not align to cells in your tray. 
 

IMPORTANT NOTE: 

 Make sure to place the lavender “blanks” into any needle 

tip that does not have a needle in it.  Failure to do so will create negative vacuum 
through the empty tips and you will not pick up seed with your needles.
