2. Instead of pinning the quilt top to the pick up leader it is basted to the backing and batting Because the quilt top is floating on top of the batting and backing and away from the leader you are free to stitch right off the edge of the quilt top The opposite edge of the quilt top is pinned to the top roller or you may choose to completely float the top If you have a quilt top with irregular edges such as Grandmothers Flower Garden or Double Wedding Ring floating the top makes loading the quilt easy In the instructions that follow we will use the pick up roller to help hold the top and backing as we load the quilt The quilt top is loaded first then the backing and finally the batting As you read through the instructions you can choose which method to use to load your quilt If you plan to float the top completely without pinning any edge to the top roller start the instructions at Load the Backing below Load the Top Roller 1 The quilt top is loaded first Find the center of the long edge and mark it with a pin From the back of the machine lay the quilt top right side up over the pick up roller with the marked edge facing front omooth out the quilt top along the pick up roller and let it drape over the table and onto the floor The pick up roller helps keep the top flat as you pin and or roll it onto the top roller N N N SS N N N N N S

6. Check the location of the seam and check to see if the design is directional so the top of the quilt is the same on both sides Backing seams that are perpendicular to the rollers may form puckers To prevent this always check the backing seam by running your hand against the back of the quilt after advancing the quilt A backing seem that was not properly pressed tends to form pleats along the seam You can smooth out any excess fabric and clamp the sides to keep the backing flat If the backing seam is parallel to the rollers then the tension of the layers between the rollers is generally enough to smooth out any puckers along the seam line Batting Your quilting machine is capable of stitching through a variety of batting materials and thicknesses Always choose batting that is recommended for machine quilting Battings made for hand quilting are generally thinner and are difficult to work with on the quilting machine Packaged battings will have areas that are stretched out a little from the folding and should be fluffed in the dryer before loading onto the quilt Head the manufacturers instructions for proper care Open the package unfold the batting completely and toss it in the dryer along with a damp wash cloth for a little moisture Tumble for 10 to 15 minutes The batting will now lay flat in the machine Batting that is stored on a roll generally does not need to be fluffed before use Determine Loading Direc

12. To make finer adjustments in height and or to level the table there is a level adjustment at the bottom of the leg Turn the level adjuster until the desired height is reached To help make adjusting the height easier use small car jacks on each side to raise the table to the proper height Be sure that the jacks are stable and then adjust the height adjustment and leveling screws to the height of the jacks Carefully remove the jacks after the adjustments are made Parking the Sewing Head As you are servicing or cleaning the sewing head you want it to remain still As you load unload a quilt you want the sewing head to be out of the way The back of the carriage includes two outer and two inner wheels The carriage rides on the outer wheels while the inner wheels do not touch the carriage To park the sewing head at either side of the table the outer wheel rides completely off the track while the neighboring inner wheel catches the track Note Parking the sewing head can only be done when the pick up roller is installed inside the sewing head throat If the pick up roller is not installed the sewing head could roll backwards and fall off the table 3 Supplies Spare Parts Occasionally mechanical parts wear out or break and you will want to have some spare parts on hand to prevent any loss of work while waiting for an ordered part to arrive We recommend that you have the following spare parts on hand e R

Often when we hold or fold a quilt top it appears to be relatively flat However when that quilt top is laid on top of the batting we can immediately see that the edges are wavy or there is fullness in the interior Some fullness can be quilted out but trying to quilt an area with a large amount of fullness often results in puckers and pleats in the quilt top Some parts of the quilt top may need to be ripped out and re pieced or you and or your client should be willing to accept some amount of puckers and or pleats If possible try to lay the quilt 4 1 top flat on a large floor area while customer is present Measure the width and length in several places to compare each measurement to the next Are the seams pressed correctly Most quilt makers press their seams as they piece the top however sometimes there are problems in how the pressing was done If the seams are pressed open it will be difficult if not impossible to stitch in the ditch because there is no ditch If the seams are pressed to one side often the ditch starts on one side but the pressing changed direction and the ditch ends up on the other side If you are stitching in the ditch you will need to follow the ditch to which ever side it goes Wavy Borders Some quilts have an hourglass shape where the top part is a certain width then the middle section of the quilt is not as wide and the bottom part becomes wide again This is usually due to the way the
