Feed dogs dropped on brother pq1500s, won't come back up
My feed dogs have dropped, this is a four position feed dog, but they will not rise above the surface again. I have looked under the machine for a way to adjust them, but am unable to find a way. I do not have the schematics of this machine either. Any suggestions will be appreciated.

Is the feed dog raised into sewing position and not dropped as for darning? Feed dogs need to be in the raised position in order to pull the fabric through the machine.
If the stitch length is set too short, it will cause the fabric to barely move thereby causing the machine to stitch in one place.
Raise your presser foot and gently rotate the handwheel and watch the feed dogs. Do they rise when coming to the front of the machine, move toward the back of the machine, drop down below the needle plate, and move forward to the front of the machine again? If so, the feed dogs are working properly.
If the feed dogs never rise, they are in the dropped position for darning or free motion quilting when you would move the fabric manually.
If, on the other hand, the feed dogs do not move at all, then they are seized and you should probably get your machine serviced.
Check that the stitch length is set to make ~10 stitches per inch. This stitch is long enough to actually move the fabric. If the stitch length is set too short, the fabric will stay barely move and the needle will stitch almost in place.
Check that the feed dogs have not been dropped for darning or free motion quilting. In this position, they do not rise and are, therefore, unable to contact the fabric to pull it through the machine.
With the presser foot raised and using no fabric, hand rotate the handwheel and watch if the feed dogs actually drop down below the needle plate, move toward the front of the machine, then rise above the needle plate, and move toward the back of the machine. If the feed dogs are moving in this manner, then they are functioning properly.
Is there lint or gunk stuck in the feed dogs? This will restrict the ability of the feed dogs to grip the fabric.
Are the feed dogs worn? Are the little teeth worn so there are no sharp points?
What type fabric are you using? If it is very light-weight or slick fabric, the feed dogs will have a difficult time gripping the fabric. Most machines have a presser foot pressure adjustment so that more pressure is applied between the presser foot and the feed dogs. Consult your Owner's Manual. The adjustment is usually a dial either on the left side of the machine, on the front of the machine located above the needle bar, or on vintage machines it is usually a skrew located under the top lid above the needle bar.
Either something is broken or the feed dogs have been lowered. This is done when using things such as automatic buttonholers and such. There is a level, usually under the plate, that lowers the feed dogs.
Tension generally does not affect the feed unless it is way too tight. Most reasons for fabric not advancing under the presser foot is that the feed dogs have been dropped for darning. If the feed dogs are operating properly, as the handwheel turns the feed dogs should rise above the plate, move toward the back of the machine pulling the fabric, drop down, come forward and rise again.
The other possibility is that the presser foot pressure has been released so the presser foot is not holding the fabric down on the feed dogs. Some machines have a spring-loaded knob on the top of the machine, a dial, or something to adjust the amount of pressure the foot applies. Consult your owner's manual.
Look at the feed dogs to see if they are rising above the needle plate at least 1 mm. If not rising lint may have felted between the feed dogs and the needle plate. It could also be the feed dogs have been lowered, or the height has slipped. If the feed dogs are above the needle plate turn the hand wheel and see if they are moving from the front of the machine to the back. If not it is a length adjustment. If this is normal the pressure on the fabric may be too low. Another problem may be the timing of the feed dogs. The feed dogs should rise above the needle plate when the needle leaves the fabric and descend when the needle comes down into the fabric. This requires an expert to fix.
when the feed dogs are in the up position the sewing machine will sew but when the feed dogs are down postion it will darn try the feed dog lever again if you can move the feed dog lever and the feed dogs respond going up and down then you know that the feed dogs are working and are not broke but if they do not respond then they need to be checked to see what's wrong with them
Ignore all the other comments, they are wrong. The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).
