Timing
needle bar height 15 class
Timing
200 series
Checking the timing on your machine is easy because there are timing
marks that show you where the machine must be set.
Remove the needle plate and bobbin case.Turn the hand wheel towards you
until the needle bar is in the lowest position. You will see two marks
on the needle bar with the top one being flush with the bottom of the
bushing. If it is not loosen the needle bar screw and move it up or down
to set the marks. Make sure you keep the needle bar straight (needle
clamp screw should be straight to the right)
Next
turn the hand wheel until the lower timing mark is flush with the
bushing. At this point the hook tip should be just above the eye of the
needle as shown.
If
the hook tip and needle do not line up as shown, turn the machine on its
back making sure the needle bar does not move. Loosen the two timing
screws on the hook pulley (only loosen them ¼ turn). Move the hook to
line it up with the needle. Tighten the screws and recheck the timing.
The feed dogs should be in the down position when timing the machine. If
the feed dogs are up when the timing is set as shown, the hook timing is
out 180°.

300 series
Remove the needle plate and bobbin case. Turn the hand wheel towards you
until the needle bar is in the lowest position. You will see two marks
on the needle bar with the top one being flush with the bottom of the
bushing. If it is not loosen the needle bar screw and move it up or down
to set the marks. Make sure you keep the needle bar straight (needle

Timing
600 series
To
check the hook timing first you need to check the needle bar height.
Bring the needle bar to its lowest position. You will see two timing
marks on the needle bar.
If the
upper timing mark is just visible under the bushing as shown the needle
bar is at the right height. If not loosen the needle bar clamping screw
and carefully move the needle bar up or down. Do not twist the needle
bar sideways.
Timing
700 series
Timing
500 800 series
Timing
6000 series (drop-in)
Locate the timing marks on the needle bar. Insert a new needle into the
needle clamp. Set the needle position to the center. Bring the needle to
the lowest position.
With
the needle bar in the lowest position one timing make should be visible.
Slowly raise the needle bar until the mark is level with the bushing. At
this point the hook tip and needle should meet.
If
the hook and needle do not meet as shown and the needle bar height is
right as per the timing marks the timing will need to be adjusted.
Turn
the machine onto its back. Locate the hook drive shaft belt pulley.
Loosen the two screws ½ turn each. Carefully turn the hook with your
hand until the hook and needle meet.
Do
not turn the hook too far and make sure the feed dogs are down when the
needle is down. If the feed dogs are up when the needle is down the
timing is 180° out. Retime the machine so the feed dogs are down when
the needle is down.
Timing
6000 series (wind in place)
Insert a new needle into the needle clamp. Set the needle position to
the left. Bring the needle to the lowest position. Slowly bring the
needle bar up until the hook and needle meet. The hook tip should be
just below the middle of the scarf of the needle.
The
needle should have come up 2.4mm to 2.7mm from its lowest position.
If
the hook and needle do not meet as shown you will have to adjust the
hook timing.
Turn
the machine onto its back. Locate the hook drive shaft belt pulley.
Loosen the two screws ½ turn each. Carefully turn the hook with your
hand until the hook and needle meet. Tighten the screws and recheck the
timing.
When
the hook and needle are in position the timing marks on the feed lifting
cam should line up as shown.
If
the two feed timing marks do not line up when the hook timing is set you
will have to adjust the feed timing.
Locate the two screws on the feed drive gear. Loosen the screws ½ turn
each. Carefully turn the feed lifting cam to line up the two marks.
Tighten the screws and recheck the feed timing. Be careful not to turn
the feed lifting cam too far. To check this make sure the feed dogs are
below plate level when the needle is down. If they are up rotate the
feed lifting cam 180° so the
feed dogs are below the top of the needle plate.
Tensions
800 series
The
bobbin tension should stay constant but may have to be adjusted if the
spring was bent or thread was caught under the spring. Check under the
spring for thread or lint. Insert a full bobbin wound with medium
weight, light color thread. You should feel some tension but not enough
so you have to grip the thread hard to pull it. If the tension is too
loose or too tight turn the adjusting screw ¼ turn at a time to set the
tension.
The
result you are looking for is when the knot forms in the center on the
fabric.
Tensions
500 series
Loosen the screw on the top tension unit one turn. Remove the outer
cover. Check between the tension discs for thread or lint.
Turn
the adjusting nut ¼ turn at a time until the desired tension is
achieved. Replace the cap at 4.5 and tighten the screw. This resets your
top tension to a medium number.

2000 series
From
the open top of the machine, locate the top tension unit. The normal top
tension for your machine should be 3 - 4 on the tension dial. The bobbin
tension should not require adjusting. Stitch out a test seam. The knot
should meet in the center of the fabric.
If
adjustment is required, loosen the nut on the tension unit and turn the
adjusting screw ½ turn at a time and test stitch again. Continue until
the right tension is achieved. Make sure the dial is set at normal after
you turn the screw and before you test stitch.
Turning the adjusting screw clockwise will tighten the top tension
(increase). Retighten the nut and replace the covers on the machine.
