Removing Covers
MAKE SURE THE MACHINE IS NOT PLUGGED IN BEFORE
STARTING.
On the back of the machine, remove the screws as shown. On
the back of the open arm you will find covers on two of the
screws. The third screw on the arm is a 2.5mm Allen screw.
Carefully lay the machine on its back and remove the three
screws as shown.
Remove the hand wheel cover and the dial. They come off by
gently prying with a small screw driver. Remove the hand wheel
screw and cover screw then remove the hand wheel. Remove
the screw under the hand wheel. You can now carefully take off
the rear and side covers which come off together.

Clean and Lubricate
The best way to remove lint from the machine is with
compressed air. Blow all the lint from the machine. Remove all
lint from the gears and again from the bobbin area and feed
dogs.
When oiling your machine make sure you use a good quality
oiler and clear sewing machine oil.
This type of oiler is good because it has an extendable
spout and only lets out small drops of oil. A drop of oil is the
amount of oil left on the tip of a needle if you did it in oil.
Clean all lint from the open arm area and needle bar area. You
can access the needle bar area from the back though the access
holes. Oil all moving parts but be careful to use very little oil in
the needle bar area as the oil will find its way onto your fabric.
Clean off any excess with a soft cloth.
4
Clean and Lubricate Continued
Remove the needle plate and hook. Clean the race and race
cover of all lint and old oil. Use a bit of oil to clean the race
grooves. Re oil the race and hook pin.
MAKE SURE YOU ONLY TOUCH THE OUTTER EDGES OF THE
BOARD WITH YOUR HANDS.
Remove the screws from the power
board. Unplug the color coded wires from the board. The board
will fold down towards you.
5
Clean and Lubricate Continued
Clean and oil all moving parts
behind the board. Again do not use too much oil. Be careful not
to get oil on the plastic parts. Clean off any excess with a soft
cloth.
The gear set behind the power board requires
light gear grease.
Hook Position and Timing
Turn the hand wheel so the needle is at its
lowest position. The tip of the hook should line up with the edge
of the race.
6
Hook Position and Timing Continued
If they do not line up, loosen the Allen screw on
the hook drive arm ½ turn. Line up the hook. Tighten the screw
and recheck the position.
Locate the hook crank behind the power
board on the back of the machine. Set the machine to right
needle position by pushing the needle bar to the right almost all
the way. Turn the hand wheel until the hook and needle meet.
The hook crank should line up as shown.
The hook and needle should meet as shown.
7
Hook Timing Continued
If the crank does not line up, locate the Allen
screw on the back of the hand wheel. Loosen the screw ½ turn.
Line up the hook and needle as shown. Tighten the screw and
recheck the timing. MAKE SURE YOU DO NOT LET THE HAND
WHEEL MOVE IN OR OUT.
Bobbin Tension
To check the bobbin tension, insert a bobbin wound
with medium weight, light color thread into the bobbin case.
Snap the bobbin case onto the hook. Hold the bobbin case and
hook up with the thread. If you jerk your hand the hook and
bobbin case should drop down 1 – 2 inches.
Turn the screw clock wise to tighten and
counterclockwise to loosen.
