Use compressed air to blow out any excess WD 40, and carefully wipe out any additional excess product
using a separate rag.
Be sure to keep your hands away from the handles to prevent accidentally starting the
motor, or use the master switch on the machine to turn off power when working in the hook area.
Note: WD
40 is not a lubricating agent. Oil must be applied to the hook after cleaning with WD 40.
Check to see that the rag is still in place under the hook area and is out of the way of any moving parts. Now
apply one to two drops of oil to the hook assembly as shown in Photo B, between the dark-colored bobbin
basket and the silver hook mechanism.
Either turn the flywheel by hand a few revolutions, or push the toggle switch towards the white dot on
any handle to move the needle up and down a few times to help distribute the oil around the hook
assembly.
Keep the rag out of the way of moving parts, and start the machine again by pushing the toggle switch away
from the white dot on any handle to start the machine in manual mode. Allow the machine to run for 10-15
seconds so that the oil can be distributed in the hook assembly.
Turn off the machine by pushing the toggle switch away from the white dot on any handle again, and wipe
off any excess oil in the area using a separate rag. Remove the rag from below the bobbin area. Re- thread
the machine, insert a bobbin and bobbin case, and sew on a scrap piece of material to remove any excess
oil and make any minor upper tension adjustments.
If you notice the machine getting noisy during normal operation, the hook assembly may be dry and
needs oil.
