Needle Types
Needle Installation
Leatherwork needles are round on top, unlike home sewing machine needles� As a result, proper
installation must be exercised carefully� Improperly installed needles are the main reason users
call for help�
The needles have two distinct sides� One side has
a long channel or groove running the length of the
needle, and the other side has a short scarf (
A
)
(i�e�, a carved-out area) just above the needle eye�
When installed, the scarf (
A
) should face toward
the right as you face the front of the machine�
Ensure the needle is pushed all the way up into
the needle bar (

) before tightening screw (

)�

CAUTION:
If the needle is inserted the wrong
