- Removal
of the Needles
SFM1 needles are relatively easy to remove. The key is to be gentle and slow the
same as with installation. Begin by grasping the hubs of all three needles and
turning them in a block about a
n eighth
turn anticlockwise, then a
⅛
turn
clockwise. You should hear and feel a cracking sound as the stainless steel
needles break the gummy bond with the sapwood. Remove each needle
individually. Place your left hand index knuckle against the stem to brace as a
pivot point and your right hand as a guide on the cable. The right hand will not
and should not apply any pulling force as this could damage the needles.
If the needles are especially tight you may need to use an additional lever such as
a
fl
at
bade
screw
driver.
If
this
is
required
it
must
be
used
very
carefully
and
only
in short distances. Attempting to lever the needle out in a single pass with a
screw driver
WILL
bend and most probably break the needle.
