ADJUSTMENT OF
PRESSERFOOT LOCK
ASSEMBLY
NOTE:
The Presserfoot Lock Assembly needs to
be adjusted ONLY if the Presserfoot Rod is
not holding.
The Presserfoot Lock and Backplate
Assembly sketch and photograph at left
shows the Presserfoot Lock principle and the
proper placement of the Locking Cam (#2 at
left). When the Backplate is in place, the
Locking Cam should sit on a slight angle to
the Presserfoot Rod (#1 at left) as shown.
Shims are placed between the Backplate and
Housing to adjust for wear (#3 at left). Add or
remove shims as needed to get proper angle
on locking cam (#2) as illustrated. If the rod
slips, shims should be removed.
To assemble, first assemble the Presser
foot Lock Release, Spring and Pin (#4, #5 and
#6 in photo at left). Then insert the Presserfoot
Rod (#1 at left).
Insert a screw driver (#7) over the
Presserfoot Rod (#1) and under the
Presserfoot Lock Release (#4) to hold the
Presserfoot Lock in the release position when
replacing the Backplate. This must be done to
prevent damage to the Backplate and to
properly tighten Backplate screws. It will not
go together without the lock being released.
Be sure that shims (#3) are in place before
final reassembly of the Backplate. Replace
Locking Cam (#2).
BEFORE REPLACING THE BACKPLATE,
be sure the sharpener has been moved down
(1/2" - 13mm) to prevent damage to sharpener
tripping mechanism.
