Hook-sha ming pulley
Tools needed: (2.5 mm handle hex tool)
Note: The hook-sha ming pulley rotates the
opposite direcon as the main sha ming pulley.
Carefully note the labeled rst screw (Figure 4.5).
Note: The hook-sha collar does not have a at.
The at is located on the hook-sha ming pulley
rst screw.
Important Hook-Sha Notes
The hook-sha turns two mes per stch and rotates
in the opposite direcon as the main sha. Please
carefully note which screw is the rst screw in the
direcon of moon and on the at.
The hook-sha pulley is set to a specic seng from
the end of the sha to allow proper needle-to-hook
distance adjustment. Adjust the collar to remove axial
play, not the hook-sha pulley, or the seng can be
thrown o, which may make it so needle-to-hook
distance cannot be adjusted.
The QMP 18 VERSA ulizes long collars with two
screws in line to help prevent the collar from pping
when ghtened, causing variaon of ghtness or
play, as the collar rotates 360º. To ensure that there
is no ghtness or play, the collar should be checked
through a full rotaon unl it has minimal ghtness
and minimal play.
4. Checking and Securing Flats and Screws - Connued
First Screw, First Posion Rule
The rst screw or rst posion is almost always*
located 120° apart in the direcon of rotaon from
the second screw or second posion. The rst screw
in direcon of rotaon goes on the at. (Figure 4.4)
* (The pitman screws are only 90 degrees apart
instead of 120 degrees.)

Note: First screw in direcon of moon goes on the
at. The rst screw is 120º before the 2nd screw. The
2nd screw is then 240 degrees before the 1st screw.
