4 Checking and Securing Flats and Screws
Figure 4.1
Figure 4.2
The Quilt Maker Pro 18 VERSA has been designed using ats and special screws to help prevent loop li ming from
slipping, except at the hook. (If the hook cannot slip then something has to break when something goes wrong. The
hook is designed to be adjusted without removing the front cover.)
First check the torque specicaons chart on page 5,
then check the following locaons, making sure that
the rst screw of a med component has been xed
rmly on the respecve at on the sha:
1. The Pitman crank (Figure 4.1) (# 5 at screwdriver
2. The take-up lever driving link, (Figure 4.1) (3 mm
handle hex tool)
3. The main sha ming pulley (Figure 4.3) (2.5 mm
handle hex tool)
4. The hook-sha ming pulley (Figure 4.5 on page
13) (2.5 mm handle hex tool).
Note: The screws are generally posioned 120 degrees
apart. When the rst screw (Posion 1) has been
located and ghtened on a at, the second screw is then
ghtened, compounding the ghtness of the rst screw,
thus securing and assuring that ming will not change.
Note: The main-sha thrust collar has been replaced with
a brass counterweight which is no longer located on a at.
Note: It is important to check that the brass counterweight
ghtening procedure did not create a ght arm sha
condion. If so, readjust the counterweight again unl
there is no ghtness and minimal-to-no end-play. This is
checked by rotang the sha and checking a few mes
through a full 360° rotaon of the sha.
Counterweight Timing
Set counterweight ming as follows.
First Pitman screw up, edge vercal and aligned with
lier arm. At this posion, the counterweight chamfer
(the bevelled edge) always goes to the le side next to the
bearing and the slit is straight down with screws on boom
straight out at you (Figure 4.2).
The counterweight has a slit and can be adjusted. It is not
set on a at for ming.
