The handle adjust bar (86215130 - PRV
NO.14344) for the polishers are
individually preset at the factory for
optimum locking efficiency and minimum
effort of engaging. It should not be
necessary to adjust the handle adjust bar
unless the relationship of the handle adjust
bar nut (86136360 - PRV NO. 57275) or
fixed clamp bolt (86136700 – PRV NO.
70692) and their corresponding nuts
(86136360 – PRV NO. 57275) and washer
(86010720 – PRV NO. 87086) have been
disturbed. The handle can be positioned to
be locked with the handle adjust bar
pointing either up or down. In order to
change the position the handle and bolt
must be removed and rotated 180
degrees. It is incorrect to make it lock
opposite from the way it was assembled
by applying more force to the nut. From
the factory the locking is in the up position
when the machine handle is locked. The
pivot pin (86222560 – PRV NO. 66334) on
the handle adjust bar is off center, in
relationship of the screw to the axis of the
(see drawing). To adjust handle adjust bar,
tighten nut on handle while in the locked
position. The handle is locked when the
screw is to the outside of the machine and
the flat on the opposite side of the handle
is flush to the bracket.

1. To adjust handle lock, tighten nut on handle
while in the locked position. Optimum locking
force and ease of locking is accomplished
when the locking lever nut is set to a torque of
30 to 50 inch pounds in the locked position.
2. Gap between clamp halves at the front should
be to the gap in rear when the handle adjust
bar is adjusted properly and in the locked
position (gap approximately 1/16").
