Assist Arm Motion Adjustment (DT-50A Only)
This section applies to the DT-50A only. The DT-50A Assist Tower is moved by the operator as
required anywhere around the top of the Tire. The Assist Tower is supported by the Assist Arm which
is connected to the Tower through two adjustable Pivot Points. One Pivot Point is located on the
Assist Arm and the other is located where the Assist Arm connects to the Tower. The ease with which
the Assist Arm moves is controlled by these Pivot Points through a threaded shaft and two locknuts on
each Shaft.
Refer to the figure on this page and the procedures below.
To Decrease the Assist Arm’s resistance to motion:
Select the Assist Arm Pivot Point or the Assist Arm Tower Pivot Point.
Loosen the Top Lock Nut by one or two turns.
