Adusting the Angle

Tools Needed:
• 5/32" Allen Wrench

more than the lower screw in order to permit the
locking block to disengage from the caster barrel tab.
See Figure 110.
3. Using a drafting triangle or similar 90º angle tool as
shown in Figure 110, rotate the caster barrel until the
straight edge of the caster barrel tab is perpendicular
to the level surface.
