OPERATION

The Fume Arms have two adjustment points that can be
changed at any time to give the arm greater flexibility.
Friction disks, located at the base of the arm and at the
first hinge point, can be tightened or loosened with a
7/8” wrench. (Figure 9) Simply tighten the nut on the
friction disk to make the joint stiffer or loosen to give the
joint freer, less restricted action. Be careful not to over
tighten the disk as this could cause permanent injury to
the arm.
Some fume arms come equipped with a shock or strut.
The shock is not adjustable. (Figure 10)
