MOUNTING THE LTA 2.0
TELESCOPIC ARM
(continued)
Disconnect the mounting bracket from the arm before
mounting, by removing the 1.75” bolt (Fig. 3C), and
sliding the post out of the friction block. Mount the
telescopic arm mounting bracket to the wall. Standard
mounting height is 5 ft. (130 mm) from the work table
to the center of the bracket. Refer to Figure 2 for
drilling dimensions.
Remount the arm to the mounting bracket by sliding
the friction block over the post of the bracket (Fig. 3A)
and replacing the 1.75” bolt and nut (Fig. 3C).
ADJUSTING THE FRICTION OF THE
TELESCOPIC ARM
The amount of friction resistance should be set such
that the arm is comfortable to move (always test both
up and down movements), yet hold its position against
gravity once positioned.
To adjust the friction resistance of the hood move-
ment, fold back the rubber band onto the hood, and
push up the flexible hose, exposing the connection
blocks. Use an 8mm wrench to adjust the bolt/nut
pairs as shown in Fig. 4.
