Mounting the payload
1.
Extend the arm or dock it securely. Do not mount or
dismount the payload when you are using the built-in
dock, unless there is no alternative.
2.
Loosen the two-piece collar with a
32
3
-inch Allen
wrench
.
3.
If this is a top-mount (shown), position the collar for the
desired height and tighten it.
4.
If this is an underslung mount, remove the collar.
5.
Insert the gimbal post into the socket at the end of the
arm.
6.
If this is an underslung mount, have an assistant help
you position and tighten the collar.
7.
Dress hoses and cables with zip-ties to the gimbal post
and the elbow hinge block.
DO NOT MOUNT AND DISMOUNT THE PAYLOAD

Adjusting the rest position
The dynamic and preset mounting interface blocks have different adjustment mechanisms, but the process of adjustment
is the same.
Pitch
adjustment moves the bracket up and down, in a head-nodding motion.
Roll
adjustment rotates the
bracket, as viewed from the front.
1.
With the tool mounted and the arm undocked, let the arm extend toward the work area and, without letting go com-
pletely, let it move freely.
2.
If the arm consistently drifts to the same side, adjust the pitch down and the roll away from the direction of drift.
3.
If the arm drifts to either side, adjust the pitch down. Pitch should be as far up as possible without causing the arm to
be unstable.
Adjust a dynamic mounting interface
block
The block can be adjusted with the arm extended, as you
move around, to compensate for flex in the support or for
uneven floors.
•
Adjust pitch by turning the crank on the top of the
mounting interface block. Cranking clockwise pitches
the bracket down.
•
Adjust roll by turning the crank on the side of the block.
Cranking clockwise rolls the bracket counterclockwise.
Adjust a preset mounting interface
block
Adjustments are made with pairs of set screws.
1.
To adjust pitch, use the screws on the back of the block:
a.
If necessary, unload the bottom set screw by moving
the tool toward the back of the mounting interface
block.
b.
Back off one of the screws to create slack in the direc-
tion you want to move the bracket
c.
Tighten the other screw to move the bracket.
2.
Adjust roll with the side screws, and unload the set
screw by moving the tool to one side or the other.
3.
Tighten both screws in each pair snugly.
