9.2.2
Using the Standard U-Shaped Mounting Bracket
If the standard U-shaped Mounting Bracket will be used to mount the control head, the following
mounting procedure is recommended. This bracket is included with the Mounting Bracket Kit listed in
Table 4-3 (page 18).
1.
Using the Mounting Bracket as a template, mark and drill mounting holes into the mounting
surface as required. The round and elliptical holes in the bracket’s vehicle mounting surface are
symmetrical so forward/backwards positioning is not important during this step. However,
positioning is important in the next step.
CAUTION
When drilling holes, be careful to avoid damaging some vital part of the vehicle (fuel
tank, transmission housing, etc.). Always check to see how far the mounting screws
will extend below the mounting surface prior to installation. After drilling pilot holes,
remove all metal shavings from them (i.e., deburr the holes) before placing the bracket
and installing the mounting screws.
2.
Postion the bracket at the mounting surface so the two round holes in its two side “ears” are
nearest to the normal location of the operator (typically towards the rear of the vehicle) and the
two slotted holes are farthest from the normal location of the operator (typically towards the front
of the vehicle).
3.
Install and tighten the mounting screws. Screws for mounting the bracket to the mounting
vehicle’s surface are not included, as all installations differ. Self-threading screws are
recommended. Sheet metal screws should not be used.
4.
Verify the bracket is held firmly to the mounting surface. Firm mounting prevents unreasonable
vibration, which could damage the control head and/or cause its cable connections to loosen.
5.
Slide the control head into the bracket, placing the two pegs protruding from its left and right
sides into the respective round holes in the bracket’s two side “ears.”
6.
In each side “ear” of the mounting bracket, start a #8-32 socket-head cap (Allen) head screw with
a lockwasher and a flat washer by inserting the screw through the slotted hole in the bracket and
then into the threaded hole in the side of the control head. This hardware is included with
Mounting Bracket Kit. The lockwasher should be adjacent to the screw head and the flat washer
should be adjacent to the bracket. Turn each screw clockwise as observed from the head of the
screw.
7.
The control head can be positioned at various angles for best display viewing at the normal
position of the operator. As necessary, turn it on the pegs to a good position and tighten both
screws using an 1/8-inch hex key (Allen) wrench until the control head is held firmly in place. Do
not over-tighten.
9.2.3
Using the Mounting Pedestal (Optional)
An optional Mounting Pedestal, part number MACDOS0012, may be purchased separately to replace the
standard U-shaped Mounting Bracket. This pedestal can be attached to the bottom of the control head as
shown in Figure 9-5 and then mounted to a mounting surface below the two. It can also be attached to the
top of the head and then mounted to a mounting surface above the two.
