Disconnect the battery before removing or
replacing any electrical components.
WARNING
Overloading could result in an accident or
damage. Do not exceed GVWR or GAWR
ratings as found on the driver-side cornerpost
of the vehicle. See Loading Section to
determine maximum volumes of spreading
material.
CAUTION
Indicates a potentially hazardous situation
that, if not avoided, may result in minor or
moderate injury. It may also be used to alert

SWING AWAY®MOUNT INSTALLATION INSTRUCTIONS
SWING AWAY Mount Installation
1. Remove all mount assembly parts and hardware
from the shipping carton.
2. Install both top swivel supports to the top brackets
with one 1/2" x 1-3/4" cap screw, one 1/2" flat
washer and one 1/2" locknut per side. Tighten
snug but do not fully torque hardware at this time.
3. Set the driver side base plate on the bumper in the
approximate area that it will be installed.
4. Set the driver side top bracket assembly on the
truck bed rail and clamp in place.
5. Drop the hinge pin into place through the top
swivel support and into the base plate. Adjust the
base plate and top bracket assembly to provide at
least one inch of clearance between the hinge pins
and any point of the truck. The pin must also be
positioned vertically.

18. Center the connector channel between the end
channels.
NOTE: The pins must be vertical and the bracket
bosses must be aligned with each other. Any
misalignment will create difficulty in removal of
pins. Use shims as required to align parts.
6. Use the large slots in the top of the bracket as a
guide to locate and mark two holes. Check under
the bed rail for any obstructions before choosing
holes.
7. Remove the hinge pin and top bracket. Center
punch and drill two 17/32" diameter holes through
the bed rail in the marked positions.
8. Replace the top bracket and install bracket with
two 1/2" x 1-3/4" cap screws, two flat washers and
two locknuts. Tighten snug but do not torque at
this time.
9. Repeat this process on the passenger side of the
vehicle.
10. Replace the hinge pins through the top supports
and into the base plates.
11. Re-adjust the baseplates if necessary to ensure
vertical alignment with the top brackets and
clearance to the vehicle. Verify the hinge pins do
not bind when inserted in the top bracket and the
base plate.
12. Use the 5/16" pre-punched holes in the top
bracket as a template to center punch and drill two
11/32" diameter holes in the inside flanges of each
side of the truck bed. Check behind the bed rail for
any obstruction before choosing holes.
13. Install two 5/16" x 1-1/4" cap screws, two 5/16" flat
washers and two locknuts through the bracket and
inside flanges of each side of the truck bed.
14. Slide one end channel assembly into each end of
the connector channels.
15. Carefully remove the hinge pins from the truck.
16. Install the channel assemblies onto the hinge pins
with the labels right side up.
17. Slide the top channel assembly up the pins and
attach clamps to the hinge pins below the upper
end channel assembly to prevent the assembly
from sliding down the pins.

30. Place the spreader on the base plates.
NOTE: If the spreader obstructs the view of the
license plate check for any local regulations that
may apply.
31. Slide the top and bottom connector channel
assemblies up the hinge pins and align the holes
in the spreader angle frame with the holes in the
channel assemblies. Secure the spreader to the
channel assemblies with four 3/8" x 1" cap screws
and 3/8" locknuts per mount arm assembly.
32. Torque all eight cap screws to the proper value.
Refer to Torque Chart.
33. Verify all other fasteners are torqued to the proper
specifications.
34. Remove one hinge pin and swing the spreader
assembly. When returning the spreader to the
bumper, it may be necessary to lift the spreader
onto the base plate.
35. Choose which way the spreader will swing and fix
the hinge side by installing one 1/4" x 1-3/4" cap
screw and 1/4" locknut through the hole in the
base plate boss and hinge pin.
36. Install the hitch pin clip through the latch side base
plate boss and the removable hinge pin.
SWING AWAY® MOUNT INSTALLATION INSTRUCTIONS
26. Loosely install the base plates to the bumper with
three 3/8" x 1-3/4" cap screws, 3/8" flat washers
and 3/8" locknuts. Shim the top brackets and base
plates as required to prevent the hinge pin from
binding.
CAUTION
Do not operate the spreader or the vehicle
without securing the hinge pin into the base
plate.
NOTE: Place a piece of wood behind the drilling
area to protect the tailgate from the drill as it
breaks through.
20. Install one 3/8" x 1" cap screw and 3/8" locknut in
the end of each end channel to temporarily hold
the arm assemblies together.
21. Adjust the base plates to be aligned with the
bumper and verify that the hinge pins are vertical
and parallel with each other.
22. Use the pre-punched holes in the base plates
to locate and mark three holes on the top of the
bumper for each base plate. The holes should be
chosen in a triangular pattern with two holes in one
of the rows and one hole in another row. Check
under the bumper for any obstructions before
choosing holes.
23. Outline the position of the base plates on the
bumper with a pencil.
24. Remove the clamps, hinge pins and swivel mount
arm assemblies from the truck.
25. Center punch and drill three 13/32" diameter holes
in each side of the bumper as previously marked.
27. Reinstall the channel assemblies and hinge pins
on the truck. Verify that the caution labels located
on the end channels are right side up and located
on the top assembly.
28. Recheck all alignments of the channel assemblies
and hinge pins and torque the base plate
hardware to the proper value. Refer to the Torque
Chart.
29. Remove the 3/8" x 1" cap screws placed in the
connector channel assemblies.
19. Use the pre-punched holes in the connector
channel as a guide to drill two 13/32" diameter
