INSTALLING HINGED MOUNT MODEL: (35500)
This section covers the installation of a BLASTER 750 & 750S on a vehicle as hinged mount.
CAUTION –
This salt spreader is a heavy,
bulky item that should be installed with assistance.
As with any new equipment installation read and understand all instructions prior to starting the job, and do not hurry through it. A correct
installation now can save time and money later.
1.) Using an assistant, remove the spreader unit and all loose components from the packaging and set the cover aside until installation
is complete. Retain original packaging for storage purposes during the “off” season.
2.) Find the Driver and Passenger Side Bed Rail Brackets (3 & 4) and center along the top of each bed rail with the slot over the trucks
stake pocket. Attach using 1/2-13 x 3” Bolt (11), 1/2” Flatwasher (14) and 1/2-13 Toggle Wing (2) through the slot and stake pocket.
Hand tighten both sides.
3.) Slide the Driver and Passenger Side Bed Rail Brackets (3 & 4) out toward the back of the truck. This will assist in determining the
correct distance for mounting the spreader away from the tailgate, approximately 2" of clearance.
4.) Place the Driver and Passenger Side Bumper Plates (1 & 2) on the bumper. Slide the Hinge Pin (5) through the bed rail bracket and
into the socket on the bumper plates. Lower the tailgate to check that it will still function properly.
5.) Before drilling any holes double check that the Driver and Passenger Side Bumper Plates (1 & 2) are parallel and level with each other.
Use a square or level to check that the Hinge Pin (5) is vertical and square to the Driver and Passenger Side Bumper Plates (1 & 2) and
Driver and Passenger Side Bed Rail Brackets (3 & 4). NOTE: The driver and passenger side mounting components are mirror images
of each other, and each side must be installed in exactly the same manor for the spreader to open and close properly. After everything
has been checked, remove the Hinge Pins (5) and keep them handy, they will be used shortly. Tighten the toggle bolts in the Driver
and Passenger Side Bed Rail Brackets (3 & 4).
Do not exceed 30 Ft. lbs. of torque.
6.) If possible clamp the Driver and Passenger Side Bumper Plates (1 & 2) to the bumper and use them as guide for drilling, if that is not
possible use a center punch or scribe to mark the holes. Mount the plate using 3/8-16 x 1” Screws (8), 3/8” F;atwashers (13), and
3/8-16 Locknuts (12) that are included in the swing mount hardware package.
7.) Install the two Hinge Channel (6) on the driver side (left) of the frame. Install the two Locking Arm Assemblies (7) on the passenger
side (right). Install the Hinge Pin (5) on the passenger side and lock it in place in the bumper plate base with the 1/4” Snap Pin (16)
provided. Pull back the two latches on the passenger Locking Arm Assemblies (7) to their open/locked position. With an assistant, lift
the spreader upright (hopper opening face up) and set it on the newly installed bumper plates. With the assistant holding the
spreader, slide the “C” channels outward from the main frame so that the Hinge Channel (6) on the driver’s side line up to allow
installation of the driver side Hinge Pin (5). Drop the Hinge Pin (5) through to the Driver Side Bumper Plate (1) and lock it in place with
the other 1/4” Snap Pin (16). When the “U” shaped ends are placed around the passenger side Hinge Pin (5), release the spring-
loaded latches to the closed position and push downward to lock. The spreader should now be supporting itself.
8.) Thread 3/8-16 x 3” Bolts (10) into the bottom of the driver side bed rail bracket but do not tighten. Place Bolt Tip Cover (17) on the end
of each bolt. Tighten bolts firmly. NOTE: If Bolt Tip Covers (17) are not used, damage to vehicle paint may occur. Repeat this step on
the passenger side.
9.)
Measure to ensure that the spreader is centered on the vehicle and is supported by the mounting before proceeding.
There will
be 6 pre-punched holes on the latching side of the spreader frame, 3 on the on the upper “C” channel and 3 on the lower. Use these
holes as a guide and drill 3/8" Dia. through the adjustable “C” channels. Install 3/8-16 x 1” Bolt (19) with 3/8” Flatwashers (12) and
3/8-16 Locknuts (11) in each hole.
10.) Open the passenger side latches and swing the spreader unit away from the truck to check for binding. If binding occurs it will be
caused by one or both of 2 situations:
11.) The bolts holding down the Bumper Plates (1 & 2) are striking the frame support blocks. Remove spreader from mounting and
reposition 1 bolt at a time until all are clear. New holes can be drilled if necessary.
12.) The Hinge Pins (5) are not properly lined up. Adjust Hinge Pins (5) one side at a time by loosening the bolts holding the Bed Rail
Bracket (3 & 4) down and reposition the brackets slightly; this will in turn adjust the Hinge Pin (5).
Swinging to passenger side requires removal of driver side Hinge Pin (5).
Make sure all bolts are tight.
13.) Secure the cord coming from the motor to the spreader frame and lower adjustable “C” channel with wire ties. Rout the cord out to
the pivot. This will take up the slack in the cord and still allow the spreader to swing. This can be changed at any time by simply
routing the cord to the other side.
14.) The cover may now be installed and latched both sides. The spreader unit can be pivoted from either the driver or passenger side.
15.)
WARNING – TO AVOID DAMAGING YOUR VEHICLE, NEVER ATTEMP TO SWING THE SPREADER WHEN LOADED WITH
MATERIAL.
NOTE: For your convenience the mounting components will not need to be taken off the vehicle to remove the salt spreader. With an
assistant holding the unit remove the driver side hinge pin, open both passenger side latches and lift the spreader up and away.
Replace the driver side hinge and security pins.
