INSTALLING RECEIVER MOUNT MODEL: 350/350S/750R
The Blaster 350/350S is a dedicated, Class 3, receiver (hitch) mount salt spreader. Prior to installation, be certain that the
vehicle receiver is in good working order, is rated for at least a 500 lb. tongue load, and is fastened to the vehicle securely.
CAUTION - The spreader is a large heavy item that should be installed with an assistant. 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 cover aside until
installation is complete. Retain original packaging for storage purposes.
2.) Locate the large hitch pin and cotter clip from the hardware package. Set these items aside, as they will be used later
during the installation.
3.) Inspect the vehicles receiver tube and check for rust, dirt, or foreign debris that may have collected in it. If there are any
blockages clean with compressed air and a wire brush.
4.) Apply good quality grease to the inside of the receiver tube, this will prevent rusting and make the spreader easier to
remove at the end of the season.
5.) The framework will have four 1/2-13 x 3” SS Bolts already installed in the mounting holes for the stinger. Remove the
1/2-13 SS Locknuts and 1/2” SS Flatwashers and apply a light oil to the threads, this will make assembly easier; yet will
not affect the locking properties of the safety nuts. Place the stinger over the bolts, replace the nuts and washers and
fully tighten. (Note: The mounting tube may be placed in either the raised or lowered position by flipping the stinger
over. This is owner preference) The DPS version is always installed with a downward angle for the two round stingers.
6.) Lift the spreader unit upright (hopper opening facing up) with mounting tube pointed toward the truck.
7.) Slowly slide spreader mounting tube into the vehicles receiver until the through holes in receiver match through holes
in spreader. (See note below)
8.) Insert the large hitch pin through the receiver tube and spreader mounting tube. Secure with the cotter clip.
WARNING – The cotter clip must be in place for safe operation.
9.) Place the cover over the hopper and secure clamps on left and right sides.
NOTE: •The spreader mounting tube has 2 pre-punched hole sets to provide some adjustment when installing the unit.
•Always use the hole set that places the unit closest to the vehicle but without touching it.
WARNING – Never attempt to drill new holes in the spreader mounting tube, contact your local trailer hitch supplier
about relocating or replacing you current hitch, if mounting problems occur.
10.) Use the Ratchet Tie Down Strap and Tie Down Hooks to tie spreader to vehicle frame to elininate any rocking of the
spreader.
