1.49. DO NOT SIDE LOAD BULK ABRASIVE BLASTER TRAILER.
Do Not exert side loads on the trailer wheels. An example of side loading would be pushing the
trailer mounted bulk abrasive blaster on its side with a fork lift or other similar heavy
equipment. Move the bulk abrasive blaster only by pushing or pulling at the hitch or brake
actuator.
1.50. CLOSE BRAKE LINE BALL VALVE BEFORE BACKING UP.
(On units with hydraulic brakes only) Do Not attempt to back up before closing ball valve (#15)
on brake line since the backward pressure will activate brakes. See Section 9.3(a).
1.51. DO NOT EXCEED TRAILER AXLE RATING.
Do Not load the bulk abrasive blaster with abrasives that will load the axles above the
manufacturer’s load rating. The trailer load capacity is designed for use of abrasives with a bulk
density of 100 pounds per cubic foot. For abrasives of higher density reduce the volume of
abrasive loaded into pressure vessel. See Section 2.2.
1.52. DO NOT HAUL YARD TRAILERS ON PUBLIC ROADS.
Do Not tow yard trailer mounted bulk abrasive blasters on public roads. Only highway trailers
which are equipped with hydraulic or electric brakes, wheels fenders, and lights are permitted
on public highways. Consult local state DOT requirements.
1.53. DO NOT HAUL TRAILER MOUNTED BULK ABRASIVE BLASTER LOADED.
Do Not tow trailer mounted bulk abrasive blasters on public roads with abrasive loaded inside
of vessel. Highway trailers are rated for transporting abrasive at low speeds only (15 mph).
1.54. DO NOT EXCEED 65 MPH TRAILER SPEED.
Do Not tow highway trailer mounted bulk abrasive blasters at speeds exceeding the 65 mph tire
rating. Replacement tires must be of equivalent speed and load ratings. See Section 9.3.
1.55. DO NOT TRANSPORT BLAST EQUIPMENT LOADED WITH ABRASIVE.
Portable abrasive blasters are not intended to be moved or transported loaded with abrasive. Do
Not attempt to roll portable abrasive blasters with abrasive loaded in or on the pressure vessel
