Safety
Before attempting any procedure in this book, these safety instructions must be read and understood by all workers who
have any part in the preparation or use of this equipment.
For your safety warning and information decals have been placed on this product to remind the operator of safety
precautions . If anything happens to mark or destroy the decals, please request new ones from Trynex, International.
Unit must be strapped down and locked into position before operating vehicle.
Never exceed the Gross Vehicle Weight Rating of vehicle. Failure to do so may limit a vehicles
handling characteristics.
Never attempt to take a unit o a truck with material in it.
Never exceed 45 m.p.h. when loaded spreader is attached to vehicle. Braking distances may
be increased and handling characteristics may be impaired at speeds above 45 m.p.h.
Never allow children to operate or climb on equipment.
Always check areas to be spread to be sure no hazardous conditions or substances are in the area.
Always inspect unit for defects: broken, worn or bent parts, weakened areas on spreader or mount.
Always shut o vehicle and power source before attempting to attach or detach or service
spreader unit. Be sure vehicle/power source is properly braked or chocked.
Always keep hands, feet, and clothing away from power-driven parts. Remember it is the
owner’s responsibility to communicate information on safe usage and proper maintenance of
all equipment.
Always make sure personnel are clear of areas of danger when using equipment. Maintain 60'
distance from all bystanders when operating the spreader.
Inspect the unit periodically for defects. Parts that are broken, missing, or worn out must be
replaced immediately. The unit, or any part of it cannot be altered without prior written
permission from the manufacturer.
Never use V-Maxx 8550 with foreign debris in the spreader. These units are designed to handle
clean, free-owing material.

Safety
(continued)
Always inspect pins and latches whenever attaching or detaching spreader, and before
traveling.
Never leave material in hopper for long periods of time. Be aware that all ice melters are
hygroscopic and will attract atmospheric moisture and harden up.
Remember, most accidents are preventable and caused by human error. Exercising of care
and precautions must be observed to prevent the possibility of injury to operator or
others!
Never operate equipment when under the inuence of alcohol, drugs, or medication that
might alter your judgment and/or reaction time.
Before working with the spreader, secure all loose tting clothing and unrestrained hair.
Always wear safety glasses with side shields when servicing spreader. Failure to do this
could result in serious injury to the eyes.

Vehicle Harness Wiring Instructions
Step 1: Take harness assembly and route from the rear of the vehicle to the front. Route harness along frame and attach to
frame hole and frame supports. It is not recommended to attach to fuel or brake lines for obvious reasons. Do not route close
to exhaust system or engine, even though Snowex uses high temperature wiring. It still could melt under extreme heat and short the
spreader electrical system, as well as the vehicle electrical system.
Step 2:
Mount rear plug on bumper using supplied bolts, locate towards the center of the bumper to reduce the amount of
debris the tires will throw to the rear. Important: Apply a small amount of dielectric grease to the plug. Also try to mount so
plug faces upward to help keep plugs tightly sealed.
Step 3: Secure harness from the rear to the front using heavy duty ty-wraps or frame clips along the frame and lighter duty
ty-wraps everywhere else.
Step 4:
Layout harness portion that connects to the battery along the re wall and fender well. Do not connect power leads to
battery yet. Drill a 3/4" hole in the re wall, or use existing access hole, for the control portion of the harness and route
connector and harness through hole. Be sure to check the area on the other side of the re wall to make sure you are not
drilling into the vehicle harness or a control module. Generally you can drill on either side of the steering wheel for a good
location.
Step 4A:
The power harness from control box to battery will need to be routed from the inside of the cab to the battery – this
results from the large high amperage connector. Route leads with lugs to battery — do not connect power at this time.
Step 5: Connect harness to the back of the controller and mount to a suitable location. NOTE: You may want to contact
customer before mounting controller as some prefer not to have holes drilled into the dashboard. Ty-wrap loose controller
harness and move to the engine compartment. Do not mount close to any heater vents.
Step 6:
Connect power leads to the battery: Red + Positive, Black – Negative, always connect to the primary battery if using a dual
battery system. Secure loose loom to any other large or medium vehicle harness with medium duty ty-wraps this will secure
wiring harness.
Step 7:
Push the ON/OFF button on the controller to check for power; when that has been conrmed turn power OFF. The electrical
portion of the installation is complete.
