Safety The Trout River Trailer is not “just a trailer”, it is also a powerful machine with various mechanisms that could be potentially dangerous, the following are some general safety rules pertaining to trout river trailers: • • • • • •
• • •
Never enter trailer with conveyor in operation When conveyor is running be sure to keep all body parts, clothing, etc. clear of inspection doors, conveyor belt, or any other moving parts; failure to do so could result in serious injury Be aware of the tailgate position, and stand clear when opening or closing When trailer is unloading be sure to stand clear of the rear of the trailer, as to not get injured from load exiting the tub Ladder is designed for a maximum of 250 pounds; do not exceed this limit. Top ladder rung is not meant to be a step, it is only there as a “hand-hold”; do not use as a step Trailer hydraulic system is designed to run in access of 2500 psi, this amount of pressure could be very dangerous; always take care when connecting hydraulic lines, that it is done properly, and replace any damaged hydraulic components immediately. Always be sure system pressure is relieved before maintenance o Always connect return line first and disconnect last Air system can also be dangerous, be aware of air lines, that they are not damaged, and relieve system pressure before maintenance When working on the trailer, be sure all power systems are disconnected, unless otherwise instructed or needed, always be aware of present dangers As Rear Lift trailer lifts, and lowers, be aware of all pinch points, as these could cause serious damage

Hydraulic System Requirements In order to run the rear lift properly, you will need: •
•
70 gallon hydraulic tank or larger o This ensures there is enough oil to run all hydraulic components ▪ The lift cylinders, and door cylinders both remove oil from the tank as they open o It is important that, even after reduced oil volume, that there is enough to keep the system running cool as the hydraulic motor runs Hydraulic pump capable of producing 28-40 GPM@2800psi

Hard, Even, Level Ground Just like a dump trailer, it is crucial that the trailer only be raised when on hard, even, level ground. • • •
Uneven ground can increase the risk of a tip Soft ground can cause damage as the bogey needs to roll forward as the trailer lifts Ground that is not level can cause strain on the lifting components, and can increase the risk of a tip
Apply brakes on truck or trailer - Not both! • •
As the tub goes up, the bogey moves forward, if both brakes are locked this can seriously damage the lifting mechanism Be sure brakes are released on one or the other
➢ It is important that the top bogey flange stays parallel with the ground. If it does not, serious damage can occur

Before lifting, Drop air from suspension •
Just like using a dump trailer, the operator must release the air from the suspension before lifting o This puts the suspension on the stoppers, which makes the trailer much sturdier and less likely to sway when lifted o If air is not released, the lift cylinders will cause the air to be forced from the front air bags, into the rear bags, causing the bogey to go out of parallel with the ground, and could potentially cause serious damage
While lifting, be sure to watch that bogey moves • • •
It is important that either the truck or bogey – whichever has the brakes released – slowly rolls as the tub lifts It is also important to watch that no wheels start to sink, as this can reduce the trailers balance, and place extra strain on lifting components Watch to be sure that the bogey stays parallel with the ground

Review Before lifting the trailer: •
• • • •
•
Release air from the suspension o This ensures that the trailer will be sturdy and reduce sway, as well as to keep the bogey parallel with the ground Be sure brakes are released on either the truck or trailer o This makes bogey movement possible Be sure ground is hard, level, and even Begin lifting As tub raises watch: o Whichever (truck or trailer) has the brakes released, is moving ▪ If the truck brakes are released, it should roll toward the trailer as the trailer lifts ▪ If the trailer brakes are released, it should roll toward the truck as it lifts o The bogey, that the top flange stays parallel with the ground, and that the wheels don’t sink Be sure the tub is all the way back down before moving the trailer, Never move the trailer while raised
