Important Safety Information: 1
CHAPTER1 IMPORTANT SAFETY
INFORMATION
Read this manual and the operation and safety instructions included with your implement and/or controller
carefully before installing the TC1™ system.
• Follow all safety information presented within this manual.
• If you require assistance with any portion of the installation or service of your Raven equipment, contact your
local Raven dealer for support.
• Follow all safety labels affixed to the TC1 system components. Be sure to keep safety labels in good condition
and replace any missing or damaged labels. To obtain replacements for missing or damaged safety labels,
contact your local Raven dealer.
When operating the machine after installing TC1, observe the following safety measures:
• Be alert and aware of surroundings.
• Do not operate TC1 or any agricultural equipment while under the influence of alcohol or an illegal substance.
• Remain in the operator position in the machine at all times when TC1 is engaged.
• Disable TC1 when exiting the operator seat and machine.
• Do not drive the machine with TC1 enabled on any public road.
• Determine and remain a safe working distance from other individuals. The operator is responsible for disabling
TC1 when the safe working distance has diminished.
• Ensure TC1 is disabled prior to starting any maintenance work on TC1 or the machine.
• Do not use hands to check for leaks. Hydraulic fluid under pressure can penetrate the skin and cause serious
injury or death.
• When starting the machine for the first time after installing TC1, be sure that all persons stand clear in case a
hose has not been properly tightened.
• The machine must remain stationary and switched off during TC1 installation or maintenance.
NOTICE
WARNING

2 TC1/HDU Installation Manual for Buhler Versatile Row Crop Steer-Ready (MY2015 & Newer)
HYDRAULIC SAFETY
• Raven Industries recommends that appropriate protective equipment be worn atall times when working on the
hydraulic system.
• Never attempt to open or work on a hydraulic system with the equipment running. Care should always be
taken when opening a system that has been previously pressurized.
• When disconnecting the hydraulic hoses or purging is required, be aware that the hydraulic fluid may be
extremely hot and under high pressure. Caution must be exercised.
• Any work performed on the hydraulic system must be done in accordance with the machine manufacturer
approved maintenance instructions.
• When installing TC1 hydraulics or performing diagnostics, maintenance, or routine service, ensure that
precautions are taken to prevent any foreign material or contaminants from being introduced into the machine
hydraulic system. Objects or materials that are able to bypass the machine hydraulic filtration system will
reduce performance and possibly damage the TC1 valve.
ELECTRICAL SAFETY
• Always verify that the power leads are connected to the correct polarity as marked. Reversing the power leads
could cause severe damage to the equipment.
• Ensure that the power cable is the last cable to be connected.

PREPARING FOR INSTALLATION
Before installing the TC1 system, park the machine where the ground is level, clean, and dry. Bleed pressure from
the hydraulic system and leave the machine turned off for the duration of the installation process.
During the installation process, follow good safety practices. Be sure to carefully read the instructions in this
manual as you complete the installation process.
• Ensure the machine hydraulic filters have been recently changed and there are no issues with the machine
hydraulic system (e.g., pump issues, faulty hydraulic motors, fine metal deposits in the hydraulic hoses, etc.).
• Ensure the machine hydraulic system is using fresh oil and debris is flushed from the hydraulic hoses, valves,
and filters.
Raven Industries recommends the following best practices when installing the TC1 system:
• Use part numbers to identify the parts.
• Do not remove the plastic wrap from a part until it is necessary for installation.
• Do not remove plastic caps from a part until it is necessary for installation.
