The GO-M04 Gate opener uses a geared action to open or close hopper car gates with a continuous 360° rotation in either clockwise (CW) or counter-clockwise (CCW) direction.
II. SAFETY To prevent injury to yourself or others, and/or damage to equipment, you should adhere to the following basic safety instructions. Read carefully the entire Operator's Guide prior to installing or operating equipment. Always follow proper precautions and use proper tools and safety equipment. Be sure to receive proper training.
III. SUPPLIED MATERIALS The GO-M04 comes shipped unassembled in its carry/storage bag. Prior to assembly, verify that all of the components are present and in good condition. Carrying Case Ratchet Wrench Assembly O-Ring Capstan Drive Fitting Operator's Guide PH: 866.476.9217...
IV. ASSEMBLY Place the Ratchet Wrench Assembly on a clean, flat surface. Place the Capstan Drive Fitting over the Ratchet Assembly's 1-1/2" square drive anvil. Insert Pin (provided) into the Drive Fitting and Wrench's thru-hole. PH: 866.476.9217...

Slide the O-Ring (provided) over the Drive Fitting until it seats into the Fitting's ring-groove. This stops the Pin from coming out. PH: 866.476.9217...
V. OPENING CAR GATES Inspect and prepare the trackside worksite so that it will accommodate the practical and safe use of the GO-M04 Gate Opener. Disengage the Car Gate Locking Mechanism before attempting to open the gate. Failure to disengage the Car Gate Locking Mechanism will damage the Opener.

Continued application of force will damage the Opener. CAUTION Do not use other opening devices (pry bars, multipliers, etc.) in an attempt to "help" the GO-M04 Opener. When the gate is fully open, stop ratcheting and remove the GO-M04 from the car's capstan socket. PH: 866.476.9217...

Opener. CAUTION Do not use other opening devices (pry bars, multipliers, etc.) in an attempt to "help" the GO-M04 Opener. When the gate is fully closed, stop ratcheting and remove the GO-M04 from the car's capstan socket. PH: 866.476.9217...
VII. EXTENSION BARS An Extension Bar can be used to increase the GO-M04's torque output. In fact, the gears inside the GO-M04's ratcheting head are capable of generating up to 5,000 ft-lbs of torque. The addition of an extension Bar introduces a potential hazard if proper safety precautions are not followed.
VIII. SERVICING THE GO-M04 When the GO-M04 is in-for-maintenance and the unit has been disassembled (partial or complete), the components should be cleaned and inspected for wear before reassembly of the Opener. Proper maintenance of equipment often depends upon the ability of a service technician to determine whether a part or assembly is worn to the point where it should be replaced.

APPENDIX B: TORQUE Torque (T) is a "turning" or "twisting" force and differs from tension, which is created by a straight pull. Torque is the result of multiplying the value of the force (F) applied by the Distance from the point of application. The same torque result can be achieved with a lower force if the distance from the point of application is increased.
