High-quality air hose: 1/2" ID, preferably fitted with a Universal (Chicago type) Coupling.

  • Page 7: Pre-Start Checklist

    IV. PRE-START CHECKLIST The GO-A3-PW comes shipped fully assembled. The handle assembly is adjustable to meet an operator's individual needs. To raise or lower the height of the handle assembly, loosen both handle set-screw knobs located opposite each other on the inside of the handle frame.
  • Page 8 When the handle assembly is in the desired position, re-tighten all six (6) bolts. Verify that the bolt which secures the Capstan Drive Fitting is tight. Fill the GO-A3-PW's Lubricator with recommended oil: WORKMASTER's TOOL-LUBE ™ Air Tool Oil PN: 36-21010.
  • Page 9 Secure hose couplings with safety pins, clips, cables or chains. Each day, before opening any railcar gate, operate the GO-A3-PW, for about 1-minute. This will allow oil to coat the Gear Motor's internal components. PH: 267.350.2809...

  • Page 10: Opening Car Gates

    V. OPENING CAR GATES Roll the GO-A3-PW Opener up to the hopper gate until you "rough spot" position the opener's output drive with the railcar gate's capstan socket. Using the Capstan Swaging Kit (optional accessory, PN: 33-11120), clean-out and square-up the capstan socket on the car gate so that the Capstan Drive Fitting on the Gear Motor's output drive can be aligned properly, and fully seated in the railcar gate's capstan socket.
  • Page 11 Outriggers must be extended before operating the Opener. The reaction force produced by the Gear Motor will cause the GO-A3-PW to roll over if Outriggers are not properly extended. Outriggers must be slid back into the retracted position when Opener is not in use, eg, travel or storage.
  • Page 12 Pivot the GO-A3-PW's wheels 90º by turning the pivot wheel lever to the right. To open the railcar gate, grip the Opener's handle with both hands. Move the Throttle Lever to the desired position. PH: 267.350.2809...
  • Page 13 Throttle Lever up towards the operator. counter-clockwise rotation (operator's perspective) push the Throttle Lever down, away from the operator. The GO-A3-PW produces torque for slowly and deliberately opening railcar gates. It is not designed for rapid direction change of gears.
  • Page 14 "help" the GO-A3-PW Slide Outriggers back into the frame assembly, put pivot wheels into the straight position, and roll the GO-A3-PW back from the railcar, thereby disengaging the Capstan Drive Fitting from the railcar's capstan socket.

  • Page 15: Closing Car Gates

    VI. CLOSING CAR GATES Roll the GO-A3-PW Opener up to the hopper gate until you "rough spot" position the Opener's output drive with the Railcar Gate's Capstan Socket. Disengage the Car Gate Locking Mechanism before attempting to open the gate.
  • Page 16 Outriggers must be extended before operating the Opener. The reaction force produced by the Gear Motor will cause the GO-A3-PW to roll over if Outriggers are not properly extended. Outriggers must be slid back into the retracted position when Opener is not in use, eg, travel or storage.
  • Page 17 Pivot the GO-A3-PW's wheels 90º by turning the pivot wheel lever to the right. To close railcar gate, grip the Opener's handle with both hands. Move the Throttle Lever to the desired position. PH: 267.350.2809...

  • Page 20: Height Adjustment

    VII. HEIGHT ADJUSTMENT The height of the GO-A3-PW Gate Opener's Drive Shaft can be adjusted to help align the Capstan Drive Fitting with the capstan socket. By rotating the handle, centered at the top of the GO-A3-PW frame, the Drive Shaft can be more precisely aligned with the capstan socket.

  • Page 21: Maintenance & Storage

    If excess moisture is allowed to collect within the CAUTION motor, rusting may occur, and this contamination will not allow the motor to function. When not in use, the GO-A3-PW should be stored in a clean, dry and sheltered area, safely out of the way. PH: 267.350.2809...
  • Page 22 The GO-A3-PW should be maintained before being stored. IMPORTANT If the GO-A3-PW is going to be stored for an extended period of time (e.g. 60+days), it must be prepared for storage To prep the unit: Disconnect both hoses feeding the air motor Pour 12-15 drops of high detergent 30W motor oil into each open port.
  • Page 23 Failure to drain oil will cause the air motor to stall. If you have stored the GO-A3-PW for an extended period of time and have not followed the previous steps you will need to lubricate the inside of the air motor prior to start-up.
