With the hydraulic kit installed on this vehicle, it may be operated as normal.
Never operate the vehicle if the Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating Front or Rear (GAWR), or the wheel or tire load ratings are exceeded.
Refer to the Railgear Kit Operation, Service and Parts manual for information on the
mechanical operation, service and parts of the railgear.
Operation of Standard Railgear Hydraulic System Controls:
The railgear hydraulic system consists of a hydraulic pump and manifold, a front control box
and a rear control box.
The railgear hydraulic system must be energized prior to use by turning on the respective
dash switch. At this point the dash switch light should come on but the pump should not run
and the railgear should not move until a control button is depressed.
The direction of the front or rear railgear movement is selected by pushing the “Up” or
“Down” button on the respective control box located near the railgear. At this point the
pump should start and the railgear should move in the selected direction.
To stop the movement of the railgear, release the depressed button or return the handle to
the middle position.
The pump must be de-energized after use by turning off the respective dash switch. At this
point the pump should not be able to run and the control buttons should be in-active.
Operation of the Emergency Hand Pump:
If the railgear hydraulic system should fail such that the railgear does not respond to
depressing the buttons on the front and / or rear control boxes, then the emergency hand
pump system may be used to place the vehicle on rail or remove the vehicle from rail. Follow
the standard operation procedure (as detailed in the Railgear Kit Operation, Service and Parts
Manual) except substitute the following steps when the procedure requires raising or lowering
of the railgear.
1.
Remove the hand pump handle from storage and insert the handle into the hand pump
located on the body of the hydraulic pump.
2.
There are four manifold directional valves, one for each railgear function: “Front Gear
Up”, “Front Gear Down”, “Rear Gear Up”, and “Rear Gear Down”. The manual over-rides
for these valves are located on the manifold under rubber boots. Only open one manifold
directional valve over-ride at a time. To manually open a manifold directional valve over-
ride, remove the rubber boot, push in and twist the knob allowing the knob to extend. To
manually close a manifold directional valve over-ride, push the knob in, twist the knob to
lock it in place and replace the rubber boot.
