Figure 251. Quick attach pins (shownin engaged position)3. Engaged position2. Disengaged positionIf you do not fully seat the quick attach pinsthrough the attachment mount plate, theattachment could fall off of the traction unit,crushing you or bystanders.Ensure that your quick attach pins are fullyseated in the attachment mount plate.Connecting the Hydraulic HosesIf the attachment requires hydraulics for operation,connect the hydraulic hoses as follows:1. Stop the engine.2. Move the auxiliary hydraulics lever forward,backward, and back to neutral to relieve pressureat the hydraulic couplers.3. Move the auxiliary hydraulics lever into the reverseposition.4. Remove the protective covers from the hydrauliccouplers on the traction unit.5. Ensure that all foreign matter is cleaned from thehydraulic connectors.6. Push the attachment male connector into the femaleconnector on the traction unit.Note: When you connect the attachment maleconnector first, you will relieve any pressure built upin the attachment.Hydraulic fluid escaping under pressure canpenetrate skin and cause injury. Fluid injectedinto the skin must be surgically removed withina few hours by a doctor familiar with this formof injury or gangrene may result.• Keep your body and hands away from pinhole leaks or nozzles that eject high pressurehydraulic fluid.• Use cardboard or paper to find hydraulicleaks, never use your hands.Hydraulic couplers, hydraulic lines/valves, andhydraulic fluid may be hot. If you contact hotcomponents you may be burned.• Wear gloves when operating the hydrauliccouplers.• Allow the traction unit to cool beforetouching hydraulic components.• Do not touch hydraulic fluid spills.7. Push the attachment female connector into themale connector on the traction unit.8. Confirm that the connection is secure by pullingon the hoses.9. Move the auxiliary hydraulics lever to neutral.Removing an Attachment1. Lower the attachment to the ground.2. Stop the engine.3. Disengage the quick attach pins by turning themto the outside.4. If the attachment uses hydraulics, move the auxiliaryhydraulics lever forward, backward, and back toneutral to relieve pressure at the hydraulic couplers.5. If the attachment uses hydraulics, slide the collarback on the hydraulic couplers and disconnect them.24
