KIT-SEAL 4479741 - Caterpillar

Note: A machine with ride control may experience partial lowering of the lift arms when the lever is held in the DUMP position with the bucket against the bucket stops and the lift arms are fully raised. To avoid partial lowering of the lift arms, return the lever to the HOLD position. An optional feature can be enabled to help prevent this situation. Enable Dump Stop Snubbing by using the Monitoring System Display. Refer to the Operation and Maintenance Manual, "Monitoring System" “Settings” section for details about the Dump Stop Snubbing control.Description for Snubbing
Note: Snubbing occurs with the lift and the tilt functions.As the lift linkage is moved to the full raise or full lower position, the control system will cushion the end of travel. This control may be overridden by moving the lift lever to the HOLD position. Then move the lever back to the same direction from which the lever was released.If desired, the end of travel cushioning may be disabled by your Cat dealer.As the bucket is moved to the full tiltback or full dump position, the control system will cushion the cylinder at the end of travel. The control system will also cushion the linkage at the tilt back stops and at the dump stops. This control may be overridden by moving the lift lever to the HOLD position and then moving the lever back to the same direction. This procedure allows for bucket cleanout or banging on the dump stops. The bucket must be tilted back to approximately 10 degrees to reenable dump stop cushioning. The end of travel cushioning may be disabled by your Cat dealer.3rd Auxiliary Hydraulic Function (If Equipped)
Move the control to the forward position to pressurize the right supply line.Move the control to the back position to pressurize the left supply line. The thumb wheel also has a detent.Move the control to the center for the HOLD position.Note: With the continuous flow function on and set, moving the 3rd function control into the maximum (detent) position will send the set flow to the appropriate line. With the maximum flow set and continuous flow off, the 3rd auxiliary function will be limited to the set maximum flow.4th Auxiliary Hydraulic Function (If Equipped)
Move the control to the forward position to pressurize the right supply line.Move the control to the back position to pressurize the left supply line. The 4th function control also has a detent.Move the control to the center for the HOLD position.Note: With the continuous flow function on and set, moving the 4th function control into the maximum (detent) position will send maximum flow to the appropriate line. Unlike 3rd function, 4th function maximum flow cannot be adjusted through the display.Continuous Flow Control (If Equipped)
