dustment Instructions Raise djustment Port Face Lock Nut D D F E F Upper Valve Section Relief artridge Lower djustment ap Hex Key Figure Raise djustment Figure.) Raise Leveling djustment 3.) Set Lower Relief Valve:.) Start with the bucket flat on the ground and raise the boom to full height with the engine at low rpm. If the bucket is tilted forward when the boom is at full height, lower the boom and adjust the raise adjustment screw IN. If the bucket is tilted back when the boom is at full height, adjust the raise screw OUT. (Typically / turn is a good increment of change.) When the bucket is level through the raise cycle proceed to step..) Recheck the raise cycle at high engine rpm starting with the bucket flat on the ground and raising the boom to full height. The bucket should be level when the boom is at full height. If the bucket is tilted back slightly when the boom is at full height, the raise unloading spool metering notch may be too restrictive or the unloading spool relief feature may be set too low. high flow spool and/or a heavier unloading spool spring will correct this problem..) Lower Leveling djustment.) Start with the boom in the fully raised position and the bucket parallel to the ground and lower the boom with the engine at low rpm. If the bucket is tilted forward with the boom on the ground, adjust the lower adjustment screw OUT. If the bucket is tilted back with the boom on the ground, adjust the lower adjustment screw IN. (Typically / turn is a good increment of change.) When the bucket is level through the raise cycle proceed to step..) With no load in the bucket, raise the boom to an intermediate height and fully curl the bucket. Lower the boom. If the boom does not lower, the lower relief valve setting must be reduced.* If the relief valve is adjustable, loosen the lock nut and turn the adjustment screw OUT. (Typically /4 turn is a good starting point.) When the boom begins to lower at a reasonable rate, hold adjustment screw in position and tigthen lock nut..) Recheck the relief setting with a full load in the bucket. Start with the boom at full height with the bucket parallel to the ground then lower the boom to the ground. The bucket should be level with the ground. If the bucket is tilted slightly forward, the relief valve is set too low.* If the relief valve is adjustable, loosen the lock nut and turn the adjustment screw IN. (Typically /4 turn is a good starting point.) *Note: n adjustable relief valve is provided for initial prototyping and qualification of the valve. Once the valve has been configured and all settings are fixed, a non-adjustable relief valve can be used for cost savings..) Recheck the lower cycle at high engine rpm starting with the bucket parallel with the boom at full height then lowering to the ground. If the bucket is tilted forward slightly when the boom is on the ground, unloading spool metering notch may be too restrictive or the lower relief valve may be set too low. high flow spool and/or a higher relief valve setting will correct this problem. 6
Troubleshooting Symptom System does not level correctly in the raise and/or lower function. Under load, bucket dumps when boom is actuated. Valve causes instability/vibration in the system. Leveling hesitates at beginning of operating cycle. causes system to freeze or halt downward motion when bucket cylinder becomes fully retracted. Problem Valve is not adjusted properly. Pressure balancing orifice in flow divider spool is plugged with debris. Flow divider spool is damaged. Flow divider spool is sticking/stuck. Dual Self-Level valve relief valve setting is set too low. Flow split is incorrect. Valve has come out of adjustment. Relief valve is set too high. Machine is overloaded. Machine flows are too high for the valve s capability. ir has become trapped in the system. Flow divider spool is sticking. relief valve setting is set too high. Solution djust leveling adjustments screws as outlined on page 6 (djustment Instructions). Remove flow divider spool, clean and replace. hange oil and filter in system. Remove and replace flow divider spool. Remove flow divider spools from valve, clean valve and flow divider spools and reassemble. If adjustable, increase the spring load by tightening the adjustment screw. If not adjustable, see an Eaton distributor and order a relief valve with a higher relief setting. djust leveling adjustments screws as outlined on page 6 (djustment Instructions). If adjustable, decrease the spring load by loosening the adjustment screw. If not adjustable, see an Eaton distributor and order a relief valve with a lower relief setting. Match job to machine s capabilities. Run machine at lower RPM. ycle the system several times to expel air from that system. Remove flow divider spools from valve, clean valve and flow divider spools and reassemble. If adjustable, increase the spring load by loosening the adjustment screw. If not adjustable, see an Eaton distributor and order a relief valve with a lower relief setting. 7
