Operate the machine and check coupler cylinder hose slack with the bucket cylinder fully extended and fully retracted. If there is not enough slack in either position, loosen the hose clamps. Adjust the hoses as outlined in the following step.
Pull the slack out of the hoses from the top fittings to the top clamp. Tighten the top clamp. Measure the hoses between the points listed below and adjust the hoses to the listed distances.
H to K = 570 mm (22.4 inch)
J to K = 330 mm (13.0 inch)
L to M = 600 mm (23.6 inch)Once the hoses are properly adjusted, tighten the lower clamp and the cable strap. It is critical for the hoses to be adjusted properly to keep enough slack at the front flex joint.
