6. Now mount the small hinge pin (3) and the second sleeve (4) with two hex
screws (1) above the larger hinge pin.
7. Hook the large borehole of the support arm (8) in the small hinge pin and
secure the joint with a pin (6).
8. Adjust the upper sleeve in such a way that the distance between the hinge of
the support arm (8) and the square tube arm (7) is exactly 380 mm.
9. Tighten all screws on the sleeves with at least 70 Nm.
10. Now attach the support arm (8) to the square tube arm (7).
11. First place the stabilising sleeve (5) inside the square tube arm in height of
the front drill hole.
The sleeve avoids deforming of the tubes by the screw clamping force.
12. Push a hex screw (1) through the borehole in the support arm and through
the drilling in the square tube arm and tighten it.
The screw (1) must be guided through the drillings of the swing arm and
square tube arm and also through the stabilising sleeve (5).
Operation
After installation and before first use, take absolutely some test runs. Start out
without load and gradually work up to the highest load, which is determined by the
maximum load of the arm or the winch.
Monitor while test running, if the construction of the swing arm is up to its load
and check, if the screw connections are fitted firmly.
Cleaning and Maintenance
Do not expose the swing arm continuously to moisture.
To keep the hinges well lubricated, regularly apply grease.
