Maintenance Manual for the Hydraulic Resistance Disposer for the Operator
Basically, the damper is kept clear with its sliding surfaces of gross pollution. The sliding surface of the piston rod is to
be exempted on a regular basis to remove dirt and dust residue. After cleaning it is recommended to treat the sliding
surface with suitable lubricants from the manufacturer. The proper lubricant can be obtained from proxomed.
The damper cannot be cleaned with harsh detergents. When cleaning, make sure that the caps of the valves are
unscrewed.
Dilutions and aggressive cleaning agents can damage the surfaces, seals and stickers of the damper and
may not be used. (alcohol, acetone, brake cleaner, etc.)
The surfaces of the damper are made of anodized aluminum and then react to UV light, which can lead to slight color
changes. Particularly in the area of stickers and hidden areas, this effect can lead to color shade. The function of the
damper is not affected.
Check-up and filling of the system pressure
The hydraulic unit operates with an air spring that biases the oil column with a floating piston. The filling valve is
normally protected at the front part with a protective cap.
Before checking and / or filling of the system pressure it is suitable to wear goggles and to expand the
damper.
Steps for filling and check-up:
-
Carefully remove the cap
-
Unscrew the pump with suitable tools
-
Check the pressure! Set pressure
= 2 - 3.5bar!
-
If pressure is < 2 - 3.5 bar, re-inflate up to set pressure.
-
Carefully remove the pump again.
-
Screw the cap
