8.7. How to vent the hydraulic cylinders

Venting the hydraulic cylinder is not required, if
- the hoses have been disconnected from the quick-action couplings at the control unit
because the remaining oil in the hose is being kept by valves and for this reason no air
can enter.

The hydraulic cylinder must be vented if
-
there has been too little oil in the tank and air has been attracted.
-
there were leaky spots at the hoses or in the connections.
-
the hoses were unscrewed from the basic machine.

Eliminate the cause of the air entrance.

Open the machine completely.

First unscrew the lower „vent screw for closing“.

Connect the transparent venting hose and insert it in the collecting vessel of the aggregate.

Close until there is no more air visible in the venting hose, then tighten again the vent
screw.

Close the machine completely.

Unscrew the lower „vent screw for opening“.

Connect the transparent venting hose and insert it in the collecting vessel of the aggregate.

8.8. Protect machine parts against corrosion
In case of air humidity of > 85 % and / or high temperatures you must treat the untreated steel
parts of the machine with anti-corrosive protecting agent (e.g. AVILUB NCI 9840).
