7.5. Used
hydraulic
oil
Only use
HLPD 32
.
Features: protection against corrosion, resistance to ageing, abrasion-reducing additives, high
carrying capacity and particulary water retending.
The hydraulic oil has to be handled properly and to be disposed of.
7.6. Checking the hydraulic oil level
Remove the red screw at the top of the aggregate.
Take out the oil dip rod, clean it and insert it again.
Take out the oil dip rod again and check the oil-level. It must be between the two markers.
If the oil level is below the lower mark, then you need to refill the hydraulic oil HLPD 32.
7.7. Venting the hydraulic cylinders
Venting the hydraulic cylinder is not required, if
the hoses have been disconnected from the connection at the control unit because the
remaining oil in the hose is being kept by valves and for this reason no air can enter.
Venting of the hydraulic cylinder is necessary, if
there has been too little oil in the tank and air has been attracted.
there were leaky parts in the hoses or connections.
the hoses were unscrewed from the WI PRECISION
®
basic machine.
Eliminate the cause of the air entrance.
Open the machine completely therefore press button <
>.
First loosen the lower venting screw (Z1) for closing (lefthand side).
Connect the transparent venting hose and insert into tank of WI FORCE
®
hydraulic
aggregate or into the collecting vessel.
Close until there is no air in the venting hose with button <
>.
Then screw on the venting screw (Z1).
Than loosen lower venting screw (A1) for opening (righthand side).
