This is also valid, if you only refill partial quantities. Close the tank filler with the filler and breather cap. Remove any leaking hydraulic oil by means of the cleaning cloths. Always dispose of contaminated cleaning cloths according to the rules.
The oil tank is now refilled.
In order to confirm the actual oil level of the hydraulic unit, the hydraulic fluid must circulate in the system by means of the pump for about 20 minutes. During this, the oil is filtered through the optional line filter. After the time elapsed, the oil level is to be checked again and hydraulic oil is to be refilled, if necessary.
Switching on the power supply Connect the power plug to the socket (230 V). Switch the main switch provided on the operating module from “0” to “1”. Check the circuit after the first switch-on for leakages.

Notes
8 Operation If, during operation or inspection, any irregularities, deviations, defaults, or wear are noticed, you must in any case: immediately switch off the training system. examine the cause and remedy the default. replace the defective component. no longer put into operation the training system, if applicable.
All safety devices must be operational and complete. The unit must only be switched on, after the hose lines P and T were connected to the unit. Otherwise, there is a risk of quick heating of the unit and thus of damage to the pump. The unit was developed for the short-term duty cycle S3 only. After a duty time of 15 minutes at most, plan a resting period of about 30 minutes. After each exercise, the unit must be switched off.
Switching on
Prior to every switch-on, check the hydraulic fluid level. Before switching on the unit, check the hose and hose connections. Switch the main switch provided on the control unit from “0” to “1”.
Pressure relief Before and after each exercise, the unit must be depressurized. There are three possibilities to do this:
Depressurization on the pressure control valve
Depressurize the adjusting spindle by turning it completely to the left.
The connection P to T is depressurized.
Depressurization on the directional control valve The data spec

Notes
9 Maintenance and Servicing Report any errors you detect to your superior in order for them to be repaired as quickly as possible. Note that small errors may turn into great errors, if they are not repaired in time. Clean plastic components only with a slightly humid cloth! Use only water and, if need be, a soft cleaning agent without chemical additives. Never use solvents or aggressive cleaning agents! Before using the cleaning agent, consult the operating instructions and the DIN material safety data sheet for its scope of application and possible risks. Never blow off dust from the training system with the help of compressed air, since this could damage sensors and valves of the function modules. If you have to remove oil, use appropriate binding materials and cleaning cloths! Protect the training system from dust and humidity so as to make sure that it does not contaminate and that you can use it for a long period of time.
