1. 7 Commissioning NOTE With the LUKAS hand pump a little idle stroke may occur when the unit is first used in the high pressure range However this idle stroke independently stops after a device is operated 2 3 times ATTENTION The hand pump should be as close to horizontal as possible because otherwise the usable amount changes The oil fill plug must always be unscrewed one turn before starting operation of the hand pump This enables the aeration and bleeding of the hydraulic tank After the work is completed but before transport the oil fill plug should be retightened 7 1 Unlocking the pump Unlock 1 the shipping lock of the pump by sliding the locking pin in the direction of the hand wheel until it comes against the stop To lock 2 the pin move it until it comes against the stop in the other direction To do this the lever must be in the home position at the tank 7 2 Retracting the handle You can pull out the handle by applying pressure to both sides of the thrust piece and simultaneously pulling in the direction of the handle end until the thrust piece re engages Pi 7 3 Bleeding the pump 1 Open the discharge valve 2 Open the oil fill screw plug on the tank container and check the oil fill level The oil fill level should come up to approximately 1 2 cm below the top edge of the oil reservoir 3 In this state work the pump handle several times NOTE To bleed connected equipmen2. Execution Place the hand pump on a solid base to operate Then connect a test manometer to the supply hose line Release the pump lever lock and close the discharge valve Then the pressurisation to operating pressure corresponding to the specification on the identification plate occurs NOTE In this test an idle time of approximately 2 minutes needs to be observed and the hand pump needs to be reloaded to operating pressure The resulting max operating pressure must not drop by more than 5 after 10 seconds A test pressure gauge is available from the LUKAS line of accessories 10 3 Hydraulic fluid change or adding hydraulic fluid The hydraulic fluid should be changed if dirty at least once a year When the hand pump is operated in an especially dusty environment we recommend changing the fluid at least once every half year ATTENTION Add hydraulic fluid only if the hand pump is disconnected from the lines or the equipment operated with the pump is hydraulically depressurised Otherwise after filling the entire hydraulic system could contain more hydraulic fluid than the tank can hold Procedure 1 Open the bleed fill cap on the tank 2 Add hydraulic fluid until the fluid level comes up to 1 2 cm below the top edge of the oil tank 3 Bleed the hand pump as described in the chapter bleeding the pump 4 Check the fluid level again and close the tank again at the correct fluid level with the vent fill cap
