There must be at least 60-120ml in the measuring beaker 7 If the manometer indicates large fluctuations during the measurement (12 +/- 4 bar), this is an indication that the pump is faulty. 9 Keep a watch for leaks! The manometer must be observed continuously and the pressure regulated using the valve if necessary. With increasing temperature the pressure also increases, if necessary readjust the pressure to 12 bar. 10 5 60...120 ml 35 30 s Maintenance Checking for leaks and pump pressure (1) 1) Preparation of the machine 1. General disassembly stage 1 (see page 20). 84 2. Open jaw and remove screws (111) on the cover. 83 3. Unscrew ball (80) on the jaw stick (134). 81 4.

The needle on the display must not drop below 12bar in 60 s. 9. Open valve, open jaw (pressure gauge empties). The residual pressure must be released after the test by opening the valve! The pump is permitted to be in operation for max. 50 sec. without an outlet. 2) Check 1. Perform points 1 to 9 on page 35. 2. Jaw stick to the front (the valve on the pressure gauge must be opened). 3. Switch on machine. 4. Leave water to run out for approx. 10 s. 5. Fully close valve. The pressure will rise rapidly initially and stabilise between 16-19 bar (pump pressure check). The pressure will rise slowly due to the temperature increase. 6. Visual and acoustic check on all pressurised connections. The pump must not be in operation for longer than 50 s. System: no leak leak 7.
