Service / Repair. Dismounting of cabinet rear part on following variants: C 100.7 - C 105.7 - C 110.7 - C 120.7 - C 120.7 X-TRA 1. Tools: Screwdriver PH2 2. Remove the 2 screws (Long) fixing the handle 3. Remove the 6 screws (Short) from the rear side (fig. 3) 4. Don’t remove the accessory bracket and the wheels 5. The cabinet rear part can be removed and there is now access to the motor pump unit Fig. 1 Fig.
D Service / Repair. Dismounting of cabinet rear part on following variants: C 125.7 - C 125.7 X-TRA 1. Tools: Screwdriver PH2 2. Remove the 2 screws (Long) fixing the handle (fig. 3) 3. Remove the 6 screws (Short) from the rear side (fig. 4) 4. Don’t remove the accessory bracket 5. Remove the wheels and remove the 2 screws behind the wheel parts (fig. 5) 6. The cabinet rear part can be removed and there is now access to the motor pump unit Fig. 3 Fig. 4 Long screws Short screws Fig.
D Service / Repair. Dismount / mounting of switch box cover and switch box. 1. Remove the 2 screws . Fig 1 2. Release the snap on switch box form the hook on the switch box cover. Fig 2 3. Release the hook on the switch box from the snap on the switch box cover by using a small ordinary screw driver and remove the switch box cover Fig 3 4.
Service / Repair. Dismounting / mounting of the start / stop valve. Fig 1 is showing how the start / stop valve must be assembled. A special tool is needed in order to take out the seat of the start / stop valve (fig 2) Please use “Puller for valve seat M4” item number 31000189. NOTE: the valve seat is no longer usable after using the puller. Fig. 1 Fig.
D Service / Repair. Dismounting / mounting of water / oil seal and valves. To change the oil seals, water seals and pressure valve, use a screw driver to dismount the parts (fig 3 & 4). Alternatively there is a puller number 1220103 to pull out the valves seats (pressure and suction valves. Note: the seat is no longer usable after using the puller Cleanup and lubricate before mounting! Fig 1 is showing the pump after opening the cylinder head from the cylinder block.
D Service / Repair. IMPORTANT mounting information: In order to optimize the self suction mode the valve bodies must be positioned correct according to the water canals inside the cylinder head. The “leg” of the valve body must not be placed in front of a canal. Fig 1 is showing the WRONG positioning and fig 2 is showing the CORRECT positioning. Fig. 1 Fig.
D Service / Repair. Precaution when assembling the switch box. 1. Ensure that the cable and the 2 wires are mounted in the groves Fig. 1 Precautions when assembling the machine. 1. Ensure that the gasket for the water inlet is mounted correctly inside the front part before mounting the motor pump unit in the front part Fig. 2 2. Ensure the power cable is not placed on the internal ribs before assembly Fig. 3 3. Ensure the cable relief is mounted correctly Fig. 3 Fig. 2 Fig. 1 Fig.
D Service / Repair. Assembly of cabinet rear part on following variants: C 125.7 - C 125.7 X-TRA 1. Tools: Screwdriver PH2 Fig. 3 2. Note that screws has different lengths: Short type:8 pcs Long type 2 pcs ( for handle): 3. Mount 2 short screws behind the wheel parts (fig. 5) 4. Ensure that the wheels are mounted correctly by sliding the parts together, before mounting the screws Fig. 6 5. Mount the wheels and mount 6 short screws on rear side (fig. 4) 6.
