Fischer Panda Panda_4000s SC PMS Generator Set

Tools: voltmeter

1. Guarantee connection to electrical system is interrupted.
2. Remove all conductors in generator power terminal box.
3. Connect starter battery to generator.
4. Start generator.
5. Measure voltage between phase(s) and N with voltmeter.
6. If values are substantially below Table 8.2.1, accept coil damage.

1. Locate fuel solenoid valve in front of injection pump.
2. Remove small retention screw and plug from solenoid for a short period while operating.
3. Replace plug immediately.
4. Motor should react immediately by revving high.
5. If motor does not react sharply, solenoid valve may be faulty.

⚠ Do not seal leaking cover with adhesive or sealant; find cause.

1. Close water cock before opening filter.
2. Release filter from debris.
3. Beat filter basket; mostly sufficient.
4. If water seeps through cover, replace sealing ring.

⚠ Never check capacitors while generator motor is running. Charged capacitors can be lethal.

Tools: insulated screwdriver, discharge reactor 5-10 kOhm, multimeter with capacitor measuring

1. Switch off generator.
2. Disconnect starter battery.
3. Open generator power terminal box and remove caps.
4. Short circuit the two capacitor contacts using insulated screwdriver cone end.
5. For three-phase capacitors discharge between every phase L1-L2, L2-L3, L1-L3.

⚠ Lubricating oil should be drained in warm condition.

Tools: spanner, oil drain pump if needed

1. Lead oil drain hose through sound cover.
2. Open oil drain screw; use a second wrench to counter.
3. Drain engine oil; oil should be drained warm.
4. Close oil drain screw.
5. Open oil filler neck and refill engine oil.
6. Wait briefly for oil to settle.
7. Check oil level on dipstick; recommended 2/3, do not exceed Max.

Tools: flat head screwdriver

1. Rotate closures roughly 180° counter-clockwise with flat head screwdriver.
2. Pull sidewalls out by gripping into slots.

1. Open air suction holder by loosening two quick release fasteners.
2. Pull holder out to change element.
3. Install new element and close holder.

⚠ A clogged filter causes decreased power output.

1. Clamp fuel inlet before exchanging filter.
2. Remove hoses from used filter.
3. Fasten hoses to new filter.
4. Observe arrow on filter housing for fuel flow direction.

⚠ Impeller may dissolve quickly if installed incorrectly.

Tools: multigrip pliers, wing screw wrench

1. Close raw water stop cock.
2. Remove pump cover by loosening four wing screws.
3. Pull impeller from shaft with multigrip pliers.
4. Check impeller for damage and replace if necessary.
5. Lubricate impeller with glycerin or non-mineral oil/silicone spray.
6. Mark impeller for correct reinstallation.
7. Reinstall impeller in correct position.
8. Fasten cover with a new gasket.

1. Before first start, turn engine once by hand.
2. Change engine oil and engine oil filters.
3. Reintegrate impeller and check pump for leakage.
4. Charge starter battery, connect cables, check battery voltage.
5. Start generator and check voltage, speed regulation etc.
6. Check all switching off devices for function.

⚠ Maximum fill level is the max mark.

1. Ensure generator is aligned horizontally to all sides.
2. Fill external expansion tank with coolant to max mark.
3. Temporarily open cover of external expansion tank.
4. Ensure at least 1/3 coolant remains in expansion tank during filling.
5. When coolant level stops dropping, disconnect oil pressure switch.
6. Turn remote control panel on and let coolant pump run at least 10 minutes.
7. Turn panel off, reconnect oil pressure switch, fill expansion tank to max, close tank.

1. Use lever on fuel pump.
2. Pump by hand until counter pressure becomes noticeable.
3. This builds primary pressure and accelerates venting.
