Fischer Panda 4000 Generator Set

⚠ Capacitors must be discharged before touching.

Tools: multimeter with capacitor measuring

1. Ensure capacitors are discharged before touching.
2. Visually check for leaking dielectric or capacitor becoming longer.
3. Set multimeter to pass; connect test prods to both capacitor contacts.
4. Observe short beep when charging; reverse poles and observe short beep again.
5. If steady sound or no sound is heard, capacitor is defective and must be replaced.
6. Use capacity measuring instrument to confirm full capacity; replace capacitors not achieving imprinted capacity.

Tools: voltmeter

1. Guarantee that connection to the electrical system is interrupted.
2. Remove all conductors in the power terminal box of the generator.
3. Connect starter battery to generator.
4. Start the generator.
5. Measure voltage between phase(s) and N with a voltmeter.
6. If measured values are substantially below Table E.2.1 values, accept coil damage.

⚠ Never work at the electrical cabinet when the generator is running.

⚠ Do not contact the capacitor before it is discharged.

Tools: isolated screwdriver

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 the cone end of an isolated screwdriver.

⚠ Do not disconnect the battery during operation.

1. Connect positive battery cable directly to solenoid switch of starter; use prepared protective tube.
2. Connect negative battery cable to connection point at engine foot.
3. Install a right-sized fuse in positive battery line as close as possible to battery, maximum 12 inch or 300 mm.
4. Use multi-core stranded wire only; protect cable from heat, vibration and chafing.
5. Check battery cable after installation for possible damage.

1. Fill external cooling water expansion tank with coolant; maximum fill level is max mark; open cover temporarily; keep at least 1/3 coolant during filling.
2. When coolant level no longer drops, disconnect the oil pressure switch.
3. Turn remote control panel on and let coolant pump run for at least 10 minutes.
4. Turn remote control panel off, reconnect oil pressure switch, fill expansion tank to max and close tank.

1. Close the water cock.
2. Release raw water filter from dirt.
3. Beating the filter basket is mostly sufficient.
4. If water seeps through cover, do not seal with adhesive; find cause; replace sealing ring if necessary.

⚠ Lubricating oil should be drained in warm condition.

Tools: spanners, hand pump

1. Open oil drain screw; use a second wrench for countering.
2. Drain oil through oil drain hose; if impossible, use a hand pump.
3. Close oil drain screw again.
4. Open oil filler neck cap.
5. Refill new engine oil.
6. Wait before measuring oil level; oil must settle in the sump.
7. Check oil level with dipstick; level may not exceed Max; 2/3 level recommended.

⚠ A clogged filter causes decreased power output.

1. Clamp the inlet before exchanging the filter.
2. Remove hoses from the used filter.
3. Fasten hoses to the new filter; arrow on filter housing indicates fuel flow direction.

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

Tools: corrosion protection oil, acidless grease, vaseline, Antiseize grease, air dehumidifier

1. Rinse raw water circuit with anti-freeze solution; remove raw water inlet at water cock; suck mixture from container; return leaked cooling water with exhaust to container.
2. Check anti-freeze concentration in internal cooling circuit; adjust to lowest expected temperature.
3. Clean raw water filter and check seal.
4. Check water cock; spray with corrosion protection oil or lubricate with acidless grease.
5. Check all hoses and hose connectors; renew hoses if necessary.
6. Check hose connectors at all raw water valves doubly; protect with double hose clamps if possible.
7. Dismount impeller; check wear; grease with vaseline and store dark; reinstall in spring if good; renew in spring recommended.
8. Check vent valve at raw water inlet; disassemble, check and grease; replace hardened or dirty parts.
9. Check water lock; drain water if rinsed with fresh water to prevent ice damage.
10. Check exhaust/water separator for leakage and hose connectors.
11. Check construction units inside sound cover for leakages; dry cover; find and eliminate cause.
12. During winter storage, take off upper section of sound cover if humidity remains.
13. Spray generator housing and engine housing with corrosion protection oil.
14. Disconnect starter battery positive and negative poles.
15. Lubricate spindle for revolutions adjustment device with Antiseize grease; check cooling water connection block for corrosion; use air dehumidifier.

⚠ Read safety instructions before opening the generator power terminal box with air filter.

1. Stop generator and secure against accidental restart.
2. Open air suction holder by loosening the two quick release fasteners.
3. Pull holder out to change the element.

⚠ Lubrication is very important; the impeller can otherwise dissolve very fast.

Tools: multigrip pliers

1. Close the raw water stop cock.
2. Remove cover of raw water pump by loosening the 4 wing screws.
3. Mark the impeller to ensure correct position at reinstallation.
4. Pull the impeller from the shaft with multigrip pliers.
5. Check impeller for damage and replace if necessary.
6. Lubricate impeller with glycerin or non-mineral oil based lubricant such as silicone spray.
7. Attach impeller to pump shaft; observe marking if reusing old impeller.
8. Fasten cover and use a new gasket.
