The The panel anel is desig esign ned to give ive the oper operat ator or precise cise info inforrmation ion regard arding ing generat erator or operation and current loads. Additionally, should the generator experience a condition necessitating shutdown, a fault code appears on the screen. When running, the the green “RUN” UN ” light should be illuminated. Press P ress the function “FUNC UN C” button to change the display. A green light should appear above the digital readout to indicate the current function. You have a choice of voltage (120 or 240), power (VA), Frequency (HZ), total runtime in hours, and starting battery voltage. P anel programming is explained in section section 5.

The The gener enerat ator or ser serial ial number iden identtifie ifies s you yourr part articu icular lar unit and and is import ortant ant when ord ordering ing parts and accessories. The bar code is used by your dealer and Coast Distribution for warranty administration.
The The ser serial ial number for the KDE5000TA is located on the air inlet plate to the left of the diesel injection pump.
The The ser serial ial number for the KGE KG E5000E 5000E can be found found on a
stainless

shroud
surrounding the alternator the right of the engine.
The The bar cod code is fou found in three locations: locations:
on the generator, generator,
on the packing crate or carton, and on the inside cover of the operator’s manual.

2. SERVICE INFORMATION 2.1 2.1 The importance of prop er servicing
P roper servicing servicing is essential essential to the safety of the the operator and the reliabi reliability lity of the the generator. Any error or oversight made by the technician while servicing can easily result in faulty operation and/or damage to the equipment or injury to the operator.
Warning Improper servicing can cause an unsafe condition that can lead to serious injury or death. Follow the procedures and precautions in this shop manual carefully. Some of the most important precautions are stated below. 2.2 2.2 Important s afety afety precautions
Be sure you have a clear understanding of all basic shop safety practices and that you are wearing appropriate clothing and safety equipment. When performing maintenance or repairs, repairs, be especially careful careful of the following: • Read the instructions before you begin, and be sure you have the tools and skills required to perform the tasks safely. • Be sure that the engine is off before you begin any maintenance or repairs. This will reduce the the possibility possibility of several hazards: - Carbon monoxide poisoning from engine exhaust. - Burns from hot parts. - Injury from moving parts. • Do not run the engine unless the instructions tell you to do so. Keep your hands and clothing away away from rotating rotating parts. • To reduce the possibility of fire or explosion, exercise extreme caution when working around gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep cigarettes, sparks and flames away from all fuel-related parts. 2.3 Service ru les
• Use Us e genuine genuine KIP KIP OR or KIP KIP OR-recom OR -recomm mended part parts s and lubricants lubricants or their equivalent equivalents. s. P arts that do not meet meet Kipor’s Kipor’s design specific specifications ations may damage damage the engine. • Use the special tools designed for the product. • Always install new gaskets, O-rings, etc. when reassembling components. • Clean parts in cleaning solvent upon disassembly. Lubricate any sliding surfaces before reassembly. After reassembly, check all parts for proper installation and operation. • Many screws used in this machine are self-tapping. Be aware that cross-threading or
12
over tightening these screws will strip the threads and ruin the hole. • Use only metric tools when servicing this engine. Metric bolts, nuts and screws are not interchangeable with non metric fasteners. The use of incorrect tools and fasteners will damage the engine. 2.4 Electrical precautions
• Hold the connector body to disconnect the connector. Do not disconnect by pulling the wire harness. To disconnect the locking connector, be sure to unlock first, and then disconnect. • Check the connector terminals for bend, excessive extrusion, missing terminals, or other abnormalities before connecting the connector. • To connect, insert the connector as far as it goes. If the connector is a locking type, be sure that it is locked securely. • Check the connector cover for breakage and check whether the connector female terminal is not opened excessively. Then, connect the connector securely. Check the connector terminal for rust. Remove the rust using an emery paper or equivalent material before connecting the connector. • Set the harness clips in the specified places of the frame securely, and secure the wire harnesses. • Clamp the cables securely. • Clamp the wire harnesses securely so that they do not interfere with the rotating parts, moving parts and hot parts. • Route and connect the wire harnesses properly. Be sure that the harnesses are not slack, twisted or pulled overly taut. • Route the wire harnesses properly so that they do not contact sharp edges and corners and the end of the bolts and screws on the body. • If a wire harness must contact the the end of the bolts or screws or sharp sharp edges and corners, protect the contact part of the harness with a loom or by winding with electrical insulating tape. If the wire harness has a grommet, set the grommet securely. • Take care not to pinch the wire harnesses during installation of a part. If a wire harness has damaged insulation, repair by winding with electrical insulating tape. • When using an electrical tester like a volt/ohm meter or clamp on meter, read the manufacturer’s operating instructions carefully before operating the tester. Be sure that the tester battery is fully charged and the meter is functioning properly

(3) Secure the rotor wit with h a strap strap wrench wrench and tighten tthe he 10mm 10mm flange bolt: tightening tightening torque: 37.5 Lbf (50 N.m) 3.5.4 Stator Installation (1) Before installing a new stator, check the resistance values of the new part. (2) Adjust the spacing between the stator and rotor. • Insert a feeler gauge between the stator winding and the projection of the rotor. • Rotate the rotor one complete revolution. • Secure the flange bolt connecting stator and front end cover. The locking torque is 7.5
