2. SERVICE INFORMATION2.1 The importance of proper servicingProper servicing is essential to the safety of the operator and the reliability of the generator. Any erroror oversight made by the technician while servicing can easily result in faulty operation and/or damage tothe equipment or injury to the operator.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.c.Some of the most important precautions are stated below.ms,In2.2 Important safety precautionsSysteBe sure you have a clear understanding of all basic shop safety practices and that you are wearingappropriate clothing and safety equipment. When performing maintenance or repairs, be especiallycareful of the following:Read the instructions before you begin, and be sure you have the tools and skills required toperform the tasks safely. Be sure that the engine is off before you begin any maintenance or repairs. This will reduce thepossibility of several hazards:KiporPower 2011- 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 handsand clothing away from rotating parts. To reduce the possibility of fire or explosion, exercise extreme caution whenworking around gasoline. Use only a nonflammable solvent, not gasoline, to cleanparts. Keep cigarettes, sparks and flames away from all fuel-related parts.6
2.3 Service rulesUse genuine KIPOR or KIPOR-recommended parts and lubricants or their equivalents. Parts thatdo not meet Kipor’s design specifications may 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 beforereassembly. 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 overtightening these screws will strip the threads and ruin the hole. Use only metric tools when servicing this engine. Metric bolts, nuts and screws are notinterchangeable with non metric fasteners. The use of incorrect tools and fasteners will damagethe engine.Electrical precautionsSys2.4tems,Inc. Hold the connector body to disconnect the connector. Do not disconnect by pulling the wireharness. To disconnect the locking connector, be sure to unlock first, and then disconnect. Check the connector terminals for bend, excessive extrusion, missing terminals, or otherabnormalities before connecting the connector. To connect, insert the connector as far as it goes. If the connector is a locking type, be sure that itis locked securely. Check the connector cover for breakage and check whether the connector female terminal is notopened 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 wireharnesses. Clamp the cables securely. Clamp the wire harnesses securely so that they do not interfere with the rotating parts, movingparts 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 theend of the bolts and screws on the body. 2011KiporPower 7
If a wire harness must contact the end of the bolts or screws or sharp edges and corners, protectthe contact part of the harness with a loom or by winding with electrical insulating tape. If the wireharness has a grommet, set the grommet securely. Take care not to pinch the wire harnesses during installation of a part. If a wire harness hasdamaged 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’soperating instructions carefully before operating the tester. Be sure that the tester battery is fullycharged and the meter is functioning properly2.5 Serial numberKiporPowerSystems,Inc.The generator serial number identifies your particular unit and is important when ordering parts andaccessories. It is also used by your dealer and distributor for warranty administration. 2011The generator serial number is stamped on the engine block to the right of the oil dipstick. It is also on alabel on both ends of the generator carton as well as the certificate of quality.8
