2. SERVICE INFORMATION 2.1 The importance of proper servicing Proper servicing is essential to the safety of the operator and the reliability of 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. 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.
2.3 Service rules • Use genuine KIPOR or KIPOR-recommended parts and lubricants or their equivalents. Parts that do 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 before reassembly. After reassembly, check all parts for proper installation and operation.
• If a wire harness must contact the end of the bolts or screws or 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.

3. Troubleshooting This troubleshooting section contains troubleshooting trees organized by common groups of symptoms. Some testing information is contained in these sections. The following chapters of this manual focus on individual components and sub assemblies which will give you the assembly and reassembly procedures along with detailed specifications and testing procedures. 3.
3.2 Hard starting No fuel Check the fuel level in the tank. Add fuel and restart the engine. Sufficient fuel Loosen the drain screw and check whether fuel reached the float chamber and the oil level. Abnormal Check the fuel lines for blockage. Normal Dry Remove the spark plug and check for wet or fouled electrode. Check for blockage in the carburetor intake port and nozzle. Clean the electrode and restart, Ensure the choke is not closed. If flooding is severe, check the carburetor float valve.
C. Ignition system ■ Fill in oil to the demanded level. ■ Use the genuine spark plug A7RTC. ■ Spark plug inspection 1. Disassemble spark plug 2. Install spark plug onto spark plug cap. 3. Set the oil switch to the “ON” position. Ground the negative (—) electrode (i.e. threaded part) of the spark plug against the shroud and pull the recoil starter rope to check the spark plug. Normally you should see the spark jump the electrode gap when the plug is firing.
3.2 Hard Starting Continued Measure the spark plug gap and perform the spark plug test. Gap: 024-028 in (0.6—0.7mm) No spark Perform the spark test again using a Good spark new spark plug Replace the spark plug No spark Remove the control panel. Perform Good spark spark test with a new ignition module.
3.3 Engine oil level is low, but engine does not stop. (Defective oil switch) Drain out oil completely, disconnect alarm No continuity connection wire, and check the continuity Replace the oil level alarm between alarm outlet terminal and ground. Continuity Reset the alarm connection wire, disconnect No continuity Repair or replace the wire ignition module and check the continuity harnesses between the plug orange wire and ground. Continuity Ignition module fault: replace module. 3.

2. Stop engine, disconnect oil alarm connector, check the connector conduction, no conduct is normal. 3. Drain out the oil inside engine and check the conduction, conduct is normal. 4.4 Air cleaner Inspection/Cleaning: 1) Loosen the cover screw and remove the maintenance cover. 2) Disengage the locking tab by pushing it, and remove the air cleaner cover. 3) Remove the element from the air cleaner case. 4) Clean the element in warm soapy water, rinse and allow to dry thoroughly and allow to dry.
Caution ■ A dirty air cleaner will restrict air flow to the carburetor, reducing engine performance. If the engine is operated in dusty areas, clean the air cleaner more often than specified in the Maintenance Schedule. ■ Never run the engine with no element or a damaged element. Engine damage will result. 4.5 Spark plug Inspection/Cleaning: 1) Remove the spark plug cap and remove the spark plug. 2) Remove carbon or other deposits with a plug cleaner or stiff ire brush.
4) Measure the plug gap with a wire-type feeler gauge. Adjust by bending the side electrode if the measure is not accord with the asked valve. Spark plug clearance .024-.028 in.

Torque valve is 8.-~9.6 ft lbs, 11~13 N.m 4.6 Valve clearance Caution ■ Valve clearance inspection and adjustment must be performed with the engine cold.
2) Remove the four tighten bolts and disassemble the cylinder cover. Don’t remove the cylinder cover with excessive force as it may deform. Replace the cylinder cover if it is deformed. 3) Remove the spark plug; screw the dial indicator in the spark plug hole. Rotate the rotor in a clockwise movement and set the piston at top dead center. Caution ■ Make sure both the intake and exhaust valves are closed.
4) Insert a feeler gauge between the rocker arm and the valve and measure the valve clearance.
