NOTE:
1. If the speed handle is in the "Stop position and the engine is still running, turn the fuel
switch to the "OFF" position or loosen the high pressure oil pipe nut. The engine could be stopped
more than oneway other than the speed handle way.
2. If you cannot stop the engine with a load on it, then remove the load first than stop the engine.
5. If equipped with an electric starter, turn the key to the "Off' position.
6. Put the fuel handle to the "S" position.
7. Finally, pull slowly on the recoil handle until you feel resistance (this is when the piston is on the
compression stroke, where the intake and exhaust valves are closed). What this does is prevent the
engine from rustiong when not in use.
3. MAINTENANCE
3-1 Maintenance schedules
Keeping your generator well maintained will prolong the life of your generator. Everything needs to
be checked including the diesel engine, welder, generator, control cabinet, and frame. For overhau-
ling procedures, please refer to the instruction manual of the relative subassembly. If you need
these manuals, plsaes call our company and we will send you one. Before starting the maintenance,
make sure the diesel engine is off.
Please refer to the Table 3-1 for the proper maintenance schedule.
Table 3-1. Ma intenance schedule fo r dies el generator set
Note: "• "mark indicates that it needs special wrench, please contact with dealer.
3-1.1 Changing the engine oil (every 100 hours)
Take the oil cover out. Take off the oil drain plug when the diese! engine is still hot.
Be careful of hot oil and hot engine as you may get burned. The bolt is located at the bottom of the
cylinder. After draining the oil, put the bolt back and tighten it. Then fill with the proper engine oil to
the proper level.
3-1.2 Replacing the oil filter
1. Replacing the oil filter every 6 months or 500 hours of operation.
3-1.3 Air filter maintenance schedule
1. Clean air-filter every 6 months or 500 hours of operation.
2. If necessary, exchange it.
3. Do not use detergent to clean air filter element.
NOTE:
start the engine without the air filter. This can cause serious damage to the engine if foreign
objects enter the intake system. Always change the air filter on time.
3-1.4 Fuel filter maintenance
1. The fuel fil ter should be cleaned often to keep the engine running at maximum performance.
2.The recommended time period for cleaning the fuel filter is 6 months or 500 hours of operation.
a. To do this, first drain the fule from the fuel tank.
b. Loosen the small screws on the fuel switch and remove the fuel filter form the port. U se diesel
fuel to clean the fuel filter. Also, remove the fuel injector and clean the carbon deposit around it. The
recommended time period for this is 3 months or 100 hours.
3-1.5 Cylinder head bolt tensions
The cylinder head bolts should be tightened to specifications please refer to the diesel engine
manual for specifications and the special tools reuired to do this.
3-1.6 Battery check
Make sure the electrolytic solution of the battery is full. The engine uses a 12V battery. Due to nume-
rous starting cycles, the electrolyic solution may be u
ed up. Also,
before filling, verify that the battery is not damaged in any way. Add distilled water to the battery
when filling. Perform checks on the battery once a month.
3-2 Storing for long periods of time
If your generator needs to be stored for long periods of time, the following preparations
should be made.
1. Start the diesel engine for 3 minutes then stop it.
2. When the engine is still hot, change the engine oil with new engine oil of the proper
grade.
3. Pull the tubber plug out of the cylinder head cover and put 2CC of lubricating oil in it,
ten cover the plughole up again.
4. For manual starting generators, press the decompression handle down and pull the
recoil handle 2 or 3 times. This pushes the intake out. (Do not start the engine).
5. For electric started generator, press the decompression handle down and crank the
engine for 2-3 seconds. To do this, put the starter switch in the "Start" position. (Do not start the
diesel engine).
6. Finally, pull the recoil starter until you feel resistance; this is when the piston is on the compres-
sion stroke where the intake and exhaust valves are closed.Having the intake and exhaust valves
closed will prevent rust, as moisture cannot get inside the combustion chamber.
7. Clean the engine and store it in a dry place.
