PREFACE Thank you for purchasing products from Eastern Tool & Equipment, INC. The following manual is only a guide to assist you and is not a complete or comprehensive manual of all aspects of maintaining and repairing your engine. The engine you have purchased is a complex piece of machinery.
SAFETY PRECAUTIONS Please be sure to follow each instruction carefully EXHAUST PRECAUTIONS • Never inhale the exhaust gases, it contains carbon monoxide, a colorless, odorless and extremely dangerous gas which can cause unconsciousness or death • Never operate the engine indoors or in a poorly ventilated area, such as a tunnel or cave, etc.
Page 5
FIRE PREVENTION • Never operate the engine while smoking or near an open flame. • Never use the engine around dry brush, twigs, cloth-rags, or other flammable materials. • Keep the engine at least 3 feet (1 meter) away from buildings or other structures.
Page 6
SURROUNDINGS • Operate the engine on a table or level surface free of small rocks and loose gravel. • Operate the engine on a level surface. If the engine is tilted, fuel may spill from the gas tank. NOTE: Operating the engine at a steep incline may cause the engine to seize up due to improper lubrication even when the oil level is a maximum.

1-2 Overall engine dimensions Installation Conditions (1) There must be a tight stationary foundation for the diesel engine to avoid vibrations or movement when the engine is running. For prolonged engine life, consider using some type of motor mount. (2) Make sure that the centering position of the output shaft is properly aligned.
(3) Verify that the dimensions of the hole on the belt wheel and keyway shaft match or correspond with each other. Also make sure that the bolt of the engine shaft is tightened to the proper torque specifications. (4) When the engine is matched with other belt driven machines, the total desired belt distance traveled by the driven wheel must equal the total distance traveled by the driver wheel.
Fig 1-2. Allowed tilt angles. 1-2.3 Please contact our dealers about the electric circuits involved with this engine. We recommend the use of accumulators rated at 20 hours shown in table 1-2. Table 1-2. Model Units: (amp-hours) 170F 18~24 178F 24~26 186F 36~45...
CHAPTER 2 DIESEL ENGINE OPERATION 2-1 Please pay close attention for safe operation of the diesel engine. 1. The fuel used must be filtered by silk fabric or settled for 24 hours before it is used in the engine. Never add oil to the crankcase when the engine is running. 2.

Oiling plug: In winter, if it is difficult to start the Compression release lever: engine, pull the plug out and fill 2cc of lube oil Push the lever down into the hole and then put the plug back in to start the engine place.

If your engine is still relatively new, follow the break in procedure. The life of the engine will shorten if it is overloaded during its break in period. For the first 20 hours, the engine must be started and stopped according to the test run method. Avoid overloading the engine Change the engine oil regularly.
2-3 Starting the Diesel Engine 2-3.1 Recoil Starting Note: When the engine is running, do not pull the recoil handle, otherwise the engine may be damaged.
2-3.2 Diesel engine with electric starter system (1) Starting The preparation of the diesel engine for the electric starting system is the same as the manual recoil type. a. Open the fuel cock. b. Set the speed governor lever to the start position. c.

Warning: Never use flammable liquids as fuel, such as gasoline etc. Also, never take away the air cleaner for easy starting of the engine, doing so may cause explosions from the intake gases. Never take the oil plug unless you’re planning on filling the oil. If the plug is not in place, rain, dust, and other impurities may be sucked into the engine causing serious damage to the engine parts.
2-4 Running and stopping of the Diesel Engine 2-4.1 Running the Diesel engine (1) Preheat the engine for three minutes at no load. (2) Set the speed governor lever to the desired speed. Use the speed governor lever to control the speed of the engine.

(4) If the engine comes with an electric starter, turn the starting switch to the “Off” position. (5) Pull the recoil handle slowly until pressure is felt by your hand, this means the piston is on the compression stroke; where the intake and exhaust valves are closed and then let the handle recoil back into the engine.
CHAPTER 3. TECHNICAL MAINTENANCE OF DIESEL ENGINE 3-1 Daily checks and maintenance Check the oil level of the engine to see whether it is between the upper and lower limits. Check to see whether there any oil leaks within the engine. Keep the engine clean by cleaning up the dirt and other greasy deposits on the engine.
The core of the air filter may become dirty from various impurities. If this occurs, the performance of the engine will decrease because the amount of air entering the combustion chamber is incorrect. Also, because the amount of air is incorrect, the amount of fuel entering also becomes incorrect leading to an overall incorrect air/fuel mixture.

(3) Take the rubber plug off the cover of the rocker shaft and put about 2cc of lubricant into it and put the plug back in place. The figure below shows where to access the plug. (4) For recoil starting engines, push the decompression lever down and pull the recoil starter two or three times.

Improper maintenance: The life of an engine or your equipment depends upon the conditions under which it operates, and the care it receives. Some applications, such as tillers, pumps, and rotary movers, are very often used in dusty or dirty conditions, which can cause what appears to be premature, wear.
