• Forced air convection cooling system

• Composite steel fan cover for minimum noise levels

Our four stroke diesel engines are air cooled with a direct fuel injected intake system. They offer maximum efficiency through the minimal conservation of energy and materials. These diesel engines are compact and lightweight. They are easily maintained and portable making it convenient to move. They are widely used as a source of mechanical power for industrial, agricultural, and machinery equipment. Some applications include irrig ation equipment, diesel powered pressure sprayers, grass-cutting machines, and soil-sampling machines. Other applications include vibration rammers, shock rammers, marine engines, lightweight transport vehicles, portable compressors, and lightweight portable generators.

This operating manual will explain how to operate and maintain your series of engines. Please read it before running the engine for correct operation.

To ensure long engine life please follow the operating requirements listed in this manual.

If you have any questions or suggestions about this manual, please contact your local dealer or us. Consumers should notice that this manual might differ slightly from the actual product as

more improvements are made to our products. Some of the pictures in this manual may differ slightly from the actual product as well. Eastern Tools and Equipment, Inc. reserves the right to make changes at any time without notice and without incurring any obligation.

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.

• Exercise extreme care when operating the

engine near people or animals. Keep the exhaust pipe free of external objects.

REFUELING PRECAUTIONS

• Be sure to stop the engine before refueling.

• Do not overfill the fuel tank.

• If fuel is spilled, wipe it away carefully and

wait until the fuel has dried before starting the engine again.

• When changing oil, make sure that the fuel

cap is tightly secured to prevent fuel leakage.

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.

• Keep the engine away from flammables

and other hazardous materials.

PROTECTIVE COVER

• Always place the protective covers

over the rotating parts. If rotating parts such as the driving pulley, belts, and shafts are exposed, serious injuries can be caused. To prevent injury, please equip all rotating parts with protective covers.

• Be careful of hot parts. The muffler

and other engine parts can become very hot while the engine is running or after the engine has been run. Always operate the engine in a safe area and keep children away from running engines.

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.

• Be careful of fuel spillage when

transporting the engine. Always tighten the fuel cap and close the fuel strainer cock before moving the engine around.

• Never move the engine while it is in

operation.

• If the engine will be transported over a

long distance, drain all the fuel from the fuel tank to prevent fuel leakage.

PRE-OPERATION CHECKS

• Carefully check fuel pipes and fuel joints

for fuel leakage. Leaked fuel creates a dangerous situation.

• Verify that all the nuts and bolts of the

engine are tights. A loose nut or bolts may cause serious engine failure and could lead to serious injuries.

• Always check the engine oil and refill it if

necessary.

• Always check the fuel level and refill it if

necessary. Never overfill the fuel tank

• Avoid wearing dangling or long clothes

such as loose aprons, towels, and waist belts, as these items may be caught in a rotating part of the engine.

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 travele d by the driver wheel. If this is not properly calculated and matched, the desired speed on the driven wheel will be incorrect. A formula used to calculate the necessary diameters of the various wheels is provided below.

The diameter of driving wheel (belt wheel) can be calculates as follows:

Diameter of engine driving wheel (engine pulley) =

Diameter of driven machine x speed of driven machine

Diesel speed (engine speed)

(5) Make sure that the belt has a correct tension to it.

Note: If the belt is to tight, the engine bearings will wear at a high rate leading to engine failure. If the belt is to loose, the belt will slip at high speeds and high loads causing high pitch whistling noises.

1-2.1 Allowed clearance between belt wheel and engine

The belt pulley wheel should be as close to the engine as possible. The values of L are tabulated in table 1-1.

Table 1-1. Allowed belt pulley wheel to engine distances.

1-2.2 Crankshaft driving angles must be less than 120o, see Fig 1-1

The tilt must be kept within the allowed values shown in Fig 1-2

Fig 1-1. Allowed driving angles. 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.

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. Keep flammable and combustible goods away from engine while engine is running. The

engine should be placed in a simple ventilated place.

3. Do not touch the muffler when the engine is running or just after it has stopped.

4. The diesel engine should be operated at its rated power and rated speed. If abnormal

operating conditions are detected, stop the engine immediately to check and fix the problem.

5. A new engine must be properly broken in. For the first 20 hours, run the engine at low

speed and low loads. Do not allow engine to run at high speeds and high loads during the break in period.

2-2 Fuel Choices

Oiling plug: In winter, if it is difficult to start the engine, pull the plug out and fill 2cc of lube oil into the hole and then put the plug back in place. Make sure the plug is tight, if not, the engine can absorb dust into the combustion chamber and damage itself.

Muffler

The factory has replaced the engine fuel and engine oil once already. To check the fuel pipeline, make sure the fuel line is completely drained. IF there is air in the pipeline, drain it out. To do this, loosen the nut between the injection pump and fuel pipe, then drain out the air until there are no bubbles left in fuel line.

Compression release lever: Push the lever down to start the engine

Oil Lubricant Inlet: Place the engine on level ground and fill the lubricant into the inlet. When checking the oil level, gently place the dipstick into the oil. Do not turn the oil scale.
