HEALTH & SAFETY WARNING: THE FOLLOWING HEALTH AND SAFETY RECOMMENDATIONS SHOULD BE CAREFULLY OBSERVED. Carrying out certain operations and handling some substances can be dangerous or harmful to the operator if the correct safety precautions are not observed. Some such precautions are recommended at the appropriate points in this book.
provided in this Manual must first establish that neither personal safety nor equipment integrity are compromised by the choice of methods, tools or parts. Notes, Cautions, and Warnings As you read through the procedures, you will come across NOTES, CAUTIONS, and WARNINGS. Each one is there for a specific purpose.
We consider it to be in your interests to enlist the aid of an authorized Ford Power Products Distributor not only when repairs are required but also for regular maintenance. Distributors are listed at the back of this handbook.
EDI Engine Identification Decal An identification Decal is affixed to the valve cover of the engine. The decal contains the engine serial number which identifies this unit from all others. Use all numbers when seeking information or ordering replacement parts for this engine.
Owner’s Warranty Responsibilities As the off-road LSI engine owner, you are responsible for the performance of the required maintenance listed in your owner’s manual. Engine Distributors, Inc. recommends that you retain all records covering maintenance on your off-road engine, but Engine Distributors, Inc. cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

SERVICE LITERATURE A service manual can be purchased from your EDI distributor. This publication will provide the necessary servicing and overhaul information for your Ford Power Products engine. • WSG1068 SERVICE MANUAL - EDI • WSG1068 PARTS LIST - EDI BEFORE OPERATING THE ENGINE 1.
1. Auxiliary Circuits - When moved to this position the auxiliary electrical equipment such as radios and heater fans, can be operated without also connecting the starting circuit with the battery. 2. Off - When set to this position, the switch disconnects the auxiliary electrical equipment and the starting circuit from the battery.
INSTRUMENTS Your Ford Powered Equipment will have been fitted with instruments selected by the manufacturer. The types of instruments most likely to be encountered are detailed here. A typical instrument panel is shown below. Ammeter (Where Fitted) This instrument registers the charging current which is being passed to the battery from the alternator.
Charge Indicator Light (Where Fitted) If an alternator is fitted to your engine, a charge indicator light will also be fitted. The light will glow when the isolating switch is in the RUN position with the engine stationary and will therefore serve as a reminder either to turn the isolating switch to the OFF position or to start the engine.
STARTING THE ENGINE WARNING: ALL INTERNAL COMBUSTION ENGINES GIVE OFF VARIOUS FUMES AND GASES WHILE RUNNING. DO NOT START OR RUN THE ENGINE IN A CLOSED OR POORLY VENTILATED BUILDING WHERE THE EXHAUST GASES CAN ACCUMULATE. AVOID BREATHING THESE GASES AS THEY MAY CONTAIN POISONOUS CARBON MONOXIDE WHICH CAN ENDANGER YOUR HEALTH OR LIFE IF INHALED STEADILY FOR EVEN A FEW MINUTES.
STOPPING THE ENGINE Normal Conditions Following normal operating conditions, lower the engine speed to idle, disengage the clutch, and then turn the ignition switch to the OFF position. If the engine has been running under high power, let it run at fast idle speed a few minutes to cool the engine down. Abnormal Conditions Under abnormally overheated conditions, the engine may continue to run after the ignition switch is turned off.
FUEL RECOMMENDATION This engine is designed to operate on dry fuel such as LPG Grade HD5 or NG (1050 BTU/ft^ CAUTION: Use of fuels rated lower than the grades specified above may cause persistent, heavy spark knock, which can lead to engine damage. If your engine knocks heavily, or if you hear continuous spark knock while maintaining constant operating speeds, consult your distributor or another qualified technician.

RECOMMENDED MAINTENANCE *It is recommended that this operation is carried out by an authorized Ford Distributor. Depending upon the quality of the fuel used, it may be necessary to renew the filter element more frequently. ** PCV Valve inspection and Spark Plug replacement are recommended at the interval(s) described.
Petroleum Institute Certification Mark on the front of the container, or API specification SH, or SJ. NOTE: Ford Power Products industrial engines are designed to perform with engine oils that are licensed by the American Petroleum Institute (API), and oils carrying the most current API classification should be used.
Used Engine Oils WARNING: PROLONGED AND REPEATED CONTACT MAY CAUSE SERIOUS SKIN DISORDERS INCLUDING DERMATITIS AND SKIN CANCER. WARNING: AVOID EXCESSIVE CONTACT—WASH THOROUGHLY AFTER CONTACT. KEEP OUT OF THE REACH OF CHILDREN. WARNING: PROTECT THE ENVIRONMENT: IT IS ILLEGAL TO POLLUTE DRAINS, WATER COURSES OR SOIL.
This filter is especially designed for use in engines built by Ford to give successful operation with the recommended oil filter change intervals. Contact your nearest EDI Distributor/Dealer listed in the back section to obtain the correct filter.
Ignition System The 6.8L engine is equipped with a coil-on-plug ignition system. Rather than a remotely mounted coil with secondary ignition wires, this system has a separate ignition coil mounted on each spark plug. Operation of the coils is controlled by the engine computer module (GCP), which computes ignition timing based on inputs from engine sensors.

4. Check the gaps of the new spark plugs with a feeler gauge, and, where necessary, bend the outer ground extension to achieve the specified gap. 5. Use a proper spark plug spanner to avoid damaging the insulators, screw the new spark plugs into the cylinder head and tighten them to the specified torque value listed under specification of this manual.
The belts should be visually inspected for signs of wear or damage. It should be renewed if necessary. Refer to Service Manual. NOTE: May be purchased from your local Ford Power Product Distributor listed on the back of this handbook.
Renew Air Cleaner Element Your air cleaner filters air entering the engine induction system and acts as a silencer and a flame arrester. Air that contains dirt and grit produces an abrasive fuel mixture, and can cause severe damage to the cylinder walls and piston rings. Damage to the cylinder walls and piston rings will cause high oil consumption and short engine life.
Only this antifreeze, or proprietary antifreeze meeting Ford specification WSSM97B44- D or Ford specification ESE-M97B44-A should be used when topping-up or re-filling the cooling system. Motorcraft Super Plus 2000 coolant has long life characteristics and if the concentration is kept to a...

NOTE: If a major component of the cooling system is renewed such as the radiator, water pump etc., the system should be flushed and re-filled with a 50% solution of Motorcraft Super Plus 2000 coolant and clean water. In territories where the ambient temperature is such that no protection against freezing is required, it is recommended that a 25% concentration of Motorcraft Super Plus 2000 coolant is used.
Draining, Flushing and Filling the Cooling System WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP WHILE THE ENGINE IS OPERATING OR WHEN THE COOLING SYSTEM IS HOT. MAY CAUSE PERSONAL INJURY OR DAMAGE TO COOLING SYSTEM OR ENGINE. TO REDUCE THE RISK OF HAVING SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE DEGAS BOTTLE WHEN REMOVING THE PRESSURE RELIEF...

Storage Storage - One Month • While the engine is running, treat upper cylinders by spraying engine fogging agent (from your local aftermarket supplier) into the air intake for about two minutes. Open throttle for short burst of speed, shut off engine and allow it to come to a stop while continuing to spray into air intake.
ENGINE SYSTEM CHECK GCP System Check NOTE: Most items listed in the possible cause column may not set a diagnostic fault indicator or illuminate the MIL light. NOTE: EDI engines are used in many different applications and equipment. When performing any system diagnosis be aware of any OEM inputs or equipment monitoring devices that may have an effect on the engine’s performance or any of the engine’s operating systems.
