WARNING SIGNS

DANGER
respecting these directions the user may place at risk persons and objects.

CAUTION
By not respecting these directions the user can cause technical damage to the unit and/or to the installation.

SAFETY INSTRUCTIONS

• The engine has been built to the specifications of a machine manufacturer, and it is his responsibility to ensure that all necessary action is taken to meet the essential and legally prescribed health and safety requirements. Any use of the machine other than that described cannot be considered as complying with its intended purpose as specified by the factory, which therefore declines all responsibility for accidents caused by such operations.
• The following instructions are intended for the user of the machine in order to reduce or eliminate risks, especially those concerning the operation and standard maintenance of the engine.
• The user should read these instructions carefully and get to know the operations described. By not doing so he may place at risk his own health and safety and that of anyone else in the vicinity of the machine.
• The engine may be used or mounted on a machine only by personnel suitably trained in its operation and aware of the dangers involved. This is particularly true for standard and, above all, special maintenance work. For special maintenance contact personnel trained specifically by the factory. This work should be carried out in accordance with existing literature.
• The factory declines all responsibility for accidents or for failure to comply with the requirements of law if changes are made to the engine’s functional parameters or to the fuel flow rate adjustments and speed of rotation, if seals are removed, or if parts not described in the operating and maintenance manual are removed and reassembled by unauthorized personnel.
• In addition to all other machine specifications, ensure that the engine is in a near horizontal position when starting. If starting manually, ensure that the necessary operations can be performed without any risk of striking against walls or dangerous objects. Rope starting (except for recoil rope starting) is not permitted even in emergencies.
• Check that the machine is stable so that there is no risk of overturning.
• Get to know the engine speed adjustment and machine stop operations.
• Do not start the machine in closed or poorly ventilated environments. The internal combustion process generates carbon monoxide, an odourless and highly toxic gas, so spending too long a time in an environment where the engine discharges its exhaust products freely can lead to loss of consciousness and even death.
• The engine may not be used in environments containing flammable materials, explosive atmospheres or easily combustible powders, unless adequate and specific precautions have (machines). been taken and are clearly stated and certified for the machine.
• To prevent the risk of fire, keep the machine at a distance of at least one metre from buildings or other .
• Children and animals must be kept at a sufficient distance from the machine to prevent any danger resulting from its operation.
• Fuel is flammable, so the tank must be filled only when the engine is turned off. Dry carefully any fuel that may have spilled, remove the fuel container and any clothes soaked in fuel or oil, check that any sound-absorbing panels made of porous material are not soaked with fuel or oil, and make sure that the ground on which the machine is located has not absorbed fuel or oil.
• To start the engine following the specific instructions provided in the engine and/ or machine operating manual. Do not use auxiliary starting devices not originally installed on the machine (e.g.Start pilot systems which utilise ether etc.)
• Before starting, remove any tools that have been used for carrying out maintenance work to the engine and/or the machine and check that any guards removed have been replaced. In cold climates it is possible to mix kerosene with the diesel fuel to make the engine easier to start. The liquids must be mixed in the tank by pouring in first the kerosene and then the diesel fuel. Consult the technical office for mixture proportions. Petrol may not be used because of the risk of it forming flammable vapours.
• During operation the surface of the engine reaches temperatures that may be dangerous. Avoid in particular all contact with the exhaust system. Before carrying out any work on the engine, turn it off and allow it to cool down. Do not perform any temperatures that may be dangerous. Avoid in particular all contact with the exhaust system.
• Before carrying out any work on the engine, turn it off and allow it to cool down. Do not perform any operation while the engine is running.
• The liquid cooling circuit is under pressure. Do not carry out any checks before the engine has cooled down, and even then open the radiator cap or the expansion tank cautiously. Wear protective clothing and glasses. If there is an electric fan, do not approach the engine while it is still hot as the fan may come on moving even when the engine is not running. Clean the cooling system with the engine turned off.
• While cleaning the oil bath air filter, check that the oil is disposed of in such a way as not to harm the environment. Any filtering sponges in the oil bath air filter should not be soaked with oil. The cyclone pre-filter cup must not be filled with oil.
• Since the oil must be emptied out while the engine is still hot (approx. 80°C), particular care should be taken in order to avoid burns. In any case make sure that oil does not come into contact with your skin because of the health hazards involved.
• Check that the discharged oil, the oil filter and the oil contained in the oil filter are disposed of in such a way as not to harm the environment.
• Close the fuel tank filler cap carefully after each filling operation. Do not fill the tank right up to the top, but leave sufficient space to allow for any expansion of the fuel.
• Fuel vapours are highly toxic, so fill up only in the open air or in well ventilated environments.
• Do not smoke or use naked flames while filling.
• Take care when removing the oil filter as it may be hot.
• The operations of checking, filling up and replacing the cooling liquid must be carried out with the engine turned off and cold. Take particular care if liquids containing nitrites are mixed with others not containing these compounds as this may give rise to the formation of nitrosamines which is a health hazard. The cooling liquid is polluting, so dispose of in a environment-friendly manner.
• During operations which involve access to moving parts of the engine and/ or removal of the rotary guards, disconnect and insulate the positive cable of the battery so as to prevent accidental short circuits and activation of the starter motor.
• Check the belt tension only when the engine is turned off.
• In order to move the engine use exclusively the eyebolts fitted for this purpose by the factory. These lifting points are however not suitable for the entire machine, so in this case use the eyebolts fitted by the manufacturer.
• When a peripheral device uses a flywheel generator power,do not disconnect the battery connections from the engine, or it may give the peripheral damage.

OVERALL DIMENSIONS

BEFORE STARTING

Carefully read and follow all instructions in this booklet as well as all those with the equipment on which this engine is used. Failure to do so will make warranty void.

USE

The engine may be damaged if operated with insufficient lube oil. It is also to supply too much lube oil to the engine because a sudden increase in engine rpm could be caused by its combustion. Use proper lube oil preserve your engine. Nothing affects the performance and durability of your engine more than the
lube oil you use. If inferior oil is used, or if your engine oil is not changed regularly, the risk of piston seizure, piston ring sticking, and accelerated wear out the cylinder liner, bearing and other moving components increases significantly.
Always use oil with the right viscosity for the ambient temperature in which your
engine is being operated. Use the chart on this page when choosing your engine oil.
The used engine oil can cause skin-cancer if kept frequently in contact for prolonged period. If contact with oil cannot be avoided, wash carefully your hands with water and soap as soon as possible.
Do not disperse the oil in the ambient, as it has a high pollution power.
