General remarks and safety information
−
KOHLER Engines are built to supply their performances in a safe and long-lasting way.
To obtain these results, it is essential for users to comply with the servicing instructions given in the relative manual along with
the safety recommendations listed below.
− The engine has been made according to a machine manufacturer's specifications and all actions required to meet the essential
safety and health safeguarding requisites have been taken, as prescribed by the current laws in merit.
All uses of the engine beyond those specifically established cannot therefore be considered as conforming to the use defined
by KOHLER which thus declines all liability for any accidents deriving from such operations.
−
The following indications are dedicated to the user of the machine in order to reduce or eliminate risks concerning engine ope-
ration in particular, along with the relative routine maintenance work.
−
The user must read these instructions carefully and become familiar with the operations described.
Failure to do this could lead to serious danger for his personal safety and health and that of any persons who may be in the
vicinity of the machine.
•
The engine may only be used or assembled on a machine by technicians who are adequately trained about its operation and
the deriving dangers.
This condition is also essential when it comes to routine and, above all, extraordinary maintenance operations which, in the
latter case, must only be carried out by persons specifically trained by
KOHLER and who work in compliance with the existing
documentation.
− Variations to the functional parameters of the engine, adjustments to the fuel flow rate and rotation speed, removal of seals,
demounting and refitting of parts not described in the operation and maintenance manual by unauthorized personnel shall relieve
KOHLER from all and every liability for deriving accidents or for failure to comply with the laws in merit.
− On starting, make sure that the engine is as horizontal as possible, unless the machine specifications differ.
In the case of manual start-ups, make sure that the relative actions can take place without the risk of hitting walls or dangerous
objects, also considering the movements made by the operator.
Pull-starting with a free cord (thus excluding self-winding starting only), is not permitted even in an emergency.
−
Make sure that the machine is stable to prevent the risk of overturning.
−
Become familiar with how to adjust the rotation speed and stop the engine.
− Never start the engine in a closed place or where there is insufficient ventilation.
GENERAL SAFETY DURING OPERATING PHASES
– The procedures contained in this manual have been tested and selected by the manufacturer’s technical experts, and hence
are to be recognised as authorised operating methods.
– A number of procedures must be carried out with the aid of equipment and tools that simplify and improve the timing of
operations.
– All tools must be in good working condition so that engine components are not damaged and that operations are carried out
properly and safely.
It is important to wear the personal safety devices prescribed by work safety laws and also by the standards of this manual.
– Holes must be lined up methodically and with the aid of suitable equipment. Do not use your fingers to carry out this
operation to avoid the risk of amputation.
– Some phases may require the assistance of more than one operator. If so, it is important to inform and train them regarding
the type of activity they will be performing in order to prevent risks to the health and safety of all persons involved.
– Do not use flammable liquids (petrol, diesel, etc.) to degrease or wash components. Use special products.
– Use the oils and greases recommended by the manufacturer.
Do not mix different brands or combine oils with different characteristics.
– Discontinue use of the engine if any irregularities arise, particularly in the case of unusual vibrations.
– Do not tamper with any devices to alter the level of performance guaranteed by the manufacturer.
SAFETY AND ENVIRONMENTAL IMPACT
Every organisation has a duty to implement procedures to
identify, assess and monitor the influence of its own activities
(products, services, etc.) on the environment.
Procedures for identifying the extent of the impact on the envi-
ronment must consider the following factors:
- Liquid waste
- Waste management
- Soil contamination
- Atmospheric emissions
- Use of raw materials and natural resources
- Regulations and directives regarding environmental impact
In order to minimise the impact on the environment, the manu-
facturer now provides a number of indications to be followed
by all persons handling the engine, for any reason, during its
expected lifetime.
- All packaging components must be disposed off in accor-
dance with the laws of the country in which disposal is ta-
king place.
- Keep the fuel and engine control systems and the exhaust
pipes in efficient working order to limit environmental and
noise pollution.
- When discontinuing use of the engine, select all compo-
nents according to their chemical characteristics and dispo-
se of them separately.
