Method for starting and stopping an internal combustion engine of an industrial truck

A method of starting and stopping an internal combustion engine of an industrial truck, said truck having an electric starter and an auxiliary hydraulic starter, the method of starting the internal combustion engine comprising the steps of:

• testing safety conditions, of detecting operator instructions or requests;
• and
• testing conditions for auxiliary hydraulic starting,
• wherein the auxiliary hydraulic starter is driven by discharge from a hydropneumatic accumulator, wherein the step of testing conditions for auxiliary hydraulic starting for the internal combustion engine includes testing the pressure of the hydropneumatic accumulator,
• wherein the step of testing conditions for auxiliary hydraulic starting for the internal combustion engine also includes testing that a time interval has elapsed since the last stop of the internal combustion engine,
• wherein the method includes starting the internal combustion engine as a function of the result of said testing steps and as a function of said detected operator instructions or request.
