REGULATIONS

This section describes the machine’s general safety and maintenance work rules.

SAFETY REGULATIONS

- In the event of having to carry out work on the engine while this is running, ensure that the area is well

ventilated, where possible using extractor fans. Never leave engines running in closed spaces. Exhaust gases

are poisonous.

Petrol is extremely inflammable and in certain conditions may explode. Smoking must not be allowed in the

work area, nor should there be naked flames or sparks.

MAINTENANCE REGULATIONS

- Use genuine DERBI spare parts and lubricants recommended by the manufacturer. Non-genuine or unau-

thorised parts may damage the engine.

Always use new gaskets and oil seals during re-assembly.

After dismantling, clean the components with solvents that are non-inflammable or with a high flammability

point. Lubricate all working surfaces before assembling, excluding tapered joints.

After assembly, check that all components have been correctly fitted and that they are functioning perfectly.

For dismantling, checking and assembly operations, use only tools with metric measurements. Metric screws,

nuts and bolts are not interchangeable with imperial measurement joining devices. Using unsuitable tools

and joining devices may damage the engine.

- In the case of work on the engine involving the electrical circuitry, check that electrical connections have

been correctly fitted.
