Operation Manual

Use genuine DERBI spare parts and lubricants recommen-

ded by the Manufacturer. Non-genuine or unauthorised par-

ts may damage the machine.

Only use the specific tools intended for this machine.

During re-assembly, always use new seals, gaskets, piston

rings and grommets.

After dismantling, clean the components with solvents that

are non-inflammable or that have a high flammability point.

Grease all working surfaces before assembling, excluding

tapered joints.

After assembly, check that all components have been correc-

tly fitted and that they are functioning perfectly.

For dismantling, checking and re-assembly operations, use

only tools with metric measurements. Metric screws, nuts

and bolts are not interchangeable with imperial measure-

ment joining devices. Using unsuitable tools and joining de-

vices may damage the machine.

In the case of work on the machine’s electrical circuitry,

check that electrical connections have been correctly fitted,

especially the earth connections.
