1.2 - MAINTENANCE REGULATIONS
- Use genuine DERBI spare parts and lubricants recommended by DERBI. Non-genuine or unauthorised parts
may damage the machine.
- Only use the specific tools intended for this machine.
- During re-assembly, always use new oil seals, gaskets, piston rings and grommets.
- After dismantling, clean the components with solvents that are non-inflammable or that have a high flam-
mability point. Grease 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 re-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 machine.
- In the case of work on the machine’s electrical circuitry, check that electrical connections have been correc-
tly fitted, especially the earth connections.
Use only genuine DERBI spare parts. For all lubrication tasks use
oils and greases recommended by DERBI. Other makes make
seem similar in their function and appearance, but are inferior
in quality.
Examine all the locking rings carefully before fitting. Always re-
place the gudgeon pin circlips after every use. Replace distorted
locking rings. On fitting a locking ring (1), ensure that the sharp
edge (2) is on the opposite side to the force (3) to be applied to
it.
See the figure on the side, (4) Axle.
