How to determine wear caused by elongation
- Check the type of chain installed; this is indicated on the
external plates of the chain (if illegible contact a DIECI
service centre).
- Identify the chain pitch using the table (g.84/D).
(E.g. AL8/BL8 Fleyer Chain; Pitch: 1”/25.40 mm) and
multiply by per 10.
- Measure 10 pitches of the chain to check (g.67/D).
- If the measurement is 2% longer than the pitch indicated
in the table multiplied by ten, the chain is worn and must
be replaced.
2% of the measurement = [Measurement: 100] x 2
- CAUTION:
The measurement must be made in more than one point
(because the degree of wear may not be the same eve-
rywhere) and while the chain is tensioned. Measurement
can be carried out with a gauge or ruler featuring a scale in
millimetres (g.86/D).
Inspection, cleaning and lubrication
- Place the machine on a at and level surface.
- Position the machine on the stabilisers.
- Completely extract the boom so it is horizontal.
- Switch off the engine and remove the ignition key.
Place a “maintenance work in progress” sign in the cab.
- Clean the chains with a clean cloth that does not leave
residues to remove surface dirt.
- Thoroughly brush the chains to remove all dirt using a
hard nylon brush and clean diesel fuel. Then blow with
compressed air.
- Carefully inspect the chains as described in the “check
for wear” paragraph.
- Lightly lubricate the chains using a brush soaked in oil
(see the “lubrication” paragraph).
- Remove any excess oil from the entire surface of the
chains with a clean cloth.
- Activate the boom several times to distribute the lubri-
cant evenly.
- CAUTION:
If the chains need to be replaced, contact a DIECI service centre.
- CAUTION -
The chains can be weakened by hydrogen.
IT IS STRICTLY FORBIDDEN to work in acid areas.
Work in oxidising and corrosive environments for the
shortest possible time.
