• Take the following steps to verify ignition quality:
1. Put the spark plug cap back on.
2. Grab the rubber of the spark plug cap and press the outermost electrode against the mass
of the engine.
3. Pull the starter cord.
4. Check for sparks between the electrodes.
5. The spark plug is in good condition if the sparks are clear and neatly centred between the
electrodes.
6. Weak, irregular and not well-centred sparks indicate that the spark plug must be replaced.
Caution:
Fitting or changing a spark plug must be done with utmost caution so as not to
damage the screw thread in the engine. Secure the sparkplug with a torque of
20Nm.
11.5.3 Changing the air filter
• This procedure is exactly the same as for cleaning the air filter (see § 11.4.3, Cleaning the air
filter).
• New, suitable air filters are available from your ELIET dealer or an authorised service centre of
the relevant engine brand.
11.5.4 General lubrication treatment
ELIET is committed to using high-quality materials that extend a machine’s life cycle despite the
sometimes extreme work circumstances in which chippers are being used. For this reason, special
lubrication products have already been applied in the factory. ELIET also recommends lubricating
all the parts below on a regular basis:
• Bearings
• Hinges
A. Lubricating bearings
Caution:
As applies to all maintenance work, the engine must be turned off. Detach the
spark plug cap or lead. Wearing gloves is essential here: the blades are razor-
sharp and can cause deep cuts.
