Caution:
Never tighten the chain too tightly. Too much driving capacity would
be required as a result, leading to extra wear of the chain and sprockets. Fur-
thermore, a high radial tension can harm the cap seals and bearings of the drive
box.
Caution:
When checking the chain tension, also check the chain and the sp-
rocket for wear and tear. If the teeth are worn the sprockets and chain must be
replaced. Contact your authorised ELIET dealer for assistance.
Caution:
Use this maintenance to lubricate the chain
(read § 11.5.7; page 48)
• Carefully replace the protective cover and fasten it.
11.5.9. Replacing the blades
The PPM
TM
(Permanently Sharp Blades) are self-sharpening; they don’t require sharpening.
However, during the dethatching, the blades wear down, making them shorter.
• If the blades are worn down by more than 20 mm, the
machine will be less efficient and the manufacturer
recommends replacing them. (remaining blade length
20 mm)
• To disassemble the blades, the machine needs to be placed on the supplied Easy Clean™
cleaning support.
• Then tilt the machine backwards
(1)
so that it is resting
on its handlebar. In this way, the blades can be reached
in complete safety.
• Each blade is individually mounted in the blade holder
with an M8 bolt.
• Unscrew each bolt (spanner size 13). And then pull each
blade out of its blade holder with a pair of pliers.
• Then blow compressed air into each empty blade space
so that no dirt is left in it.
• A new blade set can be order at any authorised dealer under number: BU 402 100 400.
• Place the new blades in the blade holders. Make sure
that the blade is pointing the right way
(2)
.
• Screw the bolts back into the holders. Make sure that
the bolt is always placed on the discharge side.
• Then re-tighten all bolts firmly (tightening torque 20
Nm). Mark each bolt that has been tightened so that
you do not forget a bolt.
