Maintenance And Care; Maintenance; Tensioning The V-Belt; Replacing The V-Belt - ATIKA GHB 760 A Notice Originale

Feed branches with larger diameter slowly.
Do not allow the shredded material to pile up too high in the area
of the ejection opening. This can lead to shredded material
blocking the ejection channel, and backing up to the filler
opening.
Clean out the filler opening and ejection channel thoroughly if the
machine becomes blocked. Before doing this, stop the engine
and disconnect the spark plug connector.
Please do not exceed the maximum branch diameter specified
(cutting fresh wood) for your appliance (∅ see "Technical data").
Depending on the wood's nature and freshness the maximum
branch diameter the machine can process may be smaller.
The blades largely pull the material into the machine by
themselves.
Immediately stop the engine when the cutting unit is blocked to
prevent the engine overloading. Eliminate the fault before
restarting the engine.

reduces the engine's speed.
The V-belt tension is correct if it can be pressed down by approx.
10mm.
1. To check the V-belt (14) tension you have to remove the
belt cover (16).
2. Check the V-belt tension.
