correct working conditions

Working on a hillside
Whenever possible work “uphill” following the incline. If it is not possible to avoid working on the sides of the hill,
drive from the top to the bottom in order to reduce the “terrace” effect..
Practical remarks:
The worked area should always be at the right-hand side of the driver. The best way is to work on alternate strips..
PROBLEMS AND THEIR CAUSES
Problem
Cause
Solution
Excessive vibrations
1 Blades or hammers broken or too worn
out
Replace the worn-out or broken
parts
2 Blades or hammers stuck on their pins
Clean and grease the pins
3 Insufficient balancing of the rotor
Have the rotor checked for
balance by a specialist
4 Rotor bearings worn out
Take down and replace the
bearings
Insufficiently even cut because of
a decrease of the rotor speed
1 Insufficient tension of the belts
Adjust the tension
2 Belts too worn out
Replace the belts
Belts overheat
1 Wrong tension of the belts
Check the tension
2 Working position too low on the ground
Adjust working height
3 The axis of the transmission and the axis
of the rotor are not alligned
Adjust alignment of the pulleys
Bevel gear pair overheats
1 Lack of oil
Top up oil
2 Oil is exhausted
Change oil
The blades or hammers wear out
too quickly
1 Working position is too low
Increase the height of the rotor
from the ground
Oil leaks from the transmission
on the belt side
1 Oil seal is either broken or worn out
Replace oil seal
The supports of the rear roller or
the wheels are deformed
1 The supports of the roller or of the
wheels
have
undergone
excessive
lateral stress
Lift the machine off the ground
when driving in reverse gear
Side protection plates are bent
out of shape
1 The machine has been lowered on the
material to be shredded from a position
off the ground (transport position)
The machine must be in its
working position before it meets
the material to be shredded
Belts wear out too much
1 Wrong tension of the belts
Adjust the tension
2 The transmission pulleys are not alligned Adjust the alignment of the
pulleys
Transmission organs broken
1 The machine has been started or
