Discharge outlet and crushing screen cleaning
Remove the lid for discharge outlet maintenance: screw out the
through-bolt and remove it along with the case (pic. 24).
Loosen the top and external wing nuts and unhook the lid.
Tip the crushing screen down by screwing out the wing nuts (pic.
25) and clean the discharge outlet.
Always use safety gloves! The hammer mechanism knives
are very sharp! Use eventually a rod or other tool that cannot
damage the knives.
Maintenance of knives
To turn the cutting knives, you must first remove the socket plug
(engine is cooled down).
Disassemble the lid for discharge outlet maintenance as
described in the above article (pic. 24/25/26).
Then, after screwing out the check nuts, remove the lid of outlet
for crushing knives maintenance (pic. 1 note 9). Now you can see
into the knife disc. Now you must place the crushing knives in
front of the maintenance outlet. To do so, remove the crushing
screen so that the knife disc could turn on the outer side of the
hammer mechanism.
Remove the cotter key on the crushing screen axis (pic. 26) –
arrow.
Pull out the axis with the case (pic. 27 – arrow) and remove the
crushing screen.
Now CAREFULLY turn the hammer mechanism (use safety
gloves)
Pic. 21a shows the position at which knives can be disassembled.
ATTENTION: The knives are extremely sharp!
Loosen the holding screws and turn the knives by 180°.
Make sure the knives are fitted well again.
If the knives are blunt, you can have them sharpened at a
specialist or replaced with new ones.
Cleaning in general
Lubricate all movable parts with oil and safely re-fix all removed
parts after each cleaning.
Clean the engine with a rag. Avoid sprinkling with heavy water
current as water can get to ignition, fuel system and lubricant
system and cause failures.
Air filter and fuel screen cleaning
The air filter must be cleaned every 20-30 running hours. Remove
the air filter cover by screwing out the wing nuts (pic. 17a - arrow)
and pull out the air filter insertion.
Clean the filter with benzoline. Drop a few drops of motor petrol
on the filter after cleaning. Assembly in the opposite order.
Clean the fuel screen by removing the tank cover and pulling out
the screen (pic. 18a). The screen can carefully be blown-dry.
Transport and storing
The appliance can only be transported when the engine is off.
Clean the appliance thoroughly before storing.
Store the appliance at a clean and dry place with no fuel in the tank.
Storing
If the crusher is not used for a longer period of time, the following
works need to be executed:
Thorough cleaning and repair of the damaged varnish.
Sprinkle the movable and stressed parts with anti-corrosive oil.
Crusher shutdown and storing
Do not store the crusher in wet rooms, in rooms with fertilisers, in
stables and adjacent spaces.
At tipping, the motor oil can get to the combustion space and thus
cause problems at starting or oil carbonisation.
Risk of strong corrosion creation.
