Maintenance Instructions - EMAK BT 5500 Manual De Instrucciones

MACHINE STRUCTURE
Th e machine is supplied fully assembled. Before starting the
machine, it is recommended to check the hammer assembly
GB
and integrated shredder disc for the presence of foreign matter
which may have accumulated during transport or storage, and
which can cause the machine to jam during start-up. Aft er
approximately the fi rst 1 hour of operation, fully tighten all of
the fi xing screws securing the hammer assembly and shredder
discs.
CAUTION - Check the engine oil frequently.
START-UP
WARNING - Before starting the machine, carefully read
the engine manufacturer's instruction manual.
Th e machine must be positioned on a fl at and stable surface to
prevent the risk of tipping.
If the machine becomes clogged, stop the engine by turning the
switch to "ST0P". To open the hopper, loosen the screws and
remove the cause of the blockage, then close the hopper. Restart
the engine.
OPERATING INSTRUCTIONS
Branches are crushed by a shredder blade and a counterblade.
Other waste is pulverised by a hammer assembly. You can vary
the consistency of material crushed by the hammer assembly by
opening or closing the adjustable screen.
When shredding soft material such as fl owers, shrubs and
leaves, the screen should be opened or closed depending on
the structure and dampness of the material. For terrain or
compost preparation, use the machine with the screen in the
open position. In this case, it is advisable to fi rst let the hammers
rotate so that soil-like material is processed using the blunt
side of the hammers. Th is protects the cutting surfaces of the
hammers. When crushing plastic, select either the cutting or
pounding surface of the hammer depending on the structure of
the material.
Use cutting surfaces for soft and fl exible plastic, and pounding
surfaces for hard or rigid plastic and also glass.
In accordance with safety regulations, the size of the infeed
opening is restricted. Accordingly, waste material should not be
forced into the opening but introduced liberally.
Ensure that the discharge port is uncluttered at all times.
Otherwise, the machine will immediately clog due to air
stagnation.
SHREDDING TIPS
• Th e shredded material should be neither too bulky nor
too fi ne in consistency; nevertheless it must be suffi ciently
crushed to favour the proliferation of micro-organisms .
• Waste card and cardboard (preferably moist in order to
accelerate the decomposition process) can also be introduced
into the hopper; the cutting unit is extremely heavy-duty.
• Damp material such as vegetable waste, sodden leaves,
shrubs etc. can be shredded without a problem: there is no
risk of clogging .
COMPOSTING TIPS
• Use a wide variety of garden refuse.
• Mix the waste material thoroughly and deposit it in layers.
• Mix grass cuttings with other waste to prevent mould
growth.
• Scatter micro-organisms (available in specialist stores)
amongst the shredded material to further accelerate the
decomposition process.
• Th e abundance of air and water facilitates the decomposition
process (by enabling the micro-organisms to fully develop).
• Avoid inorganic substances.
• Aft er several weeks, turn and sift the material in the mound
or composting container.
• Th e fi nal product is a rich humus which makes an ideal
6
organic fertiliser for the garden .
• Using this organic fertiliser avoids the need to buy costly
additives.

MAINTENANCE INSTRUCTIONS

WARNING - Switch off the engine and disconnect the
spark plug cap before performing maintenance and
cleaning operations, or before opening the hopper.
WARNING – For engine maintenance, carefully read
the engine manufacturer's instruction manual.
WARNING – Always use suitable tools and wear
protective gloves when performing maintenance
operations.
• Cleaning the machine: material which is stuck to the
shredding chamber can be removed with water. Dirt can be
eliminated eff ectively using a high-pressure water jet. Ensure
that the water jet does not spray directly onto the engine or
the engine switch. Once the machine is dry, all of the metal
parts of the machine may be lightly sprayed or coated with
vegetable oil to protect them from rust. Warning! Do not
use mineral oil or rust inhibitors which contain mineral
oil. Respect the environment.
• Regularly ensure that all bolts and screws are fully tightened.
Tension the V-belts at regular intervals (test the degree of
tension by pressing with your thumb). To tension the V-
belts, push the locking plate under the engine support using
the two M8 hex head bolts located above the discharge port.
Before doing so, you will fi rst need to loosen the engine
fi xing screws. Aft er tensioning, ensure that the pulleys are
aligned.
• Th e branch hopper has a fi xed angle of inclination. Th is
ensures that the material is drawn smoothly into the
shredding chamber. As soon as the intake force begins to
decrease, the planing blade should be resharpened. Th is
operation should be performed using water to prevent the
grain of the blade from burning and thereby becoming
brittle.
• In order to replace the counterblade or the planing blade,
the infeed opening must be completely detached from the
machine. Th e counterblade is secured with three countersunk
bolts and nuts to the mounting plate of the infeed opening.
• Replacing the cutting hammers: remove the belt guard on
the infeed side with the holding sheet which is secured above
the bearing. On the switch side, loosen the nut securing the
corrugated cover sheet and point the cover to one side so
that the opening in the side panel is uncovered. Open the
hopper and rotate the hammer assembly so that the elastic
plugs securing the hammer pins can be removed using
a cotter pin puller. Th en extract the hammer pin through
the side opening using a screwdriver or similar tool and
remove the hammers and spacer bushes one at a time. Be
careful not to switch the hammers and bushes: they must
be refi tted in their original position, otherwise the hammer
assembly may become unbalanced. Also take care to ensure
that the hammers pass through the grooves at the centre of
the adjustable screen. Refi t the components in reverse order
to removal.
• Replacing or removing the screen: the screen is secured to
the crank by two elastic plugs inserted one inside the other.
Remove the elastic plugs with a cotter pin puller. Ensure
that, as soon as the second elastic plug has been extracted,
the cotter pin puller performs the job of the elastic plug and
prevents the crank from rising unexpectedly. Keep the crank
in position and remove the cotter pin puller. Unload the
spring and remove it from the lock. Th en extract the crank
from the machine. Th e screen is now fully removed. Refi t
the components in reverse order to removal. When refi tting,
carefully ensure that the screen is correctly inserted (the
hammers must move freely inside the screen). Also make
sure that, when inserting the elastic plugs, the plug slots are
always oriented towards the direction of rotation, bearing in
