Trouble Shooting - HERKULES Schredder 4000 Profi Bedienungsanleitung

Changing sheer bars
If the sheer bar is worn, you can turn it over.
• Stop the engine and disconnect the spark plug or
remove the supply plug on electrically powered
machines.
• Lock the side hopper to the main hopper
• Slacken the sheer bar screws.
• Turn the sheer bar. If it is damaged or worn out,
replace it.
• Fully tighten the mounting screws.
After re-positioning or replacing the sheer bar measure the
gap between the cutting blades and sheer bar which should
be 2mm. If the clearance is greater, add spacers to correct.
Changing of cutter blades
• Stop the engine or remove the spark plug, or remove
the supply plug for electrically powered units.
• Remove the discharge hopper
• Tilt the main hopper backwards.
• Turn the hammer shaft by hand until side blade is on
top.
• Slacken the blade jacking bolt and remove it.
• Fold down the vertical and horizontal screens.
• Turn the hammer shaft until you can reach the blade
through the outlet.
• Loosen the 2nd blade screw and remove the blade
• Fit the new blade loosely with the outer screw only.
The cutting edge should be pointing downwards.
• Turn the blade into cutting position so that the blade is
now pointing upwards.
• Fully tighten the blade mounting bolts.

Trouble shooting

The unit does not start:
• Check the engine fuel or for electrical units the supply
plug fuse and supply.
• Check all the safety switches and ensure that they are
correctly installed as they will prevent the engine
starting. If you cannot solve the problem, please
contact your dealer.
The electric engine stops after short
period:
The motor could be over heated so that the thermostatic
cut out has operated. In this case, wait until motor has
cooled down and try again
If the supply plug is hot, please check the cable diameter
(5 x 1,5mm) and the correct fitting of the wires into the
plug.
Note:
Use only short cable with a conductor size of 1,5mm or
greater. Long cables cause both voltage drop and an
increase in current which way blow fuses
Engine will not run at full speed or gives
sings of distress:
• Check that the hammer mill shaft can turn freely and
clean the area to ensure that no blockage can occur.
• Correct the belt tension if necessary.
If the unit still does not work, please contact your dealer.
V-belt tension
You should check the V-belt tension more frequently
when the machine is new and then, thereafter, at regular
intervals of no more than 4 hours. The V-belt tensioner is
located towards the bottom of the machine and can be
accessed by slacking the lock nut. the tension of the V-belt
can be adjusted by taking up the tension of the screw
provided.
Chopped Material is too fine for intended
use:
• If the horizontal screen is refitted, remove it by folding
it down.
• Check the hammers. If edges are blunt, turn or change
them to sharp edges.
• If the side hopper is in use, check the cutter blades and
sheer bar. Sharpen or change these as necessary. Ensure
that the clearance between the cutter blade and sheer
bar is 2mm, shim to correct.
