2 Maintenance
2.1 Changing Cutter Drums
Turn off and stop the machine, making sure the cutter drum has come to a complete standstill.
If electric or air powered, disconnect the machine from the power source.
Adjust the height adjustment hand wheel so that the cutters are clear of the ground.
Remove the four Side Plate retaining bolts and remove the Side Plate. If the Side Plate is stuck in it’s
opening or on the dowel pins, use two of the Side Plate retaining bolts inserted into the threaded holes
on each side of the Side Plate. Screw in both of these bolts equally until the Side Plate is free.
With the Side Plate removed the Cutter Drum will simply slide off the Drive Shaft. The fitting of the
drum is basically the reverse of the removal procedure.
When changing cutter drums always check that the flail shafts are not excessively worn with
pronounced grooves, also that the centres of the cutters and spacers and that the drum flail shaft location
holes are not elongated. The screws which hold the drum end plates in position must be tight and in
good condition.
Note: In general use it is expected that normally two sets of flail shafts will be used to one set of TCT
cutters. While changing the drum the condition of the drive shaft, the drum’s hexagon drive, the drive
shaft bearings and side plate bearing should be checked. If any roughness, side play or leakage of grease
is detected then new bearings should be fitted. Lightly oiling the drive shaft will prevent a build up of
rust, which could cause difficulty when changing the drum later. While the Drum is removed, check that
the vacuum port is free from blockages.
Replace any damaged, worn or suspect parts. Ensure that all the bolts are tight at all times, recheck at
regular intervals.
2.2 Cutter Replacement & Configurations
Replacing cutters/spacers/flail shafts
Remove Drum; see Changing Cutter Drums.
Unscrew the four countersunk screws and locknuts from either end of the Cutter Drum.
Using a suitable drift, push out each of the flail shafts. Check each of the flail shafts for wear and
replace as required. Check also the Drum, Cutters and Spacers for elongation and hole enlargement,
replace as necessary.
See the table below for the examples of the sequence of spacers /cutters for each style of drum.
Before loading any cutters, establish which is “Position 1”.
Position two shorter rows to the left and at the top as you look at the drum; identify the short row on the
left furthest away from you (at the “back” of the drum), this is “Position 1”
For ease of assembly, mark the end of the drum to help identify each flail shaft, rotate the drum away
from you marking each position in order. 1,2,3,4.
