To change a cutterhead from left hand to right hand
conguration:
1. Remove the protective cover (Item 5) and discard. Remove
the circlip (Item 7). Remove the counterweight (Item 6)
together with the ‘O’ ring (Item 9) and ret to the non-drive
end.
2. Tighten each of the two socket head cap screws and tighten
to a torque of 80Nm (59 lbs.ft).
Repeat steps 1 to 3 for the remaining cutterheads.
3. Fit the circlip (Item 7) to the drive end.
Note: It is important that the Circlip is tted to the
drive end.
When tting the cutterhead to a machine, the reel adjustment
hand wheel assemblies (Item 8) may require repositioning to
suit the application. Refer to the relevant Operator’s Manual.

assembly to the cutterhead frame.

and then remove the hand wheel assembly. Adjust the hand
wheel assembly to provide the correct fastening centres and
ret in the alternative position. Replace all fasteners and
tighten securely.
Repeat steps 4 - 6 for other cutterheads where required.
7. Attaching the MK3 cutterheads to the machine:
1. Unlatch and lower the relevant arm to the ground.
2. 250mm cutterheads only - Using the 400mm long
cutterhead pin already tted to the arm, remove the nut
cap, nut and washer from the cutterhead pin.
