UNBLOCKING CUTTING CYLINDERS

WARNING: PREVENT ACCIDENTS - Before attempting to clear any blockage from the cutting
cylinders on this machines ensure all of the following:
- Stop the machine on level ground.
- Apply the parking brake and disengage all drives.
- Lower the cutting units to the ground or securely lock in the designated transport positions.
- Stop the engine and remove the ignition key to isolate all power sources and check that they
have stopped.
- Release all stored energy devices.
- Check that all moving parts are stationary.
DO NOT ATTEMPT TO ROTATE THE CUTTING CYLINDERS BY HAND as there may be some
residual pressure in the hydraulic system which could cause injury through sudden movement of the cylin-
der(s) when the blockage is released.
Wear protective gloves and use a suitable strong wooden instrument. Ensure that this will fit between the
blades and through the cylinder and is long enough to provide sufficient leverage to release the blockage
and any residual hydraulic system pressure by rotating or rocking the cylinder. Make sure that the wooden
instrument is properly supported in the cylinder and avoid the use of excessive force to prevent damage.
Only when the cylinder has a degree of free movement should the source of the blockage be removed.
Ensure that the wooden instrument is also removed before restarting the power source.
If the cylinder requires readjustment or repair, refer - MAINTENANCE - Cutterheads.
