1.54 1.54 OPERATING THE MOWER
Unblocking the Cutting Cylinders
WARNING: PREVENT ACCIDENTS - Before
attempting to clear any blockage from the cut-
ting 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 are stopped.
- Release all stored energy devices.
- Check that all moving parts are stationary.
DO NOT ATTEMPT TO ROTATE THE CUT-
TING CYLINDERS BY HAND as there may
be some residual pressure in the hydraulic system
which could cause injury through sudden move-
ment of the cylinder(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
to MAINTENANCE - Cutterheads .
