Unblocking Cutting Cylinders Cont’d
NEVER 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 cylinder(s) when the blockage is
released.
Always wear protective gloves and use a suitable
strong wooden instrument. Ensure that this will t
between the blades and through the cylinder and
is long enough to provide sufcient 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.
Centre Cutterhead Height of Cut
Correction Adjustment
With all cutterheads set at the same HOC via the
indicator rings, it may be noticeable that the centre
unit produces a higher cut nish compared to the
wing units. The centre unit is pulled and the wing
units are pushed this presents marginally different
cutting angles relative to the ground. The amount
of HOC variation, which results from this will be
inuenced by the terrain but satisfactory results can
usually be achieved by setting the centre cutterhead
HOC indicator ring lower than the wing unit
settings.
