Drain Line
Run the machine to confirm that the blade rotation direction is correct.
Switch machine off and inspect the hoses and connections for signs of leaks.
Check belt tension before using the machine for work, refer to belt tensioning section.
Disconnecting
IMPORTANT:
The machine should be secure at all times when left unattended
so it doesn’t move. Ensure that
the machine is stored off the ground, preferably in a dry location to preserve its condition; for example on a
pallet.
Manoeuvre the reach arm attachment watching for bystanders and potential dangers in the vicinity to place the
machine in a suitable location for detachment. With the tractor switched off and secured in position on level
ground, relieve the hydraulic pressure from the tractor by moving the hydraulic control levers/buttons back and
forth several times.
When disconnecting the hoses to the tractor it is important to keep the hoses, and end couplings free of
contamination and dirt. Never disconnect a hydraulic hose and leave the coupling end exposed. Utilise blanking
plugs to keep them contaminant free. If any component is deemed dirty ensure that it is cleaned with some clean
rag.

Hydraulic Hose Checks
It is important that hoses are fitted correctly. Always check all hoses to ensure that there are no kinks or sharp
bends, and that the hoses do not chafe against sharp edges. The following guidelines should be used when
checking the hosing of the machine prior to work;
3.9.1
Twists
Hoses should never be twisted or kinked. On most hoses there is a line which runs the full length of the hose
acting as a useful guide. If a visual check reveals that no guideline is present along a hose, refer to Figure 3.6
and conduct the following check;
